Tesla founder Elon Musk says his company will build an electric pickup truck, feeding interest among the entrepreneur's fans and sparking speculation about when it might be produced. Tesla is still working to get several vehicles to market, including its Roadster and Semi.

Musk made the remark on Twitter, responding to a request for a pickup truck by saying, "I promise that we will make a pickup truck right after Model Y."

The first-ever mass-market Tesla should roll out of the factory this week.

CEO Elon Musk tweeted late Sunday that the company's Model 3 car "passed all regulatory requirements for production two weeks ahead of schedule. Expecting to complete SN1 on Friday," using an abbreviation for serial number one.

Musk also tweeted that production would increase "exponentially," with 100 cars in August, more than 1,500 in September and 20,000 per month in December. Musk also announced a July 28 "handover party" for the first 30 buyers of the Model 3.
