Built by Jean Legeay of Gennes, France, the L’Éclair is a home-built propeller-driven car.

Lancia’s Ardea model was replaced by the Appia in 1953, which remained in production for ten years. Produced in three Series during its run, improvements along the way included a larger trunk, larger rear glass, longer wheelbase, more power, and a larger bench seat.

The Ardea, introduced in 1939, was a “luxury utility” model a size down from its big brother, the Aprillia. The car is similar in layout, but simpler in design, with a solid rear axle and no trunk opening.

This one-of-a-kind, canvas-bodied roadster was created and commissioned by Anatoly “Toly” Arutunoff. The name he gave his unique vehicle, Lapin Agile (LEH-pawn AH-zheel), loosely translates as the Rabbit that Wouldn’t Hold Still, which speaks volumes about the man.

The Larmar holds the claim to be the world's narrowest car.  At 2 ft., 4 in. wide, it was designed to pass through a standard gate that was 2 ft., 6 in. wide.  That's pretty close, as it only leaves 1 in. clearance on either side.

In 1936 French inventor Hippolyte Delimal attempted to create the world's smallest car, which reached a speed of 24 mph and touted fuel economy of 118 mpg. He affectionately named it Le Carabe, or the “Ground Beetle”.

Marcel Leyat was a degreed engineer who designed, built, and flew his first airplane in 1909. Leyat developed the belief that propeller-driven vehicles were the wave of the future, and in 1913, built his first propeller-driven car.
