My whole point of responding to you was to was to point out that the range increase may not be attributed to the heat pump since the new Model S does not have one. I guess it's possible the new Model S could be getting a heat pump but wouldn't we hear about it already? The Model 3 heat pump rumors started up months ago.I mean that might be the case that they can get this increase without a heat pump - look at the various improvements made on the Long Range Plus. A lot of those seem like they could be transferred to Performance. But I don’t track it closely.
And how do we know the new Model S will not have a heat pump?
But I don’t want to dig into the details of what is going on with Performance Model S: Going back to the original message you responded to, I was commenting that it is very rare for the constants to change on Tesla vehicles (after they have shipped), even if the efficiency is increased. So for an existing vehicle, your rated range usually stays exactly the same, but your range increases. That is the typical scenario.
This standard approach by Tesla could of course change at any time. That’s why I was asking for more info from you. Specifically, it *sounded* like you were saying that 2020 vehicles were getting a 40-rated-mile range increase as displayed. Probably not what you were saying though. But this is just a simple case of a 2021 vehicle having a lot higher range, for various reasons, which is not unusual. And it will have a different constant, of course. 2020 vehicles will just keep their same old rated range. But their range may increase (depends).
Tesla's website already reflects the range increase for the Model S so whatever improvements they made is currently in production.
