102 bhp, 3,318 cc inline sleeve valve six-cylinder engine, four-speed Cotal epicyclic preselector transmission with overdrive, solid front axle and live rear axle with semi-elliptical leaf springs, and four-wheel hydraulic drum brakes.


It was in the design of coachwork that Voisin himself shone. Although he had come of age with the airplane, he was not accomplished in aerodynamics as it is now understood. His mantra was simplicity, which expressed itself in flat sheets of aluminum, stark in their primitive beauty, and lightness of weight. By the mid-1930s his designs had evolved into an Art Deco vein, still incorporating aircraft-like features such as the “suspenders” that supported the front fenders from the radiator shell—a particularly Voisinesque bit of functional beauty.

Voisin’s masterpiece is considered the C28 Aérosport, a dramatic two-door berline, debuted at the 1935 Paris Salon. This radically innovative design exemplified Voisin’s guiding principles of aerodynamic stability and lightness in a thrilling body with a steeply raked windshield, a broadly curving roofline, and fenders that flow straight through to the tail of the car in an all-enveloping style. Low-slung and ultra-streamlined, the Aérosport is considered the first production full-width “pontoon” production body and is, for all purposes, the original gran turismo design, with power and comfort to spare.

On the C28 chassis with its Cotal four-speed gearbox with electromagnetic clutches and overdrive, the car could reach a top speed in excess of 90 mph, while the Lockheed brakes ensured safe, smooth stops, and made it a delight to drive.

Unfortunately, this ultimate Voisin came into being at a time when the company that built it was financially strapped and nearing the end of its life. It is believed that some eight to ten examples of the Aérosport were produced. Of those, only two examples are known to exist. One, a well-known car that has appeared at many concours d’elegance over the years, is a long-term part of one of the world’s most significant private collections and is unlikely to ever become available for sale. The other is that offered here in Monterey.
