The BMW 3.0 CSL, short for Coupé Sport Leichtbau, was developed in the early 1970s that laid the foundation for BMW’s motorsport dominance for touring car competition. Among the most celebrated examples is the 1973 BMW 3.0 CSL “Batmobile,” chassis 2275997, a true factory-built aerodynamic evolution raced in FIA Group 2 specification during the 1973 European Touring Car Championship by legendary drivers Chris Amon and Hans Stuck. Renowned for its dramatic wings and splitters that maximized high-speed stability, this CSL achieved one of its greatest triumphs with an overall victory at the 1973 Nürburgring 6 Hour, helping cement the model’s reputation as the car that propelled BMW to multiple European Touring Car Championship titles and established the enduring legacy of BMW M performance.
