It’s quite shocking to consider that, despite hikes of 20bhp and 37lb ft, which bring headline figures from the 4.8-litre V8 twin-turbo motor to 512bhp and 553lb ft, the Cayenne Turbo isn't the go-fastest version of Porsche's big SUV.
That questionable honour goes to the Turbo S with its 562bhp on tap. Similarly, the GTS has set the handling benchmark for Stuttgart's venerable 4x4. So where does that leave the Turbo?
For all that talk of the even more intense Cayenne models, and marginally improved economy for this car's facelift, let’s not confuse the Turbo with a moderate car. Considering one as your average family SUV - if you’re not specifically after raging performance - would be like browsing a howitzer catalogue for the occasional clay-pigeon shoot.
Ultimately, though, if you like cars, if you want a really fast one and you're contemplating a Turbo, then it won't disappoint.
The V8 is the star of the show here. Give it everything and you’re treated to a distant cacophony of turbo-whoosh and V8 warble, as you struggle to come to terms with just how rapidly the whopping 2.2-tonne mass is gaining pace.
It’s in part due to the contrast of the serene way you can tool about at normal speeds, helped by the smooth and intuitive shifts of the eight-speed automatic gearbox, but you’d never tire of the explosive way it hurtles up the road when you want it to.
Even so, while the engine can be effortlessly refined or ferocious at will, the ride is so seamlessly able to offer both comfort and thrills. Adaptive air suspension is standard and in its most easy-going setting there’s plenty of pitch and roll, yet (on the optional 21-inch wheels of our test car) there’s still a fairly harsh initial bump absorption that can make you feel a bit jostled over poor surfaces.
It settles over smooth-edged ruts and undulations, but it never feels as serene as you might hope, and of course the ride only gets more unforgiving the more dialled-up your choice of damper mode.
Still, most prospective Turbo buyers will consider the remarkable handling justification enough. There’s still some heavy body movement through fast direction changes, but between precise, well-weighted, consistent steering and feelsome brake and throttle responses, it’s easy to balance the Cayenne’s weight on the front tyres to bring a satisfying bite on turn-in.
