Improved fuel economy is one of the start-stop technology’s main advantages. Depending on the vehicle, idling can take up to a half gallon of gasoline every hour, according to the U.S. Department of Energy. By reducing the amount of time that an engine idles, start-stop technology can help to improve fuel efficiency and reduce fuel consumption.
According to a European Commission research, start-stop technology can save fuel consumption in urban driving situations by up to 8%. This can translate into significant savings for drivers over the life of their vehicle, particularly in areas with heavy traffic or frequent stop-and-go driving.
