Henry the BMW system is different than the AV(P)G systems -- not to say its any worse or better just different. All the systems are the same in that they provide four wheel drive of course, and share other features as well. As far as the Cayenne/T-egg-Q7 diesels go, I believe that the diesel drive trains retain the prior system with the locker low range and weight penalty -- of course that adds off road capability for those insane enough to run the Rubicon with their new diesel Cayenne! However Mike would know the definitive answer -- having used one off road up in the far North.
