no 4680 batteries will be
no 4680 batteries will be available soon. Only demonstrators, low rate production. Even if the publicly discussed engineering challenges were solved today, machinery and raw materials for production wouldn't be in place soon.
Any production from GigaTX will be using 2170 paks, maybe structural, maybe not.
I would guess a structural pak could be made using 2170 cells, but no one has mentioned testing of such (crash, NHTSA rating for the variances, etc).
