Everything but the same old cars

Voisin C6 Laboratoire avec Propeller

Posted by Mike Bumbeck On September - 10 - 2010

voisin-C6-laboratoire-leadRacing cars with propellers are something we would need more of around here. The propeller on this 1923 Voisin C6 Laboratoire Grand Prix special worked in reverse, utilizing otherwise unused energy borrowed from the blazing 100+ mile per hour top speed of the Voisin to circulate engine coolant in an attempt to keep the near 2000 cubic centimeter sleeve valve straight six from overheating. The Voisin C6 Laboratoire was the first Grand Prix car to use a lightweight monocoque construction and aircraft derived slippery aerodynamics together, but could not break pace against its competitors. Four Laboratories started the 1923 Grand Prix, but only one crossed the finish line. The engine was not enough even for this lightweight car. The propellers spun, but not for victory.

The Voisin C6 Laboratoire shown is an exact replica built from the original plans and parts, on display at the Mullin Automotive Museum in Oxnard, California.

    We think of French manufacturers as marching to the beat of their own drum. Gabriel Voisin marched to the beat of his own bongo. As a result, the state of the art of the car is a lot better off.
