The Alfa Romeo 8C was originally a range of Alfa Romeo road, race and sports cars of the 1930s. In 2004 Alfa Romeo revived the 8C name for a V8-engined concept car. The 8C designates 8 cylinders, and originally a straight 8-cylinder engine. The 8C was Alfa Romeo's primary racing engine from its introduction in 1931 to its retirement in 1939.
Alfa Romeo prepared and entered a single 8C 2900B, chassis number 412033, for the 1938 Le Mans. The car featured a streamlined coupé body built by Carrozzeria Touring. This was the only time the coupé was raced. It now resides at the Alfa Romeo museum, which runs it at events.
