The Voisin C25 was a luxury car which was built between 1934 and 1937.
During the car's production life, 28 chassis of C25 were constructed. Of these, seven received bodywork by Aerodyne, which had an airfoil shape like the wing of airplane. They also had a round constant profile from the roof to the bottom of the body.
Their power came from the engine which was shared by that of the previous model.
A C25 Aerodyne won Best in Show at the Pebble Beach Concours d'Elegance in 2011.
