Power and Performance

There are two trims in the 2026 Mercedes-Benz GLS SUV lineup, beginning with the Mercedes-Benz GLS 450 4MATIC® SUV. A turbocharged 3.0-liter inline-six engine powers the base trim, and it delivers 375 horsepower and 369 lb-ft of torque. With that amount of power, this model can reach 60 miles per hour from a standstill in just 5.8 seconds.

For a bit more power, the Mercedes-Benz GLS 580 4MATIC® SUV relies on a twin-turbocharged 4.0-liter V8 engine that delivers 510 horsepower and 538 lb-ft of torque, enabling it to accelerate from 0-60 in a swift 4.7 seconds. Like the six-cylinder engine, the V8 powerplant pairs with a nine-speed automatic transmission and 4MATIC® all-wheel drive.

Towing and Cargo

While new Mercedes-Benz SUVs are made for luxury, they're also surprising workhorses. With the appropriate equipment, the 2026 Mercedes-Benz GLS SUV can tow an astonishing 7,700 lbs. If you fold the seven-passenger SUV's second and third rows, the vehicle has a generous 84.7 cubic feet of cargo room.
