2024 Mercedes-Benz GLS: What's New, Specs & Features
Last updated August 4, 2026
The 2024 Mercedes-Benz GLS receives a mid-cycle refresh, led by updated exterior styling, newer cabin technology, and more power for both mainstream engines. Its three-row layout, standard all-wheel drive, and air suspension carry over.
About the 2024 Mercedes-Benz GLS
3rd generation (2020-present), mid-cycle refresh year
Mercedes-Benz positions the GLS as its full-size luxury SUV for families who want real three-row space without giving up a premium cabin. The brand’s message is essentially “three rows, all in first class,” pairing smooth turbo power, standard air suspension, premium audio, and big-screen tech with a cabin that can comfortably handle daily family duty or long trips. Against rivals, its identity centers on a softer, more polished luxury feel rather than truck-like toughness.
The GLS 450 remains the core model, pairing a 375-hp turbocharged six-cylinder engine with air suspension, dual 12.3-inch displays, wireless smartphone integration, and Burmester audio. The GLS 580 adds a 510-hp twin-turbo V8, leather upholstery, massaging front seats, five-zone climate control, and more advanced driving assistance.

“M-B GLS 580 is a great vehicle. So far it is reliable, handles great, and very comfortable on long trips. My only complaint so far is that it is not as quiet as I thought it would be with the acoustic package.”
“Not to buy the Mercedes GLS 450 we're having transmission problems the vehicle accelerates we almost hit someone. I just don't like this vehicle.”
