I think the numbers in the spreadsheet for first half of 2018 is realistic at this point. I think it is hugely optimistic to assume a ramp to 10k/week by the end of 2018. Even Tesla has backpedaled from that projection. I don't honestly know what the projection is for the end of year production rate. Tesla at this point is not guiding for past Q2. I can only guess that it is somewhat above 5,000/week but below 10,000/week. My guess is that it will be closer to 5,000 than 10,000. If production at end of Q2 is 5,000/week, increasing to 6,300/week (my WAG) by end of year, that should allow for a ballpark number of approximately 200,000 Model 3 produced by the end of 2018. That seems like a pretty realistic number to expect at this point, but perhaps it is still optimistic.
