US media select 20 thousand and 160 "power saving" models

Recently, the U.S. media selected 10 fuel-efficient vehicles, no accident, this list is still dominated by new energy vehicles. However, in order to be fair, new energy vehicles (EV, PHEV) are classified as ordinary fuel vehicles. According to the previous list, the Japanese hybrid version of ordinary fuel vehicles is an evergreen tree, but in the field of new energy, the Japanese system almost disappears...

In addition, in order to understand the readers, we first give a brief introduction to "MPGe" MPGe. In order to distinguish fuel economy between EV and PHEV/ordinary fuel vehicle, EPA adopted the method of energy equivalent calculation. The energy efficiency of EV was calculated by 33.7 degree electricity equivalent to 1 gallon of gasoline. The unit of "MPGe" was used to distinguish "MPG" of ordinary gasoline vehicle. The higher the unit value, the better the unit value. The fuel consumption we used for 100 kilometers is just the opposite.

The following is the top ten list of new energy vehicles:


From this list, we can see that it is not pure electric fuel-saving, which may not be understood by many readers. Pure electric power is no better than BMW I3 (with engine). This is because EPA converts power consumption to fuel consumption in an "equivalent" unit (33.7 kW is equivalent to 1 gallon of gasoline). Therefore, after conversion, the first-time power consumption is equal to 1 gallon of gasoline. Or the farther a gallon of gasoline runs, the higher the ranking. It's much like Honda's energy-saving car race. This algorithm is closer to the facts. It's totally different from the domestic fuel consumption algorithm. For plug-in hybrid, domestic manufacturers claim that the fuel consumption is less than 2 liters, but the actual estimate of the car owner is 89 liters.
