Triumph TR6 History (1969-1976)
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 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 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.
TR6 Engine Specs
The UK market TR6 had Lucas mechanical fuel-injection (150-horsepower), while the US market TR6 was fitted with a carbureter (104-horsepower). In 1973, the UK fuel-injected version was de-tuned to 125-horsepower through a camshaft change and revised fuel injection metering. These changes made the TR6 engine smoother and more flexible.

The base transmission was a manual 4-speed gearbox. An optional overdrive unit was available, and gave drivers close gearing for aggressive driving, with overdrive available on 2nd, 3rd and top gears on early models.
Acceleration from the 2.5 litre six-cylinder engine was quick; 0-60 mph in just 8.2 seconds. Equally impressive was a top speed of 120 mph.
Inside, a wooden dashboard (plywood w/veneer) housed a full complement of instrumentation. Bucket seats sat on pile-carpeted floors, and the luggage compartment was fairly roomy for a two-seat sports car.
TR6 Production Figures
The Triumph TR6 remained in production for a relatively short period of time, but has became one of the most popular and instantly recognizable cars in the company's stable. Most of the TR6 sales were in the U.S. - of the 94,619 models produced, 86,249 were exported, with just 8,370 sold in the U.K.
When Triumph TR6 production ended in July 1976, it was the best-seller in the TR series (this record was later surpassed by the TR7). Of the 8,370 cars sold in the U.K., over 4,000 are still registered with the DVLA either as on the road or as SORN declared vehicles.
The Triumph TR6 is an attractive, fast and very enjoyable two-seater. Of the many sports cars made in Great Britain, it remains as one of the most popular. With unmistakable looks and powerful performance, the TR6 continues to be a sought-after classic.
