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 frame, engine, running gear, body tub and doors were similar to the Michelotti-styled TR5 (TR250 in the US). The front and rear of the car was restyled by Karmann of Germany, though one source claims the new squared-off Kamm tail design was from an unrelated Michelotti prototype.

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 carbureted 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) (152 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 Michelin asymmetric XAS tires which dramatically improved the handling, 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 finale to the long running TR model line-up, the TR7 didn’t quite live up to all that had gone before, but the penultimate TR model (the TR6) earned itself a most respected place in history. Produced between 1969 and 1976, the majority of TR6s sold for export and were powered by a 2.5-litre straight-six engine, with either twin carburetors or fuel-injection set-up. The front suspension arrangement of wishbones, coil spring and telescopic dampers and IRS by semi-trailing arms, with coil springs and lever dampers at the rear, offered fine handling qualities.
