Does Max Range make (enough of) a difference?

    I don't have good, like-for-like, data, but the data that I do have looks like Max Range makes no, or so little, difference as to not be worth it. Plus I definitely have a high-pitched wine on max Range - not something I notice when i engage it, but a couple of hours later when I turn it off my ears definitely notice - I would liken it to them saying "thank you"!

    Trouble is, for me, that when I drive on max Range I put TACC on 73 MPH, whereas when I'm not on Max Range I set TACC to 80 ... hence data not comparable. I guess I need to do a decent length highway run at 73 MPH with Max Range off :)

    Is there any data / opinions on whether its worth bothering about?

    In my experience, range mode makes little or no difference. There have been times where I would swear it actually increases power consumption. I stopped using it.

    That's exactly why I am using it :)

    It definitely makes a difference for the D models. Torque sleep is not enabled unless you have the range mode on. The whine that you hear is the increased use of the front motor.

    Thanks. I'll do the 73 MPH TACC test next time I have a decent distance run to make ... and maybe also an 80 MPH MaxRange run too.

    I am guessing that there must be an ideal speed that suits front-motor torque sleep? Perhaps 73 MPH is a lousy speed choice in order to get the greatest saving?
