Recently, US media selected the top ten most fuel-efficient vehicle models. Unsurprisingly, this list is still dominated by new energy vehicles. However, for the sake of fairness, new energy vehicles (EV, PHEV) have been separated from conventional fuel vehicles. According to previous lists, Japanese hybrid versions have always been evergreens in the conventional fuel vehicle sector, but in the new energy vehicle sector, Japanese models have almost disappeared...
In addition, for readers' better understanding, we first give a brief introduction to "MPGe". To easily distinguish the fuel economy of EVs from that of PHEVs/conventional fuel vehicles, the US EPA (United States Environmental Protection Agency) adopted an energy equivalent calculation method: it equates 33.7 kWh of electricity to 1 gallon of gasoline to convert and calculate the energy efficiency of EVs, uses "MPGe" as the unit to distinguish it from "MPG" used for conventional gasoline vehicles. The higher the value of this unit, the better the efficiency, which is exactly the opposite of the commonly used 100-kilometer fuel consumption value we use.
The following is the top 10 list of new energy vehicles:
It can be seen from this list that it is not the case that all pure electric vehicles are fuel-efficient. Many readers may not understand why pure electric vehicles are even outperformed by the BMW i3, a range-extended model (with an engine). This is because the EPA converted the electricity consumption and fuel consumption into an "equivalent" unit (33.7 kWh of electricity equals 1 gallon of gasoline). Therefore, after conversion, the farther a vehicle can travel per kWh of electricity or per gallon of gasoline, the higher its ranking. This is very similar to Honda's fuel efficiency competition, and this calculation method is closer to the actual situation, which is different from the fuel consumption calculation method adopted in China. For plug-in hybrid vehicles, domestic manufacturers claim that their fuel consumption is within 2 liters per 100 kilometers, but the actual fuel consumption that owners get is probably eight to nine liters per 100 kilometers.
