Four rationales for Toyota, Mazda, and Subaru’s increased reliance on internal combustion engines

Together with the CEOs of Mazda and Subaru, two smaller companies in which Toyota has minority shares, Toyota CEO Koji Sato presented the push on stage.

Tokyo — Even in the era of electric vehicles, Toyota Motor Corp. and its Japanese automakers' allies Mazda and Subaru are putting more effort into developing the next generation of small, efficient, and powerful engines that they believe will become formidable weapons in the fight against carbon emissions.

Toyota is spearheading this effort, referring to the plan as "Engine Reborn."

On May 28, Toyota CEO Koji Sato discussed the initiative on stage with the CEOs of Subaru Corp. and Mazda Motor Corp., two smaller companies in whom Toyota has minority ownership shares.

Here's why the corporations believe that improved fuel-burning engines still have a lot of potential.

Four rationales for Toyota, Mazda, and Subaru's increased reliance on internal combustion engines

Emissions from the life cycle

When operating, full electric vehicles that are solely reliant on batteries produce no emissions.

However, Toyota stated that an EV's total environmental impact should also take into account the electricity's initial energy source and manufacturing emissions. That would monitor emissions for the duration of the car's life. According to Toyota, EVs and hybrid cars with internal combustion engines are comparable in that regard.

This is due to the possibility that EVs' larger batteries may need additional coal-burning power stations to be recharged. Additionally, producing EVs and their batteries can result in higher carbon emissions. As a result, while hybrid cars with engines are running, they produce more pollution than they do in terms of production and energy.

Improved outcomes

It is anticipated that the new engines being developed by Subaru, Mazda, and Toyota will outperform their predecessors in terms of power and cleanliness. This will enable them to leave less of a carbon footprint while preserving the vintage-inspired driving experience.

Additionally, the engines will be less in size. Better linkage with electrified hybrid technologies, including batteries and electric motors, will be made possible by this. When paired with hybrid systems, these engines will reduce carbon emissions even more. According to Toyota, the power output of the future 1.5-liter turbocharged four-cylinder will be equal to that of a conventional 2.5-liter normally aspirated engine. In comparison to the 2.0-liter turbo of today, a new 2.0-liter turbo will outperform a 2.4-liter turbo and gain higher fuel economy.

Novel fuels

As long as hybrid systems are attached to gasoline-burning engines, carbon emissions will always occur, regardless of the size of the electric motor and battery. However, Team Toyota sees internal combustion engines in the future that run on a variety of carbon-neutral fuels, including biofuel, synthetic e-fuel, and eventually clean-burning hydrogen.

Similar to gasoline, these liquid fuels offer benefits in terms of energy density, storage, and transportation. Furthermore, if they come to pass, internal combustion might become nearly carbon neutral. On May 27, Toyota declared that it would be collaborating with other businesses to research the potential introduction and spread of these fuels in Japan by 2030.

Chic styles

EV drivetrains are frequently hailed by designers as creating new possibilities for car packing. Expansive cabins, short overhangs, and level flooring are made possible by the comparatively smaller electric motors of EVs, their flat batteries, and their reliance on flexible electric wires rather than hard propeller shafts.

According to Toyota, Mazda, and Subaru, their available smaller engines allow them to get comparable results. For example, Toyota intends to incorporate these engines into the svelte, wedge-shaped designs it is developing for its upcoming line of fully electric vehicles. Its future 1.5-liter turbo has a volume 20% less and a height 15% less than that of its turbocharged predecessor. Mazda also believes that smaller rotary engines work better in hybrid systems.
