In terms of drive and performance, the cayenne s and the cayenne turbo are not so different. They have the same engine apart from the fact that the turbo has a turbocharger instead of a supercharger. The turbo's also come with higher spec as standard then the s, hence the price. IMO: The only cayenne that does not have enough power is the cayenne v6 or the diesel. I am not shore which one I would go for though... but since it's an BMW X forum, the X6
