The biggest issue with the Cayenne was the bastardisation of a sports car brand - and the idea of putting ludicrous amounts of power into an incredibly expensive and inefficient 4x4. And it turned out that there was a customer for this kind of car, and they could all be found on the school run. The Cayenne is still a monstrosity. However so many other premium brands have brought out a clone - it's become almost common place now.
With such saturation of the market, it's like BMW are choosing to design something absolutely horrific, just to stand out from the crowd.
