We do know this much because we recently put a photographer on his factory floor in Fremont, California: He's going to be cranking up the output to an unprecedented level, using a series of high-tech robots, lasers and other cool stuff you'll see below. Tesla recently asked Fremont's planning commission to let it nearly double the size of the 5.3 million-square-foot facility. That's so Musk can churn out 1 million cars a year by the end of 2020, a Tony Stark-size promise and a grand leap from the 50,580 he rolled out last year.
