I hope the new systems are better than the old ones! When the daughter was going to UofA (Go Cats!) I spent time down there in a 7 series and the A/C was not quite useless but next to it as far as handling those 120 degree days! Sold the 7 and bought a Tahoe which I needed for other reasons, but the pleasant surprise was the GM A/C which would chill beef even on the hottest days! Also had airport rental Buicks back then that were also light years better than the 7 series in the A/C category. If you want a benchmark to check the X3 A/C performance against go to the Chev/GMC store and test drive one of their trucks on a 120 degree day back to back with the BMW.
