Stellantis has announced investments of more than €1 billion in France to enable the production of three future Peugeot electric and hybrid models in the C-segment, based on the new STLA One platform. These three new vehicles will be assembled at the Mulhouse industrial site (Alsace), starting in 2029.

Stellantis said these investments will contribute to both the development in France of the new STLA One modular platform, as well as to the industrial production of the three new models in Mulhouse.

The projects are also described as fully aligned with the FaSTLAne 2030 strategic plan, presented on May 21, 2026, a key pillar of which is to develop new global platforms, powertrains, and technologies. STLA One is a new modular, scalable architecture supporting different powertrains and vehicle sizes, designed to accelerate development cycles and targeting a 20% cost efficiency through simplification at scale.

The three upcoming C-segment models from Peugeot will be 100% electric or hybrid. These launches play a key role within the context of FaSTLAne 2030’s, aligning with two strategic pillars:

• Sharper management of unparalleled brand portfolio: Peugeot ranks among the company’s four global brands with the ‘strongest potential in terms of volume and profitability’. Peugeot is the first brand to launch the STLA One platform, a technology designed for global implementation.
• Regions and Local Teams Empowerment: These investments in the C-segment, which accounts for approximately 30% of total car sales in Europe, are part of Stellantis’ European strategy to strengthen the Company’s market coverage in Europe.

Furthermore, Stellantis said the production of these models in Mulhouse, starting in 2029, demonstrates the ambition to combine electrification with high industrial performance in France, a key country in the company’s strategy. These investments will boost capacity utilisation at the Mulhouse plant – which employs 4,500 employees and is a historic asset for the company - and will secure the future of the plant by providing long-term visibility amid a period of profound transformation in the automotive sector.

“I am very pleased to announce that the Mulhouse site has been selected to produce three 100% electric and hybrid models from the Peugeot brand. This decision attests to the professionalism and exceptional commitment—particularly in terms of industrial quality and performance—of our employees over the past few years,” said Antonio Filosa, CEO of Stellantis, speaking from Mulhouse in Alsace. “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.”
