RR interior is nice indeed. But performance is miles away from Cayenne and BMW X.

X6 is not a full SUV, you should compare it to the RS6 or Panamera.

I am still waiting on real world compare of the X5M with the Cayenne (remember the ML63AMG?). The killer would be if the X5M gets the third row, no competition then!

 

Until proven otherwise, the Cayenne is still king. Not bad for a 6 year old chassis!
