Hydrogen-powered Buggy Finishes Fourth in Class at Dakar 2024: Insider Look (Segment 2)
HySE-X1 Hydrogen Buggy Makes Impressive Debut at Dakar 2024
The HySE technical research association, a collaboration between six Japanese companies, made a significant debut at the 2024 Dakar Rally with their hydrogen-powered buggy, the HySE-X1. Despite facing numerous challenges, the team managed to complete over 80% of the rally, placing an impressive fourth among ten vehicles in Mission 1000.
Leadership and Collaboration
Tomohiro Nakano from Toyota led the control program development team for the HySE-X1, serving as the project manager. The project was a collaborative effort, with engineers from Kawasaki Motors, Suzuki, Honda, Yamaha Motor, and Kawasaki Heavy Industries all working together. Despite Toyota never hosting another company's engineers, the necessary arrangements for collaborative development took time to make.
Development Challenges
The project was beset by unforeseen trouble and a rather demanding schedule. The team started developing the HySE-X1 in August 2023, with a test run scheduled in Portugal for November. However, the vehicle faced several issues during testing, including a problem with the chain that transfers the driving force from the engine to the CVT, which kept breaking.
Engine Calibration and Improvements
Engine calibration for the HySE-X1 was carried out at Yamaha Motor headquarters in Iwata. Hiroshi Nishiyama from Suzuki was responsible for figuring out how the displays would notify drivers of engine errors and how to control the engine. Overdrive Racing upgraded from the chain to a gear drive to solve the problem, and the vehicle was able to run all day without stopping during the final preliminary test on January 3.
Fuel Efficiency and Future Plans
The team plans to focus on making combustion more efficient to boost power output and fuel economy without changing the tank capacity for Dakar 2025. They want to address the lack of programming that adjusts how much hydrogen is injected accordingly to improve engine performance at higher altitudes.
Success at Dakar 2025
Despite the challenges faced during Dakar 2024, the HySE-X1 safely crossed the final finish line on January 19, having covered 830 km, or 90% of the 922 km rally (including the prologue stage). The vehicle faced difficulties during Stage 6 on January 11, including a problem with the shaft that transmits drive power to the front wheels, causing the buggy to get stuck in the sand. However, the team managed to overcome these issues, and the HySE-X1 finished the rally in a strong position.
Looking Ahead
The HySE-X1's impressive performance at Dakar 2024 and 2025 demonstrates the maturity and competitiveness of the hydrogen-powered technology developed by HySE. The team is now looking ahead to Dakar 2025, where they hope to build upon their success and continue to push the boundaries of hydrogen vehicle technology.
The collaboration between Toyota, Kawasaki Motors, Suzuki, Honda, Yamaha Motor, and Kawasaki Heavy Industries, collectively known as HySE technical research association, showcased their hydrogen-powered technology in the finance sector, by sponsoring the HySE-X1 in the sports industry during Dakar 2024, a significant racing event in the transportation industry.
The automotive industry was also involved, with Hiroshi Nishiyama from Suzuki addressing engine error notifications and control for the HySE-X1. Additionally, a company in the technology sector, Overdrive Racing, upgraded the HySE-X1's chain to a gear drive to solve a problem during testing.
With the focus on improving fuel efficiency and power output for Dakar 2025, the team aims to make hydrogen-powered vehicles more competitive and efficient in the transportation industry. This development in the finance, automotive, and technology sectors has the potential to revolutionize the sports and racing industries.
