The Triumph TR6 was produced from 1969 through 1976 with about 94,619 examples produced with most destined for the United States. This became the Triumph's best selling vehicle in history. It was powered by a 2498 cc straight-six cylinder engine that produced just over 105 horsepower. The steering was by a rack-and-pinion unit.
The interior was rather luxurious with its bucket seats and wooden dashboard. It was a true and refined sports car that continued on the proud and prosperous tradition of the TR series.

The Triumph TR6 was basically 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.
The 2.5-liter twin-carb engine would be used for the TR6 and mated to a four-speed gearbox. The exterior received mild updates courtesy of Karmann of Germany. The rear featured a chopped-off Kamm tail that had adequate space for luggage. The front was longer and the grille was wider. The removable, optional hardtop was updated with a more angular design.
The TR6 remained in production for seven years with few changes along the way. Perhaps the biggest improvement was in 1973, an updated camshaft. This gave the vehicle better low-speed tractability and improved its idle. That same year, an optional Laycock electric overdrive also became available.
During the early 1970s, the US became more safety conscious and strict rules were made for vehicles. To comply, the TR7 gained large, black bumper guards for 1973.
Production of the TR6 continued through mid-1976 when the newly introduced TR7 took over the legendary TR name. It would, however, not generate the enthusiasm or sales as its TR6 sibling.
