HJ Aldington, a director of the Bristol Aeroplane Company affiliated AFN (BMW's pre-war concessionaire in the UK), used his British Army connections to visit the bombed BMW factory in Munich several times post-war. In 1945 he took plans for BMW cars back to Britain, and BMW chief engineer, Dr. Fritz Fiedler was also employed. Its first car was the Bristol 400, prototyped in 1946 and introduced at the 1947 Geneva Motor Show. Derived from immediately pre-WW2 BMW products (thanks to a connection to BMW through Frazer Nash), the chassis was based on the BMW 326, the engine on the 328, and the body on the 327. Even a variation on the famous double-kidney BMW grille was retained. Bristol, however, did a thorough examination of the car's handling and ended up with performance "only matched by outright purpose-built competition cars". Seven hundred of the Bristol 400 were built, 17 of which received "handsome" drophead bodywork from Pininfarina.
