I have the warm weather package in my car (dual zone AC and thermal glass). However, I thought I once read that the Cayennes got engine modifications for the hot weather market. Is this the case and what are they?

 

I'm pretty sure this is not true. All US cars are equipped with the same engines and for the most part it gets as hot or as cold as 99% of anywhere else in the world.

 

no engine mods, all engine should be excatly the same.
