Tesla, despite moving its corporate headquarters to Texas, has announced that it still considers California to be its global engineering home base. The electric vehicle (EV) company will use a former Hewlett-Packard building in Palo Alto as its new engineering headquarters, which CEO Elon Musk said would be “effectively a headquarters of Tesla.” Musk added that the company’s plant in Fremont, which it bought in 2010 from a joint venture of General Motors and Toyota Motor Corp., will increase production to over 600,000 vehicles this year.
