The integration between aerodynamics and design has allowed significant improvements in aerodynamic efficiency compared to the F430 by increasing the overall downforce whilst maintaining the same drag coefficient. This development was mainly carried out in the Ferrari Wind Tunnel on a 1:3 scale modular models.
A extensive number of configurations were tested and the configuration which was finally chosen was optimised right down to the smallest detail during track tests.
The efficiency of the new rear diffuser has been increased by the revised profile of the rear lip spoiler on the engine compartment cover and by the air ducts that channel air from the rear wheel arch to the rear bumper, creating a washing effect of the overpressure in the wheel arches ("Base Bleed" patent, developed by Ferrari in the FXX project).
The new lower sills allow a more even pressure distribution underneath the car, thereby generating an increase downforce which is evenly distributed between the front and rear. In this configuration, the shape of 430 Scuderia has an increase in vertical downforce, from 75 kg at 150 km/h, to more than 300 kg at maximum speed.
