as a measure of electric energy use in spite of the fact that this is the unit used in their monthly electric bills. Instead, participants favored a miles per gallon of gasoline equivalent, MPGe, as the metric to compare with the familiar miles per gallon used for gasoline vehicles. The research also concluded that the kW-hrs per 100 miles metric was more confusing to focus group participants compared to miles per kW-hr. Based on these results, EPA decided to use the following fuel economy and fuel consumption metrics on the redesigned labels: MPG (city and highway, and combined); MPGe (city and highway, and combined); Gallons per 100 miles; kW-hrs per 100 miles.[

cars and trucks were consulted for 60 days with the public in 2010, and both included miles per gallon equivalent and kW-hrs per 100 miles as the fuel economy metrics for plug-in cars, but in one option MPGe and annual electricity cost are the two most prominent metrics. One of the design options had a letter grading system from A to D and the rating would have compared a given vehicle’s fuel economy and air pollution to those of the entire fleet of new cars. The letter grade system was opposed by carmakers and rejected after the public consultation.
