The Paris based Société des Études Automobiles M. A. Julien presented its first prototype in 1946 and automaking activities came to an end in 1949, probably without any of the developments having progressed beyond the prototype stage.
The company presented its first prototypes at the Paris Motor Show in October 1946 (78 years ago) (1946-10).
During the following twelve months Julien negotiated successfully with the government, who controlled the necessary materials supplies, for permission to put the MM5 into production.
The open-topped two-seater car featured a single-cylinder two-stroke engine of 310 cc (19 cu in) which for 1947 was increased to 325 cc (19.8 cu in) with a maximum power output of 10 hp (7.5 kW).
