In a landmark collaboration, Subaru Corporation, Toyota Motor Corporation, and Mazda Motor Corporation have committed to the development of innovative engines designed for electrification and carbon neutrality. This joint effort aims to integrate motors, batteries, and electric drive units more efficiently while transforming vehicle packaging with compact, high-performance engines compatible with various carbon-neutral (CN) fuels.
Leaders from each company—Atsushi Osaki (Subaru), Koji Sato (Toyota), and Masahiro Moro (Mazda)—expressed a shared vision for sustainable automotive technology. “Achieving a carbon-neutral society is a challenge that must be undertaken by all of Japan’s industries and society as a whole,” stated Osaki, emphasizing the collaborative spirit driving the initiative.
The new engines will support a multi-pathway approach to decarbonization, offering compatibility with e-fuels, biofuels, and liquid hydrogen. This strategy not only targets emissions reductions but also ensures the sustainability of supply chains and jobs linked to internal combustion engine (ICE) production.
Under extreme conditions, such as racing, the companies have been testing vehicles powered by liquid hydrogen and CN fuels to broaden powertrain and fuel options. This rigorous testing has clarified the critical role future engines will play in achieving carbon neutrality.
“Refining engine technologies through friendly competition will enable us to provide our customers with diverse options to achieve carbon neutrality,” remarked Toyota’s Sato. Moro of Mazda added, “We will continue to hone internal combustion engines for the electrification era, expanding possibilities for achieving carbon neutrality.”
The engines’ compact design will allow for lower hoods, improving vehicle aerodynamics and design possibilities while enhancing fuel efficiency. Compliance with stringent emissions regulations will also be a key focus in their development.
This groundbreaking collaboration among Subaru, Toyota, and Mazda highlights their commitment to pioneering sustainable excellence in Japanese car manufacturing. By pooling their expertise and passion, these automotive giants are set to revolutionize the future of engine technology and drive the global transition to carbon neutrality.
