The fastest production sportscar Ferrari produce, the 599 GTB, will soon have a successor.

The F620 GT in classic will have its world premier in March at the 2012 Geneva AutoSalon.

It is called internally F152 as we previously reported but at launch it will publicly wear the official model number F620.

It will be powered by a V12 engine with a displacement of 6.3 litres, and a range topping 710 hp and expected to do the 0-60 sprint in around 3.5 seconds. This will be sent to the rear wheels with the same 7 speed dual clutch gearbox as in the 458 albeit tweaked for the additional power output.

The styling will be a fusion of the 458 Italia and the FF following the current range design cues.
