Tesla did not immediately return a request for comments about the launch.
The all-electric Model 3 is the linchpin of Tesla’s expansion plans, which include adding new passenger and commercial vehicles to the company’s lineup, selling a solar roof, and the ability to produce cars at an annual rate of 500,000 by the end of next year.
Earlier this month, Musk tweeted photos showing the very first Model 3, a black model that will belong to him. Tesla board member Ira Ehrenpreis was first in line to receive a Model 3, but passed the rights to Musk as a birthday present.
Musk has said Tesla expects to produce about 100 Model 3 cars in August, ramping up to 1,500 in September and possibly 20,000 a month by December. The car is expected to cost about $35,000, roughly half the price of an entry-level Model S, Tesla’s luxury all-electric sedan.
