It was acquired by the Musée des Arts et Métiers in Paris in 1993, and is currently at the Cité de l'Automobile in Mulhouse in Alsace.

[1] Arzens, a Parisian, and graduate of École nationale supérieure des Beaux-Arts de Paris, designed this futuristic, economical, lightweight electric car prototype in 1938 (along with his concept car La Baleine), then built it in 1942, during World War II.

[2] The spherical bodywork, with a fastback rear, is inspired by interwar cyclecars, and the bionic shapes of an egg, a bubble, or a drop of water.

[3] To circumvent fuel rationing during the German military administration in occupied France during World War II, Arzens used an electric motor, which was powered by five 12-volt batteries located under the bench seat.

[3] After the war, Arzens replaced the electric motor with a 125 cc (7.6 cu in) Peugeot single-cylinder petrol engine, which produced 5.5 horsepower (4.1 kW).
