FXX-K is Ferrari’s research and development program centering around a laboratory car based on Maranello’s first hybrid. The K is a reference to the KERS kinetic energy recovery system used to maximize performance on the track. Unfettered by certification requirements and regulations, the FXX-K will never be used in competition and was developed to be completely uncompromising. It incorporates an array of technological innovations that will guarantee an unprecedented driving experience to the exclusive group of Client-Test-drivers with which Ferrari will roll out a special test program over the next two years.
The FXX-K punches out a total of 1050 hp of which 860 are delivered by the V12 internal combustion engine and 190 hp by the electric motor, with overall maximum torque in excess of 900 Nm. The 6262 cm3 V12 has been optimized too for track use as has the HY-KERS system. The latter was evolved with performance in mind and is controlled using a specific Manettino with 4 positions: Qualify, (maximum performance within a limited number of laps); Long Run (consistent performance); Manual Boost (instant maximum torque delivery); Fast Charge (rapid recharge of batteries).
A focus on delivering maximum efficiency at every stage of every track lap has resulted in extensive but integrated work on the entire car body in terms of both active and passive aerodynamics. The FXX-K also applies downforce generation and balancing concepts introduced and developed in the GT category of the WEC in which Ferrari succeeded for three consecutive years. The result is downforce of 540 kg at 200 km/h.
FXX-K vehicle dynamics
Vehicle dynamics are improved by the adoption of Pirelli slicks complete with sensors that monitor longitudinal, lateral and radial acceleration, as well as temperature and pressure. This ensures an accurate analysis of the interaction between the tire and track surface, providing vital data to enable the traction control system to guarantee maximum performance.
