- CarVac 6y agoThey went from individual stampings welded together to very large die-cast parts.
- pmorici 6y agoLarge casting machine. See Sandy Munro’s model Y tear down videos for a look at the casting
- Obi_Juan_Kenobi 6y agoTesla is going ham with thixotropic aluminum casting. Big-ass machines, big-ass castings, no heat-treat. The goal is to get that down to a single casting. Not only does this simplify production further, but you can do it with no machining afterwards, no datums, nothing. You just tap the holes and put it together. https://www.youtube.com/watch?v=pih4kU6yvz8 https://www.youtube.com/watch?v=pih4kU6yvz8 The Y is realizing a lot of things they were promising with the 3. It's a much more exciting vehicle from a production standpoint.
- Tuna-Fish 6y agoCasting. Note that the Model 3 rear is a bit of a pathological case. In his teardown, Sandy Munro had a lot of good things to say about other parts of the car, but considered the tail end to be a horribly engineered overly expensive mess. So it looks so good because they started with the unambiguously worst piece in the car, and made it really good.
