Miles per gallon electric equivalent or MPGe is the EPA-formulated efficiency metric to compare to liquid fuel vehicles. It gives a clear indicator of how much more efficient an electric vehicle is over a liquid or gas operated vehicle such as gasoline or diesel. Here, I provide a list of the most efficient EVs on the market, and they hover around the 120-140 MPGe. An efficient gas vehicle may get you about 35 MPG. So, we’re talking magnitudes more efficient. An electric motor in an EV commonly transforms about 80% of energy into torque, while an efficient gasoline engine normally turns about 40% of energy into torque. Also, the EPA has calculated the efficiency of EVs for the energy used every 100 miles of travel in kilowatt hour KWH. So, the lower KWH per 100 miles; the more efficient the EV. The range is another very important metric in an EV. ...
