The Mercedes-Benz GLS Class is a full size luxury SUV produced by Mercedes-Benz since 2006. It is a three-row, seven-passenger vehicle positioned above the GLE-Class, and is the flagship of the Mercedes-Benz SUV line. The third generation model debuted at the 2019 New York International Auto Show. The engine options at the launch are 3.0-litre turbo I6 (GLS 450 4MATIC) and 4.0-litre twin-turbo V8 (GLS 580 4MATIC), both petrol with EQ Boost electric motors, and 2.9-litre twin-turbo diesel I6 in two different outputs (GLS 350 d 4MATIC and GLS 400 d 4MATIC). A GLS 600 Maybach model was released in late 2019. The wheelbase is 2.3 inches longer and nearly an inch wider. It will use the same architecture as the latest GLE with MBUX and dual 12.3-inch screens as well as E-Active Body Control and car-to-X communication. The exterior has also been redesigned with sleeker headlamps and taillamps.
