First, what year model Cayenne?
You should know that the all-new 2011 Porsche Cayenne, no matter if its a base Cayenne, Cayenne S, Cayenne S Hybrid or high-end Cayenne Turbo have a single-speed transfer case with locking center differential, no low range off road gearing.
The older pre 2011 models have a more traditional heavy-duty two-speed transfer case with low range off road gearing and locking center differential.
It seems strange to compare a Cayenne SUV to a Raptor pickup truck. The Raptor is a true heavy-duty 4x4, and thus better than a Cayenne in terms of off road capability.
