The buffer has to be allowed to be used if it was used in the EPA test. And the way Tesla has been doing it on Model Y & 3 at least, the charging constant takes it into account (calculations using the charging constant (charging constant * rated miles @100%) to calculate lower limit on full battery capacity give a result that includes the buffer).and the unknown usage of the buffer,
But in any case, comprehensive data from a decent length charge giving: % added, miles added, and kWh added, should be good enough to get close. The answer will probably be ~103kWh though, haha.
As a reference point, the "old" 2021 Model S Performance 21" wheels was 103.5kWh, 117.6kWh to charge. 97MPGe (2021 MS Perf 21") vs. 101MPGe (Plaid) - that scalar (adjustment factor) is at work there I think - again, seems to buy a few %, in spite of any potential efficiency losses from 3 motors. (I assume that Model S didn't have the heat pump, right? I don't follow Model S, as I said...):
So I don't see any reason to believe at this point that there's a different pack in this vehicle; the approximate calculations align quite well. But we'll see. Need to just wait for all the numbers to come in.
