Stellantis STLA One is a modular vehicle architecture designed to support multiple powertrains and vehicle sizes. STLA One will have a modular, scalable architecture with common interfaces to reduce complexity, speed development and targets 20% cost efficiency, driven by modularity by design and new battery choices.

STLA One covers B, C and D segments with a new modular architecture engineered with dedicated per energy by design to optimize efficiency for each propulsion type from the start. STLA One is also a key step in Stellantis’ push to compete on cost, simplify operations and strengthen competitiveness, closing the cost gap with best-in-class players operating in Europe.

STLA One supports Stellantis’ platform optimization strategy. By 2030, the Company targets 50% of volume on three global platforms, with up to 70% component reuse. This platform strategy is designed to shorten time to market, strengthen supplier stability and improve cost efficiency.

“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,” said Ned Curic, Chief Engineering and Technology Officer.
