After Forming Alliance With Other Japanese Manufacturers, Toyota and Yamaha Are Already Showing the Fruit of This Junction and Decided to Present the First V8 Engine Powered by Hydrogen in the World
At the request of Toyota, Yamaha developed a V8 engine (eight cylinders, in a “V” format) with a capacity of 5.0 liters, intended for hydrogen-powered vehicles. This new project is related to a new alliance formed between Toyota, Yamaha, and other Japanese automotive companies, aimed at expanding fuel options for internal combustion engines, proving that electrifying vehicles is not the only sustainable solution for the mobility of the future.

Even though Yamaha is famous for its motorcycles, the Japanese manufacturer has also invested in producing engines for cars. Yamaha even manufactured high-performance engines for Formula 1 that were used in Tyrell, Brabham, and Jordan cars in 1990.
The hydrogen-powered eight-cylinder engine developed by Yamaha for Toyota is fully based on the 5.0-liter engine of the luxurious Lexus RC F sports car. The engine underwent changes in injectors, cylinder heads, intake manifold, among other components, so that it could be fueled with the liquefied chemical element.
Alliance Between Japanese Manufacturers
In November 2021, Japanese companies Kawasaki Heavy Industries, Subaru Corporation, Toyota Motor Corporation, Mazda Motor Corporation, and Yamaha Motor, announced that they formed an alliance to conduct collaborative research on the feasibility of expanding fuel options for internal combustion engines as an alternative to electric engines that are seeking carbon neutrality.
About 5 years ago, Yamaha began developing a hydrogen engine and, according to Takeshi Yamada, the engineer responsible for the automotive development department at Yamaha’s Technical Research and Development Center, the manufacturer believes in the potential of using hydrogen as fuel for high-performance engines.
Fascination for Internal Combustion Engines
Takeshi notes that he has observed that engines that only used hydrogen as fuel had excellent performance characteristics. According to him, the hydrogen engine is friendly, making it easy to use even if one has to resort to electronic driving aids.
The Yamaha engineer truly believes there is enormous potential in these unique characteristics of the hydrogen engine and seeks not to treat it merely as a substitute for gasoline.
Another highly valued characteristic throughout the development process was the sound emitted by the exhaust of the eight-cylinder engine. Takeshi stated that Yamaha is looking for not only engine performance but also to stimulate a new fascination for internal combustion engines.
