Yamaha is working on a very special project for Toyota. It wants to run a V8 on hydrogen and now Yamaha is sharing the first details about what turns out to be possible. Those are impressive.
Toyota firmly believes in hydrogen as an alternative to conventional propulsion. That ‘belief’ is quite broad, because Toyota does not only focus on fuel cells that generate electricity with hydrogen. The Japanese also want to use hydrogen as a fuel. Think of the Toyota GR Yaris Hydrogen, in which the pretty bright 1.6 from the regular GR Yaris does not run on petrol but on hydrogen. With a revised fuel supply and different injection system, the Japanese finally managed to run it on hydrogen. Now they take it one step further by doing this with a V8 as well.
It has been known for some time that Yamaha is working on a hydrogen V8 for Toyota, but now Yamaha is letting us know what it has achieved so far. The 5.0 V8 is in fact the block we know from the Lexus RC F (photo 3), in which the power source is good for a power of 457 hp and a maximum torque of 520 Nm. Yamaha has managed to get the hydrogen version to deliver comparable performance. The power is maintained at 457 hp, the maximum torque is even slightly higher with 540 Nm. Yamaha states that it has modified the injectors, cylinder heads and the intake manifold, among other things, to make this possible with hydrogen as fuel.
The result is a still very strong V8, which now no longer emits harmful substances. Yamaha Motor CEO Yoshiro Hidaka is pleased with the future potential of the fuel engine, he believes this shows: “Hydrogen engines have the potential to be carbon neutral yet keep our passion for combustion engines alive. In combination with different company cultures and areas of expertise We want to usher in the future in this way.”
