The Triumph Spitfire was a small British two-seat sports car, introduced in October 1962. The vehicle was based on a design produced for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti. The codename for the vehicle was the "Bomb". The car was largely based on the Triumph Herald saloon, and throughout its life was built at the Standard-Triumph works at Canley, Coventry.
In 1973 in the United States & Canada and 1975 in the rest of the world, the 1500 engine was used to make the Spitfire 1500; though in this final incarnation the engine was rather rougher and more prone to failure than the earlier units, torque was greatly increased which made it much more drivable in traffic. The reason for the engine problems was due to continued use of three main bearings for the crank shaft.
While the rest of the world saw 1500s with the compression ratio reduced to 8.0:1, the American market model was fitted with a single Zenith-Stromberg carburettor and a compression ratio reduced to 7.5:1 to allow it to run on lower octane unleaded fuel and after adding a catalytic converter and exhaust gas recirculating system, the engine only delivered 100 bhp (75 kW) with a fast 0
