The Ferrari FXX program will continue until 2008/2009. The car will continue to be improved under the Evolution kit, which will continually adjust specifics to create more power, change gearing, and lower the aerodynamic drag. The V12 engine will generate 860 PS (630 kW; 850 hp) at 9500 rpm which boosts the top speed to 387 km/h (240 mph), and the acceleration to 0–100 km/h in 2.5 seconds. There will be gearbox changes so that shift time will be reduced to 60 milliseconds per shift, a reduction of 40 milliseconds. The car will also undergo aerodynamic changes and improvements to the traction control system.. The FXX program also gave rise to the 599XX program in late 2009. The 599XX, a racing version of the 599 GTB borrows technology which was developed from the FXX. The 599XX is faster than the Enzo and is able to lap the Fiorano circut 1.2 second faster than the Enzo.
