| 06-9749 | Fuel Economy Labeling of Motor Vehicles: Revisions To Improve Calculation of Fuel Economy Estimates | Rule | The Environmental Protection Agency (EPA) is finalizing changes to the methods used to calculate the fuel economy estimates that are posted on window stickers of all new cars and light trucks sold in the United States. This final rule will greatly improve the EPA fuel economy estimates to more accurately inform consumers about the fuel economy they can expect to achieve in the real world. The new test methods take into account several important factors that affect fuel economy in the real world, but are missing from the existing fuel economy tests. Key among these factors are high speeds, aggressive accelerations and decelerations, the use of air conditioning, and operation in cold temperatures. Under the new methods, the city miles per gallon (mpg) estimates for the manufacturers of most vehicles will drop by about 12 percent on average relative to today's estimates, and city mpg estimates for some vehicles will drop by as much as 30 percent. The highway mpg estimates for most vehicles will drop on average by about 8 percent, with some estimates dropping by as much as 25 percent relative to today's estimates. These changes will take effect starting with 2008 model year vehicles, available at dealers in 2007. We also are adopting a new fuel economy label design with a new look and updated information that should be more useful to prospective car buyers. The new label features more prominent fuel cost information, an easy-to-use graphic for comparing the fuel economy of different vehicles, clearer text, and a Web site address for more information. Manufacturers will be phasing in the new design during the 2008 model year. Finally, for the first time we are requiring fuel economy labeling of certain passenger vehicles between 8,500 and 10,000 lbs gross vehicle weight rating. Because of the Department of Transportation's recent regulation that brings medium-duty passenger vehicles into the Corporate Average Fuel Economy program starting in 2011, EPA is now statutorily obligated to include these vehicles in the fuel economy labeling program. Medium-duty passenger vehicles are a subset of vehicles between 8,500 and 10,000 lbs gross vehicle weight that includes large sport utility vehicles and vans, but not pickup trucks. Vehicle manufacturers are required to post fuel economy labels on medium-duty passenger vehicles beginning with the 2011 model year. | 2006-12-27 | 2006 | 12 | https://www.federalregister.gov/documents/2006/12/27/06-9749/fuel-economy-labeling-of-motor-vehicles-revisions-to-improve-calculation-of-fuel-economy-estimates | https://www.govinfo.gov/content/pkg/FR-2006-12-27/pdf/06-9749.pdf | Environmental Protection Agency | 145 | The Environmental Protection Agency (EPA) is finalizing changes to the methods used to calculate the fuel economy estimates that are posted on window stickers of all new cars and light trucks sold in the United States.
