The last car factory in the Paris region, in Poissy, west of Paris, will stop producing vehicles by 2028. Stellantis management officially announced the decision to the plant's workers on Thursday, April 16, during a works council meeting. The company insisted that the site, which currently makes Opel Mokka and DS3 models, will stay open, but will switch to making replacement body parts.
Since the 2021 merger of PSA and Fiat Chrysler to form Stellantis, the European auto market has declined sharply, forcing the group to manage significant industrial overcapacity. Workers no longer expected a new model to be introduced on their assembly lines. Bloomberg has reported that representatives from Chinese automaker Dongfeng have recently visited other Stellantis plants as they seek to manufacture in Europe to avoid tariffs.
Car sales in Europe are still about 20% below 2019 levels, and the market is now stabilizing around 13 million passenger vehicles per year in greater Europe, including the United Kingdom. Stellantis has lost market share, so workers in Poissy were not surprised by the decision announced to them by plant director Eric Haan and Stellantis' head of human resources, Xavier Chéreau, one of the few members of Carlos Tavares' management team still in place under the new CEO, Antonio Filosa.
