    Rated Miles. That's the EPA number or percentage on your instrument cluster or on the app. It's an estimate only.

    The outbound, uphill leg is the tricky one. How realistic is 349Wh/mi for you:
    • What is your current average?
    • What speed multiplier did you plug in and is that realistic for you?
    • Probably not an issue this time of year, but what temp did you plug in?
    The S90D has a rated range of 294, so it seems doable based on whatever scenario you plugged in.

    Range Mode will only add about a half a mile.

    Range mode will add more than a mile if you're driving conservatively. Don't be afraid to charge to 100% if you need the range (sometimes refered to as a range charge as a throwback to the roadster).

    EV trip planner takes elevation changes into account. So you need 197 rated miles. You should be able to make it just fine. Don't forget to allocate some energy for driving around your destination (if applicable) as well as loses while the car sits (turn on energy saving).

    Cool. Thanks. I made it to my destination only using 45% of my battery with the climb in elevation. Should be able to make it home just fine. Thanks for the input. Gave me the confidence to do it. Going the speed limit is the key.
    Any of you Arizonans, if it matters I made it from south Gilbert to Camp Lomia with 55% left.

    48? That's a lot of mileage. Or driving time.

    Did you really use 45% of your battery or was that the number presented to you on the dash when you arrived? Do you remember what % you started out at?

    I actually used 45% according to the dash (said 55% left), but when i left it was at 100%. I set it to trip 100% before i started my trip.

    Cool. Did you note what your average energy usage came up to be?
