As the title says, does the 4-zone climate control have a higher BTU rating (to handle higher cooling loads)? I am trying to understand the justification for the option. If it allows rear seat passengers to have individualized climate settings, I will pass. If it has higher BTU rating for the A/C, I am all in.

Thanks in advance.

Schnave on the Cayenne (9YO) forum might know. I think he said there is additional coolant in the 4 zone climate control on that model. I'm not sure if that translates to more BTUs of cooling though.

If you scroll down to the 4 Zone Climate Control post, there's no definite answer but the Cayenne uses 25% more refrigerant. This implies to me that the four zone system has a higher BTU rating. I have it and like it a lot.
