As the result of the Enzo, Ferrari has decided to use some of the technology developed for it in a small-scale program to get more feedback from certain customers for use in future car design as well as their racing program. The core of this program is the Ferrari FXX. It is loosely based on the Enzo's design with a highly-tuned 6.3 litre version of the Enzo's engine putting out roughly 800 PS (590 kW; 790 hp). The gearbox is new as well as the tires (custom-designed for this car by Bridgestone) and the brakes (developed by Brembo). In addition, the car is fitted with extensive data-recording and telemetry systems to allow Ferrari to record the car's behavior. This information will be used by Ferrari to develop their future sports cars.
Like the Enzo, the car was sold to specially selected existing clients of Ferrari only. The initial price was €1.3 million. Unlike the Enzo, the clients did not take delivery of the car themselves. Rather, it is maintained by Ferrari and available for the client's use on various circuits as arranged by Ferrari and also during private track sessions. The car is not expected to be street-legal or suitable for road use.
The Ferrari FXX program will continue until 2008/2009 with the Ferrari FXX Evoluźione. The car will continue to be improved under the Evolution kit, which will continually adjust specifics to create more power, change gearing, and remove drag. The 6262 cc V12 engine will be pushing out 860 PS (630 kW; 850 hp) at 9500 rpm. There will be gearbox changes so that shift time will be reduced to 60 milliseconds per shift, a reduction of 20 milliseconds. The car will also undergo aerodynamic changes and improvements to the traction control system. Its top speed is 227 miles per hour (365 km/h).
