GM Announces That The Chevy Volt Will Have a 230 MPG Rating

DETROIT (CNNMoney.com) -- The Chevrolet Volt, GM's electric car that's expected to go on sale in late 2010, is projected to get an estimated 230 miles per gallon, the automaker announced Tuesday.

That exceptionally high government mileage rating could give the Volt a major boost. For the first time, car buyers will easily be able to compare electric cars with ordinary gas-powered cars.

"Having a car that gets triple-digit fuel economy can and will be a game changer for us," said GM CEO Fritz Henderson
