2022 Mercedes-Benz GLS: More Distance for Your Tow

Even with its impressive MPG ratings, the 2022 Mercedes-Benz GLS manages a 7,700-pound towing capacity. This makes long-distance big moves possible. This is achieved through raw steel muscle via the 362 HP turbo inline-6 and the 483 HP biturbo V8 engines.

You’ll find an even easier tow thanks to the standard multimode, height-adjusting AIRMATIC® suspension, and 4MATIC® all-wheel drive. The all-wheel drivetrain allows traveling through weather-conditioned roads a breeze. Rain, snow, sleet, or sand can be better handled with this intelligent system.

Your drive will be smoother than ever thanks to these systems coupled with the 2022 GLS efficiency mileage ratings.
