Abstract: To confirm that it is true that new energy vehicles are better than traditional internal combustion engine vehicles to a certain extent at this stage, and the domestic promotion of new energy vehicles, especially pure electric vehicles, which is conducive to the development of the domestic automobile industry, this paper evaluates the energy consumption and pollutant emissions in the life cycle of traditional internal combustion engine vehicles, plug-in hybrid electric vehicles and pure electric vehicles by using the GREET software, combining with the life cycle assessment method and the “well to wheel (WTW)” system. From the perspectives of energy consumption, pollution emissions and driving costs, it is concluded that new energy vehicles are better than traditional internal combustion engine vehicles in terms of energy consumption, greenhouse gases, alternative pollutants and driving costs, and are inferior to traditional internal combustion engine vehicles in terms of acid rain pollutants and particulate pollutants. Through the comprehensive consideration, new energy vehicles are superior to traditional internal combustion engine vehicles.
