WASHINGTON -- Consumers shopping for new cars would be able to compare fuel economy and emissions levels with the U.S. fleet average by looking at labels on window stickers under a federal proposal made today.
The Obama administration is carrying out a 2007 law that requires labels to put new vehicles in fleetwide context for fuel economy, greenhouse gases and smog-forming pollutants.
The comparison must cover electric vehicles, plug-in hybrids and conventional gasoline and diesel vehicles.
