Some systems could also implement it into the existing A/C system since heat pumps are pretty much just A/C in reverse. You just need to flip the evaporator and condenser around, along with controlling some valves.
Weight or mass and or its distribution are big factors, made worse for BEV by the battery's energy density, magnets & coils.

My general thinking is to reject nuance that serves the grand touring/luxury mindset of people that buy expensive vehicles. Heat pump gets filed here.

The Taycan was on an okay path with a two speed gearbox, and not as much range weight.

Shrink the motors for the desired power until the coils start to fry and need gearing for lower speed/cooling flow.

Someone posted a joke meme with a Tesla towing a fuming generator. Think about it and it's not.

Build a generator powered charging rig/trailer that can swap between multiple battery packs. Run a lighter pack at track for the full voltage curve and swap it. Kill their cycle lives and buy replacements. Every year or every few.

Also ignoring unconventional ideas that might make an EV faster. Like tandem seating, or single seat.

I want an unapologetic gasoline Camaro to stay.
The EV topic is getting tired for me. Sorry for the delayed reply.
