How 5(+2) Japanese manufacturers are trying to save ICE

Of course, this doesn't mean they are negating the carbon neutrality

On November 13th, 2021, at the Super Taikyu Race, the 5 companies - Toyota, Subaru, Yamaha, Kawasaki, and Mazda - said that they will be expanding fuel options using ICE technology.

Specifically, they will be continuing to develop alternative fuels and engines to continue the use of internal combustion engines while pursuing to achieve carbon neutrality.

1. Participating in races using carbon-neutral fuels

As an example, Mazda will be creating 'MAZDA SPIRIT RACING Bio concept DEMIO' (Mazda 2) with a 1.5L Skyactiv-D Diesel engine that runs on 100% biomass-derived diesel fuel. Mazda (along with Toyota and Subaru) said that they will be expanding the use of this engine. Toyota and Subaru will be using biomass-derived synthetic fuel for Subaru BRZ and GR86-based vehicles for the next year's Super Taikyu Series.

The biomass involves cooking oil and fats - which means it won't involve human food supplies. This fuel will also not require modifications and/or new infrastructure for implementation.

2. Exploring the use of hydrogen engines in two-wheeled and other vehicles



With Hydrogen transported by Kawasaki Heavy Industries Suiso Frontier (first-in-world, purpose-built liquefied hydrogen carrier) and its own hydrogen-fueled gas turbine power generation technology, Kawasaki will be creating land, sea, and air mobility applications - aircraft, ships, and motorbikes (and other two-wheeled vehicles). Yamaha is developing hydrogen engine technology for use in bikes and four-wheeled recreational vehicles (such as quad bikes) as well.

As the two companies share a goal, they are considering joint development of a hydrogen engine for the two-wheeled vehicles. For this joint, Honda and Suzuki are also planning to join in the future.

3. Continuing to race using hydrogen engines

Toyota has been participating in race events with a hydrogen racecar - Corolla Sport H2 Concept - such as the Fuji Super TEC 24 Hours Race, the Super Taikyu Race in Autopolis, and the SUZUKA S-TAI. Toyota is continuing to develop Hydrogen racecars with the help of Yamaha (performance, engine, race testing) and Denso (direct-injection injectors and spark plugs).

Toyota will be collaborating with many partners, such as Fukuoka City, Commercial Japan Partnership Technologies (CJPT), with its own technologies for the production, transportation, and usage of this hydrogen fuel.

  • Japan is doing a really good job. I have no problem with EVs, but an all-EV future (especially in a few years) just seems too ambitious (or if I'm being honest, stupid) to me.

  • The problem is only Japan is on board with hydrogen. Pretty much every other manufacturer has set their eyes on BEVs, so their really isn't any going ng back. Personally, I think Hydrogen cars will die out and BEVs will be the final solution. Don't forget that their are different kinds of BEVs. (Solid State, Lithium Ion, Supercapacitater, etc...)

    • BEVs won't be the solution, neither will FCEV or ICE. All will produce emissions in production (digging up a 1cm x 1cm piece of turf with a shovel when gardening releases harmful emissions into the atmosphere, this plus the fact that the...

  • Hydrogen ICE for the win!

    • There is no such thing. Hydrogen cars have an electric motor.

    • There is such a thing. Yes, FCEVs are typically fuelled by a fuel cell filled with hydrogen. Hydrogen also works in combustion engines with modifications.

  • there are a million reasons why an all EV future will not work. we must do everything we can to encourage the use of e fuels

  • Kawasaki is the only non Toyota Party in this group.

    Toyota have the largest single share in Subaru and the largest single share in Mazda outside its traditional shareholder group. They also have major collaboration with Mazda and a long term relationship with Yamaha.

    So none of this surprises me from a collaboration view point.

    But they truly need others outside of Japan onboard!
