Offered as an affordable, six-cylinder sports car, the first Triumph TR6 rolled off the production line in 1968 as a 1969 model. It’s intended target was to rival similar sports cars at the time, and although most were designed with sleek, curved lines, the Triumph TR6 was squared off at both ends, making it stand out from it’s competitors. With just a seven year production span, the TR6 grew to become a true British classic.
Triumph produced a range of TR models, from the TR1 right up to a limited run of the TR8, but it was the sixth car in the range that really stood out from a sales point of view. The TR5 enjoyed a very brief thirteen-month period of manufacture between 1967 and 1968. Less than 3,000 units were produced before the Triumph TR6 came in to improve on many of the specifications. Unlike its predecessors, the Triumph TR6 was more reliable mechanically, which means that there are many original models still on our roads.
The Triumph TR6 was offered as a convertible only, with a factory steel hard top available optionally. Construction was conservative; the body was bolted onto the frame, which featured a front anti-roll bar, rack and pinion steering, and semi-trailing arm independent rear suspension. Disc brakes were fitted at the front with drum brakes at the rear. The iconic look of the TR6 was completed by very distinctive 15-inch wheels and tires.
The U.K.-market TR6 had Lucas mechanical fuel-injection (150-horsepower), while the U.S.-market TR6 used a carbureted version (104-horsepower). The UK fuel-injected version was de-tuned to 125-horsepower in 1973 by camshaft alterations and revised fuel injection metering. These changes made the TR6 smoother and more flexible. The 2.5 litre six-cylinder engine accelerated the two-seater car from 0-60 mph in just 8.2 seconds, with an equally impressive top speed of 120 mph.
