Because used vehicle sales outnumber new vehicle sales by about three to one, a new tool has been developed that allows those selling used vehicles to produce a fuel economy label for the vehicle. The labels are optional and can be printed and affixed directly on a vehicle or downloaded in electronic format for online advertising. All labels come with a QR code that allows consumers to scan the label with a smart phone for additional vehicle information directly from the Fuel Economy Website. It is noted on the label that the mileage and CO2 estimates are for the vehicle when new, and that factors such as vehicle modifications and maintenance can affect fuel economy. However, if a vehicle has not been modified and has been properly maintained, its fuel economy should not vary significantly from when it was new.
