All MY being delivered since early summer 2021 have 82KWh battery packs. Software hasn't fully enabled them all for range, just as spares.Based on battery day, I don’t think cars with 4680 cells in 2022 will have all the chemistry changes outlined, just form factor, tabbles connections, and maybe DBE. Also doesn’t mean they will have 400 mile range, they could just reduce the number of cells. I’m just waiting for the 82kWh cells like new M3.
MY v2.0 (with 4680) will likely have the same 82KWh rating, just fewer # of batteries.
400 mile range is not necessary since no competition is in sight and 4680 batteries are still precious.
There has never been any indication that Tesla is updating the MY suspension, but the rear megacast does have a recess, speculated as for an air tank.
