For instance, Toyota Motor Corp. is improving hybrid engine technology, integrating efficient combustion engines with an electric motor to lower emissions while providing increased performance. Likewise, Volkswagen AG is developing modular engine platforms, and with options for adaptability to traditional fuel systems and electrified powertrains, is allowing for scalability across various segments of vehicles.

At the same time, BMW AG is working on further refinement of TwinPower Turbo technologies for efficiency and the delivery of increased power, embracing Earth Dreams Technology to enhance fuel efficiency and minimize its carbon footprint. All these developments guarantee that the industry is committed to producing engines with sustainability goals in mind without compromising performance and reliability.

Recent Developments

• In June 2025, Nissan introduced third third-generation e-POWER technology in Europe. Combined with improvements to engine calibration and sound insulation, the system reduces both noise and vibration underload. Overall, power is up by 11kW, at a maximum of 151kW. The fixed battery capacity of 2.1kWh. Additionally, regarding engine efficiency, it has moved to 0W16 lubricating oil, providing reduced internal friction.

• In May 2024, Subaru Corp., Toyota Motor Corp., and Mazda Motor Corp. (Mazda) each collaborated to develop new engines tailored to electrification and the pursuit of carbon neutrality. These engine companies aim to optimize integration with motors, batteries, and other electric drive units. By transitioning to more compact engines and by developing transitional engine technologies that support various carbon-neutral (CN) fuels, the impact of ICEs was decarbonized via innovative vehicle packaging.
