Our spy photographers have caught an early development mule for the Ferrari 599 successor.

While the car is wearing a modified 599 GTO body, the production vehicle will look nothing like the prototype you see here. Instead, the mule was created to test the car's aluminum monocoque chassis which is reportedly derived from the Ferrari FF.

Previous reports suggest the car - dubbed the F152 - will use a 6.3-liter V12 engine with approximately 700 hp (522 kW / 710 PS). It will send power to the rear wheels through a seven-speed dual-clutch transmission and an electronically locking rear differential.

The 599 successor is expected to be launched in late 2012 or early 2013.
