Summary

As part of multi-pathway approach toward carbon neutrality, Toyota is focusing on H₂ as a powertrain fuel and has been developing FCEVs for many years. To further expand the adoption of H₂, Toyota has developed a new H₂ engine for light commercial vehicles.
The new engine is based on a V6 3.5-liter petrol turbocharged engine. Over 95% of its components are carried over, and it achieves a thermal efficiency of 39.3%. Additionally, it minimizes engine-out emissions by a lean combustion system and meets the regulatory standards equivalent to Euro 7. Furthermore, Toyota has addressed H₂-related challenges such as H₂ embrittlement, abnormal combustion, and the impact on components in low-temperature environments. The engine has undergone various durability tests and on-road testing to enhance its reliability.
Toyota will deliver light commercial vehicles equipped with H₂ engines to customers, contributing to the realization of a carbon-neutral society.
