Ferrari SP12 EPC

Back in the summer of 2010, Eric Clapton stopped by the Ferrari factory in Maranello, Italy, with one request: could they build him a 458 Italia with a V12? Nearly two years later, this is what resulted.

Reportedly called the SP12 EPC (bearing the initials of the famous rock guitarist), the one-off product of the Ferrari Special Projects division first surfaced with a few photos the other day, but now we've got video footage of the car moving under its own power away from a London dealership – presumably en route for delivery at the multiple Grammy Award winner's home.

With styling cues borrowed from the 512 BB – an early mid-engined Ferrari that was never officially homologated for sale in the United States – the SP12 EPC is said to be based on the 458 Italia. Which isn't a bad place to start. The big question on everyone's mind, however, is what resides under the hood? Did Ferrari manage to shoehorn in the twelve-pot as hoped, or did it stick with the 4.5-liter V8 in the donor car? Hard to say, but sources point towards the latter.
