Specifically, compared to the FXX-K, the Evo version has a downforce coefficient increased by 23 percent, which translates into increased cornering acceleration and stability.
Compared to a LaFerrari approved for roadside use, the FXX-K Evo has a 75 percent higher aerodynamic pressure. That means 640 kg at 200 km/h and even over 830 kg when the car reaches the top speed. To get a clearer idea, a Lotus Elise Sprint weighs 830 kg.
The biggest role in achieving this aerodynamic pressure is its fixed rear aileron, which was designed to complement the retractable rear aileron, which is also available on the LaFerrari and FXX-K.
The extensive modifications made by this aileron to the general aerodynamics of the car have forced adaptations for the front and floor of the car. The new appendices and cuts that we see on the front spoiler are the result of GT experience, where the rules introduced in 2016 allow extensive study of the interaction between the vertical and horizontal elements used to optimize aerodynamics.
Last but not least, the Ferrari FXX-K Evo was subjected to 5,000 kilometers of tests during its design, and another 15,000 kilometers for later verification of reliability.
These tests are absolutely necessary because the FXX-K Evo, with a V12 engine, 1,050 hp and a torque of 900 Nm, has to withstand the demands during the Ferrari XX series during the 2018-2019 season.
Nine events will be performed on the circuit.
