Stellantis commits €1bn to Peugeot models at Mulhouse

The STLA One investment adds to France’s case for remaining a significant node in Stellantis’ global manufacturing network

Stellantis has committed more than €1bn (US$1.16bn) in France to produce three new Peugeot electric and hybrid models at its Mulhouse plant in Alsace, based on the new STLA One modular platform. The vehicles will enter production in 2029, competing in the C-segment, which accounts for roughly 30% of European car sales.

The commitment covers development of STLA One in France and production of the three models at Mulhouse. STLA One is a modular architecture designed for multiple powertrains and vehicle sizes, targeting a 20% cost reduction through simplification at scale.

The launches form part of the FaSTLAne 2030 strategic plan unveiled in May 2026, under which Peugeot is among four Stellantis brands identified as having the strongest potential for volume and profitability. Peugeot is the first brand to build on the STLA One platform, which is designed for global deployment. The Mulhouse plant, which employs 4,500 workers, will see improved capacity utilisation, with Stellantis describing the commitment as securing the facility’s future amid the sector’s transition to electrification.

In a statement, Antonio Filosa, Chief Executive of Stellantis, said: “I am very pleased to announce these investments in France for the production in Mulhouse of three 100% electric and hybrid models from the Peugeot brand. This decision attests to the professionalism and exceptional commitment of our teams. France perfectly exemplifies Stellantis’ global strategy, presented in our FaSTLAne 2030 plan, where our global scale, our in-depth local knowledge, and our brands come together to meet and exceed our customers’ expectations.”

Why this matters:

• The political choreography is as significant as the investment. Stellantis hosted two French government ministers at Mulhouse on the day of the announcement and explicitly credited government industrial policy as a condition for the investment decision. That is not incidental: it signals a transactional relationship in which state support through the Made-in-Europe framework and EV purchase incentives is part of the commercial calculus. The €1bn (US$1.08bn) figure needs to be read with that context in mind.

• STLA One is the real story; Mulhouse is the illustration. Consolidating five existing architectures into a single platform targeting 20% cost efficiency is a structural move with consequences across the entire Stellantis portfolio. Peugeot being the launch brand in the C-segment—Europe’s largest single sales category at roughly 30% of the market—means the platform’s commercial validation will come fast, and the results will determine how aggressively Stellantis rolls it out across Fiat, Jeep and the rest of the brand hierarchy.

• 2029 is a long runway in a sector moving quickly. STLA One vehicles will debut elsewhere from 2027; Mulhouse does not begin production until two years later. For a plant running below capacity now, that gap is manageable only if European EV demand and the regulatory environment hold reasonably steady. Neither of these are guaranteed given the ongoing EU emissions framework negotiations and the uncertain trajectory of consumer incentive programmes across member states.
