[2] Designer Louis Bionier began development of a small two-box "voiture populaire" (people's car) that would be powered by engineer Louis Delagarde's new air-cooled two-cylinder boxer engine driving the front wheels.

[4] The resulting prototype was also a small front-wheel drive car powered by an air-cooled two-cylinder boxer engine.

When the Pons Plan to rationalize the French automotive industry went into effect the company on the Avenue d'Ivry, now simply known as Panhard, was denied permission and access to materials needed to continue building cars.

[5] Bionier and Delagarde developed a new car called the VP2 that substituted a chassis of two tall narrow steel box members and cross-bracing for the AFG's Alpax unitary unit.

He observed the shapes and movements of birds and fishes and built scale models of a streamlined 7-passenger car he named the VP6.

[9] Following the introduction of the Dyna X, Bionier returned to those early studies and built a concept car to explore how they might be applied to a full-sized vehicle.

[11] The car was designed to seat four people although the narrow body and curving roof-line limited passenger space.

[8] Its engine produced 28 hp (20.9 kW) at 4000 rpm which enabled the car to reach a top speed of 131 km/h (81.4 mph).

[9] This car remained the property of Panhard and was eventually permanently loaned to the Cité de l'Automobile museum in Mulhouse.
