New York Times : The US Environmental Protection Agency is struggling with how to rate the fuel economy of the Chevy Volt, Nissan Leaf, and other electric cars. As Nick Bunkley and Bill Vlasic of the New York Times report, the tricky question is more than academic. By law, new cars for sale in dealerships must have their miles-per-gallon ratings displayed on their windows. The Chevy Volt does at least have a gasoline-powered motor that switches on when the battery is low. The Nissan Leaf, however, is wholly electric.
