The monstrous TVR 7/12: the powerful and lightweight 800-hp prototype of the 1990s

The TVR 7/12 prototype was first unveiled at the Birmingham Motorshow in 1996 and attracted much attention for its 7730 cc displacement and 12 cylinders in the V-engine.

Initially based on an FIA GT1 class race car with a modest 660 hp, the road car would have weighed about 1,000 kg, but without the limiters, power would have been increased to 800 hp.

It had a 6-speed manual transmission and a specially built clutch, and was powered by a TVR AJP6 straight-6 engine with a steel engine block usually unusual for a car of its type.

The record board and the TVR 7/12
The TVR 7/12 has never participated in official racing, yet it has been talked about for its impressive performance.
