I live on the west coast so will likely get a Model Y from Fremont. I hear that Austin will start producing MYs with the 4680 structural battery pack in early 2022. Are the same changes being planned for Fremont, and when will Fremont also start producing MYs with the 4680 battery pack?
The original plan seems to have been for Austin to begin solely with 4680 / structural packs (which also enable both F+R megacasts and save 440lbs of weight).
Fremont would follow. Both factories would build the same vehicles until Austin fully ramped up, then Austin would be primary location for MY.
4680 is delayed, so plans have adapted.
There are massive stacks of front megacasts outdoors on the Fremont lot. Clearly seen on Fremont Flyover drone videos.
That's a clear indicator that 4680 / structural packs will be used there, soon as possible.
There's a backup plan for use of 2170 battery packs with the F+R megacasts, saving 200lbs weight, and that might happen but Tesla seems to be waiting for 4680.
So maybe 4680 is close enough for Tesla to wait it out.
At the 3rd Qtr Earnings call, VP Engr said they plan to trickle out some chassis in early Q1 22 but ramp up won't be until later.
ONLY TESLA KNOWS what is going to happen, and when. All else is speculative. The internet blogs are nothing better than speculation.
This posting is opinion. YMMV
