AVL unveils high-performance hydrogen combustion engine prototype with Over 200 HP per liter

AVL’s hydrogen combustion engine achieves remarkable power output, targeting a sustainable future for motorsport.

AVL, a renowned mobility technology company specializing in automotive development, simulation, and testing, has introduced a prototype hydrogen combustion engine with impressive specifications. Developed by AVL’s motorsport division, this powertrain boasts incredible performance, showcasing the potential of hydrogen combustion technology.

The engine was tested at AVL’s headquarters in Graz and delivered astounding results: 405 horsepower at 6,500 rpm and 369 lb-ft of torque between 3,000 and 4,000 rpm. This equates to an extraordinary power output of 203 horsepower per liter. Surpassing the 100-hp-per-liter club, AVL’s achievement is a groundbreaking step in the automotive industry.

To comprehend this engine’s significance, it’s essential to differentiate between hydrogen-electric and hydrogen-combustion vehicles. While hydrogen-electric cars like the Mirai use hydrogen to generate electricity for their batteries, hydrogen-combustion vehicles, like Yamaha’s YXZ1000R, directly inject hydrogen into a traditional combustion engine.

AVL further enhanced its engine with intelligent PFI water injection, introducing additional water into the intake air to prevent premature injection. This technology not only enhances performance but also improves engine longevity.

Despite these remarkable advancements, the hydrogen combustion engine remains primarily for motorsport applications. However, motorsport serves as a crucial testing ground for new technologies that may eventually find their way into production vehicles. In 2021, AVL announced a partnership with Ineos to develop a hydrogen fuel cell version of the Grenadier, indicating the potential for hydrogen combustion engines to become a part of the automotive landscape.

Ellen Lohr, Director of Motorsport at AVL, expressed their commitment to sustainability in motorsport, emphasizing that AVL’s H2 racing engine demonstrates their ability to deliver a highly competitive technology package. This prototype marks a significant step towards a more sustainable future for motorsport.
