    It’s 0-100, EPA numbers are always 0-100. Real world range should always start with 80% of the EPA number to leave room at the top to protect the battery and at the bottom to give you some margin for getting to your destination. You should then derate that number for speed and temperature. They haven’t said if they will have a heat pump so I’d assume that they won’t which means that in winter the range will drop by as much as 40% if you have the heat on. Speed also matters, the range at 75 will be less than the EPA number, if you are on a back road on a perfect day you can beat the EPA number. For example yesterday I did a 100 mile round trip to Jaffery NH in my Model 3, I averaged 199Wh/mile, the EPA number for the 2019 AWD Model 3 is 234. The temperature was 75 so no effort was needed by the AC and I was entirely on back roads which meant that my speeds were between 30 and 45 MPH.
