The Ferrari Enzo is a 12-cylinder Ferrari supercar named after the company's founder, Enzo Ferrari. It was built in 2003 using Formula One technology, such as a carbon-fiber body, F1-style sequential shift transmission, and carbon-ceramic brake discs. Also used are technologies not allowed in F1 such as active aerodynamics. After a downforce of 775 kg (1709 lb) is reached at 300 km/h (186 mph) the rear wing is actuated by computer to maintain that downforce.
