Martin Viecha -- Senior Director, Investor Relations Okay. The second question, we've already answered regarding Model Y delivery. So we'll jump to the third question from Craig. News reports suggest that Gigafactory may already be producing Model 3s for Chinese market. Could you please update us on the production expectations for Giga 3? And confirm purpose of the second building now being built. Is that for battery production as suggested by some press outlets?
Elon R. Musk -- Founder, Chief Executive Officer & Director Yeah, we're in trial production of Model 3, basically sending cars through the system, and we're ramping rapidly. We're expecting to hit volume production in a few months essentially. The second building is indeed for battery and module production. And there's probably -- there's obviously a bunch more construction beyond what is already there because obviously we need to build out more facilities for Model Y production at Shanghai as well.
