There’s no better way to mark the end of production for the most extreme Ferrari 599 ever built then to give it a kickass special edition, and Ferrari is doing just that with the 599XX Evolution. The new Evolution package boasts of aerodynamic advancements, as well as a boost in power, and will be available to clients participating in the track-based research and development program for the 2012-2013 seasons.The new 599XX Evolution features improved chassis dynamics thanks to an active aerodynamic package integrated with the vehicles’ electronic control systems and the adoption of new Pirelli tires. The new aero package uses an active rear wing that 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 maneuver being effected.The most impressive feature, however, is the addition of an extra 50 HP for the 599XX’s 6.3L V12 engine. This addition brings the 599XX’s total power up to 750 HP at 7000 rpm and 516 lb-ft of torque. Helping the engine along is a weight reduction of 77 lbs compared to the standard model.
