While I understanding the concept of "230 mpg" is because you need to factor in the time the electric motor is running and not consuming any gas, but I just think it silly.

MPG of gas is unlimited when driving less than 40 miles.
However if you drive the car to get the total range on one tank on fuel, you might only get 50MPG.

Why can't the EPA come up with a better system.. since often you use the MPG to get the total range of the car. Average MPG x #of Gallon = Total Range.

With the volt.. the 230 MPG x 10 gallon gas tank = 2300 miles range on a tank of gas. Not.

Maybe I failed basic math.. but I thought the EPA can come up with a better system.
