On this episode of Wide Open Throttle, Jessi Lang reports from the Tesla facility on the day of the long-awaited rollout of the Model S, the world's first premium all-electric sedan and the car on which the company's future now depends. Then, Motor Trend Technical Director Frank Markus gets exclusive one-on-one time with Tesla CEO Elon Musk and Chief Designer Franz Von Holzhausen as he tours the Tesla factory and finally gets behind the wheel of the car that Tesla is hoping will galvanize the world's transition from internal combustion engines to electric mobility.
