Tesla appears to be closing in on its goal of producing 5,000 units of Model 3 cars per week. Elon Musk has just tweeted a photo showing a third production line which was apparently assembled in just three weeks.

Although it does appear to look like just a big temporary structure built at their Fremont factory the news has been very well received with Teslas shares increasing in value. The photo also shows the first Model 3 dual motor performance coming off the line.

“Amazing work by Tesla team,” tweeted Elon Musk. “Built entire new general assembly line in 3 weeks w minimal resources.”

Musk has also gone on record in an email to staff saying “All parts of the Model 3 production system are now above 500 [units per day] and some are almost at 700 cars already.”
