In order to be able to present his innovative project study Soletta 750 at the Geneva Motor Show in the halls of the major vehicle manufacturers and not in the accessories hall, Willy Salzmann, an engineer from Sölden, had designed the entire vehicle in just six weeks. Originally, it was about the possible market launch of his design of the elastic axle; a mixture of rigid and oscillating axle.

If you want to show the axle in passenger cars, you have to show it in a passenger car� Salzmann was told a few weeks before the opening of the show. Together with the specialists from Carosserie Hess in Bellach, a small car with a 750 cc mid-engine from the motorcycle manufacturer Condor was built in a very short time.

The ingenious arrangement made it possible to build identical doors, front and rear windows. Other components were taken from the 4CV, known as the Renault Tail.

On schedule, the Soletta was exhibited in Geneva in 1956 and then in Paris. The media response was excellent. Well-known magazines such as �auto motor sport� reported positively on the innovation. One English newspaper even saw it as �the right economy car for Great Britain!�. Also hidden is the statement of the engineer Alec Issigonis, the later inventor of the �Aus- tin Mini�, upon seeing the Soletta 750, that there will be a market for exactly these vehicles. All in all, there was a lot of recognition, international publicity, offers and contacts with high-ranking automotive managers. Unfortunately, nothing came of it, because: "I was just a designer, and even back then I couldn't do it without management and marketing," Willy Salzmann later reported.

Today, the Soletta is owned by the Swiss Car Register in Safenwil, which is dedicated to the preservation of the Swiss automobile as a cultural asset.
