hose statements line up quite well with the Bloomberg Model 3 tracker, which has estimated a weekly production rate over 5,000 during most of August and is now forecasting that Tesla will nearly hit 6,000 in the coming week.
With those notes out of the way, I think we can safely estimate >20,000 Model 3s will produced in August, and possibly 22,000 or so. The 5th best selling car in the United States in July was the Nissan Sentra at 19,362 deliveries. If Tesla manages to deliver 20,000+ Model 3s, that will likely put it in the #5 spot. If the Nissan Sentra does end up a bit above the Model 3, Tesla’s premier mass-market car is almost certainly going to land in the #6 spot.
