BRABUS manages this extraordinary SUV performance with custom modifications to aerodynamics, suspension and brakes. The front apron of the BRABUS WIDESTAR version was developed in the wind tunnel.

Its large air dams provide radiators and front brakes with ample cooling air. In combination with a carbon-fiber spoiler lip the front apron also minimizes aerodynamic lift on the front axle – a prerequisite for directional stability beyond 300 km/h (186 mph). Favorable aerodynamic properties were also a top priority for the design of the BRABUS WIDESTAR fender flares on front and rear axle. They add five centimeters (two inches) to the width of the GLK.

Custom-tailored rocker panels create a smooth transition between front and rear flares. The rocker panels feature LED lights in their undersides that are activated via the keyless remote or by pulling on a door handle. These lights illuminate the ground next to the SUV for safe entering and exiting the vehicle in the dark.
