Vauxhall 30/98 (1913 - 1924)


This wonderful car was a pioneering high-performance sports car which was produced up to 1922. Designed by Laurence Pomeroy (1883-1941), it was based on the successful Vauxhall Prince Henry design of 1913. The cars were the fastest sports cars of their day, and were successful in sprints, hill-climbs and races at Brooklands. The E types were fitted with a four-cylinder, 4.5-litre capacity side-valve engine, whereas the later models known as the 'OE-type 30/98' had an overhead-valve engine that developed 90 bhp, and were capable of a maximum speed of approximately 100 mph.
