Brabus GmbH (stylized in uppercase) is a German high-performance automotive aftermarket tuning company founded in 1977 in Bottrop (Ruhr area).

Brabus GmbH was registered in 1977 in West Germany with Buschmann's friend Klaus Brackmann to satisfy German law requiring a company to be established with at least two people.

[2] Brabus's primary focus is to achieve maximum car performance through the increase of horsepower and speed.

Brabus also offers cosmetic modifications including low profile spoilers, body kits, carbon fiber splitters, and multi-piece alloy wheels.

[3] The company also provides improvements to the interior from custom upholstery, gauges, shift knobs, pedals, and trim to various electronics such as wider LCD screens for the Maybach.

[6] The company has built special editions of Mercedes-Benz, Maybach, Rolls-Royce, Porsche, and Smart vehicles.

The Brabus K8 performance kit for the SL model (SL55) includes modifications to the supercharger incorporating a custom vibration damper and pulley, high-performance metal catalysts, and an auxiliary circulation pump with an opposing radiator.

Designed on the base of the Fortwo Brabus, this limited edition example is powered by a 55kW 3-cylinder turbocharged engine although all of the upgraded hardware is from the 60kW motor with a different tune.
