Different measurement cycles are utilized to approximate the particular general performance on the automobile. The energy in fuel is needed to overcome several losses (wind resistance, tire drag, and Other individuals) in propelling the car, and in furnishing energy to auto methods like ignition or air-con. Various actions might be taken to scale back losses at Each individual with the conversions involving chemical Electrical power in fuel and kinetic energy on the auto. Driver behavior can impact fuel economy; maneuvers which include unexpected acceleration and significant braking squander energy.
