    What settings on the airconditioning/climate controls results in the best mileage. Yesterday, while in EV mode with 8+ miles remaining, I pushed the AC button. The EV miles remaining quickly dropped 7, 6, 5, 4 in less than a minute until I quickly saw what was happening and turned the AC off.

    Here in Arizona I have engaged AC while in EV mode. Typically I see a 10-12% drop in the EV range at that point. However I have a 3.1 mile commute and the last 2 trips with AC on at 72 degrees I used up 2.5 miles EV and drove 100% EV to work. :)

    Did you also have ECO mode engaged (OP)?

    You are just seeing the result of averaging.

    More useful is to know consumption rates.
    Moderate AC once the cabin is cooled off is about 500 - 1000 watts
    Moderate driving is about 7500 watts

    So expect AC to drop range 5 - 10%

    for best mpg's gas or electric, set fan to 'off', heat to 'low' if anything is on, it will cause more battery usage and/or gasoline.
