Nissan Motor has revealed that it has reached a breakthrough in achieving a 50% thermal efficiency with its in-development e-POWER hybrid technology.
This breakthrough could lead to a further reduction of car CO2 emissions.
This new thermal efficiency level would improve fuel consumption by 25% over the 40% thermal efficiency level in the upcoming e-POWER engine, Nissan said.
Nissan did not disclose when the e-POWER technology with 50% thermal efficiency would be launched.
The e-POWER, first introduced in Japan in 2016, uses a gasoline engine to charge a battery that powers the vehicle.
The automaker said last month that all of its new models in key markets would be electrified by the early 2030s to achieve carbon neutrality by 2050.
Nissan has also said it expects sales of more than one million electrified vehicles per year by the end of fiscal 2023.
