Power and Performance

You have two engines to choose from in this new Mercedes-Benz model, beginning with the 2027 Mercedes-Benz GLS 450, where an inline six-cylinder engine produces 375 horsepower and 413 lb-ft of torque for confident acceleration at any speed. The 2027 Mercedes-Benz GLS 580 upgrades to a V8 engine that achieves 530 horsepower with 553 lb-ft of torque. Both power plants pair with a nine-speed automatic transmission and 4MATIC® all-wheel drive.

Towing and Cargo

Cargo room behind the third row totals 17.4 cubic feet in the 2027 Mercedes-Benz GLS SUV, and folding the rear seats flat opens that up to 84.7 cubic feet. Properly equipped, your 2027 Mercedes-Benz GLS 450 tows up to 7,700 lbs, enough for the trailer or boat you’ve been wanting to bring along. That mix of passenger room and towing strength keeps this SUV practical well beyond your daily commute.
