In an interview earlier this year, CEO Elon Musk also said that Tesla is moving to an aluminum casting design instead of a series of stamped steel and aluminum pieces for the Model Y body: Yesterday, we reported on how Tesla is working on a revolutionary new wiring architecture to help robots build upcoming cars like the Model Y. We have been reporting on how Tesla plans to simplify the design of its future vehicle platforms and achieve greater automation in the manufacturing process. Tesla is working on several significant manufacturing improvements for the Model Y production program and it includes building a giant new casting machine to produce a big part of the Model Y frame in one single piece.
