The Triumph TR6 was introduced in 1969 as a replacement for the TR5/TR250. The TR6 featured similar running gear components and chassis as its predecessor but incorporated new external styling. The updated styling, courtesy of Karmann of Germany, allowed for more cargo capacity in the rear of the vehicle when compared with previous models. The doors and the center section remained unchanged from the TR4 and TR5 models. The interior comfort and drivability of the TR6 made it a highly successful British sports car. It was similar to the TR4 and TR5 with quality trim and a walnut dash.
The TR6 was fitted with a 2498 cc, six-cylinder, inline engine. The European fuel-injected version of the engine was capable of producing around 150 horsepower, while the US carbureted variant produced 104 horsepower. In 1972, the engine was de-tuned to 125 horsepower for the purpose of creating a smoother ride for city driving.
The TR6 used a synchromesh, four-speed gearbox and was fitted with overdrive that worked on third and fourth gear.
Throughout its lifespan, many alterations were performed on the car including interior and exterior styling and mechanical changes. In 1973, for example, the European engine was de-tuned to produce 125 horsepower; the purpose was to make the ride smoother through the use of camshaft alterations. During that same year, an air dam was placed below the bumper.
A detachable hardtop was optional equipment on the TR6. This allowed for driving in all weather conditions. An overdrive transmission was also available as options equipment.
In mid-1976, production of the TR6 ceased. During its production run, over 94,500 examples were produced of which, more than 86,200 units made their way to the US.By Daniel Vaughan | Jun 2005
