[5][4] While some sources say that the car was built in just six weeks, others point out that its appearance at Geneva was announced in 1955, indicating that the design work likely started much earlier.

[5][4] The Soletta 750 was viewed by Sir Alec Issigonis, future designer of the Mini, at the 1956 Paris Show.

[5] Renault, Alfa Romeo, and a government agency in the German Democratic Republic (GDR) all expressed interest in the project, but this did not lead to series production.

In the following years he developed another innovative engine with combined piston and connecting rods and continued to experiment with microcars into the 1990s.

[3] To simplify production and reduce costs, complementary body panels, such as the doors on the right and left, the front "grille" and rear "tailgate" covers, and diagonally opposite fenders, are interchangeable.

It was built by Condor-Werke AG of Courfaivre, who used it in their shaft-driven A750 military motorcycle, a large displacement version of the A580 model whose design was strongly influenced by German bikes from makes such as BMW and Zundapp.

Engine, transmission, and differential together form a single powertrain swing-arm assembly meant to improve ride quality and simplify maintenance.
