Unfortunately most of the benefits of structural battery packs haven't materialized yet based on the stats Tesla submitted to the EPA. The Austin Model Y is 25 lbs lighter but has 14kWh less capacity and 51 fewer miles of range. Part of this is probably the battery chemistry being used in the current 4680 cells and as the chemistry improves they may catch back up in range to the non-structural 2170 packs but they have a really really long way to go before they get to the range increase and weight decrease they promised at battery day. That or some aspect of the EPA numbers are massively wrong but I feel like we would have heard from Elon about that by now.
