The Voisin C28 was an autombile that was made in 1935.

The C28 took centre stage at the 1935 Paris Auto Show. It came complete with new engine and hydraulic brakes (which Voisin had years earlier dismissed as outright dangerous). Otherwise, it had very few changes compared to previous models. The C25 chassis was unchanged, as was the interior. The body styles remained the same as the previous year. Clairière for the saloon and Cimier for the two-door. Only the Chevalière limousine evolved significantly, and was rebaptised as the Chancellerie.

Of the thirty C28s built, some were rather special. One client specified a long chassis version to accommodate his extensive luggage requirements. Fitted with rear wheel spats, this one-off was coded as the Ambassade, a name applied the following year to a similar model on the standard chassis.

Aerosport C28

There were only 14 C28 Aérosports made. They had a profiled back, sliding roof on a lowered roof line and wings integrated into the body. The body line would be perfect without the prominent headlights and the high Voisin radiator grill which seems to hinder all of the efforts of aerodynamism that had gone into the rest of the body.
