In today’s automotive industry, there is a growing trend towards decarbonization and the adoption of electric vehicles, but not all automakers are fully committing to this path. Some manufacturers, like Toyota, Mazda, and Subaru, are working on innovative solutions to reduce emissions and improve fuel efficiency without completely abandoning traditional internal combustion engines (ICEs).
### Saving the Manuals and ICEs
Some automakers are working on preserving the manual transmission, while others are focused on rescuing the internal combustion engine. Toyota, Mazda, and Subaru recently held a joint conference to discuss their efforts to achieve decarbonization without fully transitioning to electric vehicles. Toyota is developing new smaller and more efficient engines, Mazda is exploring single- and two-rotor engines, and Subaru is working on a next-generation hybrid system for its horizontally opposed boxer engine.
### Next-generation Subaru Hybrid Boxer Engine
One of the key developments highlighted during the conference was Subaru’s next-generation hybrid boxer engine. This new system combines a combustion engine with an electric motor to improve fuel economy and packaging. The new layout allows for a more compact design, with the engine, hybrid system, transmission, and transfer case housed together, while also maintaining a mechanical connection between the ICE and the wheels. The power control unit is located in the engine bay, allowing for a larger fuel tank and increased range compared to previous hybrid models.
### Subaru High Performance X Future Concept
Subaru is also collaborating with Toyota and Mazda on carbon-neutral fuels and will be entering a WRX-based High Performance X Future Concept in the Super Taikyu racing series. Additionally, Mazda is reviving its rotary engine in a unique way by using it as a generator in the MX-30 crossover, rather than sending power directly to the wheels. Mazda is also exploring the possibility of a two-rotor engine for a new sports car, potentially a revival of the iconic RX7 model.
Overall, these efforts by automakers like Toyota, Mazda, and Subaru demonstrate a commitment to finding innovative solutions for reducing emissions and improving fuel efficiency, while still maintaining a connection to traditional internal combustion engines. By exploring new technologies and hybrid systems, these companies are paving the way for a future that combines the best of both worlds in terms of performance, efficiency, and environmental sustainability.
