HWA is responsible for managing the AMG Mercedes team in the Deutsche Tourenwagen Masters (DTM). HWA AG was founded in 1999, and takes its name from Hans-Werner Aufrecht, who established AMG in 1967. Towards the end of 1998 Aufrecht sold a majority interest in AMG to DaimlerChrysler AG. As part of the process, the motor racing department and parts of the customised vehicles construction business were spun off and transferred to HWA AG.
HWA AG develops and builds the DTM racing cars and engines used by the HWA Team, and customer teams also competing in the DTM, such as Persson Motorsport and Mücke Motorsport. They also develop and build engines for Formula Three racing cars, based on Mercedes-Benz production engines.
