The history of the BMW Isetta

After the resumption of motorcycle production in 1948 and the restart of automobile production in 1952, the difficult years for BMW were far from over. Although the production of the hard-to-sell luxury cars of the 501 and 502 series restored the brand name to its former glory, it did not improve the company’s difficult financial situation. BMW was once again building automobiles for the “cream of society”, but even the good motorcycle business could hardly finance this luxury. The time was ripe for a small car – the BMW Isetta.

The heyday of scooters and microcars

Around 1954, it became clear that BMW would not survive without a model that was easy to sell and inexpensive to produce. However, a completely new development of an automobile would no longer have been financially viable for the company. It was the heyday of scooters and microcars, and so the search was on for a high-quality small vehicle that BMW could build under license. They soon came across an egg-shaped mobile with a front door from the Milan-based company Iso. After careful examination, this very original and practical “Isetta” was found to be suitable for rolling off the production line as a BMW small car after certain modifications. The license agreement was signed.

A motorcycle engine for the Isetta

Instead of the two-stroke engine, the Isetta was fitted with the single-cylinder four-stroke engine from the R 25 motorcycle; production started in spring 1955 with 250 cc and 12 hp, followed at the end of the year by the 1 hp more powerful Isetta 300. It quickly became clear that BMW had hit the bull’s eye with this unusual model. Well over 10,000 Isettas were sold in the very first year of production.

Special versions such as the Tropical Isetta

This first version of the Isetta 250 and 300 still largely corresponded externally to the original Italian model. In Munich, however, a different engine cover was used and, after an initial series with long headlight housings, a revised model with smaller housings was offered. There were already export variants with large bumpers and headlights for the USA and special versions such as the “Tropical Isetta” with additional ventilation openings in the front door, the Isetta Cabriolet with a soft top instead of the rear window, or the cargo Isetta with a tiny loading area.

Export version of the Isetta

A revised Isetta with a modernized body appeared at the end of 1956. It bore the name BMW Isetta Export. The previous model was called the BMW Isetta Standard and was offered at a lower price for a few more months. The Export Isetta 250 or 300 produced from November 1956 was very different from the previous version. Similar to a coupé, the roofline was now continuous and numerous details had given way to more modern solutions. Like the previous model, the Isetta Export could also be ordered in various special versions and country versions.
