2 CV Prototypes - TPV - Très Petite Voiture (Very Small Car)

Right despite a total prohibition on any photographs of the TPV, this photograph was taken at the Bureau d'Etudes in Ferté-Vidame during road tests in 1939.

Below this TPV prototype was displayed at the Classic Motor Show 2009.

For years it was believed that only this vehicle and the pickup had survived and then, in 1995,  an additional three cars were found in a barn at the Bureau d'Etudes but unlike the car above which has been fully restored, these have been left pretty much as they were found.

The war years gave the company time to revise and simplify the design.

By 1942, the TPV was beginning to look much more like the car that was revealed in 1948 although only a single headlamp was fitted. 

Mechanically too, it was far closer than the 1939 models - the over--complicated torsion bar springing had been replaced by the familiar inter-connected longitudinal coil springs of the production vehicles. 

Transmission was only three speed and the engine was a 700 cm3 flat twin.

The cars made widespread use of duralinox - a lightweight aluminium alloy but more conventional (and cheaper) materials were employed in the production vehicles.
