This latest product from the XX Programme marks a significant evolution since the programme's origin in 2005. As was the case with the Evo versions of the FXX and the 599 XX, the Ferrari FXX-K Evo benefits from an extensive package that applies innovative concepts from the various track categories in which Ferrari competes its cars:  the Formula 1, GT3, GTE and Challenge.

Coming from the racing world and adopting track-specific content, the FXX-K Evo—like all the previous XX cars—is not homologated for road use and will not be used in competition outside its dedicated programme. It is aimed, rather,  at a small, highly-select group of Ferrari clients: supercar enthusiasts who are eager to collaborate with the Prancing Horse technicians in advancing the capabilities of a closed-wheel laboratory car.

Here's an overview of the notable features of this super vehicle:

Lightweightedness

At the development stage, the designers worked on a broad range of aspects of the FXX-K Evo, starting with reducing its overall weight. By drawing on Ferrari’s Formula 1 experience and adopting new carbon-fibre component crafting processes, they succeeded in producing a lighter car than the previous FXX-K despite introducing new elements such as the fixed rear wing.

Better Downforce

The product of over a year of CFD simulations and wind tunnel testing, the FXX-K Evo’s aerodynamics deliver downforce figures very close to those of the cars competing in the  GT3 and GTE championships, all to the advantage of lateral acceleration in cornering, stability and, ultimately, exhilarating driving pleasure.

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 seamlessly with the active rear spoiler. To guarantee both excellent downforce and drag results, the mobile spoiler’s control logics and range of movement were also meticulously reviewed and reprogrammed.

New Vortex Generators

The design of the rear bumpers was modified in the light of new flow structures, affected by the vehicle's vortex generators. The by-pass vent from the rear wheel arch is now larger, hollowing out the volume behind the wheels and resulting in a protected flow to the rear diffuser.

The geometry of the sides of the front bumper has also been  altered by hollowing out the surfaces beneath the headlights, making space for  a couple of flicks divided by a vertical turning vane and an additional intake ahead of the front wheels.

This system guarantees efficient downforce generation (10% of the increase in downforce gained on the FXX-K). It also makes good use of know-how acquired in the GT programmes in which rules introduced in 2016 permitted extensive study of the interaction between horizontal (flicks) and vertical (dive plane) flow management systems, optimising their efficiency.

Boosted Ground Effect

Ground effect was also boosted by the introduction of vortex generators on the undertray. The FXX-K Evo’s upgraded performance demanded new front brake air intakes which are now are more efficient thanks to a complete redesign of the intake itself. Furthermore, the suspension was specifically calibrated to adapt it to the car’s new aerodynamic efficiency figures.

Intelligent Display

The rear video camera screen to the right of the driver has been replaced with a larger 6.5” version. It also now displays data from a new telemetry system with clearer, more direct performance parameter and car status readouts. The driver can check the KERS (kinetic energy recovery system) times being clocked by selecting from the various screen options available.

After undergoing around 5,000 km of development runs and 15,000 km of reliability test-drives, the FXX-K EVO will be a very active protagonist in the XX Programme in the 2018/2019 season, which spans nine track outings in all between the start of March and the end of October.
