I'm actually not sure in terms of car AC. Local wisdom says that on hot days your AC will sap up to 10 HP from your engine. Not sure how accurate that is.

Looking around on Telsa forums and the like, I'm seeing numbers between 1 and 3 kW. My house's mini split AC unit draws around 9 amps (according to documentation, anyway), so around 2 kW. Actual numbers seem to be closer to 3 kW in the summer.

I currently have my Tesla plugged in to my 6kw home charger, with the AC blasting, and the range isn’t increasing, leading me to believe that the AC running 100% takes around 6kw.

hmm, gets me wondering if that's why my car can't climb hills when on AC.

That may be part of it. Most (all?) newer cars will automatically cut off the AC pump under heavy acceleration.

"Hang on, I'm hitting the turbo button." (turns off AC)

Every car with voice control should recognize “divert life support to propulsion" as a command to turn off engine-driven AC.

Oh man passenger reactions would be so awesome. Suddenly the driver just says "divert life support to propulsion" - and the passengers are like "WAIT WHAT LIFE SUPPORT?!"
