The $41K car that gets 27.3 mpg - The Truth about Cars has an interesting report about how General Motors refuses to give a mileage estimate for the Chevy Volt when it's running in gas-mode (i.e. CSM or "charge sustaining mode.") GM is waiting for some new-fangled EPA method to determine mileage, even though they can certainly make their own test and report that on the sticker. Plus, you have to wonder - given the federal government's large stake in GM - whether the EPA would be inclined to "help" with the Chevy Volt's mileage estimate to a higher number than the one found by an astute TTAC reader.
