"170 extended" refers to the Sprinter's 170-inch wheelbase with the extended rear body — the longest passenger Sprinter available. The extra length sits almost entirely behind the rear axle, which is why this configuration is the one to book when you need both a high seat count and real luggage space.
This is the body used for 15-passenger shuttles, airport transfer fleets, and larger executive conversions that need a rear luggage bay plus lounge seating.
Everything here is booked through My Van Rentals — the largest van rental platform in the United States, so you get one quote, one contract, and one support line no matter which city you're in.
170 extended versus standard 170
A standard 170-inch Sprinter and a 170 extended share the same wheelbase, but the extended version adds roughly 15 inches of body behind the rear wheels. That overhang is pure cargo volume — the difference between a couple of duffels and a genuine airport-run luggage bay.
What the extra length gets you
- Meaningful rear luggage bay even with the last row installed
- Room for a fourth passenger row in shuttle builds
- Space for a rear lounge or luggage partition in conversions
- Better ride quality on the highway from the long wheelbase
What to know before you drive one
- Roughly 24 feet long — plan parking accordingly
- Still no CDL required for passenger builds
- Longer turning circle than a 144-inch Sprinter
- High-roof versions may not clear some parking garages
- Backup camera standard on most model years
When a shorter Sprinter is the better call
If your group is eight or fewer and you are driving in a dense city, a 144-inch Sprinter parks far more easily and costs less per day. Book the 170 extended when seat count or luggage volume is the constraint.
Sprinter van 170 extended — frequently asked questions
How long is a Sprinter 170 extended?

How many passengers does it seat?
Up to 15 in shuttle trim, or 7 to 12 in executive conversions with a large rear luggage bay.
Do I need a special license?
No. Passenger Sprinters, including 170 extended builds, only require a standard driver's license.
Will it fit in a parking garage?
Length is usually manageable, but high-roof builds exceed many garage height limits. Plan for surface parking.
