2023 Mercedes-Benz GLS-Class GLS 450

The GLS is Mercedes' full-size luxury SUV, the one you cross-shop with the BMW X7 and the Range Rover. It's a big SUV that drives smaller than it is, with a composed ride and plenty of power from every engine. Inside, the cabin is genuinely opulent, with three rows of seats that fit adults in the back and a huge cargo area behind the third row. The dual 12.3-inch screens run Mercedes' latest MBUX system, and the standard driver aids include active braking and blind-spot monitoring. Its 3.0L I6 makes 362 horsepower and pairs with a nine-speed automatic and all-wheel drive, returning 20 mpg combined. Standard AIRMATIC air suspension keeps the ride plush over bumps and levels the load automatically when you're hauling gear.
