"article": "Stellantis announced its STLA One platform during Investor Day 2026, marking a major step in its automotive strategy. The platform will launch next year and support 30-plus models, targeting over two million units by 2035. It covers B, C, and D segments, including the next-generation Peugeot 208 and Vauxhall Corsa, as well as larger SUVs like the Peugeot 5008. STLA One features a modular, multi-energy design, allowing flexibility across propulsion systems without production inefficiencies. Stellantis claims this approach will reduce costs by 20% while increasing component recycling and reuse by up to 70%. The platform also integrates advanced technologies like 'cell-to-body' battery integration, developed with Chinese brand Leapmotor, improving rigidity and reducing weight. Software innovations include the 'STLA Brain,' a central computing system akin to BMW’s 'Neue Klasse,' alongside steer-by-wire technology and the 'STLA Smartcockpit' for enhanced driver interaction. Autonomous driving capabilities will be enabled through 'STLA AutoDrive.' The platform launch aligns with Stellantis’ £52 billion 'FaSTLAne 2030' strategy, which includes 60 new vehicle launches and 50 significant refreshes by the decade’s end. The company emphasizes sustainability and efficiency, positioning STLA One as a cornerstone of its future growth.
