About the 2021 Mercedes-Benz Maybach GLS
1st generation, first U.S. model year; based on the third-generation X167 GLS platform
Mercedes-Benz positioned the Maybach GLS as S-Class-style comfort in a full-size SUV. Its core purpose is quiet, spacious, rear-passenger-focused travel, with a high seating position, strong V8 performance, advanced suspension, extensive cabin insulation, and luxury seating. It differs from the regular three-row GLS by using only two seating rows and prioritizing the ride, space, climate control, and technology experienced by rear occupants.
Mercedes-Benz positioned the Maybach GLS as an SUV with the quiet, rear-passenger-focused experience of a top luxury sedan. The GLS 600 4MATIC combines a 550-hp twin-turbo V8 and AWD with road-scanning active suspension, reclining and massaging rear seats, four-zone climate control, and dual 12.3-inch front displays.
