On 16 January 1932, the High Command of the French Army initiated a Automitrailleuse de Cavalerie type Reconnaissance (AMR) project for a modern armoured car.
Panhard, Renault, Peugeot and an independent inventor, Mr Gendron, took part in this project.
As Mr. Gendron noted that the French Army did not have the budget to buy expensive armored vehicles, he decided to maximise the price quality ratio by creating an unusual wheel configuration of 3x1 for the prototype.
An additional metal wheel with grousers was connected to the side to enhance cross country performance.
A single sided hexagonal turret from the AMR 33 tank was mounted in the middle of the hull.
