I have been posting a number of questions. I hope I have not worn out everyone's patience. What is driving the questions is what I am driving now, a 2009 Porsche Cayenne Turbo (not S). I spend a lot of time in CO, and while it performs quite nicely, it does lose a lot of power at altitude. Apparently, the X does not, and in some configurations is quicker 0-60 to begin with. Anyone have a sense of how the handling of the X would compare? The Cayenne is amazing in through the corners. I found this line comparing two 2016 models, X versus E Cayenne, which the X purportedly won, FWIW:
