Toyota’s Chief Technology Officer, Hiroki Nakajima, recently unveiled details about the company’s new four-cylinder internal combustion engines (ICEs) that are set to revolutionize the automotive industry. These new 1.5- and 2.0-liter engines are said to be a “game-changer solution” and will be completely different from existing ICEs. Toyota’s engineers have been working on improving engine heat efficiency through the development of hydrogen cars like the Mirai, which has provided valuable insights for the new engines.
One key aspect of the new engines is their shorter piston stroke, which was a challenging task to accomplish but will enable improved vehicle packaging and efficiency by optimizing airflow. While these new engines will be smaller in size, the torque lost will be compensated by the instant response of an electric motor, as they are primarily being developed for use in hybrid vehicles. Toyota plans to introduce cars with these new engines around 2027, and they will be capable of running on various fuels including fossil fuels, biofuel, hydrogen, and synthetic fuel.
In contrast to Toyota’s strategy, Nissan has recently announced that it has halted development on ICEs and is focusing solely on electric vehicles (EVs). Nissan plans to use range-extending gas engines as a temporary solution while transitioning to full EVs. This shift in strategy reflects the evolving landscape of the automotive industry towards electrification and sustainable mobility solutions.
Overall, Toyota’s innovative approach to developing new ICEs underscores the company’s commitment to advancing technology and sustainability in the automotive sector. The new engines hold promise for enhancing efficiency, performance, and flexibility in powertrain design, demonstrating Toyota’s dedication to staying at the forefront of automotive innovation.
