Available in the coupe bodystyle only, the Turbo GT isn’t just about outright power, which brings us to its Nürburgring lap time – because how could you launch the fastest Cayenne ever without taking it to the ‘Ring? Porsche test driver Lars Kern, the same man who’s piloted the GT3, GT3 RS and GT2 RS to numerous records, took the Turbo GT around the Green Hell in a scarcely believable 7 minutes 38.9 seconds.
The ride height has been dropped by 17mm, while the car’s various control systems, the power steering and rear-wheel-steer have been overhauled to match the increased performance. Porsche gives the example of the three-chamber air suspension which is now 15 per cent more rigid. The Porsche Dynamic Chassis Control roll stabilisation system has been tweaked to go with additional tyre grip and sharper turn in, while the torque vectoring system now allows for higher locking ratios.
Additional grip comes from specially developed Pirelli P Zero Corsa tyres, and paired to those are front wheels that are an inch wider while the negative camber has been increased by 0.45 degrees. The brakes have been tweaked to reduce fade and unsprung weight and improve performance, says Porsche, but exactly how they differ from the Cayenne Turbo’s brakes remains unclear for now.
