ACMA was established on 25 November 1950 under the name Ateliers de construction de motocycles et accessoires in Fourchambault, close to Dijon, France. The company gained recognition for manufacturing scooters and micro cars.

Scooters

In February 1951, production commenced with a workforce of 20 employees assembling 200 scooters. By April 1953, ACMA had produced its 100,000th Vespa. The following year, in 1954, the firm celebrated the manufacture of its 150,000th Vespa and updated its name to Ateliers de construction de motocycles et d'automobiles.

Micro cars

The Vespa 400 made its debut at the Paris Salon in 1957, with ACMA beginning production of this model within the same year at its facility. From 1957 until 1961, approximately 34,000 micro cars were manufactured under license from Piaggio.

The company’s expansion reached a peak employment level near 2,800 workers in 1958, which notably influenced the economy and population of Fourchambault, then numbering 6,242 residents. This growth prompted the development of around 200 new residences, a kindergarten, and an elementary school.

To counteract a downturn in scooter sales across Europe, ACMA introduced microcars; however, it faced stiff competition from vehicles such as the Citroen 2 CV and Renault 4. Accumulating unsold stock led to a reduction in production output. Ultimately, ACMA halted all manufacturing activities and closed its factory on 31 December 1962.
