Tesla shares bumped up more than 1 percent in after-hours trading on Tuesday, after electric vehicle blog Electrek reported it obtained an email from Tesla CEO Elon Musk that says the company is halting production at its two main factories for several days to upgrade equipment and aims to produce 6,000 Model 3 cars per week by the end of June.
CNBC confirmed the email's authenticity.
The email, reportedly sent to all employees, sounded a strong call to action to get Tesla's auto production numbers up to expectations. It said that Tesla had built 2,250 cars last week — still short of Tesla's previously stated goal of 2,500 per week by the end of Q1. It also said that the improvements from the shutdown would set the company up to build 3,000 to 4,000 per week in May.
The company's factories will move to around-the-clock production, the email reportedly said.
Musk also had harsh words for the company's suppliers and contractors.
Moving forward, he wrote, suppliers must meet high standards for precision on parts or Tesla won't work with them.
