TR3

.
The Triumph TR3 was a car built between 1955 and 1959 by the Standard Motor Company in the United Kingdom, during which time 13,377 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.

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 (71 kW; 96 PS) increasing to 100 bhp at 5000 rpm. The four speed manual 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.

In 1957, it was replaced by an updated version, the TR3A.
