Ferrari FXX

Ferrari FXX is an evolution of the supercar Ferrari Enzo.

The Ferrari FXX is a high-performance track-only developmental prototype built by Italian automobile manufacturer Ferrari. The FXX is based on the street-legal flagship Enzo Ferrari. Production of the FXX began in 2005.
Limited to 30 cars worldwide.

The Ferrari FXX is the fruit of Ferrari’s know-how in building special limited-series sports cars combined with, of course, its racing experience. 

The FXX uses some technology demonstrated on the Enzo Ferrari and combines it with new developments from Ferrari and its suppliers. However, the car is only a part of the overall FXX program. Customers pay GB£2 million, but are only allowed to drive the car on special track days which are approved by Ferrari. After they drive the car, the owners are entitled to be debriefed by Ferrari on the car's performance. Ferrari's sister company Maserati, has developed a similar car, the MC12 Corsa for this purpose with the only difference being that the owners can keep the car in their custody. The FXX on the other hand, may be stored by owners wherever they please. The caveat behind the FXX is only that Ferrari technicians must look over the car "before the car hits the track in any event or private testing session."

The FXX, an evolution of the Enzo in essence, shares some components with the flagship car, but numerous significant developments are unique to the FXX.

The FXX's engine is based on Enzo's, but displacement has been increased to 6,262.45 cc (6.3 L; 382.2 cu in) from 5,998 cc (6.0 L; 366.0 cu in). Power output has been raised from the Enzo's 660 PS (485 kW; 651 hp) at 7,800 rpm, to 800 PS (588 kW; 789 hp) at 8,500 rpm.

There exists 30 Ferrari FXX supercars worldwide.

Ferrari has built 30 cars in total, adding one special edition to the 29 cars that were originally planned. The original 29 cars have all been sold to pre-selected past Ferrari customers. The 30th car was retained by Ferrari S.p.A. and presented to Ferrari's F1 World Champion driver, Michael Schumacher, along other an Enzo Ferrari when he retired from Formula One racing at the end of 2006 as a token of appreciation for his achievements.[4][5] Schumacher's FXX differs from others in having black paintwork without stripes, having red trimmed wheels, matte rather than chrome exhaust tips, and his personal logo stitched on the racing seats.
