In Suzhou, China, the deployment of city-scale digital twin infrastructure is rapidly advancing, enabling real-time V2X operations and high-precision traffic data acquisition. Leveraging this cutting-edge environment, Nissan Mobility Service is pioneering commercial operations of L4 robotaxis and engaging in co-creation innovation with cross-industry partners. This keynote will highlight the evolution of AI and SDV (Software-Defined Vehicle) and explore the potential of AI-DV (AI-Defined Vehicle), where AI leads the continuous growth of vehicles. What if cars could become “learning and evolving platforms”? Could OEMs generate new “mobility-plus” value beyond transportation and build innovative revenue models together with other industries? Through concrete future scenarios in collaboration with energy, entertainment, and retail sectors, we will explore—together with the audience—the roadmap toward the next-generation mobility ecosystem.
