Carlsson Autotechnik GmbH is a German car tuning manufacturer specializing in Mercedes-Benz cars. The company was founded by brothers Rolf and Andreas Hartge in 1989 and is located at Gut Wiesenhof, a manor house near the town of Merzig in Southwest Germany. The company name honors Swedish rally driver Ingvar Carlsson, who, together with Björn Waldegard and Walter Röhrl, made motor-racing history in the Mercedes Rally Team.
Carlsson GmbH is best known for their tuned Mercedes models, but they also provided tuning kits for Citroën, Honda and Toyota. The spectrum of services they offer ranges from mild body modifications and chassis tuning, via increased engine performance and interior-design modifications. The company is most popular for its range of alloy wheels.
Carlsson took the first step up to becoming a coachbuilder by introducing the Carlsson C25, a heavily tuned and rebodied Mercedes SL600. The C25 will be introduced at the 2010 Geneva Auto Salon.
