Unfettered by homologation 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 the Prancing Horse will roll out a special test programme over two years. At the Mugello 2017 Finali Mondiali the new EVO kit was introduced. The program will go on for another two years with the new FXX K Evo car. 

The FXX-K punches out a total of 1050 cv of which 860 are delivered by the V12 ICE and 190 cv by the electric motor, with overall maximum torque in excess of  900 Nm. The  6262 cm3 V12 has been optimised too for track use as has the HY-KERS system. The latter was evolved with pure 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). 

The FXX-K Evo’s downforce coefficient has been improved by 23% on the previous version, which is the equivalent of a 75% increase on the road car from which it is derived. Downforce of 640 kg is generated at 200 km/h, and exceeds 830 kg at the car’s red-line speed. The FXX-K Evo’s downforce level is boosted by a twin-profile fixed wing on the tail. This new addition was developed to work in seamless synergy with the active rear spoiler. In fact, the pressure fields developed by the two downforce-generating systems support and amplify each other.  To guarantee both excellent downforce and drag results, the mobile spoiler’s control logics and range of movement were also meticulously reviewed and reprogrammed.

Vehicle dynamics are further 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 tyre and track surface, providing even more vital data to enable the traction control system to guarantee maximum performance.
