What Happened
STLA One is a scalable platform that covers B, C, and D vehicle segments and supports multiple powertrains, including battery electric, through a modular design with common interfaces. Stellantis says the platform will reduce complexity, shorten development time, and target 20% cost efficiency, driven by modularity and new battery choices.
“STLA One is a clear example of a truly modular strategy, giving us the flexibility of a multi-energy platform without carrying inefficiencies from one propulsion system to another.”
- Simplification at scale: Advanced technology architecture designed to reduce complexity while expanding market coverage.
- Global reach: Designed to support 30-plus models and grow to more than 2 million units by 2035.
- Modular by design: Modular interfaces deliver best performance for each energy type, supporting different powertrains.
