Announced at Nvidia GTC 2026, the Isuzu and TIER IV Level 4 autonomous bus combines Autoware software with Nvidia’s DRIVE AGX Thor compute.

Isuzu’s Level 4 Autonomous Buses Powered by Nvidia’s DRIVE Hyperion Platform

Isuzu Motors, in collaboration with Japanese autonomous driving software company TIER IV, has announced the deployment of Level 4 autonomous buses built on Nvidia’s DRIVE Hyperion computing platform, covering both the Isuzu ERGA electric and diesel models.

The announcement was timed to coincide with Nvidia GTC 2026, an AI global conference held from March 16 to 19, 2026, in San Jose, California. The vehicles combine TIER IV’s Level 4 software stack built on Autoware, an open-source autonomous driving framework, with Isuzu‘s bus platforms and Nvidia’s DRIVE AGX Thor system-on-chip, which delivers 2,000 TFLOPS of processing performance with ASIL-D safety compliance. This architecture is designed to provide the redundancy required for public transit operations.

Shinpei Kato, founder and CEO of TIER IV, noted that the deployment is proof that scalable autonomous public transit is already a reality. “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. 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,” Kato said.

For Isuzu, the partnership with TIER IV and Nvidia represents a significant leap in commercial vehicle intelligence. “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,” Hiroshi Sato, Senior Executive Officer and Vice President of Engineering at Isuzu, explained.

Meanwhile, Nvidia’s Vice President of Automotive, Rishi Dhall, pointed out the practical urgency behind the development. “Their scalable solution addresses critical real-world needs, such as Japan’s national driver shortage, while delivering the operational rigour necessary for essential public services,” he noted.

Level 4 autonomy refers to vehicles that are capable of handling all driving tasks within defined conditions without requiring human intervention.
