Is it model or plarform sales targets?
Maybe 240k sedan format sales per year on the platform.
Wow Toyota blatantly copying Tesla, big brain moves there.
I have some experience with casting heads and blocks. The more material, the more difficult it is to control porosity. How do they confirm porosity in a gigacasting? 100% scanning in areas that are expected to fracture in a certain way during crash testing? Or lot release with cut checks? With sheet metal making up the structure of a unibody, it's pretty easy to visually confirm if the welds are in place and if the sheet metal is the right shape/size with online gaging. Is that possible with gigacasting? Its definitely a new/different challenge. With blocks and heads, they either leak or they don't. The wall thickness of a cylinder block water jacket doesn't change the crashworthiness of a vehicle because that entire assembly breaks at the engine mounts. Suspension pickup points with high porosity on a large, cast subframe could have much lower strength and thus fail differently than how the crash testing says it should.I'm not convinced yet that the giga castings have any benefits to the buyer/consumer. They are great for production yes, maybe even save money. But, in the. event of an accident who pays? Insurance. So people's insurance rates will be much higher on "cast" vehicles in the long run. Repair bills will be huge and repair times might even be terrible because can you imagine shipping and auto body places replacing such large components?
