The Ferrari 599 GTO is the road-going version of the 599XX track-only supercar.
On 8 April 2010, Ferrari announced official details of the 599 GTO (for Gran Turismo Omologato). The car was a road-legal version of the 599XX track day car and at the time Ferrari claimed that the 599 GTO was their fastest ever road car, able to lap the Fiorano test circuit in 1 minute 24 seconds, one second faster than the Enzo Ferrari. Its engine generated a power output of 670 PS (493 kW; 661 hp) at 8,250 rpm and 620 N⋅m (457 lb⋅ft) of torque at 6,500 rpm. The car has the multiple shift program for the gearbox from the 599XX along with the exhaust system. Ferrari claimed that the 599 GTO could accelerate from 0–100 km/h (0–62 mph) in under 3.3 seconds and has a top speed of over 335 km/h (208 mph). At 1,605 kg (3,538 lb), the 599 GTO weighs almost 100 kg (220 lb) less than the standard GTB. Production was limited to 599 cars. Of these, approximately 125 were produced for the United States market. Ferrari has produced only two other models that used the GTO designation: the 1962 250 GTO and the 1984 288 GTO with the third being the 599 GTO. Unlike the previous GTOs however, the 599 GTO was not designed for homologation in any racing series.
