From what I read months ago, Tesla uses a 45 volt compressor or about 45 volts. No idea how it works whether its staged or uses different voltages etc. Its never been detailed for some odd reason. Other manufactures have not detailed the hvac either. That alone should raise a red flag.
A heat pump would work for ac just fine but in the heat mode, it would be limited to outside temperature and would need electric backup and use it after temps drop below 50f or about. The other issue is humidity. All modern cars use the ac to reduce humidity levels in the cabin for safety and comfort. To do all that with a heat pump doesn't sound very easy but may have been accomplished.
Lou, the hybrid really does not accomplish what I am putting fourth. Plugin hybrids are still hybrids which is an electric assist of a combustion engine. Thats not what I was suggesting however is was an interesting step in a better direction which again was something that was skipped over. I consider that design more of an eco. (engineering change order) Plug in battery ranges are very low or were the last time I looked.
If the goal of electrics is to save the planet, then I would think EVs should be more practical and manufaturers should be clearer on the functionality.
The Tesla is obviousy the beast in the industry but so is the price. Last I looked the model S dual motor was rated at about 425 miles. Thats pretty good even if you factor in the hvac issues. The problem with that is at 60-70k price. It prices out of most peoples budget and probably won't save any money to the consumer once the batteries need replacing. You cannot tow it either and its quite heavy.
