For the new Turbo GT, Porsche has thoroughly reworked their 4-liter twin-turbocharged V-8 powertrain with robust internals like camshaft, timing chain, pistons, connecting rods, and more, allowing it to produce an impressive 631-hp and 626 lb-ft of torque. With almost 100 hp more than the standard Cayenne Turbo, the GT blitzes the competition, reaching 60 MPH in just 3.1 seconds.
However, despite the power bump, the Cayenne Turbo S E-Hybrid is still the most powerful model in the lineup, packing 670 hp. Porsche has also updated the 8-speed automatic transmission for quicker shifts, allowing it to walk past all the other Cayenne models including the S E-Hybrid, even with the 39 hp power deficit. Other notable drivetrain upgrades include a water-cooled transfer case and a center-mounted titanium exhaust, developed specifically for the Turbo GT model.

Thanks to the lighter chassis and upgraded performance, the new Turbo GT is the fastest Cayenne ever, reaching 60 MPH in just 3.1 seconds, which is 0.7 seconds quicker than the regular Cayenne Turbo. Quarter-mile timing is also impressive at 11.6 seconds. While the new 2022 Porsche Cayenne Turbo GT Coupe is a lot more expensive than both the BMW X6 M and Mercedes-Benz AMG GLE 63 S, it matches the performance of the Lamborghini Urus, which costs substantially more than all of these machines.
How does the 2022 Porsche Cayenne Turbo GT Coupe Handle?
To handle the extra performance, the Turbo GT gets a myriad of chassis and suspension upgrades. Compared to the regular model, the Turbo GT gets specifically tuned components like adaptive dampers, steering, active anti-roll bars, and more to keep the body lean in check through the corners. The wheels are also bigger at 22-inches and measure almost 1 inch wider than the standard model with increased negative camber.
The GT also gets Pirelli P Zero Corsa tires which were specifically developed for it. Other notable additions include standard carbon-ceramic brakes with 17.3-inch rotors at the front and 16.1-inch at the rear. With all these upgrades, the GT can easily put some purpose-built sports cars to shame out in the track, placing it up there with the likes of the excellent Lamborghini Urus. In fact, the Cayenne GT handles as well as a sports sedan, which is the highest praise for a large SUV.
