Musk’s earlier tweet that Tesla would make about 500,000 cars in 2019 was difficult to gauge -- given his proclivity for setting stretch goals -- and was greeted with some skepticism on the social media platform. The number he put in the posting late Tuesday was roughly in line with his previous comments, but that depends on which figure investors paid attention to when Tesla reported earnings Jan. 30.

In a letter to shareholders, Chief Executive Officer Musk and his chief financial officer forecast as many as 400,000 total vehicle deliveries this year. Within hours, the CEO told an analyst on Tesla’s earnings call to expect sales for just the Model 3 to reach as many as 500,000 units in 2019.
