Elon Musk on missing Model 3 production deadlines: 'I've never made a mass-produced car. How am I supposed to know with precision when it’s going to get done?' (TSLA)

Tesla missing its deadlines for Model 3 production targets was not done on purpose, rather it was done out of stupidity, CEO Elon Musk said during an interview with '60 Minutes' on Sunday.

"Well, I mean, punctuality is not my strong suit.... Why would people think that if I've been late on all the other models that I'd suddenly be on time with this one," Musk said.

When it was pointed out to him that his critics would call this lying he countered by explaining it was actually stupidity.

"People should not ascribe to malice that which can easily be explained by stupidity. So it's like, just because I'm like dumb at predicting dates does not mean I am untruthful. I don't know. I've never made a mass-produced car. How am I supposed to know with precision when it's going to get done?"

Tesla did make 5,000 Model 3 vehicles in the last week of June. However, it did not regularly produce that many vehicles per week during the third quarter. Rather, the company averaged 4,300 model 3 cars per week during the quarter. Tesla has still not begun production of the $35,000 Model 3, but Musk said that it should be ready in five to six months.

Ramping up to the target of 5,000 Model 3s per week almost broke the company, Musk said during the interview.

"It was life or death," Musk said. "We were losing $50 million, sometimes $100 million a week, and we were running out of money."

It wasn't until the company created a third assembly line in a tent outside the Fremont factory that the company was able to ramp up production enough to meet its target.

"So those betting against the company were right by all conventional standards that we would fail, but they just did not count on this unconventional situation of creating an assembly line in a parking lot in a tent," Musk said.

Musk said this last-minute push with the tent increased the company's output by 50%.
