    I notice when I lift of the gas to glide, the car slow down quite a bit as the regenerative charging is on. Putting on neutral "free" the car to glide better, but its really is to much trouble to do it all the time.

    For a proper glide you feather the gas to a neutral position: no thrust and no regeneration.

    You could make the drive more entertaining, if you have satellite radio, by switching between NPR and Fox News, all while trying to keep your foot steady at 48 MPH. This would ensure that your experiment includes more balanced testing conditions.

    I find it works better it lift my foot completely, then put it back just enough to start gliding.

    This is often required to get GPH to drop down to .02 or thereabouts. Lifting off only slightly then reapplying pressure tends to allow GPH to only drop into the low .20s or so. I've been watching this on the SG2 lately. It is causing me to change my gliding habits.

    This works by encouraging the ICE to stop.

    You are correct, I have always just done it by feel, you can feel when it releases and starts to glide. Thanks for reminding me!
     
  10. I did it for years with my 05, and all my other cars, never had a transmission problem.

    The question is what happens above 42 mph, where if you were gliding, the engine would spin up to keep the MG2 from over revving. If it doesn't do so in Neutral, it would seem that that might be an issue. Toyota goes to a lot of trouble to ensure that the motors never get over revved, so I have to think they do something in this instance.
