Here is an intriguing infographic from the folks at Visual Capitalist that shows information about some of the most fuel efficient cars from throughout history including the number of miles per gallon (MPG) or the miles per gallon of gasoline-equivalent (MPGe)... Read More »
It's already not straight forward to calculate the MPG or L/100km, because it's highly dependent on driving and weather conditions and OEMs use this confusion to fudge the numbers all the time.
I suppose the MPGe, on top of all that depends also on the cost of electricity ?
However, because EVs do not use fuel, the EPA had to develop a new system called MPGe (miles per gallon of gasoline-equivalent).
This new metric gives us the ability to compare the efficiency of EVs with traditional gas-powered cars. An underlying assumption of MPGe is that 33.7 kilowatt-hours (kWh) of electricity is comparable to the energy content of a gallon of fuel.
