A Tesla Motor Inc. Model 3 vehicle is displayed outside the company's Gigafactory in Sparks, Neveada, U.S., on Tuesday, July 26, 2016. Tesla officially opened its Gigafactory on Tuesday, a little more than two years after construction began. The factory is about 14 percent complete but when it's finished, it will be about 10 million square feet, or about the size of 262 NFL football fields.
