The Acadia has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLS doesn’t offer a cap-less fueling system.

The GMC Acadia’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GLS only has 5 wheel lugs per wheel.

The Acadia is available in both front-wheel drive and four-wheel drive configurations. The GLS doesn’t offer a two-wheel drive configuration.
