4x4 / AWD Sprinter and Transit Vans
4x4 / AWD Sprinter and Transit Vans - Cost, Capabilities and Compromises
Updated December 2023
So You Want a 4 Wheel Drive Van?
So you’ve decided you want a 4 wheel drive (4×4) or All Wheel Drive (AWD) van, so what do you get? Up until early 2020 the Sprinter was the only van that offered 4×4 from the factory. In 2020 the Ford Transit became available with an excellent all wheel drive (AWD) system. And as of the 2023 model-year the Mercedes Sprinter is finally available with a new AWD system to replace its outdated 3rd-party system. Here are some things to consider when choosing a 4 wheel drive van.
Do You *Need* 4 Wheel Drive?
The first thing you should evaluate is whether or not you really need 4 wheel drive. Let’s throw the cost out the window and assume you have unlimited money to spend. Where do you plan to use your van? Is it for use in the snow? Keep in mind that 4×4 can help get you started, but it will not help you stop or turn. If you want increased performance in snowy climates, a 2WD with winter tires will outperform a 4WD on all-seasons. As people who have only owned 4×4’s the past 20-years, that information surprised us. That said, four wheel drive will reduce the number of snow chain applications and will provide increased traction in slippery conditions.
When we ordered our van, 4×4 was on the “must have” list. As we became aware of the compromises in the pre-2023 4×4 system on Mercedes vans, we felt we had to skip it. In the past 6+ years of van travel and tons of offroad miles, we have found we simply don’t need 4×4. The height of these vans is extremely limiting. When combined with the limited ground clearance, axle articulation and lack of true 4×4 underpinnings, vans will always be somewhat limited their capabilities. On the public lands of California, Oregon and Washington, we often have to turn around due lack of clearance under tree limbs (due to the 9-foot+ height.) We find the vehicle height to be the biggest limiting factor offroad, not the number of driving wheels.
Is 2WD Enough?
We are not here to answer that question for you, however we are shocked where our 2WD Sprinter has taken us. We have 4WD vehicles (a 2000 Toyota 4Runner) and we frequently travel with friends that are former Jeepers. These 2WD vans have gone places we never thought they would go. We’ve been through wet Utah mud, up rutted forest roads where tires are lifting off the ground, pushed through foot-deep snow fields. We’ve been on trails where Jeepers were shocked we got a “4×4 Sprinter up there,” only for us to inform them they aren’t even 4x4s. Keep in mind we are prepared with tow straps, traction boards, etc, and recommend you do the same. In other words, making a choice to forego the AWD option is not going to limit you to Walmart parking lots.
The Cost of an AWD Van
The AWD option adds about $4,190 to the cost of a Transit and about $6,700 to the Sprinter. (Pricing as of January 2024.) Selecting AWD can also force more expensive powertrain options, such as the necessity for the high-output diesel engine the Sprinter. AWD vans have also been subject to increased markups from both Ford and Mercedes-Benz, further increasing the price delta between a 2WD and AWD van.
AWD Engine and Transmission Options
The Ford Transit AWD comes standard with a naturally-aspirated 3.5 liter gas V6 with 275 horsepower and 262 ft lbs of torque. Also available is a twin turbo 3.5 liter gas “Ecoboost” V6 with 310 horsepower and 410 ft lbs of torque. Both engines are backed with a 10-speed automatic transmission.
The Sprinter has two 2.0-liter 4-cylinder diesel engine options for 2023. First is a “standard output” turbodiesel with a single turbocharger and 170 hp and 295 ft. lbs of torque. The second option is a “high output” turbodiesel with twin-turbochargers (a $2,800 up-charge) that makes 211 hp and 332 ft. lbs of torque. All are backed by a 9-speed automatic transmission. Only the high output engine is offered with the AWD model.
The high output twin turbodiesel replaces the old 3.0 single-turbo V6, which made 188 horsepower and 325 ft lbs of torque. Not only does the new 4 cylinder diesel make more power and torque, it does so at a lower engine RPM. The new 4 cylinder diesel powertrain consumes 31% less fuel than the outgoing-V6 and has noticeably less turbo lag thanks to twin-turbos.
AWD Van Compromises
This article has been substantially revised since 2023. Prior to 2023, ordering a “4×4″ Sprinter came with a host of compromises and downsides, discussed later this article. Today in 2023, we don’t think these downsides exist. Beyond the increased purchase price of an AWD van and higher insurance and a few more maintenance items, we don’t really find there to be substantial downsides to purchasing and owning an AWD van. You’ll find the AWD Sprinter has a 4-1/2” higher step-in height than a 2WD, however Ford was able to retain the same floor step-in height with their AWD Transit. The modern AWD systems do not carry the same fuel economy penalty the original “4×4” Mercedes van had.
“4×4” vs AWD Systems
In the past eight years there have been two completely different 4×4 / AWD systems offered by Mercedes-Benz. The 2015-2022 Sprinter was badged on the rear door as “4×4” while the 2023-to-present are badged “AWD.” For the purpose of clarity we will categorize these vehicles as “4×4” and “AWD.”
The 2015-2022 “4×4” Sprinter
The first Sprinter “4×4” was available in 2015 in the United States and Canada and featured a third-party “engageable AWD system,” as Mercedes-Benz called it, capable of sending 67% of the engine torque to the rear wheels and 33% to the front. Despite the “4×4” badge on the rear of the Sprinter, a “true 4×4” has a locking center differential and sends the power 50/50 to the front and rear. The Sprinter has neither capability. The system was push-button activated and required the vehicle to be stopped and shifted into neutral, activated, then placed back into gear.
On a 2015-2022 Sprinter, pushing the 4×4 button engages the front driveline, but does not lock the front driveline to the rear. This is called an open differential. This means that power will take the path of least resistance. In this case, power is sent to the wheels with the least traction. An ABS-based traction control system is tasked with applying the brake on the spinning wheels in attempt to transfer torque. It is a rather effective system, however it’s limited in what it can do on very slick surfaces across an open differential only providing only 33% torque to the front axle. Electronic nannies reduce throttle input and the ABS system pulsing the brakes greatly reduces vehicle momentum.
Modern Sprinter and Transit AWD Systems
In contrast with the 2015-2022 Sprinter’s open center differential, a 2023+ Sprinter and a 2020+ Ford Transit AWD can intelligently transfer power where it’s needed. The AWD Sprinter is capable of a 50/50 power split between the front and rear axles, vs only 33/67 on the “4×4” Sprinter. The Ford Transit can send 100 percent of available torque to the front wheels or rear wheels, wherever it is needed. The improved torque-split increases traction and helps with engine-braking stability when descending slick surfaces, when compared with the old Sprinter 4×4.
The AWD Sprinter employs a hydraulically-actuated wet clutch pack to distribute fore-aft drive at up to 50 per cent to the front axle. Under normal traction conditions all drive is directed to the rear axle. An electronic control unit monitors front/rear wheel speeds and, if it detects wheelspin, directs drive to the front axle, within milliseconds. With the center differential now sending power where it’s needed, the AWD is less dependent on the brakes to stop spinning wheels. This helps maintain torque and momentum when ascending and also results in less brake wear. No need to stop to engage these systems, as was required in the older “4×4” Sprinter.
Known Issues with the 2015-2022 Sprinter “4×4”
The 2015-2022 “4×4” Sprinter had a number of downsides, including noise and significant vibration from the 4×4 drivetrain, finicky/unreliable 4×4 engagement, and lack of adequate torque transfer to the front wheels. Due to the design of the third-party center differential, if the rear wheels were on a slick surface, the van could be completely immobilized, unable to send power to the front axle. Unfortunately these conditions are the times you need power to all four wheels to prevent being stuck. You can read all about user experiences with this issue here. In addition, some front tire movement is needed in order for the 4×4 to engage. Be sure to engage the 4×4 before you need it, because once forward progress terminates (i.e. you’re stuck), you likely won’t be able to get the front wheels to roll far enough to engage 4×4.
4×4 engagement on the old 2015-2022 system has been troublesome for many owners. There are long and detailed posts on the Sprinter forum discussing the intricacies of getting your $70,000+ van in and out of 4×4, and 5-minute long videos on YouTube showing just how convoluted the 4×4 engagement process is.
2023+ AWD Sprinter
The new AWD addresses the issues in the older 2015-2022 system. The revised system features permanently-engaged AWD, making the finicky engagement problems of the old system a thing of the past. Being an in-house system designed by Mercedes-Benz and Magna, it is better integrated into the vehicle, reducing noise and vibration inherent in the old system. Power split of the revised unit offers a 50/50 split front to rear. This will provide more pull to the front end than the current 33/67 split system. This will help the Sprinter in low traction situations and engine braking while decending on snowy roads will be more controlled. Fuel economy and driving range are improved as the powertrain is more efficient.
Low Range Gearing
The 2015-2022 “4×4” Sprinter featured a low range that is not offered on either the AWD Sprinter or Transit. Worry-not though, gear reduction of those old units is only 1.42:1, which makes it the highest-geared transfer case in any production vehicle sold in the U.S. (Lower gear reduction is better.)
The “crawl ratio” of a vehicle is a measure of the effects of gearing in the transmission, transfer case and rear axle. The higher the number, the lower the gearing. A 2015-2018 NCV3 Sprinter (with the low range option) has a crawl ratio of 19.99:1. A 2019-2022 VS30 Sprinter, with it’s 7-speed transmission, has a crawl ratio of 24.38:1. The 2023+ AWD system, with no low range and the new 9-speed will has a crawl ratio of 21.7:1. That slots right in the middle between a NCV3 and VS30 Sprinter. In other words, the lack of low range does not significantly reduce the AWD van’s slow speed agility.
Sprinter Transfer Case Upgrades
The 2023+ AWD Sprinter has a much better integrated transfer case than the old “4×4” Sprinter. The photos below illustrate how low the old transfer case sat below the vehicle frame. The red line highlights the relative dip of the transfer case cross-members between the new AWD model and the old “4×4.” The “4×4” crossmember dipped below the frame, where the new AWD transfer case sits much higher and is much better protected, and results in an improved off-road break-over angle.
Would we Consider AWD in 2023?
When we ordered our van, we chose to pass on the compromised “4×4” system in the 2015-2022 Sprinter. Flash forward to today in 2023, Ford and Mercedes-Benz both make modern AWD systems that no longer have the problems and compromises of the previous-generation Sprinter system. With automatic engagement, intelligent power transfer, and no significant downsides, we would at least consider an AWD van from Ford or Mercedes. While we have not “needed” AWD to-date, it would be nice to have the additional capabilities and assurances that a permanent AWD offers.
Thanks for reading. No matter what you drive, be prepared and always carry recovery gear when venturing off the beaten path.

Ken, can you elaborate on the noise?
Hi Jim,
The first several pages of the Sprinter 4×4 subforum have multiple threads on 4×4 clunking, droning and vibrating. Here’s the subforum: https://sprinter-source.com/forum/forumdisplay.php?f=203
It’s really apparent when you drive a 2wd and 4wd back-to-back.
You can get a centre diff lock fitted by oberigner to the pre 2019 4×4 sprinter. this makes the four wheel drive system work like a true 4×4. The standard 4ets system doesnt send power to the front wheels till the back spin to 20mph. The only way to overcome this is to apply the handbrake to transfer power to the front wheels. I have a 2008 315 4×4 sprinter From new it was the worst 4×4 system Ive ever come across. Mercedes told me not to use it on wet grass as it would spin!!! Centre difflock fitted by oberigner 2012 Fantastic 4×4.
Bought a second sprinter 319 4×4 2014. Again had to have a centre difflock fitted before it would tow a tailor on wet grass. unfortunatley the axel ratios front and rear where incorrect. The noise on a dry surface was horrendous as it would not disengage the difflock because it was wound up tight . it took 12 month to get the axel ratios corrected.
I agree they are a noisy 4×4 system. I would by another with the difflock option as they are such a great looking vehicle and perform on the road well.
Good to know Bill! I’m wondering how they achieve that. The transfer case has planetary gears, so it seems like they would have to replace the transfer case completely. I’d like Oberigner to make a 4wd system for the 4 cylinder Sprinters and offer it here in the US. The fuel economy is too good to deny, not to mention the 7-speed tranny versus the 5-speed in the 4×4.
Hi Ken – any updated info on aftermarket options for converting a 2020 4 cyl gas sprinter to 4×4?
Thanks
Mark
A company by the name of Offhighway Van has a prototype system but I believe the front motor is electric. They had mentioned coming up with a standard 4×4 system in the future but I haven’t kept up with it. There is so much room for improvement on the Mercedes system that I have to believe some smart engineer will come up with a system like the setups available for the Ford Transit.
Planetary gear-sets are not complicated, they consist of a sun-gear, multiple planet-gears traveling around the sun-gear and a ring gear. Lock two sets of the three together and you have locked the diff.
Hey Bill
Which center difflock did you use?

3 sprinter all170 wb regular body no extended body all 5 speed 3.0 v6 The 2011 is a 2 wd and i have 2 2108 a 2wd and a4 wd. Driving the same speed with the same weight the 2011 because of different emissions stuff gets 19.5 mpg and he 2 2018 both get about 18. I dont see a difference in fuel mileage, noise level or anything in those sprinters. The 2018 2 wd i bought as a crew van and it still is the 2018 i bought as an empty delivery van 2 seats metal wall no windows, that is now a full blown camper van for the family.
And i have a few miles on it and i tried the 4wd in some snow and some mild off road and i am not unhappy with it. And also i got about 3 g off msrp and the promotion from mercedes was 5 y 100k miles bumper to bumper warranty and i got that on the 2wd and the 4wd the same …. so my additional cost with a 2 speed transfer case was about 7500 dollar …. real money….. and ao far so good – it all works satisfactory. Video on it to come.
I’m really glad that I found your article, its very informative. I was wondering if I possibly made a mistake by getting a 2WD Mercedes Benz Sprinter, but, now after reading this, I know that I obviously don’t need it and it’s not desirable.
If I need AWD…. I might as well use my Subaru Outback….
I imagine that the 4WD Mercedes gets worse fuel economy as well…
The reason I wrote the article was to highlight some reasons why choosing 4wd on a Sprinter should be done with intention as there are some pitfalls. For some, the downsides may be worth it; not in my case though.
As a 2016 4×4 sprinter owner I do agree with a couple of these points but also I feel like I need to clear up some things also.
-Bad
Yes no shift on the fly sucks, you have to be going less than 5mph.it is finicky to do also until you get the hang of it. The good thing is you can run it in 4×4 and it makes no difference in the way it drives. Maybe a slight whine but no loud noises and no binding when you turn.
-Bad
Hard to find, yes . I was lucky with mine and found it on a lot. Yes I agree the price can get out of hand but my cargo van with hardly any options stickers at 46000 and I got it for 44000.
-Clearing up a few opinions in this post that I don’t agree with
A 2wd van will go nowhere close to what my 4×4 will. I have pulled many many vehicles out of the ditch. Tires make a big difference with any vehicle.
Body lift? The van is a unibody, that’s impossible. The entire suspension is lowered down just like any i.f.s suspension lift in a truck or suv. This lift allows you to clear 33in tires stock. Bigger tires are the only way to get more ground clearance on any vehicle including solid axles. Portal axles are the only exeption
Noise? Not sure where this comes from but I guess I have never owned a 2wd sprinter. I do agree it can clunk if it doesn’t fully engage.
One thing you didn’t talk about was resale value. Sprinters rule this already but a 4×4 sprinter is about as good as anything less than an exotic sports car
Thanks Chris for your insight. I definitely agree that 4 wheel drive adds capability. The point of the article was to somewhat distinguish what you get when you order, say, a Toyota 4Runner, versus the system used in the Sprinter. As for the body lift, you are right. The rear lift comes from leaf spring lift blocks. The front lift comes from a subframe spacer.
Resale value is excellent. Until Ford releases the 4 wheel drive Transit in 2020, there is no other factory option other than Sprinter.
Thanks for the article Ken. You’ve re-affirmed my thoughts on this, in more detail. I have a 2015 Crew tall roof, 2wd. I bought mine new, and I couldn’t afford the 4wd at the time, otherwise i might have gone for it.
I’ve owned 4wd trucks, and rarely engaged the 4wd system just due to the fact that I don’t go “off-roading” as a sport. So, thru normal use working, and camping mostly in designated parks, I have gotten my Sprinter stuck only ONE time in the last 3-1/2 years and that was in my own yard, LOL! And it’s my daily driver.
I just think that unless you’re really into trying to get your vehicle stuck, and then unstuck for personal entertainment- the additional cost is not worth it for most people.
Also- thanks for all of your blogging and youtube videos! All very informative and inspiring as I work on my slow-paced build-out.
I would certainly like to have 4WD, but not the 4WD system offered in the Sprinter. Perhaps one day Mercedes will come up with a better system that isn’t riddled with so many compromises. In any event, thank you for the feedback and kind words! Enjoy that van of yours.
I bought a 2017 Transit that was in an accident on the right side. It was converted to a 4×4 by Quadvan and they will not tell us what parts were used in the conversion. They said for $30K they will send us the parts. Only need the front wheel assembly which would cost a fraction of what he is trying to charge. I have hear great things about Quigley and how they work with their customers when their is a problem or accident. I would highly recommend Quigley and no one should ever buy from Quadvan.
Thanks for sharing. We will see how much longer they can stay in business with practices such as that.
Another thing about Quigley…in your packet of materials you get a complete list of all the parts, including part numbers, that were used in the conversion. Only a handful of them are Quigley specific.
@ourkavan. The Sprinter is NOT 4×4. It is an AWD system. One reason why we went with transit quadvan over sprinter
Hi OurKaravan,
First off, thanks for the article. A few bits here and there I hadn’t read already. Second, you missed a few key points:
1) The single largest downside to owning a Sprinter 4×4 is that the diesel engine and it’s associated emissions system are a requirement. Diesel gets you better mpg, torque, but comes at a huge cost: you can’t idle the vehicle for any prolonged period or do a lot of city/stop-go driving, without rapidly increasing the risk of an expensive diesel particulate filter (DPF) replacement, error codes, limp home mode (LHM), and other assorted expensive repairs. When idling or in stop-go or on short-trips, the diesel system with a DPF essentially can’t “regenerate” the DPF. Regeneration occurs when the onboard computer senses soot build-up in the DPF, and begins pumping extra fuel into the engine in order to raise the exhaust temperatures to 1400F to burn up extra exhaust soot and volatile compounds. If you are idling or in stop-go, or only doing short trips, the engine can’t heat up to 1400F or it gets interrupted in the process (short-trips) so it terminates the regen, leaving all that fuel to “blow-by” down into the crankcase (Sprinters diesels even have an “HI” error code to indicate high oil level due to too much fuel accretion). To make matters worse, Sprinter diesels have an “exhaust gas recirculate valve” that literally sends exhaust vapors back into the clean air intake of the turbo, thereby preventing those volatile compounds from venting into the air (can’t do this due to EPA), but also sending that unburnt fuel and soot vapor back into the engine, where the cycle repeats. If you idle too often (say to power a dual alternator to charge your batteries), or you drive a lot in city traffic (stop/go), or you do short trips for prolonged periods (short commute to work/back for a year), your emissions system gets clogged. Mercedes does not warranty repair this if they can assign the blame to you for improper use of the sprinter. Owner’s manual warns about idling and short trips.
2) All of that is the real achilles heel of the sprinter. But Transit’s achilles heel? Yes, there is one, and it’s glaringly obvious: the rear shock mounts. I’ll gladly send you the photo I have from when I crawled under both a Sprinter 2WD and a Transit RWD with a measuring tape. You’ll clearly see the outrageously low 6.5″ clearance on the rear shock mounts. The Sprinter? 8.75″ on a 2WD model. For comparison, my 10-year old rinky-dink Mazda SUV (FWD) has 7.1″ of clearance, and I hit rocks all the time taking that car down 4×4 roads it was definitely not designed for with regular all-season tires (I’ve only been stuck once, took 2 minutes to get out, back up, run-and-gun).
I want a Sprinter 4×4, have an order I can place at -$500 MSRP with every bell and whistle in the book, but I’m stuck now and not willing to move forward after talking to sprinter owners who can’t idle, and the ones who understand how the system works, purchase a special Scan Guage II just to monitor when the turbo temps reach 1400F so they know a regen is happening and can keep driving for 20-30 minutes at highway speeds (pain the you know what). It does this every 550 miles if you drive it perfectly on highways, but anything like city/stop-go or idling, and regens become as common as every 300 miles, with owners terrified of idling too long or interrupting the DPF regen. I think the AWD Transit is now a strong competitor in my book, but I’d have to install a kit to literally cut the rear shock mounts, raise them, and get to 7.25-7.5″” clearance, then cut the wheel wells to allow larger tires, and hopefully at the end of the day just match the Sprinter’s 8.75″ with stock tires (up to 9.25-9.5″” or more on Sprinter with better tires).
There’s no clear winner, Sprinter diesel 4×4 gets MPG and range on a single tank but horrible exhaust system, Transit gets gas exhaust but MPG and range are somewhat limited. I did like your comparison on that point and maybe it’s closer to the Sprinter diesel than I estimated.
Cheers.
Mark
I don’t disagree. Honestly the MB was never on my radar. But the quality problems of the Promaster and the Transit led me to believe I will get better service from the Sprinter. I think the Promaster’s engine and transmission problems are known, however I am an active member on the Transit forums and they also have issues with the driveshaft (guibo joints), cracked and warped exhaust manifolds on the ecoboost, more transmission problems than I would like to see, but most of all, engine valve deposit problems. The latter is common to ANY gasoline direct-injected engine, not just the Ford. It’s why other manufacturers have moved from direct injection to dual injection. Even Ford has made the switch on their upcoming engines, but they haven’t yet done it to the Transit. I personally wouldn’t buy a vehicle that had a direct injection-only engine.
And you’re right about the exhaust emissions systems on the diesels. When you choose one of these vans you really do have to pick the lesser of the evils. I personally would rather my van needed external exhaust sensors replaced than it needing the heads pulled or transmission overhauled. It’s too bad Toyota doesn’t import a diesel highroof van into the US, as then we likely wouldn’t have to make such difficult choices when choosing a van.
Thanks for the comment.
Where in the MB Sprinter manual say not to idle them? I have a 2017 Sprinter with an adjustable idle so I can set it higher than the standard idle speed. The manual mentions that if you idle or stop and go a lot that you should then drive it on the highway for 35 mins. I believe that was all it said about idling.
Hi, @Ourkaravan, What do you think about upcoming 2020 Transit? Its engine is still direct injection, right? Would you buy one over Sprinter?
If I wanted AWD/4WD, I would definitely buy the Transit over the Sprinter. I don’t think the MB setup is a good one at all, from the hardware used, the implementation and down to the spacer/rear axle block “lift kit.”
I absolutely love the 4 cylinder diesel in my Sprinter and it’s a shame it’s not currently available, but the 2020 Transit will have a 4 cyl diesel available. Unfortunately for us, not with AWD though. That would be the dream-team setup for me.
And yes, I understand the new Transit engines will have dual injection. That eliminates one of my biggest concerns with the pre-2020 Transits.
I can’t decide if I should buy a 2020 Transit AWD or Nissan NV 2500. NV has great reliability I heard, and I have also heard the problems with the Transit you mentioned, but I want an AWD.
If you want AWD your only options are Sprinter or 2020 Transit.
What about the Iveco Daily?
https://www.iveco.com/en-us/press-room/kit/Pages/Daily_4x4_detail.aspx
I’m unfamiliar with it. Is it based on the Crafter?
No not at all, it’s Iveco’s own chassis. 3.5t, 5.5t or 7t GVW. Bit of a beast and available as a panel van or chassis cab (single or crew)
https://www.iveco.com/uk/products/pages/new-daily-4×4.aspx
https://www.youtube.com/watch?v=mE166UG-R8c
OH, when I googled it a van came up for some reason. That does look like a beast. Be sure to let us know if you get one!
So how about with our 2018 transit we simply raise and add some beefy snow tires for over here in Hood River, OR. Already stuck once in the sand and has us worried with no weight in the back. I do hesitate paying big $$ to add 4×4 to our Ecoboost transit but if you’re a fan of Quadvan we may go for it. Tough call!
It is a tough call. I have a very nicely built 2WD van for the same price (or less!) than many people are paying for an empty 4×4 Sprinter cargo van. I would not spend the money unless you know you need it. I’m an off-road guy at heart and find that my 2WD has been able to take me everywhere I want to go. It’ll just depend on how you use your van.
Big Bill. Could you please tell us a bit more about the oberigner center diff Lock. I have a 2012 4×4 and would be very interested in price, diffculty in fitment and performance etc
You mention 4×4 or AWD for off-roading. I’m more concerned with driving on snow and slick conditions so I can take my van skiing. I’m starting to shop around so really leaning towards the 2020 Transit with AWD, the other option is, of course, the FWD pro master, which may be equally good in the snow. Any opinions?
Greg, the aspects of the Sprinter 4×4 system that limit it offroad–the 35/65 torque split, non-locking center diff, etc., aren’t as big of a disadvantage for use in the snow. Having some drive to the front wheels is helpful in snow, and the fact that the center diff is not lockable means the traction control continues to operate even when in 4WD, which is a good thing.
That said, you’ll be forced to live with the vibration and noise the Sprinter 4×4 system makes all the time and deal with the high step-in height. You might be better served by the Transit AWD. That said the Sprinter 4×4, aside from the noises and vibrations, reportedly works fine in the snow. However in difficult situations the open differentials will send power to the wheels with the least traction.
I now have a 2WD 2019 Diesel, and took it into the snow this past weekend the first time. I ski a lot. I live in California, where I’m found backcountry skiing in Tahoe, Shasta, Lassen, the East Side etc. I hate regular cable chains where you have to virtually crawl under the car, so I got myself a set of Spikes Spider hub chains. Putting them on take less than a minute, and I guarantee you can keep your hands clean. There are other manufacturers like Koenig. Friend of mine with a 2WD has those, and is very happy.
So, coming from an Audi A5 and a Mercedes M class, I will admit that I had my moments this weekend where I hated not having 4WD. Those moments where you drive to town, but there really is no snow, so you have to take the chains off for 3 miles of driving on asphalt. Or when I got stuck on an icy road in town, or on my ice driveway where I just couldn’t move with the 2WD and had to put chains on. Or when one of the chain elements broke because I had not adjusted it right, and the chain was rattling which possibly damaged it. I had to change my weekend plans and missed out on a day of snow. At the same time, I also remember having put on my Spikes Spider’s on my Audi in an absolute blizzard up I-80 to Tahoe, where I did not feel safe with the Quattro 4WD alone, but was cruising with the 4WD and chains.
But I digress: I drove up my 2WD with the stock all terrain tires (Michelin Agilis LTX) and the chains on the back, and the van performed really great. It was very stable, and the only time when I noticed the difference to 4WD was going up hills when I felt the back slowly pushing to the side, and on curves when I took it with 35 mph and had to slow down. Other than that, I felt really comfortable. There was never any moment where I felt that the 2WD would suddenly swing around.
In the end, it’s a trade-off. I am getting about 20 mpg on the 6 cylinder Diesel on the freeway, and the drive is real smooth. I have never driven a 2019 4WD to compare it with, but I take Ken’s word that it can be noisy. But the price is the major factor. I did not want to give up on some of the really cool Premium Plus features that the 2019 offers, such as adaptive cruise control. It is almost like autonomous driving which is so valuable on congest California freeways and even stop and go. Or the really cool 360 degree camera. Or the somewhat more luxurious interior that can’t quite keep up with my Mercedes ML, but at least it makes me feel less bad about trading it in. And the fact is that in California, I will need to drive 300 miles on regular freeway in order to get to snow, and that it doesn’t hurt me to put up with the slight inconvenience to put chains on for the last 30-50 miles.
Would I would like to have a great 4WD? Absolutely. Would I be willing to give up the nice 2019 features in order to afford it. No. Would I be willing to spend >65k MSRP for those features plus 4WD? No, I really cannot afford that. So, I will keep dreaming of a future when the Sprinters come with an upgraded 4WD technology, and I will be able to afford it. Until then, I will happily drive my 2WD into the snow, and you really shouldn’t fear that it puts you at a great disadvantage. We will get real Three Peak Winter tires for the season, and it will be even better.
Thanks Michael for your experience with the van. Like you, my past vehicles have all been 4WDs. Had the Mercedes 4WD been both affordable AND a well-engineered system without a bunch of downsides, I’d have one as well. But so far the 2WD has not held me back one bit. Enjoy that van, and maybe we’ll bump into one another running up and down I-80.
Great article! Hopefully it wakes some people up to the fact that not all 4 x 4 and AWD systems are created equal. Also would be nice for people to realize that asking a van to perform well in adverse conditions or off-road places is probably not going to happen and may easily lead to trouble or even disaster.
Regarding the coming of the Transit 10-speed and AWD, I have to laugh. The troublesome Ford 10-speed tranny is the subject of a class-action lawsuit. It’s first-year iteration in the Transit, coupled with an AWD system is a predictable mess. To those foolish enough to purchase it, I say good luck.
4zfed….I hope not…heading that direction. I dislike extended warranties, but have them on three commercial F350’s that have all paid off. Transit and an extended warranty here we come.
Ordered a stock 170″ Sprinter 4×4 that I plan to DIY before I ran into this article. A friend of mine is a good transmission and suspension specialist who can change anything that isn’t working for me. Not that I plan to do a ton of off-road driving, but where I live it is useful every now and then. The factory is building it this month and I should have it by the end of the year. I appreciate the blog and I plan on using some of the same elements in my build.
Some good shocks help the rocking motion quite a bit. Once I have a few more miles on my van I’ll spend the money on some upgraded Koni, Fox or Bilstein shocks. Enjoy your build and good luck!
Hey
I have a 2014 sprinter crew with the 4 cylinder Diesel and have done all of my own conversion . I’m still working as an electrician with the van. The van has 163,000 miles an I take very good care of it and I couldn’t be any more satisfied. But as I’m going to retire soon an I ask the question do I need a new van and should it be a 4×4? I have a dealer with a 2020 4×4 that I can build that goes to production in January that I can have for delivery by May and I can do this all over again . I will also note that I have watched most of your videos and I like what you have done and have copied more then one of your ideas. So that do I do is the 4×4 a good choice ?
Thanks Paul
Personally, I think you’ve got the best powertrain MB ever put in the Sprinter. There’s no way I’d trade a 23-27 MPG rig with a great powertrain for a 15-16 MPG 4×4 *unless* you found you needed 4×4 frequently.
Any thoughts on the Ford Transit all wheel drive versus the 4×4 conversion? I want to get the 2020 transit with the 2.0 diesel but my big hang up is trying to decide if I want 4×4 or just get the all wheel drive and put a little lift on it (or not)
If I were in the market for a 4×4 I wouldn’t even consider the Sprinter, I would go straight to the Transit.
Quick addition to my previous snow experience. Took the van up to Bear Valley/Hwy 4 this weekend after a decent amount of snow fell overnight. We decided to invest in a set of dedicated snow tires (Bridgestone Blizzaks). I had also weighted down the back with 150 lbs. Result: On snow packed surface, no chains were necessary. Technically, I would have to put them on, but I just kept driving since there was no chain control. I had no problems. On the downhill, it felt awesome to simply drive in a group of 4WD SUVs. The only problems I had was uphill in slushy snow and on the icy parking lot. The traction control did its job and slowly moved us forward. The other part was making a turn where I had a brief moment of slipping, but gained traction quickly thereafter. My summary: 10k is an awful amount of money, but it is an expensive vehicle already. Part of me thinks that I should have made the investment of 4WD, just to have the option. But even with RWD, it is a very capable snow vehicle, so my buyer’s remorse is manageable, but still intense at times 🙂
I feel some remorse as well, but I remorse Mercedes not making a better 4wd system. The noise, vibration, lack of a locking center diff and the torque split are all deal-killers for me. Also, this might make you feel a little better: https://sprinter-source.com/forum/showthread.php?t=54226
Mercedes sold two versions here in South Africa (and possibly in Australia too) until late last year, one model the AWD version described above and another version that is fulltime 4×4 with low range, three diff locks (front, centre and rear), very capable and this version was marketed with the 315 diesel engine, a bit underpowered though, both this model and the AWD was converted by Oberaigner for Mercedes until about 18 months’ ago, subsequently Mercedes decided to build/convert themselves, doing only the AWD, there is also another Austrian firm converting 4×2 models to permanent 4×4 as Oberaigner, they are called Iglhaut
Thanks Hiki for the comment. Until I read this article: https://newatlas.com/la-strada-regent-s-4×4/58229/ , I was unaware that Mercedes even offered a capable 4WD system in the Sprinter. But in looking through the comments I see it was mentioned before.
Even though my other 4WDs have had locking center and rear diffs, I could live without those. But in the absence of either a Torsen-style (torque sensing) center diff or the ability to lock it, I don’t really see the point. The Sprinter is only 4WD up until the point it gets stuck, then all it can do is transfer power to the wheels with the least traction and try and overcome that with the brakes. The 33/67 torque split doesn’t help get that power to the front at all. And then there’s the noise and vibration. Oh, and the astronomical price tag. Even the upgrade from a Porsche 911 Carrera to a Carerra 4 (the AWD version) “only” costs $6,000 versus the Sprinter’s $7,800…the latter offering the least feature-equipped system of any 4×4 ever made! Sorry, rant over. Enjoyed your comment!
Great article and some really good comments. I’ve really enjoyed watching the YouTube videos of your build and some of the bits and pieces I found really helpful. I own a 2019 170 4X4. I live in Calgary, Alberta, Canada where we get real winter. I primarily use the van for outdoor pursuits and backcountry access, whereby I am frequently on old logging roads, in unplowed situations. As such, I need any advantage a quasi-4X4, or otherwise can provide. At this point, I’ve used the 4X4 mode on the hiway and going up old roads to go snowmobiling or skiing etc. I’m not into taking a $90,000 van into crazy off road situations, but I do go places that require four wheel drive due to snow and ice. I haven’t noticed any clunking or whirring or anything perceptible from the “fake” 4 wheel drive. In fact, I’m quite happy with what the overall package has offered. In my opinion, this is a vehicle that is a cargo and people hauler, not a crazy mud-bogging off roading machine. Its a lighter duty luxury cargo hauler. If the vehicle lasts 300-500,000 KM, I’ll be happy, as every vehicle I’ve owned (Toyota, GMC diesels, Ford diesels, Nissan, Chev Surburban), ALL FALL APART and are prone to become scrap after 250,000km…. What we are talking about it simply our preferences and making a choice based on the best available info at the time, and frankly dealership reputation, and overall likability. At this point, my sprinter has exceeded my expectations, and it doesn’t fall short as a 4×4 in my opinion. Thank you again Our Kara Van! I really appreciate your carefully crafted and well thought out videos. Well done!!
Thank you, I appreciate the thoughtful comment. I also appreciate having some positive feedback on the system. Having some pull from the front tires does help stability in the snow. The issues described above are revealed as traction disappears and the torque split and the three open diffs (center, front and rear) are unable to move power where needed to free a stuck vehicle. The goal is to never be in that situation, right? 🙂
You live in a beautiful place. I’ve only made it as far north as Bluerock Wildland Provincial Park but will likely hit Banff/Jasper etc in 2021. Thanks again and enjoy your van!
Thanks for the thoughtful review of the factory 4×4 vans that are available right now. I had always wanted a 4×4 van but never thought that an aftermarket option would be very trustworthy. So when MB released the Sprinter with factory 4wd I knew that would be the van for me. I was able to find a low top 144″ 4×4 crew van and took delivery at the end of 2017(before the Transit AWD was available). I was initially shocked at how poorly it performed in the snow, but soon realized that the stock tires, though rated 4 season, are absolute junk. As soon as possible I had some Cooper M+S with studs mounted. Now I have to say that the Sprinter is our “go to” for mornings charging to the ski area to get first chair. It tracks like my wife’s Subaru Forester, and stops faster, but with room to get changed inside and visibility on the road like nothing else I have ever driven. The best part is that we engage 4wd at first snow of the year and take it out in the spring. Unlike traditional 4×4, there is no damage done driving on dry pavement. No weird tire wear or binding/chirping if left in 4wd. Because of this, IMHO, shift on the fly is not necessary, this took me awhile to accept. Comparing to traditional 4wd is like apples and oranges.
Never experienced any NVH noises or clunking that you refer to as commonplace, maybe we just got lucky, IDK.
Just wanted to share my experience and wouldn’t hesitate recommending this vehicle to anyone that drives in snow/winter conditions often, it’s the best (With proper tires)!
Thanks for the videos of your build, I have tackled a number of projects on my van with confidence because of them!
Cheers from Southwest Colorado!
Mike, thanks for the comment and I am happy to hear the van is working well for you. I agree with leaving it in 4wd for the winter, as you will avoid that situation where find yourself stuck and unable to engage it. A friend of mine found himself in that situation his first winter with his van and has been using your method ever since.
The NVH noises are more pronounced on some vans than others. I have linked to my sources where the issue is discussed and it’s definitely a thing, but some people care more about it than others. Living in Colorado I imagine it’s only a minor downside compared to the convenience of not having to chain up.
Thanks for the kind words and hope to see you back on ourkaravan.com! -Ken
I almost purchased the AWD Sprinter. Having read various reviews online it would appear that the Volkeswagon Crafter 4 motion is a more capable AWD vehicle, as they offer a rear lock differential option, plus you don’t need to slow down to engage the AWD system.
I much prefer a system like that found in the Crafter and would have bought it in a heartbeat if it were available here in the U.S.
Fantastic article. Greatly appreciated.
JM
Great article. I found it because last week I got stuck in some axle deep snow in the high country in my 2017 4×4 (with low range) Sprinter Crew van, note: with factory tires. The van stopped as I hit the deeper snow and shortly thereafter, the right rear wheel began to spin. With the low range engaged the traction control is disabled and the torque split is supposedly 50 front/50 rear. I figured that the drive train logic would brake the spinning wheel, move power to the other wheels and soon discovered that was not the case. The van was stuck, and due to the open differentials front, intermediate, and rear, all the torque continued to be sent to the spinning wheel. Next time, I would probably cinch down the handbrake to stop the rear wheels before getting out to install the chains. But, I got out and installed the front and rear chains I carry and drove right out of the snow…but I am convinced that I could have done the same thing in my 2011 2wd Sprinter. Afterwards, I studied the Mercedes system more thoroughly and discovered that it was nothing like the 4wd systems I am used to in my Jeeps. It is really a selectable AWD system, and there is not an aftermarket option to fix these shortcomings to make it a true 4×4. My next step will be to buy some better tires, probably BFG AT KO2s. But…knowing what I do now, I’d probably stick with a 2wd system with high quality tires and chains for a pinch. The 4×4 does allow me to cross the snowy mountain passes here without putting on chains, where I would always chain up the 2wd van in those conditions…but, you have correctly stated that this is not a 4×4 system, it is an AWD traction enhancement and should be driven as such. Do I like owning this 4×4 Sprinter…yes. Is it the bees knees…no, though I haven’t noticed any significant difference in noise between my two Sprinters.. If anybody makes an aftermarket locking intermediate or rear differential option, I will buy it and install it to improve the performance of the vehicle.
Thank you Donny for taking the time to write. Glad you got out!
The biggest difference between what you’re used to and the US Sprinter is the lack of 50/50 torque distribution but mostly the inability to lock the center diff. When you’re driving in 4wd there is a fixed 33% of the torque going to the front due to the planetary gear set. That changes when you put the van in slick conditions, when the tire with the least traction is where the power goes. The brakes attempt to sort it out but it’s an unsolvable math problem (the old 0 times 0 is still 0) when one tire is on a very slick surface. A standard 4×4 with a locking center diff will never be in this position because there will always be a fixed 50% torque going at least one front and one rear tire, with no exceptions, due to them being mechanically locked together.
We need to start riding Atlas to come out with a true locking center diff for the Sprinter so it has 50/50 drive when it’s needed most. Take care! Ken
Hi Ken –
I went through a similar analysis when choosing my van, and agreed with your observations – the current 4×4 setup is simply not worth it. I’ve also had several bad 4×4 experiences with other vehicles (meaning, getting stuck. Easily.) that I’m now more of a nay-sayer than anything else with respect to that always-very-expensive-and-not-that-practical option. Especially, since the great 2.1L powerplant was never available on 4WD, the biggest Sprinter advantage (crazy good fuel economy) is completely lost.
I wanted to chime here though because there actually IS a true hardcore, aftermarket off-road solution for Sprinters (and others) that WORKS, but is seldom touted, yet ends up costing much less than the $14k 4wd upgrade, maintains whatever drivetrain you want, AND (again, my opinion here) really steps up the look factor:
1. lift the van $1.8k (see, e.g., https://vancompass.com/collections/sprinter-2007/products/van-compass-striker-sprinter-van-2-0-suspension-lift-system-2007?variant=25286423619. There are other good ones too)
2. upgrade the suspension (about $750)
3. … and, for the key off-roading add-on: install a 5,000lbf WINCH at the front!! (about $2k for a Sprinter, with bumper adapter and everything).
So, about $5k. Never get stuck again.
It’s on my Christmas list 🙂
Pat
Hi Pat, thanks for the message. I did a ton of research before I decided NOT to get the 4×4 option. I don’t need the false sense of security of a 4wd system that is finicky to engage and can’t put power to all four wheels when it’s needed most.
I love the look of the 2″ lift on the 2WDs. I plan to do the shocks at a minimum, and I have had my eye on that kit as well.
Thanks for visiting and for the comment. And be sure to shoot me a photo when you get the lift. 🙂 -Ken
Hi Ken, awesome article, thank you. I drive a 2016 2wd Transit. I would love to get the quigley/quadvan 4×4 but it’s just too expensive for me.
How do you feel about the capability of getting an ARB Air Locker in the transit rear 9” as an alternative? That plus a van compass 2.5” and tires/wheels might run me ~$3,500 if I install it myself.
Mostly looking to get down to some beach spots & sand roads for surf trips. Does the locker/lift setup add some real capability?
A locked rear adds a good amount of capability. Ive climbed some hills in my 4Runner with the rear differential locked, made it to the top and realized later I never had it in 4WD. In some situations like snow it’s beneficial to have some pull from the front end, but my experiences around the Sprinter 4×4 have not been very good, particularly when traction at one axle becomes limited. I would invest in a rear locker for my Sprinter, but I understand it’s not possible to fit one. -Ken
Hello Ken –
THANK YOU – You have given us so much useful thoughtful information here! We decided to go with 2WD for our 170 Sprinter now, but I see you are driving a 4-cyl but you are in a 144″ WB, correct? Would you think the 4-cyl would work just as well for a built out 170 WB? Our build weight will be about 1800 lbs, and payload about 1700 when all tanks are full, fridge is full, two adults and a 37-lb-ish dog and professional camera gear for us both. We don’t want it to strain or take too long getting up hills, like Yosemite Pass from Lee Vining, or Going to the Sun Road in Glacier NP; nor would we want to be straining or lugging going up dirt road hills, and being 2WD we’d want it to be enough engine power to pull us along pot-hole filled dirt roads, like in Escalante (thought not gnarly 4WD roads). Appreciate your feedback on this! keep rollin’, Brenda
Hi Brenda, the 4 cylinder is great. The 7-speed does a great job of keeping the engine in the power band and the first gear is low enough that I haven’t had any struggles on dirt roads, even steep ones. I’ve done all the roads you’ve mentioned–Going to the Sun, all the grades on 395, the Burr Trail switchbacks in Escalante, and the van always pulls the hills well. I would have no concerns with a 170. To be clear, if it weren’t for the 4 cylinder diesel powertrain I would probably buy a Ford Transit. Diesels in general aren’t quick to quick to speed, but they pull hills really well. -Ken
Much appreciate your detailed review and analysis. I offer a completely different conclusion. First of all I have no interest in buying a brand new van and then having to spend $13K in aftermarket modifications done to the drivetrain, suspension, etc. Secondly, there are plenty of videos on YouTube of 4×4 Sprinters running thru all sorts of extreme off road conditions including very rough, bumpy roads and steep hills with loose gravel, slick mud, etc and the 4×4 offers the ability to NOT get stuck compared to the 2 WD. Does the Sprinter 4×4 offer the same offroad performance as a purpose-built 4×4 off-road vehicle such as a Land Cruiser or Jeep? Of course not, it is a van after all and frankly I am thankful I had an option for whatever 4×4 capabilities I could get even though I have no intentions of taking my expensive van thru extreme offroad conditions. I’m content with being able to get unstuck out of sand at the beach or up a slick, muddy hill is about all I hope to ever get into. And any experienced 4×4 driver in rough (sketchy) conditions knows you ALWAYS engage 4×4 BEFORE you think you might need it, before you try to go up the hill or thru the mud hole, NOT AFTER you are stuck, so I see little advantage of “on-the-fly” ability to shift into 4×4 mode while moving through rough terrain.
All the “theoretical” disadvantages of open vs locked differentials, 33% or 50/50 front wheel torque split, etc are fine on paper but one reason I bought my 4×4 Sprinter is due to seeing it in action rather than apparent shortcomings compared to more robust 4×4 type vehicles, as well as the ability to have on-demand 4×4 not full time AWD. Vans have a lot of weight on the front wheels due to the engine location so 33% torque is likely all that is needed due to the concentrated weight over the front wheels. Suggesting this 33% torque is not enough torque being directed to the front wheels is suggesting the Mercedes engineers didn’t know what they were doing and I am doubtful this is the case. The 33/67% torque split was likely a deliberate engineering design feature rather than an oversight or limitation. In addition, the improved fuel efficiency of on-demand 4×4 and longevity of diesel engines is another deciding factor that made me go with MB.
And my shopping experience was not the same as yours on the purchase. The 4×4 option is $7975 more than 2 WD, as you mentioned. I negotiated $4K off the MSRP on my 2019 4×4 Sprinter along with 0% / 60 mo financing and 50% off on extended warranty so I have full bumper-to-bumper warranty for 5 full years with zero deductible, lots of peace of mind there. So my cost was $8K not $14K for the 4×4 option. This discount was not due to poor sales or excess, unsold vans sitting on the lot, my dealer sold 200 Sprinter vans in June so they are flying out the door as fast as they can get them. The other Mercedes advantages such as fit, finish, styling, diesel fuel efficiency and much better resale value (less depreciation) of Sprinters all led to my decision to go with the 4×4 Sprinter over the 2 WD Sprinter as well as Ford and Dodge, which weren’t even a consideration.
Hi Craig, I appreciate you sharing your experiences with others. I noted in the article that since the introduction of the Transit AWD, Mercedes has been more willing to deal on the Sprinters. Thankfully that brings the cost a bit closer to the $7,875 option charge vs the significant price gouging that was occurring a short time ago.
The non-locking, torque split transfer case is one place we will have to disagree. I’ve had too many experiences in the backcountry where the 4×4 has done fine, until it wasn’t fine. On a snowy climb up to a hot spring my buddy’s 4×4 Sprinter struggled on a climb that had snow and ice on just one side of the road. That was after I drove up just fine in 2WD. We were curious what went wrong so he went back down the hill and came back up in 2WD and struggled less than when he was in 4×4. Repeated the climb in 4×4 with the same experience. I have my theories why it performed that way–in 2WD the traction control only had to shift power to the wheel not on the icy side of the road, while in 4×4 the computer was trying to brake multiple axles through 3 open differentials and a torque split. All the braking and power shifting was causing the van to momentarily stop on the hill while the computer sorted things out, which didn’t happen when he was in 2WD.
I have also had to recover a family stuck in the snow in a 4×4 Sprinter, using my 4Runner. It said 4×4 was engaged on the dash, however there was zero evidence of power being provided to the front axle as I towed them out. And of course my involvement in the Sprinter community presents a lot of opportunities for discussion, and the inability to move power to the front “really is a thing.” Hopefully you don’t encounter those.
Again, I appreciate you commenting so others can consider what has been written. Hope to see you back regardless of our differing opinions! -Ken
Thanks Ken for your reply. I appreciate your “real world” experience with this compared to me with none yet.
I am curious, in the situation the family was stuck in snow, it is my understanding that on the 4×4 Sprinter to engage the front differential you must roll forward a bit after stopping to engage 4 WD. If you wait until your back tires are spinning and you cannot move forward, then engage the 4×4 true I bet it will not move power to the front wheels. If it were me as soon as I got in the van and was planning to drive on snowy or muddy roads, flat or hills, I would engage the 4 WD not wait for a hill or until the back tires are spinning or stuck. My primary reason for getting the van is to go to warmer climates in winter and cooler climates in summer not to do extreme 4×4-ing. No doubt the 4×4 in the Sprinter is not perfect but it’s also not imperfect enough to push me to an AWD van of a different brand. This is due to the numerous advantages of the Sprinter during the 99% of time I am not needing 4 WD and IMHO this far outweighs what may be minor imperfections in the Sprinter 4×4 or its computer algorithm. I’ve seen enough YouTube videos of people testing their 4×4 Sprinters in 4 WD to convince me that it is sufficient for my needs, like this one https://youtu.be/3zTjeRRfGmU. One day I hope to get a Land Cruiser overland vehicle to go to the backwoods or hard to reach areas but I have no plans to destroy my new $60K van and all my internal camper van build-out by taking it 4-wheeling and shaking stuff to pieces. Peace! 😁
Hi Craig, in the case of the family stuck in the snow, it was already in 4wd when I started helping. It said “4wd active” and the light by the switch was on. However the entire time we were rocking it to free the van, never once did a front tire spin. It’s a common issue, and I linked to a thread on Sprinter Forums where others have noted the same occurrence. This occurs because the three open differentials (mainly the open center diff) can’t push power where it’s needed in some scenarios. I have owned nothing but 4wd’s the past twenty years, and even though I’d love a real 4wd/AWD system, I honestly can’t say that 2wd has held me back even once in the 3.5 years I’ve been traveling with the van. I have done many hundreds (possibly thousands) of miles on dirt roads and trails, and it’s usually the van’s height that limits me. Posts like this one posted today: https://sprinter-source.com/forums/index.php?threads/87502/ come up more often than any of us would like, and they pretty much reinforce everything in the article regarding the issues with this system. I will say not all the vans have the extreme vibrations and droning, but many do. The point of the article isn’t to product-bash, clearly I love Sprinters, but it’s to make people aware of the common issues. Take care and I hope you enjoy the heck out of that van Craig.
That was a very interesting read.
I’m looking for a new van in the UK. I want 4×4 for extracting the van from muddy fields and sandy tracks where I’ve been stuck with 2xFWD before. Sprinter would be my preferred choice as the aftermarket parts selection seems superior to that available for Ford or VW. My local Mercedes dealer has zero information on 4×4 Sprinters…. really… zero. I’m not even sure they know what a differential is. I’m not going with Ford, they are cheaper to buy, but feel cheap too and don’t have the selection of factory options that I want. That leaves the Sprinter or the VW Crafter.
I like the 3L V6 option for the Sprinter, the best VW offer is a 2L twin turbo, but I’ve had bad experiences with VW turbos.
It’s a minefield. No one can tell me if the Euro version of the Sprinter has these problems. I found mention that Euro versions have might have 1,2 or 3 locking differentials. The Crafter is better value but I don’t really know if the 4Motion system is better. Again, I know I can spec a locking centre differential on the VW, but I’ve also found mention that it may or not also have a locking rear diff.
I understand your concerns with the VW engine, however the 4Motion system is good. It’s everything the Sprinter isn’t…full time AWD, smart center diff that can transfer power where needed, no finicky engagement, no getting stuck in 2wd and being unable to shift to 4wd. 4Motion is available with a locking rear diff too, which is huge. I think Mercedes will have to come up with an updated 4×4 system, and there are rumors on the sprinter forums that may be happening in 2021. The rumor is predicated on some planned “retooling” that will make 4x4s unavailable for a few months. Seems plausible.
Question, any realistic good option to convert Mercedes Benz Sprinter 2WD to 4WD
Not really. The company Iglhaut does amazing conversions but they are insanely expensive. They start with a 2wd Sprinter, as none of the 4×4 Sprinter hardware is usable (Iglhaut’s words), and the vehicle is shipped to Germany and back for the conversion. https://www.treadmagazine.com/features/iglhaut-allrad-sprinter/
I think we will see more conversion options in the US in the future. The stock Mercedes system is lousy, so the bar isn’t very high for creating a better system.
So happy to come across this article and all the comments. I have a Subaru Cross Trek and a 1970 VW Westfalia Popup. I’m looking to upgrade from my Westy to a Sprinter so I can go further faster and more reliably, have heat and ac, and potentially to get 4×4. You’ve given me a lot to think about. Really appreciate the time you spent explaining the pluses and minuses. I generally use the Subaru when I want to get squirrelly in the back country, so I’m leaning towards the 2WD Diesel which would give me better mileage for the long trips in the winter months following the sun. Do you think you would buy new or would you look for a used model? I have owned the Bus for 20 years and I’m the 3rd owner. I know how important having a good owner is to maintaining these vehicles. I’m leaning towards a new from dealer to have warranty and longest life expectancy, but I’d appreciate your thoughts. Is there a best year/model Sprinter for some reason? All the best! Robato
Hi Robato, the van is my first-ever new vehicle. I bought new for several reasons–Sprinters retain their value very well, especially now that everyone wants one due to the pandemic. I also had trouble finding one that was in sort of condition I was looking for.
If you tend to keep your vehicles a long time, I think buying new makes a lot of sense. I plan to keep mine for a very long time, and maintain it as such.
Honestly the 2019+ VS30 4×4 Sprinters are having some real issues. Check out sprinter-source.com for info on that. The 4x4s use parts outsourced from an outside company and the systems are known for not going into 4wd when you need it and randomly going in when you don’t want it. Worse yet it seems like the 4wd actuator has issues and it gets itself in a mode where the vehicle won’t go into any gear and it must be towed. You can do your own research on the forums, but I wouldn’t touch the 4×4. I talk to Sprinter owners nearly every day and I’ve gotten to the point where I now ask the 4×4 owners if they’ve had problems and the majority have.
I’m quite partial to the 2014-2016 Sprinters with the 2.1 4 cylinder diesel. They use the excellent 7-speed transmission–the V6 Sprinters of the same year used the archaic 5-speed auto. All the new VS30 diesel Sprinters have the 7-speed. Be on the lookout because in 2021 the 2.1 4 cylinder diesel is returning to the lineup. That’s what I would set my sights on. -Ken
Thank you a thorough and unbiased review of both systems. Greatly appreciated.
Basicly this article has nothing to say except that you got paid by Ford or Quigley etc to make this article. First of all letś focus on one thing – we want tuner version or OEM easy to repair version Second thing – comfort and safety developed thru 25 years of experience and big brains in Germany or mods which come from different available trucks just to be 4×4. Third obviously you may get the Iglhaut for better performance. Fourth the Quigley test Transit vs Sprinter is a joke and faulty, how can anyone compare any two cars in offroad when one has road tyres like Sprinter and second has All Terrain Tyres? Is the Quiqley system so bad that they must cheat on? Another thing is that the AWD system which Transit is offered with Stock is a joke, in Europe it is called the worst 4×4 van of all times (as theygot it before US market). Also there is a crutial thing which people don’t do when buying the Sprinter 4×4 van – THEY DO NOT READ instructions and than believe in the super popular tuning markets “knowledge” offering them modifications which lead to their destruction – mainly people who brake, vibrate or clank anyting on the vans have some crazydouble shock suspensions, lift kits and well oversized tyres. Stock 4×4 sytem in Sprinter isn’t really a superior unit and it should not be this way as this big vans are not Toyota’s Jeeps and never were meant to be. As a campervan with very high roof and easy rollover possibility this system was designed to be a compromise which many people dont understand at all. I have to be negative on this article as it is not constructive at all plus using the cheat movie from Quiqley already shows in which direction it goes – Paid Directive Advertisment
Wow, paid by Quigley, that’s a good one. I provided links to multi-page discussions on Sprinter forums to back-up what I’ve shared. I correspond with Sprinter owners on a daily basis, have lots of friends with these vans, and all their experiences exactly corroborate with what is written here and backed by similar discussions on online forums such as sprinter-source. I have a Sprinter and love it. But the 4×4 system has completely inexcusable problems. 4×4 production is ceasing in early 2021 as the system is reportedly being redesigned. We can all benefit from modernization and a redesign of a system that has known issues.
On a trip with another 4×4 Sprinter owner, we encountered a situation where the van actually performed better in 2wd than in 4wd. On an incline where one side of the road was dirt/mud and the other was snow and ice, I went up first and had no trouble in 2WD. The friend in the 4×4 followed and had significant trouble in 4WD…the van came to a complete stop two times while it was clamping brakes and “trying to figure it out.” He did eventually make it. Then we had him back down and try in 2WD, and surprisingly he made it with far less effort, and the van did not stop at all on the hill. When in 2WD, when a tire slips the system doesn’t have much to figure out–if the left slips it brakes that wheel and sends the power to the right. When in 4×4, with its open differentials, power automatically flows to the wheels with the least traction. Then the ABS system attempts to brake the spinning wheel(s). Then the power flows to the next wheel with the least traction, due to the open diffs. So the system is continually braking different wheels as the power shifts around to the next wheel with the least traction. That’s what we experienced on this day with the 4×4. Inexcusable that the van would perform better in 2WD than 4WD.
The take-away isn’t that 2WD is better than 4WD. It’s that the system lacks a modern center differential that either has locking capability or is able to transfer torque to the axle with the most traction. Sprinter does the opposite. There are situations where it struggles when it shouldn’t. I look forward to Mercedes coming up with a better system.
Transit awd system in the USA is completely different than in Europe. You can’t compare the two.
I owned a 144 RWD for a year, and drove it through winter. Weights in the back, brand new winter tires. Let me make it simple for you: If you go anywhere in snow, don’t even think about getting an RWD. The van was fairly stable on flats, but the moment there was a tiny incline, I had to stop and put chains on. Fast forward, I now own a 170 4×4. Same tires, no weight in the back, only partially built out. I drove this machine through a admittedly mild California winter, but we had a few blizzards that I had no problem cruising through. The same tiny inclines that I got hopelessly stuck with with the RWD, I cruised up with ease on the 4×4.
No noise. No problem. Yeah, the 4×4 is sometimes a bit finicky to engage, but frankly, when I’m in the mountains, I put the 4×4 in and leave it in until I get back to flat land. And I’m personally glad that it has permanent drive on all 4 wheels.
I don’t doubt that there could be better technology options for Mercedes vans. Maybe they will eventually come out with a 4matic system similar to their modern SUVs where torque can shift around instead of brakes put on like it is with the current 4×4. But if you want a Sprinter (design, brand, resell value, …), and you drive through snow, there really is no alternative to the 4×4. I’m sorry to have to say this, but articles like this have caused me doubt and go the RWD route initially. I put a lot of money into the van to build it out, only to cut my losses eventually and having to sell the vehicle because it was really not suitable for me at all. I didn’t do any offroading, but even on dirt roads, the 4×4 was so helpful. The wheels of the RWD were spinning before, and I had no problem getting up that hill with the 4×4.
Having also now spent significant time on the Sprinter Forum, and making friends with other Sprinter people, I also think the alleged concerns about the 4×4 drive expressed on the forum are completely overblown. Yes, some people have issues. But the people I talk to are very excited about their vehicle.
If you feel a Transit is the way to go, then don’t let me stop you. I personally don’t like the design and the fact that it doesn’t have a Diesel option. I test drove one, and it drove nicely, but around 14mpg on the smaller engine was not what I had in mind. It’s quite possible that the AWD technology is more advanced, but curious enough, all I see out there are Sprinters.
The current system works okay in the snow. It struggles when you put it in a situation where tires have unequal traction. The open (non-locking) center differential can’t cope, and the van gets stuck. As stated in this article, traveling with 4x4s we’ve seen these traction limitations come up time and time again, in places where it shouldn’t struggle. It shouldn’t be this way, no other 4×4 system in a modern vehicle has a completely open center differential. But in equal traction situation like snow driving it does okay.
Ken,
You have really put together a wonderful website – thank you for all your hard work. It has been a fantastic and really useful resource for every DIY van builder and your analysis of the pros and cons of the current 4×4 system is spot on!
After reading your March 24th update, I was really excited to hear the MB will finally provide a real factory solution to the Sprinter and hopefully at a slightly lower price point. FINALLY and we can probably thank Ford for that! However, if MB can now sell every 4×4 they make with an 8K+ markup, I doubt that MB would pass up even more profit margin that a factory system will give them. They do have all the RD to recoup after all, but fingers crossed…
I currently have a 2015 2wd and really hate having to chain up in CA… so I am in the market for a new MB 4×4 van for those snowy ski trips but have been waiting for a change to what is clearly an expensive and compromised “third party” add on. At that cost it should have come with a center locking diff option from Oberaigner that we know is available in Europe, or even at the very least a limited slip rear diff that works in conjunction with the traction control. OHV (Off Highway Vans) are apparently working on a limited slip (according to their website), at what will probably cost over 3K I would guess.
In my opinion, MB probably did not want to spend the RD funds on developing an inhouse 4-matic type system without not really knowing what the demand was going to be for these vehicles. They chose the simplest and cheapest solution for their internal business case- a plug and play, off the shelf solution from a third party. Things have probably changed now with demand/profit margins being what they are and now the TRANSIT. Again and this is my opinion, the current system is really only intended as a mild solution to a snowy winter’s day challenge, a 33/67 split will give you a more confident inspiring feeling in slippery conditions when you are moving, but it is obviously challenged from a standstill – even in low range- without a center locking diff. The monster MB van 4×4 conversions we all are seeing are really cool and great to look at and these aftermarket suspension outfitters are making a fortune… but let’s face it, that is not what MB intended. Iglhaut Allrad is the solution for that ($$$)…
Since reading your post, I have been trying to find more information on the internet regarding the new 4×4 system you described, unfortunately, I have come up empty. Do you have any links/press releases, etc. you can share?
Thanks again.
Hi Olivier, thanks for the comment. I agree with everything you stated. Having owned all 4×4 vehicles for the past 20 years it was difficult for me to buy a 2WD. But the experiences my friends have had with theirs left them not recommending them, and now that we travel together I’ve seen how poorly it performs. I look forward to the more modern system. Here are a few links…most are from outside of the country but we are apparently getting the same system in the U.S., although timing is a bit more unclear. https://www.trucksales.com.au/editorial/details/new-mercedes-benz-sprinter-for-2021-128015/. https://www.whitehorsetrucks.com.au/blog/new-mercedes-benz-sprinter-for-2021/2536/. https://outbacktravelaustralia.com.au/buyers-guide-heavy-duty/mercedes-benz-sprinter-4×4/
Ken, I have a 2018 4X4, has 39,000 miles on it. Without going too much into the story, my Sprinter has been a maintenance nightmare. In the 31,000 miles I have owned it, Mercedes has done somewhere around $20,000 in warranty work. Living in Durango, I have to either go to Denver or Las Vegas. I have gone to ABQ, which is closest, and another long story, but suffice it to say I would not let them work on a Vespa, horrible dealer.
The reason for this email, however, is your knowledge of 4X4 systems. Among the many issues I have has with this van, part has been with the 4X4 system. First, the front differential was not mounted correctly at the factory and would ‘slap’ against the subframe when you applied or removed power (driveline lash). That was two months for ABQ and 24 hours (3 trips back and forth) of driving for them to figure that out. Along the way, the right CV joint was found to be bad. And now, this week, the left CV joint went bad. To add insult to injury, Mercedes, either Vegas or Denver, cannot replace it until the 2nd half of June. So it will be two vacations I have had to scrape because the van breaks down (last year and on vacation in about a week). Denver is 14 hours roundtrip driving, 20 for Vegas. Out of sheer frustration, I have decided to sell the van. I dealt with MBUSA last year with all the problems, which was about as helpful as dealing with Yugo. Should I mention a CV replacement at the dealer if I had to pay for it, $4,000.00.
Moving on. I am looking at buying a Transit and having Ford build one if it’s possible; supply is an issue. I can either do the new AWD system or possibly do the Quigley. It seems the lift limit is two inches on the AWD, and I assume as well on the Quigley. Considerations so far are ground clearance as compared to the Sprinter. And my Sprinter is a 170, which I would get the longer Transit. However, for about the same length of the van, their wheelbase is shorter, 148″. This means more van behind the axle.
Suppose I boiled this down to a single question for you. If you were to buy a Transit and wanted 4X4, would you go for an AWD lifted 2 inches or the Quigley system? Considering the Quigley is 10K more and whatever the timeframe is (a couple of months?) to get it done on top of all the van build by Ford and the RV van build time as well? And knowing the Quigley will be a more capable system.
A penny (or a beer) for your thoughts,
PS, great 4×4 article
Hi Jim, sorry to hear. Unfortunately it seems to be a pretty common story. I was dead-set on getting a 4×4, it was actually my friends that owned them that told me not to.
To answer your question, I would probably get the AWD Transit. While the Sprinter system was basically an aftermarket third-party add-on that MB installs at the time of assembly, the Ford system was designed by Ford for use in that van. It works really well. If you’re planning serious offroading, like full on rock crawling, the Quigley will be better. This is just my opinion, but the Quigley is going to be somewhat like the Sprinter 4×4 in that it’s aftermarket and integration may not be factory-perfect.
The other option is to wait for the redesigned MB 4Matic. It should be better than the current Sprinter “4×4” in every aspect, especially in reliability. Having 50/50 drive, seeing the engagement problems go away, and here’s the big one…rather than an open center differential that will send power to the axle with the least resistance (the one with the least traction), the new center diff will be intelligent enough to transfer power to the axle with more traction. Due to the latter, the redesigned system will be far less dependent on the brakes (braking the spinning wheels) and thus more proactive than reactive.
I hope that helps, and sorry you’ve had so much trouble with yours. Very disappointing after putting that much work into your build. -Ken
5 yrs ago when I was shopping for a van I had to figure out the real 4×4 situation re: Sprinter vs other options. Your website would have saved me some time; but I fortunately knew enough people with significant experience. Bottom line is that everything you’ve summarized is correct. By the way, the rear shock hangers on the Transit can be easily and cheaply trimmed significantly (over 2.5”) if you have the 2” block lifts on the rear. I have Torsen LSDs front and rear on my converted 4×4 Transit and generally feel comfortable in any offroad situation that a 4×4 full size pickup with 32 or 33” tires can handle.
As a PS to my recent comment—a major disadvantage of the Sprinter is inability to change differential ratios to compensate for upsized tires. While this mod is inexpensive and easy on a 2WD or AM 4WD Transit, I do not know the situation with factory AWD.
Good points on the axle ratios…Ford also has an available factory limited slip.
After fixing the 4×4 issue will Mercedes consider tackling the center dashboard speaker issue?
Ha, good question. I unhooked mine early-on.
I think this should settle this debate. I buy everything that Ken says about the limits of the Sprinter 4×4 system, but this doesn’t look to me like the Transit is any better. In some situations on rollers, it actually didn’t even move whereas the Sprinter managed it just fine. The diagonal test shows how how the Transit sits as it is really not designed to be used in any offroad situation. The answer to the limitations of the current Sprinter 4×4 system is a better Sprinter 4×4 system, an Iglhaut Allrad Sprinter conversion or a Ford Quigley conversion. But it sure doesn’t look like it is a Transit AWD. I, for my part, am super-happy with my Sprinter 4×4. My main use of 4×4 is Winter, and it did great there.

Hi Michael,
I think you are seeing a couple of variables. The different modes in modern traction control systems do different things. Normal mode is generally for fuel savings and slippery is designed to allow for wheelspin and it’s helpful in sand, snow and mud where spinning the tires can help clear the tread blocks. HOWEVER, in that first video you posted they completely neglected to run the test in Mud/Ruts mode. This mode provides the most braking at tires being lifted off the ground. It would have been the appropriate setting to use and they skipped it entirely. You can see in the second video you posted they did use it. Why they neglected that mode where it matters most is curious.
Also on the roller test for the Sprinter, note the condition of the roller under the left rear. It seems like that left rear was grabbing on the ramp.
I continue to be unimpressed with the Sprinter system (why I didn’t buy one), as it really struggles in places where it shouldn’t. As you point out, it works fine in snow because the open differentials side to side and at the center doesn’t matter as much when all four wheels have equal traction. That said, I love Sprinter vans and it’s not a bash…this article simply informs people how it differs from traditional 4wd systems.
Hi Ken,
First off – love your blog and YouTube. Great seeing where a 2wd sprinter takes you! I picked up a modestly converted 2016 170WB (6cyc diesel) earlier this year for my family’s adventures (based in Southern California – so SW, Sierras, West coast, etc), and so far, we are loving it. I have been surprised with the capability on my van with KO2s (265/70/16). The wallowing, swaying, and other handling characteristics on this beast are pretty poor IMO ,but I have a stage 2 kit from VC incoming.
I am curious when you are planning trips how you decide if a dirt or “overland” route is too much for your van? I really want to push further into backcountry for dispersed camping and exploration, but I have concerns about getting in over our head on trails. Are there any resources that you use to evaluate routes for the sprinter?
Thanks!
Hi Jonathan, these vans are amazingly capable! As stated in the article, the 9’3″ height has been our limiting factor and most often why we have to turn around. Planning-wise, I will acquaint myself with where the public lands are (USFS and BLM) so I know where it’s possible to stay, but of course I have no indication as to what the road or trail is like. The nice thing about a van is it’s maneuverable enough that, worse case, if I have to back a ways down a trail or turn around due to an obstruction, it’s do-able. Imagine doing that if you were a pickup towing a trailer.
I do carry a tow strap, clevis pin for the towing receiver and traction recovery boards, none of which I’ve had to use so far. If you watch any of our travel videos on YouTube, you know we push our van pretty hard. (See our recent Pacific NW trip video, for example.) Please follow up after you get your VC kit–I’ve never nothing but good things.
The 2023 Dealer Ordering Guide is now out:
https://sprinter-source.com/forums/index.php?threads/110913/
A couple takeaways are:
The AWD version only comes with the “HO” turbodiesel 4-cyl engine that produces 208 HP / 332 lb-ft. This replaces the 6-cyl diesel engine that produced 188 HP / 325 lb-ft.
In addition, MB has eliminated the 4.182 axles on all diesel models; the axle ratio for the 2023 diesels (including the AWD version) is 3.923. Thus, the crawl ratio for the 2023 AWD Sprinter is 5.354 × 3.923 = 21.00 rather than 22.39 as stated in the article.
Interestingly, the 4.182 axle is still available in the gasoline-powered RWD Sprinter. The engine in this model delivers 188 HP / 258 lb-ft. Thus, even though the RWD version is geared lower, its maximum effective torque (5,777 lb-ft) is still less than what is available in the AWD version (6,973 lb-ft). For sake of comparison, the older 4WD Sprinter could produce a maximum effective torque of 7,924 lb-ft.
I am very close to ordering my 2023 AWD Sprinter, but I will admit that I’m a little worried that there may be times when I’ll wish that I had an extra 460 lb-ft (offered by a 4.182 axle) to lift my rig up a steep dirt road.
Thanks for the info. It’s interesting the US Spec is using a different rear axle ratio than Europe. As you stated, that would slightly reduce the crawl ratio, although it’s still better than a NCV3 Sprinter with the low range option. Regarding engines, you mentioned the HO diesel and the 4 cylinder gas. There is also a standard output diesel with more favorable specs than the gas, at 170 hp and 295 ft lbs of torque. (My older 2.1 diesel has 166hp/266 ft lbs and does great.). While the non-HO diesel has slightly less power and torque than the V6 diesel, it also has two more gears in the transmission. Back when I drove the V6/5-speed and the 4 cylinder diesel/7-speed (that I purchased) back-to-back, the diesel 4 felt peppier than the V6, likely due to the extra gears. The twin turbos reduce turbo lag as well.
I didn’t mention the standard-output (SO) diesel engine because I was addressing AWD and axle ratios, and if you’re getting an AWD Sprinter, it will only come with the HO diesel engine. By the way, not to be splitting hairs, but my arithmetic says that using the published 1st-gear ratio (5.354) and axle ratio (3.923) for the AR2 axle, the crawl ratio for a 2500 AWD Sprinter is 21.0, not 21.7.
One last comment for those who are obsessed with crawl ratios: it turns out that there is a new option for 2023 that offers AWD on a 144″ wheelbase, but with a new dual-wheel axle (“AR5”) that has a ratio of 4.727. This will provide a crawl ratio of 5.354 × 4.727 = 25.3, which is greater than the crawl ratio that was available in any of the old 4×4 Sprinters.
Ah okay, I just wanted to make sure you were aware of the three engine options—gas and two versions of the 2.0 diesel. Thanks for the additional information, I am really looking forward to this updated version of the Sprinter van.
I came back on here and saw that you have updated your article. This is a great writeup! I particularly like the photos you share giving a comparison of the undercarriages between the former “4×4” and current AWD Sprinters.
Your original article was very useful to us for at least two reasons: it “pushed us over the edge” to decide on getting a Sprinter vs. a Transit, and 2) it convinced us to wait to order the 2023 AWD Sprinter. While I’ve not even yet sat in the driver’s seat of our new Sprinter, everything I’ve read indicates that the AWD with its HO OM654 diesel engine is far superior to the earlier “4×4” Sprinter (and to the new Transit as well).
We ordered a 2023 AWD Sprinter last August (2022), and the van was delivered to our upfitter in March (2023). In addition to the conversion, the upfitter (Field Van in Fresno, CA, formerly “Sportsmobile West”) will install the Agile Off Road Ride Improvement Package suspension. We’re also putting upgraded wheels and the venerable Goodrich All Terrain T/A KO2 tires on the van. The last thing I’m considering (but haven’t decided on yet) is to have Agile Off Road install ARB’s locking rear differential.
We can hardly wait to get “out there!”
Congrats, that will be a very nice van! The AWD vans have soooo many improvements beyond the far superior AWD system. Some of those include the 9-speed transmission, more power, significantly better fuel economy and much better engine responsiveness with the new 4 cylinder diesel, electric power steering and a few other things. Let us know how it goes! -Ken
I own a 2018 frightliner 4×4 2500 cargo van …33,000 mi. it is the best van i have ever owned … 17.5 mi. on a gallon of diesel . around town.
Thank you for writing and then updating this post! There is/was so much FUD over the new Sprinter drivetrain that it was refreshing to read your assessment that was fact based. It helped a lot in guiding our choices and we are hopefully a couple weeks away from picking up our 2023 AWD 170 from our up fitter (Titan Vans). We did the Van Compass 4.3 upgrade as well as wheels and brakes. Plan on either an air locker (Agile) or e locker (Owl Vans) for the rear diff, not sure which one yet. Have also considered the limited slip diff that Off Road Vans sells.
Glad you found it helpful! I’d love to have the new AWD van–enjoy it!
