After the scheduled shutdown in April, the Tesla Model 3 production line is reportedly closing in on 4,000 vehicles per week.

The figures were first reported by Tesla Motors Club member bkmxp100d, a Tesla owner who stated that they were informed of the numbers by a friend working at the Fremont factory. The production shutdown last month reportedly had a positive effect on the pace of the Model 3 line, allowing the electric car maker to manufacture 4,290 Model 3 in 7 days, with a peak of 638 vehicles in 24 hours. The next scheduled shutdown for the Model 3 line is reportedly scheduled for the May 26-May 27 weekend as well.

While the numbers provided by the Tesla enthusiast appear to be optimistic speculations, the ramp to 4,000 Model 3 per week is roughly in line with the estimates of Bloomberg‘s online tracker. Currently, the tracker shows that Tesla is pacing towards a rate of 4,000 vehicles per week. Other members of the forum community also stated that their own sources from Tesla are reporting Model 3 production figures hovering slightly below or just above the ~4,000/week range. VIN registrations from last week were encouraging as well, with Tesla filing more than 8,000 VINs in a single week.

During the first-quarter earnings call, Elon Musk mentioned that what he is “most excited about” was the rapid increase in the production output of the Model 3 line. Musk even noted that the Model 3’s peak hours already correspond to 5,000 vehicles per week.

“The thing I’m most excited about is the rapid increase in output. We got just in the last 24 hours at the Gigafactory managed to achieve a sustained rate of over 3,000 packs per day – sorry, per week, and actually reached a peak hour with extrapolated outward would be a rate of about 5,000 cars per week.”

“We also saw enormous improvement in zone four of module production. This, I should point out, is a fully automated zone, and we’re able to also achieve sustained rates of 3,000 vehicles a week. So, we’re actually slightly ahead in factory module and pack production than expected. And with some work at the Fremont vehicle plant, primarily in the general assembly area, I’m confident we will very soon exceed the 3,000 mark in Fremont.”

Responding to an article published by Ars Technica about how the company’s issues with its machinery were reflective of GM’s struggles back in the 1980s, Musk recently tweeted that the company is currently working on the Model 3 line’s “worst production choke points.” Musk also noted that a “Hackathon” — a fast-paced programming session that sometimes lasts for days — is currently ongoing, in order to address bottlenecks in the Model 3 line.

Fair criticism, but we’re fixing it fast. Hackathon going on right now to fix 2 worst robot production chokepoints. Looks promising. — Elon Musk (@elonmusk) May 14, 2018

Since the first-quarter earnings call, Elon Musk has doubled down on his rhetoric about the Model 3’s production numbers and Tesla’s profitability by the third or fourth quarter of 2018. Just a couple of days after the earnings call, Musk stated that the “short burn of the century” is about to come.

“Oh and uh short burn of the century coming soon. Flamethrowers should arrive just in time. It will be next level. These are really big numbers,” Musk tweeted.

Musk also took the battle to the company’s short-sellers, buying 27,097 Telsa shares, which correspond to an investment of nearly $10 million in TSLA.
