In an exclusive three-part interview, Tesla CEO Elon Musk speaks with Automotive News Publisher Jason Stein. In this first episode, the 49-year-old discusses a wide range of topics, including manufacturing challenges, the company's streak of quarterly profits and soaring market value. He also opens up about why the EV maker is so popular, getting more range out of future vehicles and how the federal tax credit program for EVs is putting Tesla at a ''significant disadvantage.''
