Updated October 8, 2026

Seats: 6–7[2]
Power: 375–603 hp[1]
Towing: 7,700 lbs[2]
Drive: All-wheel drive[1]

The 2027 GLS is the Mercedes-Benz SUV with three rows of seats in every version. The second row comes as a three-person power bench or as captain's chairs with a walk-through to the third row. The current lineup on mbusa.com has three models: the six-cylinder GLS 450, the V8 GLS 580 and the AMG GLS 63, all with all-wheel drive. It suits families who use all three rows, buyers who tow, and anyone who wants rear-seat comfort to be the priority rather than an afterthought.
