A couple observations--

You live in Albuquerque. So your air conditioner is mostly just cooling the air, not dehumidifying it.

What color is your Audi? I have begun to notice a difference in cracking the windows between my navy Escort and my husband's gold Malibu.

A light colored car in a dry enviroment is likely going to feel more comfortable than a dark colored car in a muggy enviroment, all other things being equal.

(Note: the navy escort doesn't have working AC, so I've very aware of the different combos of window height, speed, fan setting, and enviroment in keeping myself cool.)
