The Ferrari 333 SP is a sports prototype race car that was built by Italian race car manufacturer Dallara and later Michelotto to compete in the World Sports Car championship for Ferrari. Unveiled at the end of 1993, at the behest of amateur racer Giampiero Moretti (owner of the MOMO auto parts business), the 333 SP marked Ferrari's official return to sports car racing after a 20-year absence. The car was built to compete in the IMSA's new WSC class, which replaced the previous GTP cars.
