my wife Me was built in Jun 2019.....have only seen 309 at 100% and 305....90% shows 275-279.......was always 279 until 2019.40x

Anyone LR AWDs Showing 322 Miles Fully Charged?

It should have been part of the paper work that comes with the new car. Maybe they don't supply that anymore. It lists all the features, etc., including fuel economy.
80% at 254 would be 317.5 miles, which is within 1.5% of 322 miles. Normally, it should extrapolate reasonably well at 80% charge.
And the number has nothing to do with driving efficiency.

Yep, 315-320 miles or so. This is the first report I've heard from an AWD which actually has more than the 310 rated miles displayed, which is confusing to me. I would have thought there would have been more reports in this thread (entirely possible I missed them).
In any case, from my reading of the EPA submissions, it looks like Tesla might be removing the "hidden" initial loss of capacity in 2020. Not sure how things will settle out in the end, though. But given that the 2020 AWD test article started with 79.8kWh of capacity, it seems like a lot of vehicles would fall short of that 322 mile range, quite rapidly, if they are revealing the loss of capacity right away. The Performance 18" is a different matter since it has better underlying efficiency and is less likely to disappoint...even though it too had a very large battery capacity, it was also voluntarily reduced...that being said, it will still immediately show loss of capacity assuming this is the way it is working now. It's very confusing, though! Immediate capacity loss does seem to be what is being reported by Performance owners, though. I haven't seen many reports of 299/304/322...
It's possible the 19" and 20" Performance will hold their max a little longer in some cases since those numbers seemed to be based off a 78.5kWh test article. I guess those numbers may still be capped and the first kWh of loss or so may be hidden if you happen to be lucky enough to start with a battery with 79.5kWh of capacity. Very confusing, as I said...
Here's a summary of EPA data for 2020 .

My 2018 Dual Motor showed 320 briefly on the app today after a deep charge/discharge, then showed 305 minutes later, then 312, so it's all over the place, 10k miles

That's probably just a rounding error, which is bigger the lower the SOC.

Yes as Ken says, it is rounding error.
As I have said before - these projections in the app are only loosely related to your full capacity - you will see them change dramatically (from minute to minute) especially at a low stage of charge. For example, here you might have had 44.8 (the API knows the decimal on the miles I think) miles at 14% SoC (API does not have access to decimal on SoC). That extrapolates to 320 miles. But you were more likely at 44.8 miles at 14.49% (309 miles). Charge just a little longer, get to 45 miles at 14.6%, that is 308 miles. But it will display as 45 miles at 15%, which extrapolates to 300 miles - and will display as so in the app.
So you have possible error at 15% SoC of +/- 10 miles or so. When you are at 90% the error is about 6 times smaller, so +/-1.5 miles or so (small enough to not matter).
Just as @AlanSubie4Life notes. Today, I was driving and I have Stats open and I can see as I drive the estimated Rated Range varies from 313 to 307 miles. As the miles pass by, the rated range slowly drops from 313 to 307, and then the SOC changes from 59% to 58%, and boom, the rated range pops back up to 313 miles. It's just rounding.
Me too: 80% goes to 249. I hope that number goes up come springtime...
It says 249, but I get about 50%... i.e. if I drive 10 miles, about 20miles come off the displayed range.

This is what happens when you get 460-470Wh/mi. Turn off the heat and you’ll be fine, albeit a bit cold in Upstate NY.

Thanks for that update...not surprised. Can you update us with what the projected full range is when you are at closer to 80-90% SoC? This projected number is more accurate the higher the SoC. We are expecting 322 here...and it is possible given you currently see 319 with a large rounding error (+/-5 miles or so).
Can you also take a single picture of the Energy Consumption screen showing:
1) Rated miles/km remaining (number next to battery symbol)
2) Recent efficiency
3) Projected range
All numbers need to have three digits for accuracy...
Thanks...

so in a Tesla, "Many are cold, but few are frozen..." ...apologies to Matthew...

Unfortunately you did not capture the rated miles, but I will assume ~70% SoC, or 226 rated miles (we know it ends in 6 and I know roughly what the answer should be...):
So, assuming that is correct, it does look like the 2020 Performance 18" constant has been lowered, exactly as expected.
Previously we were seeing a 247Wh/rmi constant with 314 rated miles at a full charge. (247Wh/rmi*314rmi = 77.55kWh)
Now they have adjusted to:
366Wh/mi*149mi/226 rated miles = 241Wh/rmi
So, 322rmi*241Wh/rmi = 77.6kWh (about the same quantity).
So all is well. Assuming I'm right about that 226 rated miles!
This is basically exactly what I would have expected from this vehicle based on the EPA results.
I expect the constant for the Performance Stealth 19" to be: 255Wh/rmi
And the constant for the Performance 20" to be: 260Wh/rmi
(This can easily be determined by changing your wheel configuration and recapturing this picture, capturing all three numbers.)

yeah this doesnt mean much until you charge to 90% or full. mine has shown 402km before (sr+) and then charged up it goes back down to 396km.

Definitely true - in fact, his range is probably closer to 322. It's rounding error causing the difference when he's at 60% SoC, where the error is +/-5 rated miles. But the charging constant change demonstrated above makes it fairly unambiguous - 2020 Performance vehicles before were showing 77.6kWh available so assuming he's still above that value it would make sense that 322 rated miles would be his maximum given the new constant.

Great post, thanks, yes you are correct, it was set to 70% so rated miles were at 226

It'll be interesting to see a similar screen capture from a 2020 LR AWD. Up until now they have not shown any increase in range, but I heard people reporting that in another thread. I'd expect a similar (identical) constant for the AWD, even though according to the EPA test, it is not as efficient as the Performance. (It should be a little easier to get the rated mileage in a Performance than an AWD.)
