A major factor in comparing potential new car options today is assessing overall efficiency, known as a vehicle’s average miles per gallon, or MPG rating. For vehicles that utilize a plug-in hybrid system (also known as PHEVs) or an all-electric powertrain, a different grade of average energy efficiency can also apply, known as MPGe. For new car buyers, there may be some confusion as to what sets apart MPGe from normal MPG ratings, and why it matters for vehicles like the Tesla Cybertruck. Along with the MPGe metric’s meaning, we’ll explain why it may not be the best way to measure an EV’s efficiency.
