Hyundai Motor Company and autonomous driving software firm Plus have introduced the first Level 4 autonomous Class 8 hydrogen fuel cell electric truck in the U.S. at the Advanced Clean Transportation (ACT) Expo in Las Vegas. The XCIENT Fuel Cell truck is currently undergoing initial autonomous driving assessments, showcasing the future of self-driving technology in the commercial transportation sector. This collaboration between Hyundai and Plus aims to illustrate how autonomous hydrogen fuel cell trucks can improve safety, efficiency, and sustainability in trucking operations. The advanced capabilities of Level 4 autonomous vehicles, such as the ability to operate in self-driving mode and intervene during system failures, are integrated into the XCIENT Fuel Cell truck. Plus's SuperDrive solution, utilizing state-of-the-art sensors like LiDAR and cameras, enhances the truck's surround perception and self-driving features. Both companies express excitement about the potential for autonomous hydrogen fuel cell trucks to revolutionize the industry and contribute to a more sustainable transportation ecosystem.
