1974 Triumph TR6

The Triumph TR6 was introduced in 1969 as a replacement for the TR5/TR250 and would remain in production through 1976. The TR6 featured similar running gear components and chassis as its predecessor but incorporated new external styling courtesy of Michelotti (It is believed that Karmann offered styling assistance to the project). The updated styling 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 was comfortable, and the 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 but took the well-appointed formula a step further with pile carpeting, plush-looking bucket seats, and a full complement of instrumentation.

The Triumph TR6 was built on a compact 88-inch wheelbase with body-on-frame construction and powered by a robust 2498 cc (2.5-liter) inline six-cylinder engine. The European fuel-injected version of the engine produced around 150 horsepower, while the US carbureted variant produced 104 horsepower. In 1972, the engine was de-tuned to 125 horsepower to create a smoother ride for city driving. The underslung independent rear axle, first introduced on the TR4A, provided a comfortable ride. The transmission was a synchromesh, four-speed unit with an overdrive that worked on third and fourth gear. Weighing less than 2,500 lbs. without its optional insulated steel hardtop, the TR6 had a sporty persona with equally impressive performance, capable of reaching 107 mph.

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 optional 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.

The Triumph TR6 was an updated version of the TR5, which itself was basically a TR4A with a beefy pushrod six-cylinder engine in place of a four. The TR5 had a new fuel-injection (PI for Petrol Injection) system, which did not fully comply with U.S. emission standards. So in place of the TR5 PI version with its 150 horsepower, the US received a twin-carburetor TR250 model, which produced 104 horsepower.....
