Ferrari FXX

Essentially an evolution of the Enzo, the FXX shares some components with the Enzo, but significant portions are exclusive to the FXX.

The FXX's engine is based on the Enzo's but has been expanded to 6,262 cc (from 5,988 cc), and output has been boosted from 660PS, as seen in the Enzo, to 800PS (588kW) @ 8,500 rpm.

The gearbox incorporates the latest developments from Ferrari's F1 program and has a shift time under 100 ms. The brake pads are upgraded compared to those on the Enzo. It does, however, retain the ceramic discs found on the Enzo.

The tires on the FXX are 19 in (483 mm) slicks custom-developed for the car.

As with the Enzo, the seat and pedal configuration are custom fit to the user's exact measurements.

The FXX features a comprehensive data-monitoring and telemetry that not only allows the driver to improve performance, but also provides Ferrari technicians with valuable data to improve the FXX and future road-going Ferraris.

Ferrari has built 31 of these cars, and they have all been sold to preselected past Ferrari customers, including Ferrari's F1 World Champion driver, Michael Schumacher, which is black and number 30 in the line. One car was not sold and is kept by Ferrari. These few customers will not only own a Ferrari FXX, but also participate in further testing and brand development. As the vehicle is not street-legal, owners have the option of storing the car at Ferrari's facilities. As part of the FXX program, the car is maintained by the Ferrari factory. The purpose of this particular program is to allow Ferrari's top customers exclusive access to its most up-to-date technology and to use their input to help develop future models. The FXX costs 1.3 million euros out of the production line, which makes it the most expensive production car to date.
