How long does it take for the factory to make a model 3?

We took the tour on Friday and our guide said, "4-5 days" from start to finish for the car to move through the plant.
(I think he was referring to any Tesla, not just the Model 3)

 

Tesla produced roughly 79,900 model 3s in Q3 2019, so that's about 6146 cars a week, or 878 cars a day assuming they run the same shifts 7 days a week.

I'd expect that to be at least 5-10% higher for Q4 but we'll know that in a few days

 

Not sure if that math is correct because that’s assuming a dedicated facility that builds M3 nonstop. I assume they also allocate some times for Model S and Model X?

 

that should be correct / on the low side for model 3 in Q4.
I was told it is about 3 days from start to finish for a 3 now

 

The S&X are built on a separate line.
