CJ, > And the more efficiently you can recover it, the less gasoline gets burned. The key here is that all of the energy essentially comes from gas. How much of it actually gets translated into mileage is the question that MPG is supposed to answer. GM is going out there and claiming "230 MPG" for the Volt. But not all of the energy comes from gas. In fact, in order to achieve "230 MPG," most of the energy has to come from a wall socket. > This looking for what you perceive as "gotchas" to the point that you totally distort other people's arguments is a peculiar affliction that you have caught from i-node. If you're going to accuse me of "partisanship," don't complain when the level of discourse drops to that of a flame war. > Plugged in or not, the Volt is going to be a lot more efficient than a regular hybrid. That really depends on how much energy current hybrids waste because of limited battery capacity. AFAIK, most hybrids simply shut off the engine when the battery is fully charged up, at least in city traffic. (Highway doesn't matter, since the gas engine is doing all the work anyway, and that's when the gas engine is most efficient.) The big difference in the Volt is that the battery capacity is much larger. Hence you can plug it into a wall socket overnight and get 40 miles out of one full charge before the gas engine needs to be used. I would like to know just how much MPG the Volt can achieve without relying on the wall socket. I bet it's not much more than current hybrids. Tenchusatsu
