The 2027 GLS is suited to buyers comparing three-row passenger space, towing capability, powertrain choices, and technology.

The Mercedes-AMG GLS 63 produces 603 hp while retaining the passenger and towing capability described above. Compared with the prior model year, the 2027 GLS standardizes DIGITAL LIGHT micro-LED headlamps, makes MB.DRIVE ASSIST and MB.DRIVE PARKING ASSIST standard rather than optional, and integrates generative AI into the MBUX Virtual Assistant. These changes increase the amount of listed standard equipment across the lineup for 2027.
