That's actually a bit complicated, because the EPA doesn't really have a category for the Volt, and they don't think their test is fair, in that the fuel economy is very high. During the test, the Volt will complete 85% of the EPA test without ever using the gasoline generator. So in the test they end up getting a fuel economy of over 100 mpg. The EPA thought this unfair, and made a new test for the Volt, so that it would have to complete the test with it's batteries nearly fully charged, which is ludicrous. I mean how many people fill their gas tank every single time they drive?
I'm on 1/4 of a tank right now in my car...
So, the gasoline generator will get close to 50 mpg, but it's not used until the battery charge drops down below 25% or something like that. When you add it all up, you get close to 85 miles worth of pavement for one gallon of gasoline, assuming that you started your trip on a full charge, and your driving habits are close to that which Chevy used to test the vehicle.
Of course that goes the same for other vehicles too. My Echo doesn't get quite the same fuel economy as the sticker says, but that's because I have a heavy foot![]()
If you continue to have a "heavy foot", gas mileage could be the least of your expenses and if it continues long you'll probably be trading in your Volt for a good pair of walking shoes.......:lol::lol::lol::lol:
