U.S. DOT and EPA Finalize New Fuel Economy and Environmental Labels, Including Those for Electric Vehicles

July 8, 2011

The U.S. Department of Transportation's (DOT) National Highway Traffic Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) finalized regulations for new vehicle labels that will provide more comprehensive fuel efficiency and environmental impact information.

Specifically, the new labels will include estimates for fuel cost savings over a five year period as compared to the average new vehicle, as well as smog and greenhouse gas emissions comparison ratings.

Starting with Model Year 2013 vehicles, the new labels must be affixed to all new passenger cars and trucks, including electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). The labels will include new ways to compare the energy use and costs between these advanced vehicles and conventional gasoline-powered vehicles. The EV labels will include fuel economy estimates in kilowatt-hours per 100 miles and in miles per gallon (MPG) of gasoline equivalent (electricity consumption translated into MPG on an energy-equivalent basis), as well as how far the EV can travel on a fully charged battery and how long it takes to charge the battery. The PHEV labels will include fuel economy information for each relevant operating mode, including all-electric, blended, and gasoline-only.
