    Nobody uses hub motors on production EVs yet as far as I’m aware due to the much higher unsprung mass this creates. That is to say it is a bunch more weight flopping around on the opposite end of the suspension from the frame. This leads to handling, ride quality and reliability issues. Rivian does at least use a 4 motor system though.

      yeah that’s definitely a potential problem. Even then drive units aren’t particularly helpful. They do isolate half the drive train on AWD vehicles, but that’s about it.
