The 2027 Mercedes-Benz GLS

The 2027 Mercedes-Benz GLS gives the brand's largest SUV a substantial refresh. This is a thorough facelift rather than a ground-up redesign, with new styling, a reworked cabin, and more powerful engines across the lineup. Here is what is new, what is changing, and what carries over as you shop the GLS at Kunes Mercedes-Benz of Sycamore in Sycamore, Illinois.

The GLS looks and feels more modern for 2027. The front end adopts the latest family look with an updated chrome-framed radiator grille and contour lighting, and the cabin steps up to a pillar-to-pillar MBUX Superscreen paired with the AI-powered MB.OS operating system. Air suspension is standard, higher trims can add E-Active Body Control for an even smoother ride, and a new Executive Rear Seat Package Plus brings added comfort to the second row.

The engines gain meaningful power. The GLS 450 now makes 375 horsepower and 413 pound-feet (an extra 44 pound-feet), and the GLS 580 moves to a new 4.0-liter V8 rated at 530 horsepower and 553 pound-feet (up 20 horsepower and 15 pound-feet). Every GLS pairs all-wheel drive with mild-hybrid assistance. Pricing rises with the added content and varies by source as the lineup settles, with recent listings starting in the mid-$90,000s and climbing well into six figures for AMG. Because final pricing and package details are still firming up, confirm the exact build with the team at Kunes Mercedes-Benz of Sycamore.
