Porsche New Zealand has just revealed details of the new Cayenne Turbo GT with a starting price of $342,000 with customer deliveries anticipated to begin in the first quarter of 2022.

With a 4-litre, biturbo V8 petrol engine producing 471kW of power and 850Nm (up 80Nm on the Cayenne Turbo Coupe), the Turbo GT is the most powerful SUV from Porsche.

The 0-100 km/h sprint is reduced to 3.3 seconds (0.6 s less) and a 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 especially 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 Coupe, 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. 

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.
