2026 Mercedes-Benz GLS-Class GLS 450

The GLS-Class is Mercedes-Benz's full-size three-row SUV, slotting above the GLE and below the Maybach flagship. It competes with the BMW X7, Audi Q7, and Range Rover, offering a blend of luxury and utility. The GLS drives with composed confidence, its air suspension smoothing out most surfaces while keeping body roll in check. Inside, the cabin is spacious and opulent, with three rows of seating and a large MBUX touchscreen dominating the dash. With all three rows up, cargo space is modest, but folding the rear seats opens up a generous load area. The GLS 450 is where the three-row luxury SUV experience starts, with the mild-hybrid six-cylinder instead of the V8 you get in the GLS 580. Its 3.0L I6 pairs with a mild-hybrid system and the nine-speed automatic, delivering 375 horsepower and 369 lb-ft of torque to all four wheels. The standard air suspension makes the ride exceptionally smooth, and you can option a six-seat layout with second-row captain's chairs.
