Toyota Motor is accelerating development of its in-house Arene software platform as part of its push toward software-defined vehicles. The platform will enable over-the-air updates, advanced driver assistance features, and improved integration across vehicle systems, marking a shift from traditional hardware-focused engineering.

Executives said the move is essential to compete with tech-driven automakers and EV startups. By building a unified software architecture, Toyota aims to shorten development cycles and improve customer experience, while also opening new revenue streams through digital services.
