@conv90, replying in this thread to your other inquiry; not sure whether you got the summary answer for yourself here, but currently, the battery with ~80.7kWh (say range of 80.6-80.8kWh roughly) shows 499-500km for 2021 Model 3 Performance, as several have commented above. If you look carefully through the many pages of this thread, you'll see some exact calculations but this is close enough. I'd focus on the kWh capacity, not the rated km number, as described in this thread.
In the US,
eventually this will show 315 miles (507km), this would not be an increase in range though (500km and 507km would be anticipated to be equal energies). My suspicion is they haven't updated the software to reflect the EPA rating of 315 miles (with associated constant change) because they're anticipating redoing the test (since the AC charging data and thus the MPGe for the 2021 Model 3 Performance appear to have had a major problem in the first EPA test - though the range I expect to be correct; the test issue only affects the AC number, MPGe - that being said, when they rerun the test they may get a better range if there have been any further software optimizations since the first test in latter half of 2020). It's also possible they'll unlock some additional Performance battery capacity too, though that's a lot less clear to me (getting cell voltage data from Performance owners at 100% and 0% via SMT can be difficult, though it may have been posted here - any ~1kWh capacity lock, if it is possible, could come from the top or the bottom of the pack). I only
speculate this may be the case since no one seems to have hit the 82.1kWh "Full Pack When New" value for the Nominal Full Pack value.
To be clear, this is a lot of speculation. What we do know for sure is that the EPA MPGe numbers are wrong for the 2021 Performance Model 3, and that Nominal Full Pack does not match Full Pack When New (which is somewhat atypical for new cars). I'm not aware of reports that latest software updates have resulted in 2021 Performance in the US showing 315 rated miles (if anyone can report that of course chime in). But I think we're still waiting.
