    Now that the weather in New England is finally starting to warm up, I wanted to revisit my efficiency numbers I'm getting on my ~80mi commute. These are car readings, so they do not take into account charging losses.

    Morning commute clocked in at 168Wh/mi. Ambient temperature was 50F. Used heated seats but not HVAC heat. This route has a slight net loss in elevation.

    And here is the overall consumption for the round trip: 184kW/mi. Ambient temperature was 70F. HVAC fan was running but no A/C use. The return trip has a slight net gain in elevation.

    Most of this drive is on the interstate with moderate traffic and EAP engaged.

    Overall, I'm very happy with these results. Using 14kWh for a ~80mi commute is really awesome. It's around 5.5 miles per kWh. My rated range dropped 64 miles for this drive.

    What are other people seeing? Is this consistent with your commutes?

    Can you change it to show miles per KW?

    just do 1000/[the Wh/mi number]

    I could avoid saying "I told you so" but that would be modest.

    Nice results !

    By the way, the average was 177 Wh/mle, or 5.63 miles per kWh

    wow.. with that efficiency you are looking at 5.5 * 72kWh (usable) = 396 miles !!!

    What are you, Tesla ? Stop short changing the man.

    78/0.177 = 440 miles

    No, sorry now seeing that including the morning number is just confusing. the 184Wh/mi number is the round trip (average).

    I saw 188wh per mile today. I love the efficiency of this car. Heck, with ac blasting I still see son 205wh per mile.

    Sometimes the efficiency numbers are unrealistically so good, I get the feeling that it is rigged. Honestly. I was looking to see where the loophole is..

    r/t corrected to 184 Wh/mile so
    184 Wh/mile divided into 78 kWh usable capacity

    78/0.184 = 424 miles

    Looks like on your first leg you were averaging about 20mph, that will definitely help efficiency, as you are right at “max range” speed!

    The average speed is a bit misleading here. This is one of those commutes where you have 5 miles left, but it takes 49 minutes to travel those last 5 miles. Which means the first part of the morning commute was actually pretty decent (fast speeds).

    Well i drove to work this morning without the HVAC and no seat heaters.Mostly level road North of Boston. Air temp 55 deg. My commute is 13 miles mostly stop and go traffic with a few miles at 50 mph. I saw a big increase in my efficiency. I averaged 162 Wh/mile. So for me shutting off the HVAC is a big savings.

    I’m nowhere near this... 33 miles at 288 wh/mi (traveling at 75mph). I suspect my higher speeds (above 60mph) is the biggest culprit.
