Car manufacture started for BMW when it purchased Fahrzeugfabrik Eisenach in 1928. Eisenach were trading as 'Dixi' selling the Austin Seven under licence as the Dixi 3/15 which now became the BMW Dixi 3/15. The Bayerische Motoren Werke AG (B.M.W.) had been formed in 1917 as a manufacturer of aircraft engines, which gave the company its roundel badge designed to resemble a spinning propellor. The Versailles Treaty of 1919 forbade Germany to manufacturer aircraft and so BMW turned to making motorcycles, gradually taking an interest in making cars which was a dream only realised by buying out an existing manufacturer. The Austin Seven licence deal ended in 1932 and by then BMW had produced its own AM1 model similar in concept. By 1933 BMW was building 6-cylinder engines and even had a V8 before the end of the decade. Postwar, production resumed but with the Eisenach factory now lying in Eastern Germany that part of the business produced cars under the 'EMW' label and later as 'Wartburg' after an Austin Seven-based sports car. In the 1930s Frazer-Nash sold BMW cars in Great Britain and even assembled some of them, badging them 'Frazer-Nash BMW' This arrangement was terminated by the War, and after the war the Bristol Aircraft Company bought the rights and developed the one- time BMW 6-cylinder engine for its own unit to power the new Bristol Cars from 1948. German BMW only restarted car production with the 501 in 1951, having resolved naming rights with EMW, but the concentration on large luxury cars was not profitable. In 1954 BMW agreed to build the ISO Isetta bubble car under licence in Germany, but using its own BMW motorcycle engine. Success here saw BMW develop this into the BMW 600, a 4-seater bubble car, and then into the BMW 700 conventional looking car designed by Michelotti but still using a rear-mounted BMW motorcycle engine. But in 1962 BMW launched the 1500, a front-engined saloon which is recognisable as the ancestor of the current BMW 3-series and therefore of all modern BMWs. BMW purchased Glas in 1966, reputedly to acquire rights to timing belt design. BMW owned Austin Rover from 1994-2000.
