Ferrari has officially presented the new Ferrari 599 GTO and even the pics themselves show how performance-oriented it is. Based on the 599 GTB Fiorano, the 599 GTO uses the same six-litre V12 engine but with power up to 670 hp at 8,250 rpm (an increase from 620 hp). While we haven’t seen the 599 GTO get to the magic hp number of 700, dry weight is also down to 1,495 kg for a weight-power ratio of 2.23 kg/hp. Acceleration to 100 km/hr is achieved in 3.35 seconds and top speed is more than 335 km/hr.
To achieve these performance figures, the 599 GTO has composite fibre material and the thickness of the glass used has been reduced. The transmission is lighter and the exhaust system was built using a hydroform process. The 599 GTO aerodynamics are based on those of the 599 XX and have been modified to get downforce of 144 kg at 200 km/hr. The front of the car’s width has been reduced and a new splitter added along with air vents in the bonnet to improve the oil radiator cooling. A new diffuser and rear spoiler have also been added.
The V12 engine has 670 hp and 620 Nm of torque at 6,500 rpm. It complies with Euro 5 norms, which is incredible if you think about the performance. High rev performance has been improved with modifications to the aspiration system and the 599 GTO has an F1, six-speed transmission with shift time of 50 milliseconds. Average fuel consumption measures 17.5 l/100 km and CO2 emissions are 411 g/km.
The 599 GTO’s engine is directly derived from the 599XX unit implementing, however, the necessary modifications for road-going homologation. It thus complies with Euro 5 and LEV 2 standards. The 5999 cc 65-degree V12 engine punches out 670 CV at 8250 rpm with maximum torque of 620 Nm at 6500 rpm and there is a smooth, constant rush of power all the way to the redline with no loss of flexibility even at medium and low revs. This result was obtained by working on the fluid-dynamics and components to reduce internal friction and by adopting, amongst other things, the 599XX’s redesigned crankshaft.
The car also has a racing-type intake system with a new manifold with diffuser-type intake geometry and short inlet tracts designed to improve power delivery at high revs and reduce losses. To maximise volumetric efficiency per cylinder, a connection between the two plenums at the front compensates for variations in the volume. This is how the engineers managed to achieve maximum performance at high engine speeds. The engine sound inside the car is carefully controlled to balance the intake sound with the exhaust, which features a 599XX-derived 6-into-1 manifold.The 599 GTO features the same, lower 60 ms shift times and the possibility to make multiple downshifts as on the 599XX.
