Not long ago, General Motors said that the Environmental Protection Agency (EPA) would give its new Chevrolet Volt a fuel economy rating of 230 miles per gallon. Nissan then countered, claiming that its Leaf EV would get a rating of 367 mpg. That touched off a controversy that continues today.As a result, the EPA will be changing the way it determines fuel economy of electric vehicles.
A government agency known as the National Renewable Energy Laboratory said that the new rating system will provide two pieces of data — or numbers. Dror Ben-David, CEO of ETV Motors, maker of self-charging hybrid-electric propulsion systems, called for a rating system that includes three numbers — one to show how far a car can go on a single charge; one to show how energy intensive the battery is; and one showing how much gasoline the car consumers to drive the generator or wheels when the battery runs out.
So far, no one knows for sure what EPA’s two number system will be.

thesavagepony: won’t make sense with the chevy since its recharged with the gas engine once the battery’s sufficiently drained.
This is ridiculous….personally the main number should be how long it can go in a single charge. I think that will be best to sell electric cars. If you think about it, you can set that as the minimum bar for electric cars….at least people know that they will go that far without a problem. Then again this is just my opinion.
