At its 2025 Technology Day, GAC Toyota a joint venture between Toyota Motor Corporation and Guangzhou Automobile Group unveiled its roadmap for advancing electrification, smart mobility, and software innovation. Key alliances with tech leaders Xiaomi, Huawei, and Momenta are central to this strategy. Highlights included the debut of two new energy vehicle (NEV) platforms, an advanced electronic architecture, and three distinct hybrid systems, all launched under Toyota’s localized innovation initiative, “China R&D 2.0.”
A new battery electric vehicle (BEV) platform, optimized for compact and midsize cars, will debut with the bZ3X model, which emphasizes space optimization and cutting-edge technology. Meanwhile, a second multi-energy architecture is designed to support BEV, plug-in hybrid (PHEV), and range-extended electric vehicles (REEV) in larger formats, accommodating vehicles up to 5.3 meters in length. The platform’s first model, the premium bZ7 sedan, will integrate LiDAR and is planned for release in March 2026.
Toyota is also pursuing a multi-pronged approach to hybrid technology. Its fifth-generation Intelligent Hybrid Dual Engine system is being rapidly deployed, with a sixth-generation version already in development. A new high-performance PHEV system—designed for stronger acceleration and longer range—will be introduced by 2027 in upcoming Chinese versions of the Sienna and Highlander.
Xiaomi Alliance: Smart Ecosystem Integration
In a first-of-its-kind partnership for Xiaomi with a global automaker, Toyota is integrating Xiaomi’s AIoT (Artificial Intelligence + Internet of Things) ecosystem into its vehicles. With the bZ7, Xiaomi devices such as tablets and smart speakers will sync seamlessly with in-car systems, enabling connected experiences across home and vehicle platforms.
Huawei Partnership: HarmonyOS and AI Cockpit Development
Toyota’s bZ7 will also debut Huawei’s HarmonyOS 5.0 infotainment system, powered by a Kirin chipset and a large 15.6-inch screen. This collaboration enhances the vehicle’s compatibility with China’s digital infrastructure and significantly boosts user interface responsiveness. Alongside Tencent, Huawei and Toyota are also co-developing an AI voice assistant that recognizes individual users and adapts to their behavior—evolving into an intelligent control hub by 2028.
Momenta Integration: Intelligent Driver Assistance Systems
The bZ3X will be upgraded with Momenta’s 6.0 intelligent driving system, incorporating nearly 50 advanced driver-assist functions. The system employs a world model-based approach for perception and decision-making, supporting inputs through voice and gestures. It is trained using simulations to predict and respond to complex driving scenarios. Future updates will introduce real-time environment mapping and collaborative interaction with passengers.
Towards Autonomy: Merging Driver Monitoring with Vehicle Intelligence
By 2028, Toyota aims to unify its cockpit intelligence systems with advanced driver assistance features. Upcoming models will feature sensors capable of monitoring driver posture, fatigue, and eye movement, creating a feedback loop where vehicle behavior adapts to the driver’s state—a vision Toyota describes as a “co-evolutionary cabin-driving model.”
A new digital chassis control platform will also be introduced, utilizing SDC electromagnetic dampers and dual-chamber air suspension systems. This tech reduces body roll by 6%, cuts braking jolt by 50%, and enhances ride comfort and stability at high speeds.
Toyota’s next-generation electronic/electrical (E/E) architecture can support over 300 software modules and full over-the-air (OTA) updates. Additionally, the company has developed an AI-powered Battery Management System (BMS) that offers real-time diagnostics, enhanced thermal safety, and lifecycle monitoring. New insulation materials and containment mechanisms further boost battery safety.
Under the “China R&D 2.0” initiative, Toyota is shifting greater design and development authority to its Chinese teams. Engineers in China are now taking lead roles in future models of the Camry, Sienna, and Highlander—marking a strategic shift from global standardization to localized innovation for the Chinese market.
