Avoins Voisins, often seen as simply Voisin, was a French manufacturer that was established in 1905. Founded by Gabriel B. Voisin, the Voisin name was already well known in the aviation world, but in 1919, the company decided to branch out in the motoring world. Voisin cars highly regarded for their forward thinking technology and models such as the C1, C3, and C4 helped showcase these qualities. Production of Voisin automobiles ended in 1939 due to WW2, and operations wouldn't resume after the war.
