Triumph TR6

The Triumph TR6 (1969–76) was the best-seller of the TR range built by Triumph when production ended in July 1976. This record was then surpassed by the TR7. Of the 94,619 TR6s produced, 86,249 were exported; only 8,370 were sold in the UK.

The bodywork closely resembled that of the previous model, the Triumph TR5, but the front and back ends were squared off, reportedly based on a consultancy contract involving Karmann.

All TR6 sports cars featured inline six-cylinder engines. For the US market the engine was carburetted, as had been the US-only TR250 engine. Like the TR5, the TR6 was fuel-injected for other world markets including the United Kingdom, hence the TR6PI (petrol-injection) designation.

The Lucas mechanical fuel injection system helped the home-market TR6 produce 150 bhp at model introduction. Later the non-US TR6 variant was detuned to 125 bhp (93 kW) in order for it to be easier to drive, while the US variant continued to be carburetted with a mere (but more reliable) 104 hp.
