The new XX program car, presented for 2009, was based on the 599 GTB and had an impressive number of modifications to make it a true track car. Particularly noteworthy were the two fans placed in the bonnet which created a depression which glued the car to the ground up to 249 km/h, before the spoilers had their effect. The 599XX was the first road car to break the 7-minute mark on the Nurburgring circuit. The 599XX had a 5999cc V12 engine, with a power of 730hp for a maximum speed of 315km/h. 44 examples were built, before the introduction, in 2011, of the even more extreme Evo version.
