I consider it is. While I wholeheartedly think it is important to have an efficiency metric on which to compare vehicles, I think MPGe is an abomination foisted on consumers by the ICE incumbents (car and oil companies) to confound efficiency discussions and to reduce perception of efficiency gained by making EVs for manufacturers. I am not debating whether distance or energy should be used as numerators or denominators (litres/100km etc is just the same in my mind) I am talking about reducing kWh to an equivalent "gallons/litres of gas" without incorporating into it the political, monetary, supply chain, and transport & distribution station costs of getting that gallon of oil into the car, and the environmental, carbon capture, etc costs that are externalized in that unit. It especially annoys me to see websites to buy/sell cars putting electric car MPGe under the same label as MPG, so you can compare a 40 mpg Honda Civic with a 89 mpg Tesla Model S. Then a website calculator asks how many miles you drive and with your zipcode calculates the $/gal and tells you the cost to drive the car over 5 years. And mentally, who will pay attention to the 'e' - consumers will mentally estimate a 90 MPGe car to be only 3 times as efficient as a 30 mpg car. I'm trying to see if there is something I missed on either side of the argument - do you consider MPGe to a useful unit for comparing car efficiency, or a distractive/destructive one - and why?
