Promising up to 631bhp from a tweaked version of Porsche’s twin-turbocharged 4.0-litre V8 petrol engine, the as-yet unnamed model will be sold exclusively in the Coupé bodystyle and sit above the existing Cayenne Turbo in the line-up.
A focus on weight reduction will make it significantly lighter than the Cayenne Turbo S E-Hybrid, which produces a combined 671bhp from a petrol V8 and electric motor but weighs 2535kg.
Ahead of its official reveal, we were invited to drive a prototype representative of the production version, albeit with some light disguise covering various exterior details, including a reworked roof spoiler and new wing elements. The 22in Neodyme wheels are a further giveaway to the new model's added performance potential.
Inside, the changes are more subtle. Up front, there is new Alcantara trim with contrasting stitching, sports seats and a thicker-rimmed sports steering wheel with a Sport Response button that allows you to select the various driving models via a rotary controller. In the rear, the three-seat bench is replaced by a pair of individual seats, giving the interior of the new model a more distinct 2+2 character.
Heading out of Stuttgart, the remarkable thing about the uprated Cayenne is just how unremarkable it feels in everyday traffic in Comfort mode, given that you expect an SUV that has been honed to run records at the Nürburgring to be hardcore at all times. The adaptive air suspension features dampers that are 15% firmer than today’s model. And, yes, there is a purposefulness to the way it rides, but precious little else that would convince you it couldn’t be used every day.
