Fuel economy ratings and driving range figures are based on EPA estimates for new vehicles, and actual mileage and range may vary depending on factors such as driving conditions, vehicle maintenance, fuel quality, driving habits, and modifications. For used vehicles, the EPA estimates were generated when the vehicle was new, and actual fuel economy may differ more significantly due to factors like age, maintenance history, and vehicle condition. Therefore, EPA estimates should be used as a general guide for comparison purposes only and not as a guarantee of actual fuel economy or driving range, especially when considering used vehicles.
