The TVR Cerbera Speed 12, originally known as the Project 7/12, was a high performance concept car designed by TVR in 1997. Based in part on then-current TVR hardware, the vehicle was intended to be both the world's highest performance road car and the basis for a GT1 class endurance racer. However, problems during its development, changing GT1 class regulations and the eventual decision that it was simply incapable of being used as a road car ended the idea, forcing TVR executives to abandon its development.
