The Cayenne Turbo GT is the track-focused flagship of the range, built exclusively on the lowered Coupé body. Its front-mounted 4.0-liter twin-turbocharged V8 produces 650 horsepower and 626 lb-ft of torque, driving all four wheels through an eight-speed Tiptronic S automatic. Porsche quotes a 0-60 mph time of 3.1 seconds with the standard Sport Chrono launch control and a 189-mph top track speed. With test driver Lars Kern at the wheel, a Cayenne Turbo GT set the SUV lap record at the Nürburgring Nordschleife on 14 June 2021 with a time of 7:38.925, certified by an independent adjudicator. It rides on standard 22-inch wheels with Pirelli P Zero Corsa tires.
