53An accomplished club racer who had enjoyed some notable successes with his Cooper MG 1.5 litre sports racer 'JOY 500', London-based car dealer Cliff Davis decided to move up to the 2 litre class for the 1953 season. To this end he commissioned talented engineer John Tojeiro to design an all independently sprung chassis which could accommodate Bristol's tunable 2 litre engine. Bodied in the style of a contemporary Ferrari Barchetta by Eric Hall and Bill Rich, the resultant aluminium-skinned machine was road registered as 'LOY 500'. Well balanced and fast, the Tojeiro-Bristol had a magnificent season and even won the support race at the Dutch Grand Prix beating the 2 litre Maseratis.
Davis suggested to Tojeiro that the sports racer could form the basis of a production model and thus earn some money. Learning that AC Cars Ltd were looking for a project, Tojeiro took 'LOY 500' to the firm's Thames Ditton factory for evaluation. The Directors were impressed and could see a future in the design. Suitably evolved it debuted at the London Motor Show as the AC Ace (John Tojeiro being paid £5 per car in royalties).
