Ferrari has issued some updates for the 599XX, making the Italian carmaker's track-based research and development vehicle program based on the road-going 599 GTB Fiorano even more hardcore.
Already the pinnacle of Ferrari road car and Formula 1-derived technology, the 599XX has been updated with features that improve chassis dynamics, thanks to an active aerodynamic package integrated with the vehicles' electronic control systems to go with the new Pirelli tires. In addition, the car is also more powerful than before with an output of 740hp while weighing 35kgs less.
According to Ferrari, the key component to the 599XX's upgraded aero package is its 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 Ferrari's Formula 1, which rotate electronically to adjust the downforce between the front and rear axles depending on the vehicle's speed and the maneuver being performed by the driver. The end result, supposedly, is the car's improved behavior when cornering.
The 599XX's active rear wing operates automatically depending on specific parameters that are integrated with the car's other electronic control systems like the stability control program and the anti-lock brake system. As a result of this integration, all the electronic controls have been suitably recalibrated.
The updated aerodynamics package for the 599XX also includes a modified front splitter and a new rear diffuser, which features a larger surface area and redesigned fences and foot-plates. Total downforce at 200kph is reportedly at 330kg when the flaps are open and 440kg in closed configuration.
Besides increasing the power output to 740hp, the adoption of side exhausts allowed the engineers to also increase the 599XX's torque 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 a lap time of just one minute and 15 seconds on Ferrari’s Fiorano test track.
