The Triumph TR6 (1968–76) is a sports car built by British Triumph Motor Company between 1968 and 1976. It was the best-seller of the TR range when production ended, a record subsequently surpassed by the TR7. Of the 91,850 TR6s produced, 83,480 were exported; only 8,370 were sold in the UK.
The bodywork was generally similar to the TR4/TR5, but the front and back ends were squared off, reportedly as a result of a consultancy contract involving Karmann.
All TR6s were powered by Triumph's 2.5-litre straight-6, with the same Lucas mechanical fuel-injection as the TR5 for the United Kingdom and global markets, and carburetted for the United States, as had been the US-only TR250. The TR6PI (petrol-injection) system helped the home-market TR6 produce 150 bhp (110 kW) (145 hp DIN) at model introduction.
The TR6 featured a four-speed manual transmission. An optional electrically switched overdrive operated on second, third, and fourth gears on early models and third and fourth on later ones. Construction was traditional frame. Other features included semi-trailing arm independent rear suspension, rack and pinion steering, 15-inch (380 mm) wheels and tyres, pile carpet on floors and trunk/boot, bucket seats, and full instrumentation. Brakes were discs at the front and drums at the rear. A factory steel hardtop was optional, requiring two people to deploy. The dashboard was walnut veneer. Other factory options included a rear anti-roll bar and a limited-slip differential.
The UK version TR6PI could accelerate from zero to 60 mph (97 km/h) in 8.2 seconds and had a top speed of 120 mph (190 km/h) according to Autocar magazine.
As of 2016, approximately 3400 licensed and 1300 SORN TR6s were registered with the DVLA in the UK.
