Elon Musk says first Model 3 will exit the factory Friday

Tesla's affordable mid-size electric sedan, the Model 3, is ready for production, and the first car (Musk calls it SN1 which likely means serial number 1) will be completed on Friday. 

That's according to Elon Musk, who shared the news on Twitter, explaining the Model 3 passed "all regulatory requirements for production two weeks ahead of schedule." 

Musk also tweeted that he plans to throw a "handover party" for the first 30 Model 3s to be handed to customers on July 28. He says that production will grow "exponentially," meaning the company should be producing 100 cars in August, more than 1,500 in September, and 20,000 in December.  Read more...
