New Sporting Hero From Porsche: The Cayenne Turbo GT
Porsche rounds off the Cayenne model range with a sporting hero: consistently set up for maximum performance and handling, the new Cayenne Turbo GT combines outstanding driving dynamics with a high degree of everyday usability.
Its 471 kW (640 PS, Cayenne Turbo GT: Fuel consumption combined 11.9 l/100 km (NEDC), Fuel consumption combined 14.1 l/100 km (WLTP), CO2 emissions combined 271 g/km (NEDC), CO2 emissions combined 319 g/km (WLTP)) four-litre biturbo V8 provides the basis for superb driving characteristics. With 67 kW (90 PS) more than the Cayenne Turbo Coupé and maximum torque of 850 Nm (an increase of 80 Nm), the 0-100 km/h sprint is reduced to 3.3 seconds (0.6 s less) and top speed is now 300 km/h (an increase of 14 km/h). With even sportier lines and available exclusively as a four-seater Coupé, the Cayenne Turbo GT comes with all available chassis systems fitted as standard and performance tyres developed specially for this model.
The powertrain and chassis also have a unique set-up specifically tuned for the Cayenne Turbo GT. The result is a harmonious overall concept with superb racetrack capability. This has been proven by Porsche test driver Lars Kern, who lapped the 20.832 km Nürburgring Nordschleife with the Cayenne Turbo GT in a time of 7:38.9 minutes, setting a new official SUV record.
Compared to the Cayenne Turbo Coupé, the Turbo GT rides up to 17 millimetres lower. Based on this, both the passive chassis components and active control systems have been re-engineered and optimised for handling and performance. They also feature specific calibration to guarantee perfect interaction between them. As an example, the rigidity of the three-chamber air suspension has been increased by up to 15 per cent, and the damper characteristics of the Porsche Active Suspension Management (PASM) as well as the application of the Power Steering Plus and rear-axle steering have also been adapted. The Porsche Dynamic Chassis Control (PDCC) active roll stabilisation system now operates with performance-oriented control software.
The result is even better roll stability and roadholding, as well as more precise turn-in behaviour at higher cornering speeds. In line with this, the Porsche Torque Vectoring system allows higher torque bias ratios. The comprehensively optimised front axle also improves handling. Compared to the Turbo Coupé, its front wheels are an inch wider and negative camber has been increased by 0.45 degrees to give the new 22-inch Pirelli P Zero Corsa performance tyres, specially developed for the Turbo GT, a larger contact patch. Braking duties are performed by the standard-fit Porsche Ceramic Composite Brake (PCCB) system.
