The Cayenne was the Porsche for people who didn't like Porsches. It was a status symbol SUV when there was no one else in the market. The X5M is just a souped up X5. The average person will never notice the difference between an X5 and X5M, something rich people looking to flaunt their money aren't going to like.
Also, put down the crack pipe. Driver talent being remotely equal, an X5M is not hanging anywhere near a Gallardo on the track. Not even the 6 year old original Gallardo which set a time of 1:25.8 in the wet. That's a 2.4 sec advantage which is a bigger gap than the X5M beat a Volkswagon Golf R32 MkV. The current gen Gallardo posted a time of 1:19.5.
