We all want to get the most from our gas tanks, especially when fuel prices rise. However, a closer look at different driving scenarios showed significant variation based on changes in speed, acceleration and distance.
AAA worked with the Automotive Research Center (ARC) of the Automobile Club of Southern California to test select vehicles. Using a series of simulated driving scenarios, researchers determined the accuracy of the vehicles’ miles-to-empty displays. Different driving situations included sitting in traffic, typical in-town driving and highway driving.
Results suggested that different vehicles responded differently to changes in driving and that driving style and conditions can affect the accuracy of their miles-to-empty systems. While testing revealed irregularities, researchers say the fuel economy display can still be a helpful tool. The information it shows can help you see how your driving habits influence fuel economy. It’s recommended that drivers reset their vehicle’s trip data after filling up the gas tank and then observe how the fuel economy display changes with driving conditions.
