Here is my estimate for 2019Q4 Model 3 Production: 988/day (86,944 tot. for Q4)
This is a purely naive statistical estimate based on an ordinary-least-squares fit of production data to a linear model for the 3 preceding quarters in 2019.
Notice the insane R^2 (R-squared) value of 0.9999996
Curves don't fit any tighter.
To me, these are the kind of numbers you get from production planning done months (or years) in advance, with a complicated and lengthy supply chain that reacts slowly, as you would expect for any large auto manufacturer.
I think these numbers are planned way in advance, and all the drama and intrigue is partly Kabuki theatre on the part of Wall St. analysts, and partly Tesla not wanting to reveal their hand too soon. Well howdy...
Per the table above, this model predicts 302,287 Model 3s produced in 2019. Adding in the YTD Model S/X production of 44,985 then that leaves just 12,718 Model S/X production required for Tesla to produce 360K total vehicles at Fremont in 2019. Easy-peasy.
A more reasonable estimate is that Tesla can at least maintain the Q3 Model S/X production rate, which then puts Fremont at 363,600 total vehicles produced in 2019.
Remember, GF3 production is a bonus. I've seen 2019 estimates here as low as 3K units by year end, and some at 5 or 10K. Let's be clear though: any number in those ranges puts Tesla total production for 2019 between 366K and 374K.
More projections for the GF3 + Model Y 2020 rampup to follow (maybe next week).
Cheers!
