Sydney Herbert Allard was the founder of the Allard car company and a successful rally driver and hillclimb driver in cars of his own manufacture.

Allard Motor Company Limited was a London-based low-volume car manufacturer founded in 1945 by Sydney Allard in small premises in Clapham, south-west London. Car manufacture almost ceased within a decade. It produced approximately 1900 cars before it became insolvent and ceased trading in 1958. Before the war, Allard supplied some replicas of a Bugatti-tailed special of his own design from Adlards Motors in Putney.
