2021 Model X, Monroney Sticker Range Increase

Ideas on why or how the MX Performance got a range bump of 36 miles to 341 miles? This is a larger increase than the LR+.
Million dollar question is whether they enable that on previously-sold X's, or only "2021 model year" ones ...
It'll play out similar to LR+ I am sure. Those that got the prerequisite hw changes will get update DU firmware and the new displayed range.
I suspect the new permanent motor might have to do with that. Really need to take a look at one of those cars to see what config changes are there.

@verygreen to me, that sounds like it should mostly just help out with city driving. So I'm guessing we shouldn't expect much improvement for interstate driving where we really want the extra range. Darn!
same as LR+. But then again it depends on how congested the interstate driving is too. I noticed that on congested roads when my average speed is lower due to all the slowing down because I cannot pass people the consumption is better. When it's 90mph no slowdowns - the consumption is much higher (almost on par with 2017 X100D).
So there is a new permanent magnet front motor for 2021 cars? Inventory 2020 MX Perfs are still showing old 305 range. Could be an oversight though.
the new PM motor was added some time ago in the list of ECUs, but I don't know where it gets installed. As such I cannot say this is it for sure, but seems feasible?

I don't think so, as you can see on the sticker the efficiency is the same (32 kWh per 100 miles). I think they increased usable capacity via voltage limits (higher max or lower min) or improved chemistry.
Well, once the update rolls out we'll see. But I doubt it's that. It's possible the sticker was not fully updated as a mistake for example or they improved charging efficiency (via the same process they are able to improve regen efficiency)
Typically when the pack capacity changes there's a much bigger change to the part number, not just a revision letter at the end.
Also I know somebody that has -H pack on the bench and it's still a 100kWh pack.
Now let’s just hope it will also apply to -G packs! @verygreen do you think this update could be for pack id93? (So both G and H packs)
Except to the extent it reduces weight if pack capacity is not increased.
They say that, but it's becoming more the trend of batched updates. It's extremely difficult for an automaker to manage their supply chain, engineering designs, and spare parts inventory if there's too many changes per week. I think it was more normal early on, because Tesla had no choice but to fix flaws they discovered as quickly as possible.
We will still see more weekly innovation at Tesla than other automakers, but primarily related to software. I think the hardware aspect is updated less frequently because of all the issues it creates. Let's not forget Tesla had been working on the Model 3 (per a video interview with Elon) as early as their IPO in 2010. These new creations and their updates are probably more involved than we'd like to admit with Tesla, but some of them may be here already and here to stay. I think it's okay, because I'd rather get fast repairs due to easier sourcing of spare parts, more consistent build quality, etc.
I don't think they have the same number of minor issues as they used to and so they don't need to do such frequent hardware changes.

Yep, 40.4.5 does the trick. I just installed it and my car is charged to 83% / 309 miles. Extrapolating gives 372. Yahoo! Even if it is smoke and mirrors, I'm happy. Release notes below:

Awesome! It looks like capacity did indeed increase!
“Your car will now display a slightly higher range to more accurately reflect the capacity of the battery”
Sweet - congrats! Now let's see if my antique June 2020 "G" pack will do the same ...

My X is at service, I did the update remotely. I am in % mode so I had to use TeslaFi to see range remotely. Extrapolating I get 370 miles at 100%. SOC didn’t change, 77% before and after update. Maybe they opened up some from the bottom, or just a multiplier change.assuming it was 83% before update - the capacity did not really change
