[ad#post_ad-1]The original Chevy Volt concept car was described as having twin 6 gallon gas tanks, 50 MPG in charge sustaining mode, and thus 600 miles of gasoline range.
With production, these parameters were changed.
GM has not announced the production Volt’s miles per gallon in charge sustaining mode, though the evidence suggests it will be somewhere between 30 and 50 MPG.
“That’s interesting speculation on their part,” said Volt chief engineer Andrew Farah. ” But I haven’t told anybody who’s asked how big it is.”
“We’re not releasing the size of the tank yet,” he added.
Previously, then Volt executive Frank Weber told GM-Volt.com that the tank would be between 6 and 10 gallons, and Farah confirms at least that it is less than 10 gallons.
But why is GM being so vague about this figure?
“The reason we’re not (announcing it yet) is we want to make sure we get over 300 miles of fuel range,” says Farah. “We’re going to tweak it as such and I’ve got plenty of time to do that.”
Thus it seems GM is aiming for 300 miles of gasoline range, and therefore average real world charge sustaining miles per gallon will be the principle determinant of how many gallons is needed to reach that goal.

How big is it? You decide.
