Kia and Hyundai also use heat pumps.

The jury isn’t out. I found the fastest link I could. It’s a heat pump just like every other ev now except for a couple. Why don’t you do some of your own research, expanding relentlessly with bad info from one crappy article is a complete waste of time. The heat pump in the RAV4 can heat and cool the battery while heating and cooling the cabin, including scavenging heat from the engine coolant or adding it to the coolant when needed. None of this is new or a mystery. Tesla does the same thing with their octovalve, I assume Hyundai/Kia act similarly. You have a budget ev designed by the Koreans using an existing ICE platform, the Silverado and any other dedicated EV platform will be light years past your hatchback, there is no point in comparing or expanding on your own ignorance.
here’s some more I just found, a step above a consumer electronics blog.

Silverado is ultium, they all share the same batteries and technology. Every heat pump system can scavenge heat from the condenser or the evaporator, that’s how they work, maybe the terminology is different I don’t know. The new tech in automotive heat pumps is scavenging heat from batteries and motors too. This is what GM wants to talk about, I think most would assume that the cabin could be heated from external air because that’s how ALL heat pumps work, on everyone’s current EVs including my wife’s.*
*except for below 14 degrees, same as all heat pumps. My wife’s uses the engine in such a scenario, I assume GM will have resistive heat, the teslas just have no heat until the motors get warm or none at all as discovered last winter by Canadian Tesla owners… sucks
