“The GLS63 is not just transportation, it's incredibly powerful and just plain fun to drive, even if just to and from work. On long trips, drive time is a bonus and makes every trip enjoyable. It feels like you're driving a sports car, not an SUV. You'll get so many compliments while driving this SUV. Just walking out the garage puts a smile on my face when I look at it.”
2022 Mercedes-Benz GLS: What's New, Specs & Features
Last updated August 4, 2026
The 2022 Mercedes-Benz GLS has no major redesign or mechanical changes. Its main update is a standard enhanced alarm system with parking damage detection across the lineup.
About the 2022 Mercedes-Benz GLS
3rd generation GLS (X167), launched for 2020; 2022 is the third model year, before the 2024 refresh.
Mercedes-Benz positions the GLS as its full-size three-row SUV for families who want first-class comfort without giving up space or everyday usability. Mercedes’ own messaging centers on “Three rows, all in first class,” with emphasis on turbo-hybrid power, AIRMATIC suspension, and a rich cabin experience. Against rivals, the GLS leans on a quiet ride, upscale interior materials, strong straight-line power, and a genuinely usable third row rather than truck-like toughness.
The GLS 450 is the comfort-focused core model, with a mild-hybrid six-cylinder engine, all-wheel drive, air suspension, three-row seating, and twin 12.3-inch displays. The GLS 580 adds a twin-turbo V8 mild-hybrid engine, leather upholstery, massaging front seats, five-zone climate control, and soft-close doors.

“Even though this is an expensive vehicle you will not be sorry. This car is amazing- very safe, so many features, and luxurious to drive.”
“Does not handle well. Like driving a large van. Like the features and seating but a disappointment for handling. The premium sound system is not worth it. Had Bose in my Audi it was better”
