Gabriel Voisin’s name is one of the most highly regarded in France because of the advanced designs that he produced. He was initially a builder of airplanes, in fact it was Voisin who built the first French airplanes on a commercial basis. He always associated automobiles both technically and in appearance with aircraft. They were original and futuristic cars, but were also powerful and luxurious, belonging mainly to royalty and aristocracy.

For his first car Voisin had bought the manufacturing rights to an 18 CV sleeve valve engine form Andr? Citro?n, which Citro?n had obtained from Panhard and then decided that it did not suit their needs. This engine powered Voisin’s C1, which was a sports model developing 150 bhp at 4,000 revs. The touring version developed 80 bhp at 2,500 revs and had a top speed in fourth gear of 93 mph and 65 mph in third. The C3 followed, and this also had a very good performance. Finally came the C5. This model differed in having magnesium pistons and a higher compression ratio. It developed 100 bhp at 2,700 revs and had servo-assisted brakes.
The last design of Voisin was a mini car powered by a 125 cc engine called the Biscooter. This highly original model was popular in Spain.
