The announcement came, unsurprisingly, in the form of a tweet, and said production ramp-up for Model 3 would need to hit 5,000 cars per week before additional complexity could be added. Considering the trouble Tesla has had in meeting even 2,500 cars per week, this announcement comes off as a case of the cart going directly before the horse.

Add in all of Tesla's financial instability of late, much of which is a direct result of failing to meet Model 3 production goals, and the idea of a dual-motor Model 3 seems even more unlikely. That said, the news came from a guy who launched his own car into space, so who knows.
