Slightly more extravagant than the X5 and the ML - the Porsche Cayenne Turbo is for those who want an 'Experience' whilst travelling to an experience. 0-60mph in 5.6secs and a top speed of 165mph what better terrain than the Mountains and Valleys in which to test this amazing 4x4. (Warning - this is not your cue to drive like a mad Frenchman).
