In 2028, after nearly 90 years, the history of the Poissy automobile plant will come to an end. It has seen many owners: founded in 1938 by Ford, taken over by Simca in 1954, operated by Chrysler starting in 1958, purchased by PSA in 1978, and finally becoming part of Stellantis following the merger with FCA. Stellantis has decided to close the last assembly plant in the Paris region in 2028. An estimated nearly 19 million vehicles have been built there since the postwar period.
Famous Models
After the war, the Ford Vedette was produced, followed by such iconic models as the Simca Aronde, 1100, and 1300; the Talbot Solar and Horizon; the Peugeot 205, 306, and 1007; and, most recently, the Citroën DS3 and Opel Mokka. Poissy is the last plant still in operation in the Paris region, following the closure of the plants in Boulogne-Billancourt (Renault), Quai de Javel (Citroën), Levallois (Citroën), Aulnay-sous-Bois (Citroën), and Flins (Renault) have been closed.
Capacity of 500,000 vehicles
The plant was designed for an annual production of 500,000 vehicles; in the record year of 1976, more than 27,000 employees produced 569,245 cars. By 2025, production had dropped to just 80,000 units with 3,700 workers. The plan is to retain about 1,000 of those jobs when the plant is retrofitted at a cost of approximately 100 million euros and begins producing components starting in 2030.
Car parts are already being manufactured in Poissy today for installation in vehicles at other Stellantis plants. The announced investment is intended to enable new activities such as 3D printing of parts or the processing and recycling of used vehicles.
