Tesla was building their cars from the ground up with a team that was learning things undoubtedly as they went along with all the new robotics, battery technology, heavy on electronics etc. Not sure on some things anyone could have told them what to do since they were essentially creating something so different with new parts and configurations. All of which they continue to seek to improve. Of course some car aspects would be old-school, but sure it took even Kuka reps a while to help Tesla program in specifics to Tesla's production line for their unique needs.
Yesterday we were looking at the underside of the hood of a friend's new Model 3. It had off-centered holes and my husband thought that was pecular to design it that way. He thought it was likely needed for the robots to pick up and handle the piece. When Sandy made the comment during the show something to the effect that cars have to be designed up front to work with robots (and the impression I got from what he said was that Tesla likely didn't--wondering if Munro has even seen videos of Tesla's production line), I thought I'm sure Elon, Franz and team did do just that since I think robotics has been the plan for Model 3 and future models all along from inception. And no way is Tesla going to rip out their Kuka robots and stick them outside the plant like it sounds like Munro told GM to do with theirs some time ago. Franz worked at GM, Volkswagen and Mazda previously and understands the manufacturing process in addition to design. Where I think maybe Munro's emphasis is to build the cheapest car, I don't think that is the main approach that Tesla takes to their cars nor do I think they are ignoring the cost factor. One of the early take-aways I had from learning about the Model 3 and future vehicles was that Telsa was working hard design-wise to simplify the car's build like in the wiring, the air vents, etc. I'm sure Musk has talked about this simplifiction to profitability many times in the past. To me Munro's talk (and the fact he and team were so far clueless on some of Tesla's design decisions) shows that he doesn't really get Tesla.
BTW possibly somewhere in the pre-show portion of the video they said that Munro bought 2 Model 3s for the teardown. Both would have been fairly early production vehicles. They even commented that both had been delayed in delivery because Tesla had to replace some parts or something. Better that Tesla catch a parts problem (maybe supplier's part) before delivery than deal with it later in a service bulletin or recall, but have to say I came away from Munro's discussion on this as it was a negative for the company.
Given the Model 3 is only a few months in production at this point, it's still working through supplier issues, and like fit and finish, and the hiring and training of more line workers, it's something that will just be part of growing pains. The addition to Tesla of Grohmann Engineering with 3 decades of highly regarded experience in this field is just another reason why Tesla will only get better over time. For what Grohmann brings to Tesla, this was from Wikipedia: "The product portfolio includes machinary for the production of microprocessors and memory chips, airbag sensors, power steering controllers, as well as systems for the production of door and roof seals and lithium-ion battery cells and entire battery modules. Among other things, the company manufactures robotics that are used in the battery and electronics production for Tesla, Inc. at the Gigafactory 1."
