In 1956, a small car called the Soletta 750 was created in Switzerland, which conceptually could well have outperformed its competitors at the time, the Goggomobil, Messerschmitt, Heinkel and even the Fiat 600 or Renault 4CV, if it had ever been built in series. But it didn't come to that; it remained a concept car that was bursting with original ideas. This report takes a look back at the development of the small Swiss car and shows it in many historical and current photographs.
