2025 Mercedes-Benz GLS: What's New, Specs & Features
Last updated August 4, 2026
The main change for the 2025 Mercedes-Benz GLS is a standard fingerprint scanner that loads saved driver profiles. Otherwise, this is a quiet carryover year with the same engines, suspension hardware, and three-row layout as 2024.
About the 2025 Mercedes-Benz GLS
3rd generation GLS (X167, 2020-present), second year after the 2024 refresh.
Mercedes-Benz positions the GLS as its large three-row luxury SUV for buyers who want flagship-style comfort without giving up family space. The core message is “Three rows, all in first class,” backed by turbo-hybrid power, standard air suspension, a rich cabin, and real room in the third row. Its appeal versus rivals is the way it blends long-distance comfort, upscale tech, and everyday usefulness in a full-size SUV that still feels polished and easy to live with.
The GLS 450 is the core seven-seat model, pairing a turbocharged six-cylinder engine with air suspension, a 12.3-inch touchscreen, and several driver-assistance features. The GLS 580 adds V8 power and more comfort equipment, including massaging front seats, leather upholstery, five-zone climate control, and soft-close doors.
