Background
Introduced in 1955, the TR3 was an evolution of Triumph’s 1953 TR2. The original TR cars had proved so popular and effective on road and track that Triumph sensibly opted to update the design rather than reinvent it. As a result, the new model shared the overall body shape and 1991cc engine with its predecessor, and that was absolutely fine, as it offered the sporting driver just under 100bhp, which may not seem like much these days, but the American magazine Car and Driver described the lightweight TR3’s acceleration as “neck-snapping.” While this might have been something of an exaggeration, a sub-11 second time for the benchmark sprint was impressive for its era.
In fact, that power output meant the TR3 was actually more powerful than competitors such as the Porsche 356, Sunbeam Alpine, and MGA, with a top speed of a little over 100mph.
However, the engine wasn’t the only aspect in which this compact sportscar excelled. The TR3 was the first production car fitted with disc brakes. After testing this innovation at the 1955 Le Mans 24-Hour race—during which it achieved numerous racing victories between 1955 and 1959, including winning the Liège-Rome-Liège rallies in 1956 and the Sebring 12 Hours in 1957—Triumph introduced it to TR3 buyers in 1956, putting cutting-edge, race-car technology into a reasonably priced sports car.
How reasonable? Well, the TR3 cost around £1,103 back in the day, which is approximately £20,000 today, making it considerably cheaper than ‘affordable’ sports cars like the Mazda MX-5.
