Tesla is going to need to make a lot of cars if it's going to fulfill all those Model 3 pre-orders... 500,000 per year by 2018, to be exact. And it's making a big purchase to help it reach that lofty goal. The company is acquiring Grohmann Engineering, a German firm specializing in automated manufacturing. The buyout (which creates Tesla Grohmann Automation) should give Elon Musk and crew more of the expertise and systems they need for high-volume production not only at the Gigafactory, but elsewhere in the world. Grohmann will serve as the base for Tesla's Advanced Automation Germany facility, with more locations coming.
