Great info from Gali who has an valuable input on the smart guys around making P&L calculations for the future:
The production increase from 5k/w 3s to 10k/w is planned to have zero incremental labour costs (Minute 18)
The impact on margin will be therefore huge even if they manage to do the 100% increase with just 10% labor cost increase
I've said it before and I'll say it again: margins on Model 3 are going to be superb, even after SR/non-PUP enter the mix. The other thing to think about, beyond the above, is scrap/rework rates. If scrap/rework rates are currently high, as the shorts insist, think about what that does to the margins when they're not. On top of this we've had multiple analysts touring the Tesla factory back up the notion that Tesla can up production rates significantly just through incremental process optimization, and we just today got confirmation from an investor touring Giga that Tesla is well en route to achieving cell prices under $100/kWh by the end of this year.
