That’s a bit of a painful read. The 4680 will increase the range and reduce the cost. Last number I had was 13% increase in range.
It can still be that the software is being conservative on the current 4680 MY battery capacity and they will offer a slow reveal of it's full capabilities after tuning cooling/charging of them in the field, they don't want to queer the existing cars market&residuals too.
they have been cagey on the new cells capacity and weight - catl had some comment that their version has some 14% more energy in the form factor too,
maybe the tesla employee owners are sworn in the short term not to resell for a competitor tear-down too
