An evolution of the Enzo, in essence, the FXX shares some components with the original 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 cc (6.3 L; 382.1 cu in) from 5,998 cc (6.0 L; 366.0 cu in). Output has been boosted from the Enzo’s 670 PS (492.8 kW; 660.8 hp), to 820 PS (603 kW; 809 hp) at 8,500 rpm. The gearbox incorporates the latest developments from Ferrari’s F1 program and has a shift time of under 100 ms. The brake pads were also upgraded from the Enzo. It does, however, retain the Carbon fibre-reinforced Silicon Carbide (C/SiC) ceramic composite discs found on the Enzo. The tires are custom-developed 19 inch slicks. The FXX features 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.
