Any large heavy vehicle with a gas engine will have a hard time with MPG . My wife's 2010 Volvo XC90 weighs about 4500 pounds so similar to a Cayenne . Ours is a 3.2 straight six and the best we have achieved on the highway has been 20.6 per the on board computer . And it is a front wheel drive not all wheel .
I think a Cayenne diesel would be a sweet rig but they are much harder to find .
