The Mercedes-Benz GL-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.
From 2016 with the release of the facelifted second generation model, the GL-Class was renamed to GLS-Class as per the revised nomenclature adopted by Mercedes. Under this scheme, SUVs use the base name "GL", followed by the model's placement in Mercedes-Benz hierarchy. The "G" is for geländewagen (German for off-road vehicle) and alludes the long-running G-Class. This is followed by the letter "L" that acts as a linkage with the letter "S", the SUV equivalent to the S-Class.
The GLS is offered in both, petrol and diesel engine formats mated to a 9G-TRONIC automatic transmission.
