Analysts share a behind-the-scenes tour of Tesla’s Gigafactory

Can Tesla produce Model 3s in volume, and make a profit? That’s the question of the day (or maybe, of the century). Investment management firm Worm Capital (among others) believes that the answer depends on how efficiently the company is able to manufacture its battery packs, and it recently sent a team to visit Tesla’s… Read more »

Tesla acquisition of German engineering firm should help with production ramp-up

Tesla has announced plans to acquire Grohmann Engineering, a German company that the California carmaker called “one of the world leaders in highly automated methods of manufacturing.” Grohmann currently has around 700 employees, and had revenues of 123 million euros ($136 million) in 2015. It has developed battery production lines for several automakers. The company… Read more »
