You aren't being true to your nom de plume. Do the math. 24 GWh/year is 6 GWh/quarter. A 60/30/10 mix of LR/MR/SR+ is ~72 kWh on average. 63k cars * 72 kWh = 4.5 GWh. Add 0.5 GWh for TE and it's clear cell supply isn't the issue.
Also compare this tweet to prior statements in the Q3 call last October:
JB Straubel
Sure. I can speak to that. This is JB. We have had a period, where the supply was fairly tight for Model 3, but it did not really constrain the Model 3 production in any significant way.
Elon Musk
Less than a week.
They made 53.3k LRs in Q3, or 4.2 GWh. Since then Panasonic added three lines:
JB Straubel
And we continue to bring online new production lines. So even just in the last several weeks, we've started up yet another cell production line with Panasonic and through the end of the year, there's another line coming on, and then one shortly after that. So there is a steady increase in the total supply.
They modified these new lines for higher output, 3 lines increased capacity 40%. This lines up with Musk's 24 GWh (vs. ~17 GWh sustained in Q3 from the 19-20 theoretical capacity Deepak quoted).
Managements spin numbers. Tesla is certainly no exception. The investor's job is to dig deeper.
You put too much faith into your model. We don’t know what happened. Could be that 24GWh/year was the rate at the end of Q1, not the start of Q1. As for rates for Q3 and Q4 we don’t know either, could be some leftover batteries from Q1Q2 and 2017Q3Q4 due to other bottle necks in production. Or something else. Or maybe you are correct. We don’t know...
