There's an independent report out today on General Motor's much-vaunted Chevy Volt and it's rather enlightening. According to the Detroit News, Consumer Report's April annual vehicle survey issue isn't chorusing the Obama Administrations loud hosannas of the questionable car. Noting that the range in cold weather appears to be much less than claimed by GM, David Champion, the senior director of Consumer Reports auto testing center points out the consumer can get much better mileage from a Toyota Prius at about half the sticker price of a Chevy Volt.
