At the end of the Second World War, BMW found itself in a difficult economic situation. Its most important passenger car plant now belonged to the Soviet occupation zone, while the Munich plants had been used for aircraft engines and military motorcycles and were not directly available. The first car developed after the war, the 501 "Barockengel", sold moderately well. For large sections of the population, the car was simply unaffordable, and many did not even have a car driver's license. So-called scooters such as the Messerschmitt Kabinenroller or the Goggomobil dominated the market. BMW, on the other hand, only had motorcycles or the luxury class in the form of the 501 to offer. And its poor sales prevented the budget for the development of a small car. Meanwhile, a few hundred kilometers to the south, Renzo (Iso) Rivolta, until then a manufacturer of motorcycles and refrigerators, launched the Iso Isetta, a scooter that German customers could use. A small metal ball on three wheels, powered by a two-stroke twin-piston motorcycle engine. A vehicle so minimalist and compact that it didn't even have side doors. Instead, the entire front swung open thanks to a mechanism inspired by cargo gliders. BMW decided to build it under license after seeing the little vehicle at the Turin Motor Show, but not without a few improvements. The BMW Isetta was given a second rear wheel (which was immediately dropped in some markets so as not to be considered a passenger car), an air-cooled four-stroke single-cylinder engine from the motorcycle division (first 245, then 298 cc) and a reverse gear. With these improvements and a slightly refined design, the BMW Isetta was launched on the market in 1955. It sold like hot cakes and made the "Knutschkugel" from Munich not only the most successful of the various licensed models, but also a symbol of the economic miracle. Less than a year after the Isetta 250 went on sale, it became the Isetta 300, with a displacement increased by 53 cc to 298 cc, bringing 1 hp and 4.5 additional Newton meters. In 1957, BMW also launched the BMW 600, inspired by the Isetta, in principle a 20 cm longer Isetta with rear seats and side doors in addition to the front entrance. Production of the BMW Isetta ended in 1962 after 161,728 units, and if the "big Isetta" (600) is included, another 35,000 were produced. The model still enjoys a large fan base today, and there are still licensed models, some of which are now electrified.
