> There are plenty of suitable MOSFETs available to buy today, retail. Some silicon carbide MOSFETs and drivers are near drop in replacements. Minor design revisions would be needed, new software, and lots of drivetrain stuff would need to be retested. There wouldn't be any systems-level changes. > They cost a few cents extra, but compared to delaying release by 12 months, that doesn't seem like an issue. Replacing such an important component in the car is totally a 12 month+ endeavor. Validations and tests are long, long things. Unless you're Tesla, and are grabbing whatever you can find in the nearest BestBuy and put that in the car that day. They should (and I expect they do) totally start work on alternatives, but that very likely won't bring them to market faster.
