The TVR Tuscan V8 was a front engine, rear wheel drive sports car built by TVR from 1967 to 1971.

History

The car was made available in both a V8 and a V6 built in the company's Blackpool, England factory with a total of 174 cars built between the two available engine formats. It replaced the Griffith 400 on the US market and the TVR Griffith 200 in Europe. 

In 1967, the first Tuscans were made available with only the V8 motor. The motor was a 4727cc Ford V8 with cast iron block and head, similar to the motor available in early Ford Mustangs with compression ratio of 11. The motor was equipped with a Ford 4-barrel carburettor, made 271 hp, and was capable of propelling the car to a top speed of 155 mph. Stopping power came from disc brakes in the front and drums in the rear the chassis type as integral with tubular backbone structure, the distribution of weight at 52% to the front axle, and 48% at rear axle. From the 1970s an updated wide body version was also built. The front suspension was independent, wishbones, coil springs and anti-roll bar with telescopic dampers at the rear also independent, wishbones, 4 coil springs and 4 telescopic dampers.

Production of the V8 models dwindled after the release of the V6, and was discontinued altogether in 1970. In total, 73 cars were sold by TVR with a V8.
