The anglais Renzo Rivolta, patron of Iso SpA Coolers de Milan, made in 1950 refrigerators. The sales decline in refrigerators (Isothermos) Renzo Rivolta leads to turn to scooters. However, competition from Vespa and Lambretta forces him to change his plans. He then gives carte blanche Gobini to design a totally original vehicle, capable of transporting two adults and one child, and some luggage, safely. in parallel, engineers Ermenegildo Preti patented in 1950, an ovoid shape of prototype vehicle with a front door and three wheels.

Thus in 1952, Ermenegildo Preti and Pierluigi Raggi engineers are mandated by Rivolta, instead of Gobini, and imagine a small vehicle powered by a motorcycle engine, modern forms and practices, which took over the prototype features, but this time with four wheels for stability. Preti said to have been inspired by a cargo plane to draw the front. The name given to it is Isetta, that is to say small ISO. The car made a splash at the show in Turin 1953. With solutions adopted, the car is offered at a competitive price. It creates a lot of interest as a city car.

The journalists of the time, during their trials the Isetta, were pleasantly surprised by the space feel of the cart. A press release indicates that even the large windows Plexiglas allow a clear view in all directions. There are handles to open the roof and uncover the sun. Two adults and one child can sit comfortably on the bench. However, to avoid movements in the cabin, the shift lever is located on the left and other manual controls are conveniently grouped on the steering column.

After a very difficult start in Italy, where its production is confidential due to competition from Fiat 500, this original buggy sees its manufacturing license was sold in 1955 several manufacturers, including BMW in Germany, while its production stops this year in Italy. Moreover, it is this model that ensures the survival of the German mark to the edge of bankruptcy in the mid 1950. When three Isetta won the first three places in the index performance Mille Miglia, in 1954, BMW observers are impressed and speak to the firm, looking at the time a second wind. The war destroyed not only the bulk of the production units, but also left its Soviet-controlled Eastern factories. The small BMW Isetta sells well at the beginning, due to its low fuel consumption, whose prices have risen sharply in the years 1950, and in particular 1956, during the Suez Canal crisis. Velam, in France, and ISO Romi, in Brazil, are also interested in golf cart.
