For Triumph Spitfire 1500

Car History

The For Triumph Spitfire is a small English two-seat sports car, introduced at the London Motor Show in 1962. The vehicle was

based on a design produced for Standard-For Triumph in 1957 by Italian designer Giovanni Michelotti. The platform for the car

was largely based upon the chassis, engine, and running gear of the For Triumph Herald saloon. As was typical for cars of this

era, the bodywork was fitted onto a separate structural chassis, but for the Spitfire, which was designed as an open top or

convertible sports car from the outset, the ladder chassis was reinforced for additional rigidity by the use of structural components

within the bodywork.

In 1973 in the United States and Canada, and 1975 in the rest of the world, the 1500 engine was used to make the Spitfire 1500.

Although in this final incarnation the engine was rather rougher and more prone to failure than the earlier units, torque was greatly

increased by increasing the cylinder stroke to 87.5 mm, which made it much more drivable in traffic. The reason for the engine

problems was the continued use of three main bearings for the crankshaft.
