TIER IV and Isuzu Motors have announced that they will be utilizing NVIDIA’s DRIVE Hyperion autonomous driving solution in developing autonomous buses that will be classified as Level 4 autonomous vehicles. The autonomous buses will be based on Isuzu’s ERGA electric and diesel buses and will utilize NVIDIA’s high-performance DRIVE AGX Thor system-on-chip solution to provide enhanced safety and redundancy capabilities.
The announcement comes in conjunction with NVIDIA’s GTC 2026 event and represents a major milestone in the development and provision of safe and autonomous public transportation systems. TIER IV’s autonomous driving software solution, which is based on Autoware, will be combined with Isuzu’s commercial vehicle platforms and NVIDIA’s AI computing capabilities to provide next-generation autonomous vehicles that meet high-capacity urban mobility requirements.
“This collaboration marks a definitive milestone for autonomous transit,” said Shinpei Kato, founder and CEO of TIER IV. “By fusing Isuzu’s legendary engineering with NVIDIA’s Thor AI compute, we have built an unmatched foundation for Level 4 transit driven by Autoware. Unveiling this Level 4 autonomous bus deployment at NVIDIA GTC 2026 proves that when you combine world-class hardware with the power of the Autoware ecosystem, safe and scalable public transit is no longer a goal – it is a reality.”

Advancing Autonomous Public Transportation
The move is part of the larger effort of integrating AI-based autonomous systems into the infrastructure of public transportation systems, helping solve problems such as efficiency, safety, and the lack of drivers. The solution is expected to enable the use of autonomous buses in the real world by employing software-defined autonomy and high-performance compute.
“Our partnership with TIER IV and NVIDIA represents a significant leap in commercial vehicle intelligence,” said Hiroshi Sato, Senior Executive Officer and Vice President, Engineering Division of Isuzu. “Deploying Level 4 autonomous driving on both our ERGA EV and diesel models ensures that we provide versatile, sustainable, and highly efficient solutions for any fleet. We are bringing Isuzu’s world-renowned reliability to the autonomous age, ensuring safe and high-performance transit at scale.”
High-Performance AI Compute for Safety-Critical Systems
The NVIDIA DRIVE platform’s integration allows for fail-operational computing, ensuring system performance even in the presence of hardware or software failure—a critical need for autonomous public transportation. The utilization of the NVIDIA DRIVE AGX Thor improves processing for real-time perception, decision-making, and control—a critical need for Level 4 autonomy.
“The transition to highly automated commercial transport demands fail-operational, high-performance computing without compromise,” said Rishi Dhall, Vice President of Automotive at NVIDIA. “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.”
Enabling Scalable, Sustainable Mobility
With the help of open-source autonomous driving software, existing commercial vehicle platforms, and advanced AI computing capabilities, this partnership is expected to result in the faster development of Level 4 autonomous transit solutions. This partnership is considered timely and is expected to help address the requirements for sustainable mobility solutions while increasing the convenience of public transportation services.
The above development is considered a major milestone in the development of fully autonomous buses, especially for regions where labor is a concern and the requirement for efficient transportation solutions is high.
