The design rate of the Model S/X production line is about 80 cars per shift. Since Tesla factory currently operate two shifts, the corresponding " as designed" rate would be 160 cars per day or 800 cars/week. During the Q2 ER the average gross margin guidance for Q4 was 25%. It is unlikely that this guidance can be achieved with two shift production output that is significantly lower that "as designed" output. Because of this I think that Q4 production will have to be higher then 600 cars/week if 25% gross profit guidance will be met.
Regarding the 570 cars/week production, I agree that this is an incredible achievement and should be celebrated, not mentioned as a disappointment in any way. I, however, think that the average weekly output is currently higher than that :smile:. Consider, for instance, what Elon mentioned in Germany, i.e. that current rate of cars produced for USA is about 400 per week. Based on interviews Elon did during the Geneva auto show, the European deliveries in 2013 were to be 5,000 to 7,000 cars. This corresponds to average European production output of 208 to 291 cars/week. The total would then have to be higher than 600 cars/week.
