IMPORTANT REMINDER: EPA's fuel economy estimates are designed to allow consumers to comparison shop. Your fuel economy will almost certainly vary from EPA's fuel economy rating. This is based on a number of factors, such as weather, road conditions, your driving and maintenance habits, and your use of air conditioning. For more information on how your fuel economy can vary, or tips to improve your fuel economy, please visit Your MPG Will Vary and Gas Mileage Tips on www.fueleconomy.gov.
Beginning with 2008 models, all fuel economy estimates based on new test methods, which EPA finalized in December 2006. The new methods better account for actual driving conditions that can lower fuel economy, such as high speed, aggressive driving, use of air conditioning, and cold temperature operation. The new estimates will give drivers a more accurate estimate of the fuel economy they are likely to achieve on the road. Because of the new methods, the estimates for most 2008 models will be lower than their 2007 counterparts. To aid consumers shopping for new cars, EPA has also redesigned the fuel economy window sticker posted on all new cars and light trucks to be easier to read and understand.
EPA has finalized new methods used to determine the City and Highway miles per gallon (MPG) estimates that appear on the window stickers of new cars and trucks. Beginning with 2008 models, all fuel economy estimates are based on these new methods. Although no single test can ever account for the wide variety of driving conditions and styles, the new methods will bring the MPG estimates closer to the fuel economy consumers actually achieve on the road by taking into account conditions such as higher speeds, agressive driving, cold temperature operation and use of air conditioning. The new estimates will give drivers a more accurate estimate of the fuel economy they are likely to achieve on the road. Because of the new methods, the estimates for most 2008 models will be lower than their 2007 counterparts.

EPA is responsible for providing fuel economy (gas mileage) data that is posted on the window stickers of new vehicles. These fuel economy estimates help consumers compare the fuel economy of different vehicles. Fuel economy data is also used by:
- the U.S. Department of Energy (DOE) to publish the annual Fuel Economy Guide
- the U.S. Department of Transportation (DOT) to administer the Corporate Average Fuel Economy (CAFE) program, and
- the Internal Revenue Service (IRS) to collect gas guzzler taxes.
