Elon Musk shows off Model 3 production line (video)

For the first time ever, Elon Musk provides an exclusive look at the production line that builds the Model 3 cars. The electric car maker has been struggling for a while now to ramp up production of its mass-market car. Even though skeptics are once again predicting doom for the company, Musk believes things are looking up and predicts Tesla will be profitable and cash flow positive in the third and fourth quarter of this year.

The pioneering electric car company Tesla has suffered a series of very public challenges since the beginning of this year. Its high-profile CEO Elon Musk called this a period of "production hell." Most of the troubles revolve around the company's Model 3 sedan, its first mid-priced, mass-produced electric car.
