Regardless of what you think of the Cayenne, it's coming and the world has to be prepared for it. But let's try not to worry so much about it; it's not just another 'join-the-band-wagon' SUV simply to appeal to the sport-ute masses. Think about it, it IS Porsche we are talking about here. Press released specifications include entry level 4.2L V-8 with 337 hp, 4.2L V-8 twin turbo with 449 hp. Unconfirmed but, there may also be a high performance (as if the V-8tt wasn't high enough) V-10 engine from the Carrera GT on its way, but redone to put out more torque. Recent developments are announcing that the Cayenne will not use the VW 3.2L 240hp V-6, which will power the model clone, VW Colorado SUV.
The simple fact that Porsche is using their own performance oriented engine erases all the 'me-too'ness common in modern SUVs. Secondly, Porsche has begun to promote the "Tread-Lightly!" campaign and has deemed their upcoming SUV to be used primarily for the road; the Cayenne is designed to show Porsche's road handling prowess as well as power. And who cares if it doesn't fare well off-road? Not many people take their exotic SUVs off public roads anyway.
