Toyota and Yamaha are developing a hydrogen V8 engine. Their goal: to save internal combustion

  • 7

Yamaha and Toyota reinforce their commitment not to let internal combustion engines die. Of course, hand in hand with hydrogen. In a scenario marked by the transition to a fully electric model, a process in which most manufacturers have already embarked, the two Japanese brands have just announced a new effort in the development of more efficient and environmentally friendly combustion engines. environment. both companies have decided to join forces in the development of a 5.0-liter V8 engine for automobiles that runs entirely on hydrogen.

The announcement is part of the commitment of both Asian multinationals to the use of hydrogen, which plays a key role in Japan’s plans to achieve energy independence and a neutral carbon footprint. In November 2021, in fact, Toyota and Yamaha, along with three other major Japanese firms -Mazda, Kawasaki and Subaru-, came to the fore together to show your decision to collaborate in the search for “ways to expand the range of fuel options for internal combustion engines”. The goal: secure your future while pursuing “carbon neutrality”which forces radical changes in the industry.

More than a substitute for gasoline

“Hydrogen engines have the potential to be carbon neutral while keeping our passion for internal combustion engines alive,” claims Yoshihiro Hidaka, president of Yamaha Motor, in a statement in which the company informs of Toyota’s order for the development of the high-performance V8. The executive guaranteed that the firm has set itself the goal of achieving CO2 neutrality in 2050, but making it clear that they have no plans to give up internal combustion: “We have a great passion and level of commitment.”

At the end of 2021, the company already showed its V8 hydrogen model based on the 5.0-liter engine of the luxury sports coupe. Lexus RCF, with modifications to the injectors, cylinder heads, intake manifold and offering 450 hp at 6,800 rpm and 540 Nm of torque at 3,600 rpm. Yamaha began to develop the hydrogen engine for automobiles, in fact, five years ago, and claims it as more than just a “gasoline substitute”. Toyota also has a long experience with hydrogen. The Mirai, with a fuel cell, is an example of its commitment to this route.

The plans of car brands to end combustion models and manufacture only electric cars

“Everyone who came to test the prototype started out a little skeptical, but in the end they left with a big smile on their face. As I watched this, I started to believe that there really is huge potential in the unique characteristics of hydrogen engines,” comments Takeshi Yamadapart of the Japanese firm’s Technical Research and Development Center team.

Hydrogen technology presents, in any case, problems that go beyond its power or the “feels” —for example, preserving the strong sound of the 8V— on which Yamaha claims to be working. As Motorpasión recallstwo of its weak points are storage and energy density. In the racing Corolla used by Toyota, in fact, it is stored in a 700-bar pressure tank that occupies the entire rear of the car.

The Toyota Corolla model that participated in the 2021 Super Taikyu with a hydrogen engine.

Another of its drawbacks is that it consumes a certain amount of oil. While waiting to know the indications of the new V8, the calculations of CO2 emissions that exist with the Corolla hydrogen engine show that it would face problems, for example, in an EU that wants to de facto ban the marketing of internal combustion engines by the middle of the next decade.
