The GLS is Mercedes-Benz's largest SUV model, a full-sizer with three rows of seating. This is a crossover interpretation of the
S-Class sedan, so all occupants are treated to a comfortable, high-quality environment. No GLS variant wants for power, but AMG-tuned versions are the performance leaders, and boast surprisingly agile handling. A 2020 update brought more high-tech features and an advanced air suspension to improve comfort and off-road capability.
