The third-generation 2024 Mercedes-Benz GLS offers a benchmark of luxury in the SUV segment. Two engine options are available: a 362-hp turbocharged 3.0-liter inline-six for the GLS450 variant, and a 483-hp twin-turbo 4.0-liter V8 for the GLS580. Both engines use a nine-speed automatic transmission and come with standard 4MATIC all-wheel drive. This model year sees Mercedes' continued commitment to the combination of luxury and tech, offering a 12.3-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility as well as a MBUX voice assistant. On the safety front, the GLS offers standard automated emergency braking with pedestrian detection, a standard lane-departure warning with lane-keeping assist, and available adaptive cruise control with semi-autonomous driving mode. The GLS truly combines performance power and luxurious comfort wrapped in a sleek design.
