The history of Bristol Cars began in 1945. Forecasting a significant excess labour capacity postwar, the Bristol Aeroplane Company (BAC) began working with AFN Ltd, makers of Frazer Nash cars, on plans for a joint venture in automotive manufacture. By July 1945 BAC had created a Car Division and bought a controlling stake in AFN. HJ and DA Aldington remained Directors of AFN and were joined on the Board by Reginald Verdon-Smith and George Middleton White, both sons of BAC Directors. Reginald Verdon-Smith was elected Chairman and HJ Aldington Managing Director.
By mid 1947, the different intentions of the Aldingtons and Bristol were becoming clear and Bristol severed its ties with AFN, returning control of AFN to the Aldington family. Earlier in 1947 BAC had registered the company Bristol Cars Ltd although it continued for several years to market its cars as made by the Bristol Aeroplane Company.
The first car, the 1947 Bristol 400, was heavily based on pre-WW2 BMWs. The body looked very like the BMW 327, while its engine and suspension were clones of BMW designs (engine and front suspension based on those of the BMW 328, rear suspension from the BMW 326). Even the famous double-kidney BMW grille was carried over intact. Until 1961 all Bristol cars used evolutions of the 6-cylinder BMW-derived engine. This very well regarded engine also powered a number of sports and racing cars, including all post-war Frazer Nash cars (apart from a few prototypes), some ACs, some Lotus and Cooper racing cars, and several others.
