What does Choisy-le-Roi do?

Choisy is part of the powertrain manufacturing department. It has a technical department and an operations department (reconditioning for standard exchange, production). Concerning standard exchange, the site manages seven engine families (1,200 part numbers), JB/JC, JH/JR and PK5/PK6 transmissions, three generations of injection pump (mechanical, digital and common-rail). The site is the main supplier of DPA.

A brief history

Before its acquisition by Renault in 1949, the Choisy le-Roi plant built gliders for Caudron and trucks for SAVIEM.  It went on to begin engine reconditioning for standard exchange but contributed to rebuilding the railcar base of French rail utility SNCF until 1962. From 1959, the plant focused more on the automotive sector and began producing synchronizer rings. In 1980, it produced gear controls for the Renault 9 and 11. The European Centre for the Reconditioning of Powertrain Sub-systems (PEROM in the French acronym) was founded in the early 2000s. In 2004, Choisy began reconditioning K4 and K9 engines, followed by PK gearboxes in 2005.

Environment

Located outside Paris, in the towns of Choisy-le-Roi and Villeneuve-Saint-Georges, the plant is in an area designated for "special protection against atmospheric pollution". The plant has easy access to major roads and is close to Orly airport. Flanked by the River Seine to the west, it is close to two drinking water production plants.  The nearest homes are some 100 meters away.
