Ferrari has unveiled its latest XX program car, the FXX-K Evo, which will be available as an extremely limited edition, and as an upgrade kit for existing cars, for the 2018/19 season of nine events running from March to October.

The XX program started in 2005 with the FXX, a highly-modified track-only adaptation of the Enzo Ferrari. The program involves selling a low number of an exclusive supercar to select customers who drive them only on track days approved by Ferrari, and then engage in debrief sessions on the car’s performance, in effect contributing to future Ferrari road-going products.

The cars (to date, the FXX, 599 XX and now the FXX-K Evo) employ concepts from all of Ferrari’s racing ventures — Formula 1, GT3, GTE and the Ferrari Challenge. There are no versions homologated for road use and is not available for any racing series. The cars are maintained by the factory and used only in the XX program.

The prime directive for the FXX-K Evo was weight reduction (despite the inclusion of a fixed rear wing), adopting innovative carbon fibre component designs from Formula 1. An evolved aero package has been developed over the past year to improve it by 23% over the previous car, and ensure downforce equal to those of the GT3 and GTE cars (640 kg of downforce generated at 200 km/h and in excess of 830 kg at red-line vehicle speed), and aid in superior lateral acceleration and stability.

The twin-profile fixed wing works in tandem with an active rear spoiler to amplify downforce and improve drag. It features two side fins and a central vertical fin that improves stability and supports the work of the three triangular vortex generators that negate the wake of hot air coming out of the engine and striking the wing; they also help improve rear downforce by 10%.

The rear bumpers have also been modified with larger by-pass vent from the rear wheel arches to channel the wake from the wheels and allow the diffusers to improve rear downforce by 5%.

With all the improvements in rear downforce, designers had to also modify the front to ensure a balanced development of downforce. Channels beneath the headlights feature a couple of flicks provide 10% of the overall downforce gain, while vortex generators on the undertray account for another 30% of the overall downforce gained.

Other improvements to performance include redesigned brake ducts, and recalibrated front double wishbone/rear multilink suspension to adapt to the new aerodynamic efficiencies.

The cabin has also been extensively modified, starting with a new steering wheel inspired by Formula 1 (integrating shift paddles and the KERS Manettino control), larger display for the rearview camera and data readouts for car systems and timers.

Power for the FXX-K Evo is supplied by an 848-hp 6.3-litre V-12 in combination with a 140-kW electric motor for a net power output of 1035 hp, controlled by a 7-speed Formula 1 dual clutch transmission.
