Sprinter 144 vs 170 - Which one is the better adventure van?

The Mercedes-Benz Sprinter Van has been the go-to option for adventure vans, van life, and just about any other type of outdoor activities for the last decade. It’s a proven model, and there are lots of Sprinter roof racks and interior upgrades for all of the Sprinter options (144”, 170” and 170” extended). Today, we are going to discuss the two most popular options for adventure vans: the 144" High Roof and 170" High Roof models. 

Both the 144" Sprinter and 170" Sprinter wheelbases have their pros and cons, and we are going to do our best to walk you through them with side-by-side comparisons and our own opinions based on experience. We’ve been around these vans for more than a decade, and we’ve owned both the 144” and 170” Sprinter, so we have a lot of time behind the wheel, and inside each of these Sprinter models.

Quick Verdict: Which Sprinter Is Right for You?

Choose the 144" if:

• You want a nimble, parkable van for weekend trips and urban use

• You're building for 1-2 people

• Off-road capability matters - a shorter wheelbase gives you a better breakover

• angle on technical terrain

• Budget is a factor (144s typically cost less to buy and build)
  

Choose the 170" if:

• You need maximum living space (roughly 3.5’ extra length of buildable interior)

• You're building for a family or planning extended van travel

• You want room for a dedicated bathroom, large galley, or rear seating without compromise

• You don't mind tighter parking and wider turns

Choose the 170" EXT if:

• You want the absolute maximum interior space available

• You're building a mobile office, expedition rig, or commercial upfit

• Parking and maneuverability are genuinely not a concern

FVC Take: If you're agonizing over the decision, you probably want the 170. People who need the 144 usually already know. They want something nimble, parkable, and efficient. The 170 is for everyone who wants more space and is willing to trade some maneuverability for it.

Side-by-Side Specs: 144 vs 170 vs 170 EXT

All specs below are based on the 2026 High Roof Sprinter (VS30). Verify final numbers against the Mercedes configurator before purchasing.

Sprinter 144 Overview

The Sprinter 144 is the smallest option in the Sprinter line with a total length of 19' 4" and roughly 10.5 feet of buildable interior space. It's popular among overlanders because it's more nimble, and the shorter wheelbase allows it to perform better on trails and other technical terrain. The smaller square footage compared to the 170" can be a turn off for some people looking for extra space for toys and other gear, but a well-designed 144 build can fit everything two people need.

If the additional space for extra seats, a fixed bed, or a larger galley aren't necessary, then the 144 can be a great option. A Murphy bed system is one of the most space-saving upgrades on a 144 build. It lets you reclaim floor space and you gain extra counter space when the bed is stowed, which makes a real difference in a smaller layout.

Sprinter 170 Overview

The Sprinter 170 is the big brother to the popular 144 chassis. It's longer, it can store more toys (or people), but it's less nimble than the 144. As of this writing, we currently own a 170" Sprinter and love the extra space it provides for surfboards or bikes on trips to the coast, and there's plenty of room to post up and play cards when the weather at the mountain isn't cooperating. Check out the Sprinter 170 dimensions below to see if it will be a better overall choice space-wise.

The 170” is going to give you the most usable space for your interior layout - period. It allows plenty of room for rear seats, a large galley, and you can leave your bed set up all at the same time, making it more ideal for full time van life. The trade-off is that the 170’s extra length can run into tight parking situations.

Sprinter 170 EXT Overview

Most comparison articles skip the 170 EXT, but it's worth covering since it comes up a lot. At 24.15 feet long with 15.5+ feet of buildable interior length, the 170 EXT is the largest Sprinter option available and it's built for a very specific use case.

If you’re building a mobile medical unit, a high-end expedition vehicle, a commercial upfit, or a full mobile office setup, the EXT gives you space that's genuinely in a different category than the standard 170. It's heavier, harder to park, and harder to maneuver. Turning radius stretches to around 43 feet.

Most weekend adventurers and van-lifers don't need a 170 EXT. But if you're considering it, you probably already know you need it. The use cases are narrower, but for the right build, there's nothing else like it.

Drivability: How Does the 144 Handle Compared to the 170?

144 Sprinter: If you are making the jump from driving a smaller car to driving a big vehicle, this is the easiest transition. It drives similar to an F150 (similar wheelbase) or large SUV, but it's a lot taller. If you want a 4x4, you will be giving up Starbucks drive-thrus (sorry coffee fiends, you’ll need to walk inside to get your caffeine fix). Its shorter wheelbase also gives it a better breakover angle and departure angle than the 170, which matters on technical terrain. 

170 Sprinter: In the city is where you'll notice the biggest difference between the 144 and 170. The 170 drives like a bigger rig, and it can be a little tricky to navigate tight city streets, especially when you are just getting used to driving it. That said, most people find they adapt within a day or two behind the wheel. 

170 EXT Sprinter: The extended version takes everything said about the 170 a step further. The turning radius makes tight campgrounds and city streets require extra patience. It's the least nimble of the three, and that's a trade-off most 170 EXT buyers are already aware of going in.

We should mention that both the 144 and 170 Sprinter vans handle well and feel very similar at highway speeds, with the 170 having some extra length to get used to. All are the same height in their respective drivetrain options, so regardless of which wheelbase you choose, you'll want to keep an eye out for low-hanging branches and height-restricted entrances. 

Parking: Where Will You Park Your Sprinter the Majority of the Time?

Parking and parallel parking are another important thing to consider when deciding between the 144 and 170 Sprinters. Are you going to have ample parking space for the larger 170 in your driveway, shop, or city street? We've found that the 144 is much easier to park in an urban setting, and you're less likely to upset your neighbors because the 144 doesn't take up much more space than a normal SUV or truck.

Based on our experience, you can almost always find parking spaces for both, but the 170 can require some extra walking to and from because you'll likely need to park a few blocks away from your destination.

One note on parking garages and drive-throughs: both the 144 and 170 High Roof Sprinters sit over 9 feet tall, which puts them above the clearance limit for most parking garages and drive-through lanes regardless of wheelbase. This applies to both models equally.

Sprinter Van Gas Mileage Comparison

Fuel economy figures changed with the 2023 model year, so it's worth knowing which generation you're buying.

How many MPG does the Sprinter 144 and 170 get? 

The base 2019-2022 Mercedes Sprinter 4x4 vans used either a 3.0-liter V6 turbo diesel or a 2.0-liter four-cylinder gas engine. The V6 diesel was rated around 20 MPG from the factory, with real-world converted van mileage landing in the 14-18 MPG range depending on build weight, terrain, and driving conditions.

2023 and newer Sprinters dropped the V6 diesel and moved to an updated 2.0-liter four-cylinder diesel (in 168 hp or 208 hp configurations), along with a four-cylinder gas option. The new four-cylinder diesel is more efficient than the V6 it replaced. Real-world converted van mileage runs around 15-18 MPG on diesel, with stock (unbuilt) vans doing better. The 2023+ models also switched from a manual 4x4 system to an automatic AWD setup.

For both generations, the 144 and 170 get roughly the same MPG out of the box. The difference shows up once they're fully built out. We've found that larger tires, ladders, and roof racks all impact mileage, which is why we highly recommend our Low Pro Series Roof Racks if you are looking for an aerodynamic rack option. Our rear ladder is also a great way to reduce drag compared to a side ladder option. 

Overall, the 2019+ Sprinter van fuel economy is impressive for being a large 4x4 vehicle. Please note that upgrading your wheels and tires will also impact your gas mileage.

Storage Comparison

The Sprinter 144 has 372.8 cubic feet of cargo space and roughly 10.5 feet of buildable interior length. The smaller square footage means you may need to compromise a little bit to fit all of the amenities you want. We've found that you'll want a bed system that can be stowed away if you also want to run additional seats in the back and have a galley/kitchen setup. Overall, you can easily make the 144 work for 2-4 people, but it can feel cramped if you are spending a lot of time inside the van due to inclement weather.

he Sprinter 170 has 488.1 cubic feet of cargo space and roughly 14 feet of buildable interior length. We've found during our builds that the 170 has plenty of room for a Sprinter bed system, additional rear seats, and a galley. The extra square footage compared to the 144 is pretty noticeable once you start adding all the creature comforts you'll want in your adventure van.The 170 has plenty of room for 2 people, and we've found that it can easily accommodate 4-5 people comfortably with the right interior layout. We recommend going this route if you want to have a full bed, galley, and additional back seats. 

The Sprinter 170 Extended has 530 cubic feet of cargo space and 15.5 feet of buildable interior length. The extra 1.5 feet of length from the 170 may not sound like much, but it really does open up the space and storage options. Large galleys, a fixed bed, and a full wet bath are all doable. You will still want to prioritize your needs accordingly, but the options are more flexible with the extended version.

Here's a more detailed breakdown of what each wheelbase can realistically fit:

Conversion Layout Considerations

What Fits in a 144

With 10.5 feet of buildable length, the 144 layout typically centers on a bed platform with storage and gear space underneath, combined with a kitchen toward the middle or rear. A fixed bed or a convertible dinette works well, while having both permanently set up is a tighter squeeze. A compact wet bath is achievable with careful planning; a full enclosed bathroom is more of a stretch but not impossible. Rear seats are doable but they do affect how your kitchen/living space is used. Every design choice in a 144 has a trade-off, and that's not a bad thing, it just pushes you to be more intentional with the layout.

What Fits in a 170

With 14 feet of buildable length, the 170 opens up significantly. A fixed bed, a full galley, rear seats, a gear garage, and an enclosed bathroom are all achievable in the same build. There's room for a permanent bed and a dinette or rear seats at the same time. The extra 3.5 feet is forgiving in a way the 144 simply isn't. If your layout isn't perfectly optimized, you've still got room to work with. 

In both the 144 and 170, a fixed bed is going to take up a large chunk of your interior space. With a Murphy bed, you can have a comfortable, queen-size bed at night, and reclaim that floor space during the day for cooking, a workspace, loading gear, or just moving around freely. It’s one of the most practical upgrades you can make to either build, and especially worth considering in a 144 where every square inch counts.

Accessories and Fitment by Wheelbase

What's the Same on Both

Most exterior accessories fit both wheelbases identically since the cab and rear door are the same across both platforms. Front bumpers, side ladders, rear ladders, rear door platforms, and tire carriers all mount the same way on a 144 and a 170. Most interior storage and upper cabinet options are also interchangeable.

What's Different: Roof Racks

Roof racks are the most significant fitment difference between the two wheelbases. The 144 uses a 6-crossbar system at approximately 139" long (60 lbs), while the 170 uses an 8-crossbar system at approximately 179" long (76 lbs). The 170 EXT uses its own rack length as well. All three use the same mounting system and accept the same accessories. Decking, solar mounts, crossbar add-ons, and awning brackets all work across every wheelbase. The 170 simply has more roof to work with, which means more surface area for solar panels and gear. Browse Sprinter roof racks.

Frequently Asked Questions

Is a 144 or 170 Sprinter better for van life and adventure travel?

It depends on how you use it. The 144 is a great choice for solo travelers or couples who spend most of their time outdoors and use the van for sleeping and cooking. The 170 is better for those who need more living space, or want a bathroom, a workspace, or room for kids and pets. Both are excellent adventure platforms and, as one of our readers put it: you really can't go wrong with a Sprinter.

How much longer is the 170 Sprinter than the 144, and is it hard to drive?

The 170 van body is about 40 inches (3.33 feet) longer overall, which translates to roughly 3.5 feet of additional buildable interior space. In terms of driveability, the 26-inch wheelbase difference is what you actually feel behind the wheel, noticeably affecting the turning radius. That said, the 170 is easy to adapt to. Most people feel comfortable behind the wheel within a day or two. The biggest adjustment is in tighter spaces like parking lots and campgrounds, where the extra length is more noticeable than it is on the open road.

Can a 170 Sprinter fit in a normal parking spot?

It depends on the lot. A standard spot is 18-20 feet long and the 170 is about 22.8 feet overall, so it can overhang most standard spaces by 3-5 feet. It fits in most open lots but can be tricky in compact lots or tight spaces. The Sprinter high roof vans are also too tall for most parking garages and drive-thrus. 

Is the 144 Sprinter too small?

Not at all. Thousands of people have built highly functional vans on the 144 platform and use them for everything from weekend camping to extended travel. The trade-off compared to the 170 is layout flexibility. You'll typically choose between a fixed bed and a dinette rather than having both, and fitting a full wet bath requires careful and precise planning. That said, a compact wet bath or outdoor shower setup is achievable, and a Murphy bed can make the interior feel significantly more spacious. 

Can you stand up in both the 144 and 170 High Roof?

Yes. Both high-roof models have the same interior standing height: expect about 6’ 4” of standing room once flooring is in. The wheelbase affects interior length, not ceiling height. If you're looking at a standard roof or low roof Sprinter, the interior height drops significantly to around 68 inches. For van builds, the high roof is almost always the right choice.

Does the 170 Sprinter get worse gas mileage than the 144?

Marginally, once fully built out. Both get similar MPG from the factory. A fully built 170 tends to carry more weight, which can push fuel economy toward the lower end of the range. The real-world difference is usually 1-2 MPG, and not enough to be a dealbreaker. For the breakdown on fuel economy by model year, see the fuel economy section above.

Do Flatline Van Co roof racks fit the 144, 170, and 170 Extended?

Yes, but each wheelbase uses a different rack. The Sprinter Low Pro 144 rack has 6 crossbars (approximately 139" long, 60 lbs). The 170 rack has 8 crossbars (approximately 179" long, 76 lbs), and the 170 EXT has 8 crossbars (approximately 184” long, 61lbs). All three use the same mounting system and accept the same accessories, with decking, solar mounts, crossbar add-ons, and awning brackets working across every wheelbase. The Standard and Safari Roof Racks have similar differences for each size as well. Browse all of our Sprinter roof racks here.
