The BMW Isetta is a microcar built by BMW under license from Iso, the original creators of the car. The Isetta saw three main variants over the course of production, the 250 (1955-1956), the 300 (1956-1962), and the 600 (1957-1960). Powered by a variety of motorcycle engines, Isettas were small and light cars featuring two seats, except for the four seat 600. Built until 1962, the Isetta was a successful car for BMW, even if not all of the variants sold as well as hoped.
