Stellantis will end vehicle assembly at its Poissy plant near Paris by 2028, winding down production of the DS 3 and Opel Mokka — including their battery-electric variants — and redirecting €100 million into a components-led remake of the site.

A Stellantis spokesperson confirmed the timeline to Reuters, saying both nameplates will continue at Poissy "until at least 2028." After that, the plant stops building cars. The site itself stays open.

What does the phase-out change for Poissy?

The plant is heading toward a two-track future. Track one: components. Poissy already builds parts shipped to other Stellantis assembly plants. That business will continue and expand, with the announced €100 million earmarked for new activities — 3D printing of parts, plus vehicle refurbishment and recycling, per Reuters' union-talk reporting.

Track two: jobs. The roughly 1,600 employees at Poissy today face an unresolved transition. Stellantis has not disclosed how many assembly workers will shift into the expanded components operation. The union consultations have not produced a headcount.

The capacity math behind the call

Poissy is running far below historic levels. The plant is expected to build around 68,000 vehicles this year, falling to roughly 65,000 units in 2027. For context: output topped 145,000 cars in 2023. At its 1976 peak, the site rolled out approximately 500,000 vehicles and employed 27,000 people.

Stellantis carries overcapacity across Europe, a structural hangover from the 2021 merger of PSA and Fiat Chrysler Automobiles. The combined group rationalised platforms and shared parts between closely related models — efficiency that left multiple plants underused. Covid-era demand swings deepened the imbalance.

Where the next DS 3 lands

Stellantis already signalled the migration. The next-generation DS 3 E-Tense, due in 2027, will not come from Poissy — production moves to the group's Zaragoza, Spain, facility, Stellantis said in autumn 2024. A future Opel electric SUV built on Leapmotor technology is also reportedly slated for Zaragoza.

Could a Chinese partner fill the empty halls?

Stellantis is in talks with Dongfeng, its Chinese joint-venture partner, about how the state-owned automaker could access Stellantis's unused European production capacity, per a Bloomberg report. Dongfeng could speed its European market entry and sidestep EU tariffs on Chinese-built EVs by assembling at Stellantis plants — or acquiring one outright. Similar talks with Xiaomi and Xpeng have surfaced since March.

A freshly emptied Poissy could fit that template. Stellantis has not confirmed any such deal. The group operates four other vehicle assembly plants in France besides Poissy.

What to watch next

• Workforce numbers from the ongoing union talks, especially the components-side headcount and any transition package for assembly workers.
• A signed agreement — or silence — on Dongfeng, and whether Poissy is named.
• The 2027 start of DS 3 E-Tense production in Zaragoza, the first concrete proof of Poissy's wind-down.
• Any EU-level capacity review Stellantis might trigger across its remaining French footprint.
