[1][2][3] Sima was an acronym, the letters standing for "Société Industrielle de Matériel Automobile".
[4] The company was founded at Courbevoie on the northwestern side of Paris, in a part of the city which was already home to numerous automobile manufacturers and suppliers.
Marcel Violet who created the little vehicle was a long-standing advocate of two-stroke air-cooled boxer-format engines, and these powered the cyclecars that carried his name[1] Sima Violet ended production in 1929, to be succeeded at their Courbevoie site by the Sima-Standard business which survived till 1932.
[1][4] In the years following the First World War the French government used taxation policy to encourage cyclecars.
The Sima-Violet cyclecar was powered by a two-stroke twin-cylinder air-cooled engine of 497cc mounted in a low-slung position ahead of the driver.
