Claude Hill

Just before the outbreak of World War Two Aston Martins's designer Claude Hill was given the job of designing a new car which became known as the Atom. Although production plans were put into abeyance for the war years, development work continued on a part time basis and when time permitted Hill was able to design a new four cylinder engine.

In standard form the car was powered by Claude Hill's 1970 cc four cylinder push rod five bearing crankshaft engine which produced around 90 HP though performance could be improved with a high compression (raised from 7.25:1 to 8.5:1) Spa cylinder head. Apparently 115 HP could be achieved with a 10:1 compression ratio and special flat top alloy pistons.
