Ferrari has revealed a new Evo pack for its flagship track-only FXX-K hypercar, creating the FXX-K Evo.
Essentially a pack that improves aerodynamics and reduces weight on the FXX-K, which in turn is based on the LaFerrari, the Evo now produces 830kg total downforce at the car’s top speed - an improvement of 23% on the standard FXX and 75% over the LaFerrari; 640kg of this is generated at 124mph – close to that of a GT3 championship car.
Extensive revisions across the exterior include tweaked front and rear bumpers for better airflow, with 10% of the downforce improvement attributed to an additional intake in front of the front wheels, and flicks with a vertical turning vane in the front bumper. This front-end improvement is inspired by Ferrari’s GT efforts. The front brake air intakes have also been redesigned.
A further 30% of the extra downforce over the FXX-K is attributed to vortex generators on the undertray.
At the rear, a fixed wing is now fitted, which has been developed to work symbiotically with the active rear spoiler. Although not a new item, the spoiler’s software has been tweaked for maximum benefit with the wing.
