The A/C with a separate motor is more efficient as the compressor can be driven at the correct speed instead of up and down at the engine speed. The cooling system in most EVs also cools the battery when needed. The cooling system works quite well using about 5% of the range in hot conditions. EV can be pre-cooled or pre-heated before you drive using utility power if connected. Even inside your closed garage.
I have driven the Toyota Prius when they first came on the market years ago. I liked it and it ran fine with no problems, even in the summer.
If, there is nothing (NO engine) but an electric motor to make these new electric cars go, what powers the A/C and on these days here in the South with 90 percent humidity and 90 degrees?
I guess I am just old school and don't understand how this kind of setup could be of value for anything other than driving to the market and back.
