The BMW 3.0 CSL, affectionately known as the “Batmobile,” is one of the most iconic cars in the 1970s. Introduced in 1972 as a homologation special for the European Touring Car Championship (ETCC), the 3.0 CSL was a high-performance variant of the BMW E9 coupe. The car was developed by BMW’s motorsport division to establish the brand’s dominance on the racetrack and bolster its reputation as the ”Ultimate Driving Machines”.
The “CSL” in its name stands for Coupé Sport Leichtbau (Coupe Sport Lightweight), reflecting its focus on weight reduction. Engineers employed extensive use of lightweight materials, including aluminum panels, thinner steel, and Perspex windows, to shave off hundreds of kilograms from the standard 3.0 CS. Inside, luxury features were minimized, and soundproofing was removed to prioritize performance.
Under the hood, the 3.0 CSL was powered by a range of inline-six engines, evolving from 3.0 liters to 3.5 liters in later models. By the end of its production, the most powerful versions delivered up to 400 horsepower, paired with upgraded suspension, brakes, and aerodynamics for improved handling at high speeds.
The “Batmobile” nickname emerged from the distinctive aero package added to later models, including a massive rear wing, roof spoiler, and front air dam. These features, initially supplied in the trunk due to German road regulations, dramatically enhanced the car’s track performance.
On the racetrack, the 3.0 CSL became a legend, dominating the ETCC with six championships between 1973 and 1979 and achieving notable success in endurance events like the 24 Hours of Le Mans.
