Is hypermiling killing the battery?

    Are we certain that he claimed this for the 'v', not for the Liftback he was driving for a long time before that (and might still be driving)?

    Ah, another high mileage can only be achieved by being a road hazard myths. Sorry, hypermilers are usually the safest drivers on the road.

    I'm not even sure that we are arguing about Sagebrush. :) Who am I again? Either way, 70 is impressive in either vehicle. But exponentially more so in the V.

    Stop obsessing.
    It is just a CAR.
    It is intended to be driven like any other street car.

    The more conservative you are, the better your mileage will be.
    The more aggressive you are, the worse your mileage will be.
    NOTHING you can do to it within the scope of "normal" driving will "damage" it.

    If you don't enjoy playing all of the silly "games" to get a few extra miles per gallon, then don't listen to any of that chatter.

    I would probably not have 70 mpg tanks on Fuelly either, because the following would have to be true:
    1. My wife did not drive the car
    2. No highway driving
    I get the feeling that my earlier posts have been transfigured, as if I said that my Vagon's lifetime mpg is 70+ mpg. I wish! Read my posts; I said that economical driving habits combined with P&G can give 70+ mpg. The main limitation, at least for me, would be the weather. The P&G requirement means speeds below 45 mph, thus only city driving.

    If they don't get hit by road-ragers who are tailgating them.

    I don't disagree with you there, Im saying that if he is getting better than 70 on a V and without using EV only is a lie...

    I get my best mileage, by far on the highway using CC. If you drive like you have to to get 70 mpg (which I still think is an urban myth) in Atlanta, it would be a hazard to everyone else. The Highway Patrol would beat you up and leave you for dead, also. I know I would.

    I used to drive from Norcross to Canton every evening. My average would be 68mpgs for this trip. (stupid morning commute on a different route would kill my mileage) I cc'd in the slow lane at the speed limit.

    That is not an uncommon observation, but it usually means at least one if not both of:
    1. flat terrain
    2. Without cc you are an aggressive driver

    I go from Norcross back home to Lilburn and my Computer display at switch off hits the high 70's to low 80's consistently. On the way in its usually mid 50's (morning cold engine and slightly uphill from Lilburn). Still can't' get my actual above 55mpg on an average commute only tank. I'm beginning to think that instantaneous trip display is just to make me feel better.

    :)

    Try driving 3 - 4 mph slower. I'll guess you approach 60 mpg.

    adding onto the original question... while gliding a small amount of battery still gets consumed i.e. a/c, audio equipment and headlights usage.. i.e. after 2 cycles of gliding, one bar of battery gets dropped and consequently on 7-8 cycles of pulse and glide, battery gets to 3 bars and then i intentionally try not to p&g but to keep running ICE with very little pressure on the pedal to consume less gas.. and one the batter gets back to almost full state, i pulse and glide again .. the loop continues.. and i hope its not bad for the battery :S

    I wonder if the engineers had P&G in mind when designing the Prius or if it was simply designed to work in conjunction with the ICE. If it's the latter I would imagine more inconsistent cycling could be a detriment. I am going to change my position to "plausable" on this one.

    I drive mine like a regular car. My mpg is good enough in comparison to what I was commuting in that it simply does not matter.

    Cycling the ICE and the battery is the natural state of the Prius. P&G can be detrimental if the driver forces frequent deep battery drains.
    To be clear, P&G does NOT require or benefit from deep battery discharge, but the hypermiling driver may be tempted to drive that way for short term gain and satisfaction.
