And it does seem legit, indeed, as it is currently waiting for the 2015 Frankfurt Motor Show in order to see daylight for the first time in an official environment.
A report indicating that Ferrari is planning a hotter version of the F12 Berlinetta has been released a few days back. The model in question will be called the F12 GTO and it will basically be the successor of the 599 GTO. The two images posted below are from a private configurator and have leaked on the web ahead of its public debut which is still a few months away, in September, during the 2015 Frankfurt Motor Show.
Rumor has it that only 650 units of the new Ferrari F12 GTO will be produced and this should shed some 100 kg from its total weight. This, along with the more powerful engine, will be translated into a better 0 to 100 km/h sprint and probably a higher top speed. Don’t act too surprised if Ferrari will decide to upgrade the brakes and the chassis too, in order to make it more maneuverable. The current F12 Berlinetta is making use of a 6.3 liter V12 naturally aspirated unit, rated at 730 HP (544 kW) and 690 Nm (509 lb-ft). This needs just 3.1 seconds in order to reach 100 km/h (62 mph) and it can go all the way up to 365 km/h (227 mph). The F12 GTO is believed to produce up to 800 HP. Additional details on it remain unknown at this time.
