The P4 is an unarmoured off-road vehicle used by the military of France. It was manufactured by Peugeot but is now manufactured by Panhard. It is to be replaced with the PVP by Panhard.
The Peugeot P4 is a light, unarmoured, four-wheel-drive vehicle manufactured by Peugeot, and used by the Military of France under the designation of "Véhicule léger tout-terrain" ("Light all-terrain vehicle"). It is based on the Mercedes-Benz G-Class and equipped with Peugeot engine and equipment.
In the late 1960s, the French army decided that its 10,000 Jeeps needed to be replaced. The replacement vehicle would carry four men with radio equipment and would be small enough to be parachuted and transported by plane.
After many technical issues, the new vehicle was designed in the 1970s. An agreement was settled between Peugeot and Mercedes to co-produce the vehicle by a proportion of 50% each. Peugeot mounted the engine of the Peugeot 504 and the transmission of the Peugeot 604 on the Mercedes-Benz G-Class; it also installed the electrical systems, welded the exterior and painted the car. The rest was done by Mercedes. Peugeot did not have a licence to export the vehicle anywhere else than to the African countries bound to France by defence agreements. The plant in Sochaux did the final assembly. The first prototype was tested in 1978, beginning a long series of tests and trials, notably a rally in south Algeria with a petrol and a diesel P4.
The French Army ordered 15,000 P4s, both petrol and diesel versions; in 1981, order downgraded to 13,500 units with the downsize of the Army. From 1985, production was transferred to Panhard in Marolles-en-Hurepoix, where 6,000 vehicles were produced.
