1955-1956 AUSTIN-HEALEY 100M specifications

The potent abilities of the 100 meant that many owners wanted to take their cars racing, so the factory put together an upgrade kit which could either be retro-fitted or specified from new. If the latter option was chosen, the car became known as the 100M, the letter standing for ‘Modified.’ In 1955, the 100M became a model in its own right. Its engine - tuned to Le Mans specification - boasted 110bhp, the strapped-down bonnet had louvres in it to help keep it cool, and there was stiffer suspension and an anti-roll bar. 1159 were made.
