Ferrari 599 GTB Fiorano Testing New KERS System?

A prototype model of the Ferrari 599 covered in black cladding has been snagged on film during testing at the Fiorano circuit. We're not entirely sure if it's a test mule for a replacement of the 599 or an updated version of the current model, possibly featuring Ferrari's upcoming KERS energy-recovery system which was first shown on the Geneva Salon HY-KERS hybrid concept.

In any case, the vented hood and the styling of the bumpers point towards a prototype based on the 670-horsepower 599 GTO, which was introduced into the range this past April, with some minor changes such as the California-esque LED headlamps.
