The legendary BMW 3.0 CSL made a rare auto show appearance today at the 2015 Detroit Auto Show.
Some history via wikipedia:
In 1973, Toine Hezemans won the European Touring Car Championship in a 3.0CSL and co-drove a 3.0CSL with Dieter Quester to a class victory at Le Mans. Hezemans and Quester had driven to second place at the 1973 German Touring Car Grand Prix at Nürburgring, being beaten only by Chris Amon and Hans-Joachim Stuck in another 3.0CSL.
3.0 CSLs would win the European Touring Car Championship again in every year from 1975 to 1979.
Initially using the same engine as the 3.0CS, the 3.0CSL was given a very small increase in displacement to 3,003 cc (183.3 cu in) by increasing the engine bore by one quarter of a millimetre. This was done in August 1972 to allow the CSL to be raced in the "over three litre" racing category, allowing for some increase in displacement in the racing cars. In 1973, the engine in the 3.0CSL was given another, more substantial increase in displacement to 3,153 cc (192.4 cu in) by increasing the stroke to 84 mm (3.3 in). This final version of the 3.0CSL was homologated in July 1973 along with an aerodynamic package including a large air dam, short fins running along the front fenders, a spoiler above and behind the trailing edge of the roof, and a tall rear wing. The rear wings were not installed at the factory, but were left in the boot for installation after purchase. This was done because the wings were illegal for use on German roads. The full aero package earned the racing CSLs the nickname "Batmobile"
Enjoy.
