New Fuel Economy Labels Unveiled for New Cars

Until now, it's been difficult to compare the fuel economy of electric vehicles to those of conventional gas-powered vehicles.

The new stickers, required on all 2013 models, makes it easier for consumers to compare fuel savings at a glance, regardless of whether the car is gas, electric, or hybrid.

For instance, the labels show how much fuel or electricity would be required to drive 100 miles, and the time needed to charge a plug-in vehicle.
