NM2255 on YouTube was recently able to film a selection of incredible-sounding Ferrari 599XX Evolutions at a recent Ferrari Corse Clienti event.
The 599XX now features improved chassis dynamics thanks to an active aerodynamic package integrated with the vehicles’ electronic control systems, and the adoption of new Pirelli tyres. The key to the aero package is the active rear wing design which represents a new aerodynamic concept called ‘opening gap’. The wing features two flaps, with profiles similar to those used in Formula 1, which rotate electronically to adjust the downforce between the front and rear axles in function of vehicle speed and the manoeuvre being effected. The result is better performance in cornering.
The new aerodynamics package for the 599XX also includes a modified front splitter and a new rear diffuser featuring a larger surface area and redesigned fences and foot-plates. Total downforce at 200km/h is boosted to 330kg when the flaps are open and 440kg in the closed configuration.
The adoption of side exhausts allowed the engineers to increase engine power by 20 hp to 750 hp again at 9,000rpm, while maximum torque has been increased to 700Nm. When combined with a final gear ratio that’s slightly shorter to improve acceleration on technical, medium- to high-speed tracks, the result is that the car laps Fiorano in just 1’15″.
