The Mercedes-Benz SLR McLaren is a grand tourer jointly developed by German automotive manufacturer Mercedes-Benz and British automobile manufacturer McLaren Automotive and sold from 2003 to 2010. When the car was developed, Mercedes-Benz owned 40 per cent of the McLaren Group and the car was produced in conjunction between the two companies. The "SLR" name is an abbreviation for "Sport Leicht Rennsport", and was a homage to the Mercedes-Benz 300 SLR which served as the car's inspiration. The car was offered in coupé, roadster and speedster bodystyles, with the latter being a limited edition model.
