A year of CFD simulations and wind tunnel tests have given rise to an aerodynamic design that can achieve aerodynamic load values very similar to those seen on GT3 and GTE championship cars. The result is an increase in the lateral acceleration that can be reached in corners, as well as improved stability and greater driving pleasure.
The increase in downforce is equal to 23% compared to the previous version, and 75% compared to the road model from which the car is derived. This value can reach 640 kg at 200 km/h, and more than 830 kg when the car is travelling at top speed. The force exerted by a fixed bi-plane wing on the rear axle has increased the aerodynamic load level. The wing works in perfect synergy with the active aerodynamics of the rear spoiler, and the pressure fields created by the two load generation systems support and amplify one another.
The new analysis and programming of the logic and range of movement of the mobile spoiler ensure excellent results in terms of aerodynamic load and resistance.
Two lateral fins and a central fin support the rear bi-plane wing. The central fin uses vertical drift, increasing the stability of the car at low yaw angles, as well as supporting the three delta vortex generators.
The vortex generators serve to “clean” the flow field that affects the wing, removing the force exerted by the wake of the radiators that emit the air on the bonnet. In addition, these also generate a degree of downwash in the flow, which increases the aerodynamic load capacity of the bi-plane wing. The result is a 10% increase in the downforce generated by the rear system.
The display to the right of the driver, which enables the images captured by the rear camera to be viewed, measures 6.5”, larger than before. In addition, this screen also displays all the data pertaining to the new telemetry system, so the driver can view the performance and vehicle status parameters directly. The driver can select from the various screen views available and check the status of the KERS system, as well as keeping track of the times achieved by the car.
