It wasn't until 1928 that production began on the first BMW automobile, the Dixi. The car proved tremendously popular, and its success helped the manufacturer weather the Depression. BMW's best-known pre-World War II vehicle was the Type 328 roadster, a supple two-seater that racked up over 120 victories on the motorsport circuit between 1936 and 1940. Postwar BMW cars maintained this tradition, winning several racing, rallying and hill climb victories.
The early 1950s saw the launch of the BMW 501, a roomy, voluptuous sedan that was resplendent with all of the hopefulness of that era. It was soon followed by the 502 which was powered by the world's first light-alloy V8, foreshadowing BMW's ongoing commitment to developing new technology. The best-selling BMW of that decade was the Isetta, a petite two-seat "microcar" typically powered by a 12- or 13-horsepower engine. The mid-'50s also saw the debut of the limited production and breathtakingly beautiful 507 sports car which had an alloy body and used the 502's V8 for propulsion. In the 1960s, BMW sales strengthened significantly, thanks in part to the immense popularity of the 1500, a sporty family sedan.
By the 1970s, BMW was establishing itself as a full-fledged car company. It was a pioneer for many emerging technologies, including turbocharging and advanced vehicle electronics. This was also the period when BMW of North America was established and consumers, who coveted both sports and luxury cars became loyal "Bimmer" owners. The '70s also saw the birth of BMW's three-tier sport sedan range consisting of the 3 Series, 5 Series and 7 Series cars and the creation of its performance M division.
