Yeah, not just GM, everyone. I was surprised when Rivian didn‘t use a heat pump for instance. They had, what, 8+ years of engineering time before production?This was my thinking as well when they [GM] came out with the Hummer 2+ years ago to premier their new battery platform. After thinking about it a bit, I just don’t think they have the engineering talent to pull it off.
You listen to the engineers they have on slick Ford and Rivian marketing videos and you go, ok, that sounds like an ordinary competent engineer. You listen to Tesla ones, and you go, that person’s a rockstar.
Speaking of, Tesla’s heat pump (and uber integration) gets the spotlight in Teslas latest 3 minute video (which I’m sure has been posted here already).
