Right now I hear a lot of predictions and calculations that Q4 will only be slightly above Q3. That may be too conservative
In
my comment on Oct 20, 2018 I estimated 2018Q4 Model 3 production at 74,000.
Since then, we've received 2 important pieces of new information:
- Elon stated the goal of producing 1,000 Model 3s per day by Nov 28
- DISQUS commenter 'carsonight' tells us GF1/Panasonic now has 13 bty cell lines: 10 x 300K/day + 3 x 400K/day
Let's see how acheivable that rate is. To convert GF1 cell output into Model 3 production, lets make the following assumptions:
- 4.2M cells/day max. output from 13 GF1/Panasonic bty cell lines
- 50/50 allocation of bty cells to Model 3 LR vs MR (my WAG*)
- 4416 cells in each LR (known from 3rd party teardowns)
- 3648 cells in each MR (est'd 38 parallel groups of 96s strings)
That bty cell production rate supports max. 1,050 Model 3s per day:
- 2.1M cells/day / 4416 cells/LR = 475 LRs / day
- 2.1M cells/day / 3648 cells/MR = 575 MRs / day
So we can see that GF1 is producing enough bty cells right now to support Elon's goal of 1,000 Model 3s produced per day during Dec 2018.
Note: 'carsonight' has recently commented that 2 bty lines at GF1 have been reallocated to Tesla Energy (T.E.) use. As shown by the Model 3 cell requirements above, I don't think there's enough production yet to allow a switch-over to T.E. production.
However, it's possible that Panasonic will upgrade the 10 original lines to 400K cells/day output (JB mentioned this during the 2018Q3 Earnings Call). If that has occured already, then target Model 3 production could be supported with 11 lines, and 2 could be reallocated to T.E.
Finally, here's my updated estimate for 2018Q4 Model 3 production:
Oct: 12,200** + (685/day * 14 days) +
Nov: 860/day * 26 days +
Dec: 1000/day * 26 days =
21,800 + 22,200 + 26,000 =
70,000 Model 3 in 2018Q4
That's consists of 41K LRs (AWD+M3P) and 29K MR (L3MURs). We'll know in a less than a month. Exciting times!
CH3ERS!
P.S. WAG* = Wild Ass Guess
