Does A/C effect the power?

I thought modern cars had a switch of some type that temporarily disengages the AC compressor when the car is under acceleration.

Does anyone else have this problem? It is starting to really bother me.

This is common on all cars.

The engine drives the a/c compressor when it is on. Takes 5-8 HP I believe.

Yes, but the "best" part is that in a Porsche you get the AC for both cooling and heating.....

Hi,

That's not just common to Porsche. Many cars (I might even say most) use the AC to dehumidify the air when in the Defrost mode to aid in unfogging the windshield...

Yes, but I would venture that few (might I even say, well, few) automatically turn on the AC for normal heater usage (non-defrost).

Hi,

I know what you mean, in Auto mode, the little Snowflake lights in the Display. I'm not sure that means the AC is energized though.

I have never actually checked it, but I don't ever remember hearing the Radiator Cooling Fans come on which is their default mode if the AC Compressor is operating. I'll have to check that one.

But, I can see the indicator showing in the display to alert the driver that this mode (Auto) will also control the AC operation...
