Toyota, Mazda and Subaru want to save the combustion engine

Japanese car and motorcycle manufacturers are campaigning for hydrogen, biofuels and synthetic fuels to support internal combustion engines.

In the 2000s, a few prototypes attempted to make hydrogen an alternative fuel. One of them, the BMW Hydrogen 7, had a V12 powered by this gas. Despite CO emissions2 very weak, the technology was too noisy, at reduced power facing gasoline and low autonomy.

Then, the development of the fuel cell combined with the electric motor struck him the fatal blow. At least that’s what we thought.

The hydrogen engine in the race

In 2021, Toyota created a hydrogen racing Corolla with support from Yamaha. The Japanese manufacturer, a fervent “H2 And critic of the electric, wanted to support its return. This November 13, the Japanese n ° 1 was allied to Mazda, Subaru, Yamaha and Kawasaki to defend the combustion engine as a whole.

Kawasaki and Yamaha have established a union for the development of hydrogen fuel. They aim integration into two-wheelers

, as well as boats or planes. Honda and Suzuki could also join the project, in order “To achieve carbon neutrality on the combustion engine”.

Biofuels and synthetic fuels too

Mazda prefers the biofuel solution. The Hiroshima builder hired this weekend a diesel-powered racing Demio (Mazda2) 1.5 l Skyactiv-D modified to accommodate biodiesel.

As for Toyota and Subaru, already united with the electric duo bZ4X and Solterra, they will also opt for synthetic fuel. Still within the Super Taikyu Series endurance races, the two brands want to use it on the new Subaru BRZ and Toyota GR86 coupes in 2022.

It remains to be proven that the hydrogen will be green. If that of the racing Toyota derives from biogas, Kawasaki still admits to being based on an Australian lignite-based production. Not very “green” all that.
