The TVR Tuscan V6 was a front engine, rear wheel drive sports car built by TVR from 1969 to 1971.

History

In 1969, TVR would release the Tuscan equipped with a 2994cc OHV Ford Essex V6 motor, which came from Ford's British division (also used in the Ford Zodiac and Ford Capri. The brakes were changed from the V8 model, as only the front used discs, and the rear had drum brakes. The V6 powerplant fitted with a Weber 40 DFA downdraught twin barrel carburettor produced 136 hp, and the car was able to reach speeds of 125 mph.

PERFORMANCE: V6

  • max power (SAE): 147 hp at 4.750 rpm
  • max torque (SAE): 192 1b ft. 26,5 kg m at 3,000 rpm
  • specific power: 49 hp/l
  • power-weight ratio: 13.6 1b; hp. 6.2 kg/hp
  • acceleration: standing 1/4-mile 16 sec, 0-50 mph (0-80 km; h) 5.5 sec
  • fuel consumption: 25 m/ imp gal, 20.8 m US gal. 

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. In the USA, the Tuscan V6 did not meet the exhaust emission regulations there. Only seven of the 101 Tuscan V6s went abroad. Instead of the Essex engine, TVR developed the TVR Vixen 2500 for the North American market based on the Tuscan V6, which was introduced only in 1970 and had an emissions-cleaned and US-approved version of the in-line six-cylinder engine from the Triumph TR6 from the time . 

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.

There was a total of 101 V6 cars produced before the line was stopped altogether to make way for its successor, the TVR Vixen.
