Stellantis Unveils STLA One: A Modular Platform Supporting Over 30 Models

Stellantis, the multinational automotive giant, has unveiled the STLA One platform—a modular vehicle architecture designed to support multiple powertrain systems and various vehicle sizes.

Scalable Modular Engineering

The STLA One features a scalable modular architecture with common interfaces aimed at reducing complexity and accelerating development processes, while targeting a 20% cost efficiency improvement driven by modular design and new battery options.

Production Strategy Through 2030

The STLA One supports Stellantis' strategy—the world's fourth-largest automaker—to optimize and evolve its vehicle platforms. By 2030, the company aims to produce 50% of its vehicle volume across three global platforms, with up to 70% component reuse. This strategy is designed to reduce time-to-market, enhance supply chain stability, and improve cost efficiency.

Chief Engineering Officer's Statement

Ned Curic, Stellantis' Chief Engineering and Technology Officer, said: 'STLA One is a clear example of a true modular strategy that gives us multi-energy platform flexibility without the inefficiencies of transitioning from one powertrain to another.'

Covering B, C, and D Segments

The STLA One covers B, C, and D segments through a new modular architecture developed under the concept of 'energy-on-demand by design,' aiming to optimize efficiency for each powertrain type from the outset.

The platform represents a pivotal step in Stellantis' drive to enhance cost competitiveness, streamline operations, and close the cost gap with top-performing companies in Europe.

Other Key Strategic Advantages

Streamlined operations at scale: An advanced technological architecture designed to reduce complexity while expanding market coverage. Global reach: Built to support more than 30 models and scale for production across multiple markets.
