The Mercedes Sprinter 170 extended is the flagship of the Sprinter passenger lineup: the 170-inch wheelbase paired with an extended rear body. Mercedes builds it for operators who need maximum interior volume without moving up to a bus platform, and it remains the most common chassis for 15-passenger shuttles and large luxury conversions.
It drives like the rest of the Sprinter family — car-style controls, no CDL, quiet diesel cruising — but it carries a group and their luggage at the same time, which shorter Sprinters simply cannot do.
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.
Key specifications
- 170-inch wheelbase with extended rear overhang
- Roughly 24 feet overall length
- High-roof option with about 6'3" of interior standing height
- 2500 and 3500 chassis ratings available
- Turbo-diesel and gas engine options depending on model year
Seating configurations
In factory passenger trim, the 170 extended seats up to 15 across four rows behind the cab. In conversion trim, builders typically install 7 to 12 captain's chairs and use the remaining length for a rear luggage bay, a lounge, or a partition.
Cargo and luggage
Even with a full 15-seat layout, the extended overhang leaves usable space behind the last row — not a full airport bay, but enough for carry-ons. Drop to 12 seats and you get a true luggage compartment. For maximum bags with maximum seats, add a tow hitch at booking and pull a cargo trailer.
Who should book it
- Airport shuttle runs with checked luggage
- Wedding and event groups of 12 to 15
- Sports teams with equipment
- Corporate groups needing a rear luggage partition
- Any group where a shorter Sprinter runs out of trunk
