2021 Mercedes-Benz GLS towing capacity

The 2021 Mercedes-Benz GLS is published in 2 configurations with a tow rating of 7,700 lb (full-size truck and SUV territory).

The table below lists every trim of the 2021 Mercedes-Benz GLS with the engine, drivetrain, axle ratio, horsepower, torque, GVWR, curb weight, and payload that go with that trim's headline tow rating. Manufacturers often publish more than one tow figure per truck — a conventional bumper-hitch rating, a weight-distributing rating, and a gooseneck or fifth-wheel rating — so the highest number here is the maximum across all hitch classes the source carries for the trim.

Per-trim breakdown

How to interpret the headline tow figure

Tow ratings at this level are normally achievable with a conventional Class II or Class III receiver hitch. Always verify your vehicle has the manufacturer's tow package installed if you intend to tow at the upper end of the rating, and inspect the door-jamb sticker for the actual maximum permitted on your specific configuration.

How this year compares to 2020

The 2020 Mercedes-Benz GLS carried a maximum tow rating of 7,700 lb. The 2021 model carries the same headline figure — manufacturers usually leave the rating alone year-over-year unless there's a powertrain or hitch change. See the 2020 Mercedes-Benz GLS page for the full per-trim breakdown of the prior year.
