They use different systems... of which I am no expert. I am going to assume that Porsche's "premium" system (not on Cayenne Diesel but on the S, GTS and Turbo) is more sophisticated and lighter than BMW's. However, its "basic" system (found on Cayenne Diesel) is inferior.

Keep in mind that tires and ground clearance, not the ultimate sophistication of the AWD system, make all the difference when the pavement ends.
