Tesla CEO Elon Musk is revealing his grand ambitions for a multi-vehicle lineup with this move. The Model X, with its exotic falcon-wing doors and highly touted mashup of "SUV and minivan," will be built on the same assembly line as the award-winning Model S, Bloomberg reports.

This will crank up the plant's output by 25%, if all goes according to plan. Tesla plans to install $100 million in new robots so it can construct both cars at the same time — no easy task for a startup automaker that has so far only managed to build one vehicle at a facility that was formerly shared by Toyota and General Motors.
