I would like to know more about what occurs with the drivetrain as I drive down a 2,450 foot mountain as I do several times a week.
Ok, as I begin desending, I shift into B. This of course helps the car slow down and I don't need to use the brakes as much. Then, as I get to about 2,000 feet down the battery becomes fully charged as shown on the Energy display, and at that point I must shift back to D to prevent what sounds like an overreving situation. This, despite the Energy display showing that the ICE is not running.
My questions related to this:
What is the sound I hear as I decend the mountain in B even before it begins its fully charged battery louder and higher "overrev" and even afterwards in D, though quieter? The transmission?
If its the ICE, why would the Consumption display show that I'm getting at least 99.9 MPG and the Energy display show that the ICE is not running all the way down? Wouldn't a reving engine cut down on MPG? Related to this, I've lost a pip during this descent--another curiousity.
