Ferrari 333 SP

The Ferrari 333 SP is a sports prototype race car designed and constructed by Dallara and Michelotto to IMSAs World Sports Car regulations. Designed by Mauro Rioli, Giampaolo Dallara and Tony Southgate among others, the 333 SP heralded Ferraris return to top-level sports car racing following a 20-year absence. The car was powered by a 4.0L F130E V12, a derivative of the Tipo 036 V12 used in the 641, Ferraris 1990 Formula One car; this engine produced 641 horsepower (later versions had engines in different states of tune) and was mated to a 5-speed sequential. A highly successful race car, the car won 56 of the 144 races it entered and was last seen competing in 2003. 40 chassis were produced. The casting was modified in 2006, now featuring four slits in the base and a separate plastic rollbar insert.
