The German based company of Bayerische Motoren Werke, more formally known as BMW got its start from the merger of three other manufacturing companies coming together in 1916. Initially the company produced aircraft engines but were forced to cease production per order of the Treaty of Versailles. Then producing various farm equipment, railway brakes, household items, motorcycles engines, and other small manufacturing pieces in order to stay in business. In 1929, after the purchase of Fahrzeugfabrik Eisenach who produced Austin Sevens, BMW began manufacturing cars. At first turning Austin Seven cars into 6-cylinder luxury vehicles, with the first car produced entirely by BMW arriving in 1932 still influence by its Sevens predecessors. The BMW 328 was released in 1936 with its own redesigned 2-liter overhead valve 6-straight petrol engine the M328. The 328 experienced instant race success at its introduction in the Eifelrennen race, and more in the following years with more than 100 wins in 1937.
During the start of World War II in 1939 production of cars had ceased, BMW had shifted its focus to aircraft engines to supply the German war machine, with motorcycle production as a side. After the war was completed in 1945 BMW returned to making household items and bicycles in order to survive the financial struggle Germany faced after the war. Motorcycle production restarted in 1949, and automobile production of pre-war BMWs in the Soviet controlled East Germany began shortly after but halted again in 1955. Still facing financial struggle and the lack of sale from the BMW 501, BMW began manufacturing the Italian designed Isetta. The Isetta was a smaller more economic car, with a much smaller price tag compared to other BMW models, producing more than 10,000 the first year. During the end of the 1950's BMW moved more toward family vehicles and was the first use of the semi-trailing arm.
