Tesla appears to be closing in on its goal of producing 5,000 units of Model 3 cars per week. The Silicon Valley superhero team just unveiled a third production line, apparently assembled in a mere three weeks in a lightweight aluminum structure next to the Fremont factory. [Editor’s note: The  structure has been widely described as a “tent,” or “temporary,” but as a couple of readers have pointed out, there are examples of such structures that have been in service for many years.]

“Amazing work by Tesla team,” tweeted Elon Musk. “Built entire new general assembly line in 3 weeks w minimal resources.” He included a shot of the first Model 3 dual-motor performance model coming off the line.

Last week, Musk congratulated Tesla employees in an email, but said “radical improvements” were still needed to reach the company’s production goals. “All parts of the Model 3 production system are now above 500 [units per day] and some are almost at 700 cars already,” said Musk (via CNBC).

Wall Street loves the latest production news – Tesla’s stock continued its steady climb, utterly ignoring a sensational video of a Model S fire that appeared over the weekend. (History repeats itself department: TSLA soared in 2012 as the market realized that Model S would soon be in production, and again in 2017 as it became apparent that Tesla would launch Model 3 more or less on time.)

The Tesla-hatin’ trolls went into overdrive, tweeting that the new assembly line was “a fake mock-up,” and that Musk’s snapshot was “Photoshopped.” Equating the trolls with the poor, long-suffering short sellers, Electrek’s Fred Lambert asked Musk to elaborate. However, all the Iron Man had to say was: “They have about three weeks before their short position explodes.”
