Almost. That Buick (and all conventional cars) uses the
engine - not an electric motor - to power the compressor.
The Prius compressor is motor-driven, but is that motor
powered by 12V? Traction battery dc? Inverter output ac?
Because it dissipates considerable power, it would be
more efficient to run it from HIGH voltage, and probably
ac after the inverter.
