The latest one-off model to emerge from Ferrari's Special Projects division has been revealed.
A sole image of the new car, understood to be called SP FXX, appeared online after reputedly being printed a Japanese motoring magazine.
Ferrari has confirmed to Autocar that the car, pictured at a private unveiling, is an official one-off special. Additional pictures or details, however, will not be made available unless the private client decides to release them.
It's believed that the car is based on a standard Ferrari FF, with the most prominent revision being the adoption of a coupé rear end in place of the FF's shooting brake tail.
Production versions of the Ferrari FF are powered by a 651bhp 6.3-litre V12. Power is primarily sent to the rear wheels via a seven-speed dual-clutch transmission, but the front wheels can be driven by an additional gearbox in certain conditions to provide more traction.
The name 'SP FFX' has not been officially confirmed, but the Italian trademark database shows that Ferrari registered SP FFX in October 2013. The 'SP' in the title is believed to refer to 'Special Projects', a Ferrari division responsible for the creation of bespoke cars for private customers.
Recent cars from Special Projects include Eric Clapton's Ferrari SP12 EC, which was created as a homage to the Ferrari 512 BB
Previously, patent images of the as-then unknown Ferrari SP FFX were originally believed to represent the next-gen Ferrari California.
