Rank 6. Ferrari Enzo
The Enzo Ferrari is a 12-cylinder mid-engine berlinetta named after the company's founder, Enzo Ferrari. It is currently one of the most powerful naturally aspirated production car in the world. It was built in 2003 using Formula One technology, such as a carbon-fibre body, F1-style sequential shift transmission, and carbon-ceramic brake discs. Also used are technologies not allowed in F1 such as active aerodynamics and traction control. 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.
