In a joint conference held in Japan on May 28, Toyota, Mazda, and Subaru announced their plans to develop new internal combustion engines. The three automakers aim to improve the efficiency and compatibility of these engines with carbon-neutral fuels such as liquid hydrogen, biofuel, and synthetic fuel.
Toyota is focusing on new inline-four engines for future models. Mazda is exploring rotary engines for electric vehicle applications, which currently serve as generators. Subaru plans to enhance the horizontally opposed boxer engine.
Mazda displayed single- and dual-rotor engines at the conference, while Toyota showcased a pair of inline-four engines: a 1.5-liter unit and a larger 2.0-liter engine. Subaru brought a next-generation hybrid system combined with a camouflaged Crosstrek prototype.
The trio intends to integrate motors, batteries, and other electric drive units into these next-gen ICEs to deliver better performance and lower hoods for improved aerodynamics. The new engines will enable future models to have more design freedom while maintaining or even improving efficiency.
Toyota's CEO Koji Sato expressed hope that these engines would contribute to the world's transition towards carbon neutrality.
