Model X 2020 371m vs 2022 348m reduction??

[AustroTom]

Hello All,
Shopping for a Model X and came upon a weird discrepancy:

Why would Tesla offer a 371 mile range battery pack for 2020 models and reduce it back down to 348 for the 2022 models?
Aren't they using the same if not more advanced battery systems??
Any advise greatly apreciated.

Refresh dual motor X (2021 production and beyond) has a slightly lower overall capacity battery pack, and much larger rear motor than the outgoing Long Range Plus. It's more apples-to-apples to compare a Refresh Dual Motor to the outgoing Performance models, because their performance is similar from anything but a hard launch from a stop. If you compare them "apples to apples" on a performance basis, the new one is significantly more efficient, and of course, charges much faster than the older car. The charging is where the big improvements were - the new cars charge way, way faster, which is what actually matters for road tripping.
