Can't be too terrible. It's a base Porsche Cayenne with the steering and chassis tuning biased towards the "U" in SUV instead of the "S" In other words, the Porsche version is a SPORT Utility Vehicle and the Volkswagen is a Sport UTILITY Vehicle.
Unless there is another engine that is 3.6 liters, it should be the same 10° VR6 that powers the Cayenne. Timing chains can be troublesome on some but not nearly what they were on the 12V VR6es
...oh, and it doesn't have the Alcantra headliner like the Cayenne or Q7. Nothing against the Volkswagen's interior. It is actually quite nice. I particularly liked the Brown and Dark Tan interior.
