Features of the new engine

Optimal combination with motor and battery
Innovation in car packaging through miniaturization of engines
Compatible with various carbon neutral fuels (CN fuels)
High efficiency/high output
Responding to strict exhaust regulations

Toyota’s high efficiency engine

New engines include a 1.5L 4-cylinder engine. It is said that the car’s packaging has been revolutionized by making the engine more compact, resulting in higher efficiency and higher output, while also improving fuel efficiency.

Furthermore, the new 1.5L 4-cylinder turbo engine has almost the same engine output compared to a conventional 2.5L engine and a 1.5L turbo engine, and is said to be able to pass strict emission regulations.

Compared to the current 2.4L engine, the new 2.0L 4-cylinder engine is said to have almost the same engine output compared to the current 2.4L engine, and is said to be able to pass strict emission regulations.

In the electrification era, instead of the engine assisting the motor, the motor will play a leading role, and the engine will play a supporting role. This allows the engine output to be reduced and the engine stroke to be shortened. As a result, the height of the engine itself can be lowered.

mazda 2 rotor rotary

Achieves high output despite being small and lightweight. Currently used as a generator. Compatible with various carbon neutral fuels (CN fuels).

The new-age electrification unit “ROTARY-EV SYSTEM CONCEPT (ONE ROTOR)” is a combination of a horizontally mounted single rotor for power generation and a new electric drive unit. More compact than MX-30 Rotary-EV.

“ROTARY-EV SYSTEM CONCEPT (TOW ROTOR)” Vertical installation, combination of two rotors for power generation and a new electric drive unit. A unit that achieves proportions with a low center of gravity. The company is considering using it in sports cars and other vehicles.

Subaru’s new hybrid system

Subaru’s new hybrid system employs the series hybrid system “THS (TOYOTA Hybrid System)”. It is said that the horizontally opposed engine will continue to be part of Subaru’s identity.

Purpose of the new engine

Optimal performance is achieved not by the engine alone, but by working with the electric unit.
Improved design, aerodynamic performance, and fuel efficiency by downsizing the engine hood
Achieves carbon neutrality by supporting various CN fuels such as e-fuel, biofuel, and liquid hydrogen.

Comments from the CEOs of the three companies

The CEOs of each company expressed their determination to develop new engines to achieve carbon neutrality, and stated that they will continue to work together to hone technology and energize Japan’s automobile industry. The three companies will continue to balance competition and co-creation while aiming to achieve carbon neutrality and building the future of Japan’s automobile industry.

Toyota President and CEO Tsuneharu Sato

In order to provide customers with a variety of options that contribute to carbon neutrality, we will continue to take on the challenge of evolving engines that are compatible with the future energy environment. As three companies that share the same aspirations, we will work hard to improve our skills through friendly competition.

SUBARU President and CEO Atsushi Osaki

Achieving a carbon-neutral society is an issue that must be addressed by Japanese industry and society as a whole. In addition to refining vehicle electrification technology, we will also further refine horizontally opposed engines themselves in order to utilize carbon-neutral fuel. We will continue to invigorate Japan’s car manufacturing industry as a group of three companies with the same aspirations.

Mazda President and CEO Katsuhiro Kego

We will continue to refine the internal combustion engine in the age of electrification, expand the possibility of achieving carbon neutrality through multi-pathways, and continue to provide exciting cars to our customers. We will take on the challenge of co-creation and competition to develop the rotary engine, which is compatible with electrification and carbon-neutral fuels, as a technology that can widely contribute to society.

A word from the editorial department

It was announced that each company will continue to develop their own “signature” powertrains, including Subaru’s boxer engine, Toyota’s inline four-cylinder engine, and Mazda’s rotary engine. It is hoped that this will allow each manufacturer to use the right engine in the right place, and that new models will be created through collaboration between the three companies.

In particular, I’m really looking forward to the Crosstrek, which will be released in the fall of 2024, as it will be the first model to use the engine announced this time.

High efficiency and high output
Compliance with strict emission regulations

Toyota’s highly efficient engine

The new engines unveiled include a 1.5L 4-cylinder engine. The smaller engine size will revolutionize the car’s packaging, while improving fuel efficiency and power output.

Furthermore, in the case of the new 1.5L 4-cylinder turbo engine, the engine output is almost the same when compared to the conventional 2.5L engine and 1.5L turbo engine, and it is said to be able to meet strict emission regulations.

The new 2.0L 4-cylinder engine is said to have almost the same engine output as the current 2.4L engine, which is also smaller in size, and is able to meet strict emission regulations.

In the age of electrification, the engine will no longer assist the motor, but rather the motor will play the main role and the engine will play a supporting role.
