A British roadster that was in production from 1969 to 1976, the Triumph TR6 continues to attract collectors and hobbyists who love classic sports cars. This model was considered as Triumph's best-seller from its TR range, a proof of the TR6's reliability, durability, excellent road performance, and distinct style. Some also say that the TR6 was one of Triumph's and Leyland Motor's best achievements, attracting plenty of fans in UK and abroad. As a matter of fact, 86,249 out of 94,619 units were exported.
1969-1972: The TR6 replaces the TRS PI
The TR6 was released by Triumph as a replacement for the TR5 PI, a petrol injection roadster that produced a lot of torque. The TR6's bodywork looked similar to that of the TR5, but its back and front ends were more square-ish. The TR6 was also built with a Kamm tail, a feature commonly found on 1970s cars and on most Triumph models. This roadster was equipped with an inline six-cylinder engine. However, the original engine didn't meet US emission standards, so TR6 units sold in the US were equipped with a tamer twin-carb engine that produced 104 horsepower.
Also included in its standard features is a four-speed manual transmission. An overdrive was an optional feature that attracted many buyers because it allows for more aggressive driving, making the TR6 the perfect sports car when driving fast along open motorways. The TR6 was also equipped with a rack-and-pinion steering, an independent rear suspension, 15-inch wheels, bucket seats, and a floor and trunk with pile carpet. For reliable braking performance, the TR6 featured rear drum brakes and front disc brakes. Its construction was mainly old-fashioned since the frame and body were bolted together. Despite this, the TR6 was known for its reliability and durability.
1973-1976: Upgrades and changes
Throughout its production years, the TR6 underwent only a few minor changes. In the early 1970s, the camshaft was reprofiled to improve tractability when driving at low speeds and provide a smoother idle. The Laycock electric overdrive, which was an optional feature, was also upgraded. US models released from 1973 to 1974 were equipped with black bumper guards. The addition of the bumper guards was in accordance to the five-mph impact standards mandated by the US government.
In 1976, the Triumph TR6 was discontinued to make way for its successor, the TR7. Despite its discontinuation and certain design issues, the TR6 is a favorite among classic car club members and hobbyists who fell in love with the TR6's unmistakable classic vibe, reliable engine, and durable components. Because there continues to be a significant number of Triumph TR6 owners, parts are still readily available, and there are numerous clubs and groups that cater to those who are interested in the preservation, restoration, and upkeep of TR6 units.
