This new prototype which is caught in 599 disguise could possibly be the Dino revival. It proves that Ferrari is working on a new supercar, apparently something between recently released California and 599 GTB Fiorano. In that case, it would be a direct competitor to Porsche 911 Turbo and Aston Martin Vantage. In terms of power plants, chances are it uses the same 4.3 liter V8 of California with 450 hp which seems to be enough to take on 911 and Vantage.
