1934\u21921935 Voisin C25 A\u00e9rodyne<\/h1>\n

The height of Gabrielle Voisin’s vision was reached with the A\u00e9rodyne, a four-seat fastback that exemplified France’s love for aviation.<\/b> But unlike anything else from the period, Voisin was able to utilize modernist lines where the other design houses couldn’t escape French Curves.<\/span><\/p>\n

The A\u00e9rodyne’s story began in summer of 1934 when Voisin created a prototype to be later displayed that fall at the Paris Motor show. With it, he was trying to draw attention to his innovations such as a sliding sunroof, radial engine and new style that was different from the previous No\u00ebl-No\u00ebl Telmont lines.<\/p>\n

Lightweight expression is one main theme of the A\u00e9rodyne. Examples of this can be seen in the slender fenders which required support struts, an open cockpit and small headlight surrounds.<\/p>\n

Another focus of the car is the retractable roof which shapes the entire fastback roofline and closes directly onto the top of the windshield. The unit is pneumatic and relies on a twin-cylinder suction engine that is mounted in the trunk. Operation of top is slow, but nearly silent. Several windows were put into the sunroof to provide rearward vision at various positions.<\/p>\n

Aimed at the top of the market, the A\u00e9rodyne was fully equipped with features such as Dufaux-Repusseau dampers which could be adjusted from the dashboard. A full bevy of Jaeger gauges also complemented the dashboard and Lalique ashtrays were included in the doors.<\/p>\n

Chassis details of the C25 were not far off the C24 with an altered rear box section. The sleeve-valve inline-6 remained largely untouched except the front radiator fan was driven by a belt instead of gears.1<\/sup> The unit was attached to a two speed gearbox with electromechanical overdrive.<\/p>\n

The sleeve valve engine replaced the standard poppet valves with moving sleeves that surrounded the piston to uncover intake and exhaust ports. This complex system worked without return springs, and enabled very high engine speeds with less stress than a conventional pushrod design. The resulting quieter ride offset the slight haze left by the exhaust as oil slipped between the sleeves.<\/p>\n

While the intention was to make two dozen Aerodynes, only a few examples were really completed, including our feature car which won Best of Show at the 2011 Pebble Beach Concours d’Elegance. The small production numbers were a direct result of the poor economy at the time coupled with a high price tag.<\/p>\n

Several sources have listed that seven A\u00e9rodynes were produced and that four cars survive. We can only definately say that we’ve photographed three separate examples.<\/p>\n
