Galba was a French automobile produced between 1929 and 1930 by the Société Sylla, a company founded in Courbevoie, on the northern side of Paris, by Marcel Violet. Violet was an automobile engineer who had previously created the Sima-Violet cyclecar and had a particular specialization in two-stroke engines.
The only model produced was a small "voiturette" (light car) with a wheelbase of 2,250 mm (88.6 in). It was powered by a 564 cc two-stroke twin-cylinder engine mounted at the front, which drove the rear wheels via a two-speed transmission and shaft drive.
Despite a lengthy development period, the Galba was short-lived. By October 1930, Marcel Violet had introduced the Huascar, a very similar voiturette produced at the same Courbevoie factory but with a slightly larger engine, under a new company called "Voiturettes Huascar." The Galba was one in a succession of cars designed by Violet, a respected engineer in the French cyclecar and light automobile market of the late 1920s and early 1930s.
