BMW used the CSL name for the first time back in 1972 when it unveiled the 3.0CSL - a special version of the Six CS (E9) developed to race the European Touring Car Championship. In 2004, that named was used once again, but this time on a road-going M3 CSL (Coupé Sport Leichtbau).
The CSL version was about 240 pounds lighter than a regular M3, thanks to the use of many weight-saving technologies inspired by Formula 1 cars. The model also boasted 17 extra horses under the hood than a standard M3 and thanks to its front-engine, rear-drive layout and the SMG-II gearbox, it delivered the purest driving dynamics of any BMW of the time.
The M3 CSL was limited to only 1,400 units and was offered only in two exterior colors: Silver Grey Metallic and Black Sapphire Metallic. The model never made it to the U.S. market and in the British market it was considered a very expensive car, as it was about £20,000 ($32,000 at the current exchange rates) more expensive than a standard M3.
