History of the 1969-1976 Triumph TR6
The Triumph TR6 (1968–76) is a sports car built by British Triumph Motor Companybetween 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 TR6 is adored by British sports car fans as the last of the traditional hairy-chested English roadsters. While it’s possible to argue with the precise wording of that statement, the TR6 was certainly antique in many ways when it was introduced in late 1968. A narrow cockpit, separate body and chassis and a bouncy ride courtesy of its rather crude independent rear suspension made it seem in many ways to be little advanced from the TR4 of 1962 or even the TR2 of 1953.
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.
On the plus side, Karmann of Germany had done a masterful job of updating the TR4 body shell while actually changing very little. All TR6s were powered by Triumph's 2.5-litre straight-6, with Lucas mechanical fuel-injection for the United Kingdom and global markets but carburetted for the United States
The U.S. version produced 104 bhp. The TR6PI (petrol-injection) system helped the home-market TR6 produce 150 bhp.
The 2.5 liter straight six, while not a powerhouse in emission controlled twin carburetor form for the U.S. market, had plenty of torque and made some of the best sounds in sports cardom. TR6s are easy to maintain, good-looking, rugged and have easy parts availability. They make an ideal first collector car.<From Wikipedia.org and Hagerty.com>
