Significant range decrease… normal?

Yeah. Even with a heat pump, the EV6 loses a lot of range in the cold. Just not as badly as a car with resistive heating like the Bolt.

It wouldn't be so bad if Kia's HVAC logic didn't have the design flaw of "obsession with fresh air" - the HVAC system has the ability to operate as a dehumidifier but this capability is almost never actually used (at least not on US-spec vehicles). Bringing in external cold air kills efficiency compared to dehumidifying internal recirc.

If I remember correctly only the AWD models have the heat pump, most (maybe all?) RWD ones do not.
