    It's my understanding that you can't "save" those green bars once you get home. They go away and when next you start your car, you have to gain them again. So #1 is outa luck.

    Remember....you cannot buy coffee....you can only rent it.

    You realize that Einstein worked on his Grand Unified Theory pretty much until he died without success. Just sayin. :p

    Yes, and there are plenty of people still a huntin' for that final theory. It runs along the line of thinking that the human predilection for breaking everything down to its lowest common denominator or finding ways to explain life in a thirty second commercial spot or a thirty minute sitcom, can somehow be fashioned in such a way to do the same to the laws of physics. I wager that the universe isn't going to accommodate that wish.

    Out of luck? Why? Where does it say anything about "saving" green bars?

    It just says that maximizing MPG-FE generally requires avoiding using the battery as much as possible. Don't charge it, don't discharge it, unless absolutely necessary.

    IOW, pulse (accelerate at a rate that neither charges the battery nor draws from it) and glide (coast with the ICE off, and no regen or power drawn from the battery)

    I believe I've read that this is how the best MPG-FE has been accomplished so far, and as a matter of physics it makes the most sense to me.

    (sorry, had to defend my "theory")

    The car will work hard to keep sixpence in its little box in the
    back. Anything extra you get to spend, but anything less and you
    have to pay it back.

    If you don't spend it immediately and try to stuff some extra into the box in the back, a fee is charged both for the deposit and the withdrawl.

    <div class='quotetop'>QUOTE(hobbit @ Aug 2 2007, 12:28 PM) [snapback]489369[/snapback]</div>
    Plus an additional fee.

    I've had green bars in the morning, left over from the previous day.

    It's not all that often that I have green bars when I pull in my driveway...
