The Triumph TR3 was a car built between 1955 and 1957 by the Standard Motor Company in the United Kingdom, during which time 13,377[4] cars were produced, of which 1286 were sold within the UK while the rest were exported mainly to the USA. As of 2002 there were only 893 registered TR3/3a's on UK roads. [5]
Although the car was usually supplied as an open two seater, an occasional rear seat and bolt on steel hard top were available as extras.
The car was powered by a 1991 cc Straight-4 OHV engine which initially produced 95 bhp increasing to 100 bhp @ 5000 rpm.[3] The four speed transmission could be supplemented by an overdrive unit on the top three ratios electrically operated and controlled by a switch on the dash. In 1956 the front brakes changed from drum to disc becoming the first British series production car to be so fitted.[6].
