By Jordan Park

Stellantis plans to build 2 million cars per year on its STLA One architecture by 2035, aiming for a 20% improvement in competitiveness versus its current platform and cost parity with Chinese automakers in Europe. The platform is slated to begin production in Spain in 2027 with the new Peugeot 208 and was showcased at the Mulhouse plant as part of efforts to address excess capacity through plant sharing and targeted facility investments.

Key Points

  • Stellantis projects production of 2 million vehicles annually on the STLA One platform by 2035, targeting scale advantages in Europe - impacts the automotive manufacturing sector and European industrial activity.
  • The company claims STLA One will be 20% more competitive than its current architecture, aiming for cost parity with Chinese automakers in the European market - relevant for auto pricing, supply chains, and competitive dynamics.
  • STLA One production will begin in Spain in 2027 with the new Peugeot 208; the platform was displayed at the Mulhouse plant as part of capacity and product-investment planning - affects regional production sites and facility investment decisions.

Stellantis said Tuesday it expects to produce 2 million vehicles annually on its STLA One platform by 2035, company chief executive Antonio Filosa announced. The target is a central element of the automaker's recently unveiled strategy, which positions STLA One as a cost-focused architecture for the European market.

Filosa said the new platform will be about 20 percent more competitive than the group's current architecture. That relative improvement is intended to bring Stellantis to cost parity with Chinese automakers operating in Europe, a stated goal for the company as it seeks to sharpen its pricing and manufacturing profile on the continent.

According to the timeline provided by the company, STLA One will enter series production in Spain in 2027, where it will underpin the manufacture of the new Peugeot 208. The platform was put on display at Stellantis' Mulhouse plant, a facility the company says has been adapted to support the economics and production requirements of the new architecture.

Management also outlined how the group is confronting structural issues in Europe, including excess industrial capacity. Filosa noted the company is pursuing plant-sharing arrangements in some locations - Rennes was cited as an example - while also adding new products at sites such as Mulhouse to better match capacity with expected demand and platform rollout.

The announcements underscore a focus on unit-cost competitiveness and manufacturing reconfiguration as Stellantis prepares to scale STLA One across its European operations. The company presented the platform visually at Mulhouse to show how the architecture and associated plant investments will support efforts to align costs with those of Chinese rivals competing in Europe.


Contextual summary

  • Stellantis' goal: 2 million vehicles per year on STLA One by 2035.
  • Platform competitiveness: A claimed 20 percent improvement over current architecture; goal of cost parity with Chinese automakers in Europe.
  • Rollout: STLA One to begin production in Spain in 2027 with the new Peugeot 208; showcased at the Mulhouse plant.
  • Capacity response: Plant sharing (e.g., Rennes) and investment in facilities such as Mulhouse to address excess capacity in Europe.

Risks

  • Long timeline - the production goal extends to 2035, leaving outcomes subject to execution risk and market evolution over more than a decade; this affects capital allocation and manufacturing planning in the automotive sector.
  • Competitive pressure - achieving cost parity with Chinese automakers is a stated objective but depends on realizing the claimed 20% competitiveness gain and broader market conditions.
  • European capacity adjustments - addressing excess capacity through plant sharing and targeted investments introduces operational and integration uncertainties for facilities and workforce planning in affected regions.
