Currently reading: Toyota, Mazda, Subaru to “revolutionise” engines in ICE commitment
Japanese allies will “aim to optimise” combustion engines with electric motors and batteries, alternative fuels

MazdaSubaru and Toyota have committed to developing new engines in an attempt to decarbonise ICE cars, with a renewed focus on hybridisation and carbon-neutral fuels.

The allied Japanese brands jointly confirmed they would “aim to optimise” engines with electric motors, electric drive units and batteries, which goes against the trend of brands transforming entirely to EV-only line-ups. 

The trio said the decision was driven by “a deep understanding of their customers’ diverse lifestyles” as well as a belief of a future for ICE.

In their pursuit of carbon neutrality, they will also “revolutionise” engine packaging.

Compact engines, they said, will mean smaller vehicles and in turn better aerodynamics and fuel efficiency, while complying with increasingly stringent emissions regulations. 

The engines won’t be purely petrol-fuelled, either, as Mazda, Subaru and Toyota will also major on alternative fuels, such as biofuels, synthetic e-fuels and hydrogen.

“We will continue to offer customers exciting cars by honing internal combustion engines for the electrification era and expanding the multi-pathway possibilities for achieving carbon neutrality,” said Mazda president and CEO Masahiro Moro.

Subaru president and CEO Atsushi Osaki suggested the target of carbon neutrality was one that should be a primary focus in Japan, adding: “As we continue to refine electrification technology, we will also enhance our horizontally opposed engines with an aim to use carbon-neutral fuels in the future.

Toyota president and CEO Koji Sato said the decision would offer customers “diverse options” so they could drive carbon neutrally and described the three brand’s plans as “friendly competition”.

“In order to provide our customers with diverse options to achieve carbon neutrality, it is necessary to take on the challenge of evolving engines that are in tune with the energy environment of the future,” Sato said. 

Despite this announcement, Toyota is still heavily backing EVs. It's aiming to launch at least 30 new electric models by 2030, with the goal of selling 3.5 million EVs around the world each year. 

Ten of those will be a part of the brand’s European line-up by 2025, including the Urban Crossover concept that was revealed at the end of 2023.

Smaller cars, such as the Aygo, won't switch to electric power, as battery costs have been deemed too expensive. 

Meanwhile, Mazda is targeting a spend of £8.7bn on electrifying its model line-up by 2028 and Subaru plans to have an eight-strong EV line-up by then.

Sounds like a shit recipe full of dull, naturally aspirated, CVT powered shit boxes.

Your comment proves that you are Nissan marketing manager, Mr. Marcono Shito.

Hydrogen - delusional, synthetic fuels/bio-fuels doubly delusional. Why would Toyota be doing this if it has "game changing solid state batteries with unbelieviable range, ready to very probably".

You make it sound  like EV power is the only answer, talk about head in Sand.

Well if you stick your head into the sand you will find Toyota, Mazda and Subaru in residence. Grey hydrogen is more polluting than burning natural gas from which it is derived. Blue hydrogen requires carbon capture on a huge scale, not feasible and very expensive, green hydrogen only delivers 25% of the electric energy it consumsumes and is impossibly expensive. Synthetic fuels start with green hydrogen and carbon capture, stupidity squared! Fine for F1 and MotoGP, but not the real world.

Batteries on the other hand are getting cheaper, more energy dense, faster charging and safer with every (rapid) iteration.

No, he's stating Hydrogen isn't a solution for cars.

Sounds like a good idea, Mazda with their Rotary range extenders, Toyota with the knowhow of hybrid integration with ICE & Subaru with their Boxer engines which, I presume, would be great for packaging benefits in the engine bay.

Pure EV's are the way forward long term, but hybrids & REX EV's are sure to be needed for long commutes/deliveries for the time being.
