Toyota recently announced plans to introduce lean compact engines that will run on green fuels like hydrogen and bioethanol, or be paired with electric motors in hybrids. The goal is to achieve carbon neutrality in the electrification era, with the electric motor becoming the main driving power in future hybrids. Domestic allies Subaru Corp. and Mazda Motor Corp. are also developing ecological engines to meet upcoming emissions standards. While the auto industry is leaning towards Battery Electric Vehicles, Toyota emphasizes the need for a variety of solutions to meet different energy supply conditions and customer preferences. Experts highlight the importance of electric vehicles for emission reduction but acknowledge challenges such as emissions from battery production. The journey towards carbon neutrality is seen as a long-term effort that involves various uncertainties in research, development, and market conditions.
