Porsche has just unveiled a new version of its flagship SUV. With its 640 hp twin-turbo V8, which allows a top speed of 300 km/h, the Cayenne Turbo GT becomes the fastest Porsche SUV ever built by the Stuttgart marque. A simple remap would not have been enough to achieve this result. Porsche’s engineers have practically developed a new engine block (new crankshaft, turbochargers, cooling system...). Note also that the exhaust system is now made of titanium, which results in less heat dissipation and a significant weight saving. The body height of the Turbo GT has also been lowered by 17 mm (compared with the Turbo), the air suspension has been stiffened by 15 % and every chassis element has been specifically tuned for optimum performance: PASM, PDCC, steering, rear-axle steering. Finally, at the heart of the 22-inch wheels, carbon-ceramic brakes are fitted as standard to reduce unsprung mass. The result: a significant weight saving and, therefore, higher performance.
