    Actually, Model 3 has a 83.5 kWh battery pack.

    So took the car in yesterday... had a couple other minor issues in addition to this. They said they will test the battery.

    I have a model s75 in the meantime and so far it looks like the range is comparable to my 3....

    I would be interested to hear from the owners who own both cars and see what kind of range they get..

    ..notice I used the word « range »... not « kWh per mile » :)

    Just Put 80 miles on the S75 loaner...
    - Same consumption as last week with the 3 (I have the sport wheels)
    - range is very reliable (unlike on the 3)

    I suspect I will end up using less electricity overall. Anybody else noticing similar trends?

    For me the range on my Model 3 is much more consistent than my Model X. The MX seems to much more susceptible to winds and high speeds and varies wildly in those conditions. My Model 3 is pretty much spot on with the 290-310 range. I have 18" aero wheels with covers installed. The only condition that seems to lower my range more in the Model 3 than the Model X is cold weather.

    Probably nothing wrong with your specific car. I would simply calculate your real usage as ((277-118)*.240)/125 = 305Wh/mi. But without a logger, can't tell how much of that is vampire drain or preheat/precooling. But for reference, see the posts below:

    Enjoy.

    edit - also note that this could be part of occasional BMS re-estimation of SoC. Have to get enough data to rule that out. One drive is not a good enough sample size.

    Quick update here.. picked up my car yesterday.. they checked the battery and reported no issues.

    I did one small test a few minutes ago that is leading me to believe that vampire drain is not the only issue.

    Drove 3.7 miles at a 257 wh average. Range went down by 5 miles. How is that possible?

    I will posts longer tests.

    I don't think the range estimate is so accurate that you can expect perfect analysis of your range with such small distances. Let's say it displayed 200 miles range, but that actually meant some amount more than 199 and then you drove 3.7 miles and it rounded it down to195. That would show a 5 mile drop for 3.7 miles.

    Ranges are estimated, as battery SOC can not be measured exactly. It’s usually accurate to within a few miles of the actual rated range, but certainly not tenths of mikes.

    Are you talking about this

    If so he used kWh where he meant kWh and should have used kWh. If that confused you that is on you.

    That range penalty is completely normal for in-town short trips. My range hit is often 40% or worse for a week of in-town schlepping about. And that’s not in cold weather.

    Then I can get on the highway and from point to point, SC to SC with flat, non-windy conditions at reasonable speed, will get quite close to rated just like the virtual brochure sez.

    Can’t just read the Wh/mi numbers off the screen. Most people have no idea of their actual efficiency from charge to charge.

    Nope, was referring to this:
    "Our average consumption is around 267 kWh. So far so good. My understanding is the 310 range is based on 250 kWh."
