As the application of several energy saving technologies and the continuous tightening fuel consumption standards, the fuel consumption of China’s gasoline passenger cars is decreasing continuously. In this paper, the development of the standards related to fuel consumption was reviewed firstly, and the development of the fuel consumption for China’s gasoline passenger cars has been investigated based on the declared fuel consumption data of over 4800 vehicle models produced or imported in recent 5 years (2014-2018). Results showed that the average fuel consumption in 2018 decreased 6.4% compared to 2014, about 1.6% per year. In additions, the development of gasoline passenger cars with turbocharge engines and auto transmissions had a more significant effect on the fuel consumption reduction, and the annual decreasing rate reached 2.4% per year and 3.6% per year, respectively.

随着多项节能技术的应用和油耗标准的不断收紧，我国汽油乘用车油耗不断下降。本文首先回顾了油耗相关标准的发展情况，以近5年来生产或进口的4800余款车型的申报油耗数据为基础，对我国汽油乘用车油耗发展情况进行了调查。年（2014-2018）。结果显示，2018 年平均油耗较 2014 年下降 6.4%，约为每年 1.6%。此外，汽油乘用车涡轮增压发动机和汽车变速器的发展对油耗降低的影响更为显着，年降幅达到2%。
