Model overview

The Mercedes-Benz GLS-Class, previously Mercedes-Benz GL-Class is a full-size luxury SUV manufactured by Mercedes-Benz as 2006. It is a three-row, seven-passenger car slotted over the GLE-Class and is the flagship of the Mercedes-Benz SUV family.

The GLS shares the identical unibody design with the GLE-Class. Most GLS-Class cars are constructed at the Mercedes factory in Alabama, without a small amount of early 2007 stock cars which were made in Germany. The first-generation model was produced among 2006 and 2012 and was followed in 2012 by the new generation GL-Class.

Of 2016 with the announcement of the facelifted second-generation model, the GL-Class was changed to GLS-Class as per the revised classification used by Mercedes. Following this plan, SUVs use the first name "GL", followed by the model's position in the Mercedes-Benz hierarchy. 

The 2020 Mercedes-Benz GLS-Class is offered in two basic trims: the inline-six (362 hp, 369 lb-ft) powered GLS 450 and the V8-powered (483 horsepower, 516 lb-ft) GLS 580. Both powertrains are matched to a nine-speed transmission and Mercedes' all-wheel-drive system called 4Matic.
