Who's better to define what's a "real porsche" other than Porsche AG, so heres what Porsche had to say about the CayenneA Real Porsche
The Cayenne is the REAL Sports Utility Vehicle (SUV) that out performs many so called sports cars on the road(not to mention its off-road capabilities) whos physics defying abillity was recognized by racing drivers, motor journalists, and car enthusiasts world wide.
For example "GT Purely Porsche" Magazine once quoted "More than anything it feels like a proper Porsche: a car that takes the company's unparalleled knowledge of performance car development and applies it to an altogether different discipline" (Cayenne Turbo)
If Porsche developed the Cayenne to be the world's best SUV, and it did, in the tradtion of Porsches pureness, then I say a Porsche SUV is a real Porsche. Just as a Porsche convertible is a real Porsche and a Porsche 911 with Tiptronic is still a real Porsche.
