BRABUS GmbH is a German high-performance automotive aftermarket tuning company founded in 1977 in Bottrop (Ruhr area). Brabus specializes in Mercedes-Benz, Smart and Maybach vehicles. Brabus is the largest Mercedes-Benz tuner after Mercedes-AMG, which has been a Daimler AG subsidiary since the 1990s.

The company began with Bodo Buschmann wanting to customize his cars, but discovered most existing customizers could not grasp his vision or meet his requirements, so he decided to start his own brand. After Buschmann had decided to start his own brand, was originally registered in 1977 at Germany with Buschmann's friend Klaus Brackmann because German law required a company must be established with at least two people. Following the company's foundation, Brackmann did not show interests in modifying vehicles or running a business, so he sold his company shares to Buschmann for 100 euros.
