Toyota unveils two new EVs: the bZ3C and bZ3X

Because they don't actually want to sell any, but they'd like to stop all the bad press that Toyota is actively lobbying governments against EVs adoption to prop up their very profitable ICE engine cars.

They have an existing model (BZ3) and they just put X and C on the end. They did the same thing with the Prius derivatives a few years back.

Everybody replying to give me logical thought out answers is not addressing the real problem of why would Toyota name their cars such an awful, forgettable key-mash of a name.

Toyota doesn't typically name things with random hard consonants and numbers. But Subaru does, and they're a partner in Toyota's EV program.
