The TVR Cerbera Speed 12, originally known as the Project 7/12, is a sports car designed by TVR in 1997. Based on the TVR Cerbera, the vehicle was intended to be both the world's fastest 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 forced TVR executives to abandon its development.
The engine, displacing 7.7 L (469.9 cu in) and having twelve cylinders, was reportedly capable of producing nearly 1,000 hp (746 kW), although an exact measurement was never made. Nonetheless, it was claimed to have a top speed greater than that of the McLaren F1.
