So I think this story sounds incomplete. I do not think it is mutually exclusive to say that the Bosch burner factory is shutting down and that 95% of all new cars sold worldwide are combustion engine powered. German labor is extremely expensive and German taxes are incredibly high. Welcome to the global economy.
I find it much more likely that much like everything else, the Chinese car market wants cars manufactured in China and that those China factories source from Chinese vendors. It's no different than the electronics industry.
