TIER IV, Inc. and Isuzu Motors Limited have announced the deployment of Level 4 autonomous buses, leveraging NVIDIA DRIVE Hyperion computing platform, in Isuzu ERGA electric and diesel models. These next-generation autonomous transit vehicles will feature NVIDIA DRIVE AGX Thor system-on-chip on the NVIDIA DRIVE Hyperion platform for essential safety and performance redundancy. Timed to coincide with NVIDIA GTC 2026, the premier global AI conference held March 16-19 in San Jose, California, this announcement marks a major step toward TIER IV's and Isuzu's ambition to safely and scalably deploy autonomous transit.

This effort combines TIER IV's Level 4 software stack based on Autoware, open-source software for autonomous driving, Isuzu's advanced bus platforms, and NVIDIA's AI compute, to create Level 4 autonomous buses optimized for high-capacity public transit. The transition to highly automated commercial transport demands fail-operational, high-performance computing without compromise. TIER IV and Isuzu are frontrunners in the public transit vertical, utilizing NVIDIA DRIVE AGX Thor on the DRIVE Hyperion platform in the Isuzu ERGA to power TIER IV's Autoware-based Level 4 software stack.

Their scalable solution addresses critical real-world needs, such as Japan's national driver shortage, while delivering the operational rigor necessary for essential public services. A complete, production-ready autonomous driving development platform and reference architecture that combines a standardized sensor suite, high-performance AI computing, and a robust software stack to accelerate the development and deployment of autonomous vehicles. An automotive-grade system-on-chip that delivers up to 2,000 TFLOPS of performance, with ASIL-D compliance and redundancy for superior safety.
