1975 Triumph TR6

The Triumph TR6, although related to the 1950's era TR2, was vastly different from the bare-bones roadsters. Designer Giovanni Michelotti was given the task of modernizing the popular TR4 and TR5 convertibles, seeing the birth of the TR-250. The same basic design was selected for the new 6-cylinder TR6, but with some modifications and revisions, primarily to the back-end design by Karmann in Germany. The result was an aggressively-looking sports car with equally impressive performance.

The TR6 had pile carpets on the floor and in the trunk, plush-looking bucket seats, a wooden dashboard, and a full complement of instrumentation.

The examples exported to the United States were given carburetors, while the European versions received fuel injection. The fuel injection system provided more power, but the carbureted versions were more dependable and were emissions compliant. The six-cylinder carbureted engine was carried over from the TR250, while the UK version was from the TR5 and included the Lucas mechanical fuel injection system. The 2.5-liter fuel-injected engine produced 150 horsepower in 1969. The over-head valve carbureted engine displaced 152.4 cubic inches and produced just over 100 horsepower. It had two Zenith-Stromberg carburetors, a cast-iron block and head, four main bearings, and solid valve lifters. Disc brakes were in the front, while drums were in the back.

Production lasted from 1969 to 1976, with more than 94,000 examples built. Ninety percent of those were built to U.S. specification (83,480 examples were exported, and 8,370 remained in the United Kingdom). This was Triumph's best-selling car of the TR range.
