Porsche Cayenne Turbo GT vs Aston Martin DBX707

Porsche's new Cayenne Turbo GT is a formidable contender in the world of high-performance SUVs. With 631bhp and 627lb ft of torque, it outperforms its predecessor, the Cayenne Turbo coupe, by 89bhp and 69lb ft. Its impressive numbers continue with a 0-62mph time of 3.3 seconds and a top speed of 189mph. In fact, it even beats the fastest hot hatches around the north loop of a specific German race track, completing the 12.9-mile lap in just 7 minutes and 38.9 seconds.

But why would anyone want a 2200kg SUV that has been fine-tuned by Porsche's GT department, known for their expertise in GT3s and other high-performance cars? The answer lies in the demand for ultra high-performance SUVs like the Lamborghini Urus, Aston Martin DBX, and Range Rover Sport SV. Porsche wants to cater to this fervent market and grab a slice of the pie. Unfortunately, if you're in Europe, you won't be able to get your hands on a Turbo GT, as Porsche no longer sells it in this region.

The development of the Turbo GT goes beyond a few laps around Weissach and some engine management code updates. The twin-turbocharged 4-litre V8 has undergone a comprehensive overhaul, including a new injection system and upgraded internals for the turbos. The engine components, such as the crankshaft, con-rods, pistons, and timing chain, have either been customized or thoroughly redeveloped for the Turbo GT.

Not only has the engine been enhanced, but the chassis has also received bespoke modifications. The Turbo GT sits 17mm lower than a Turbo and features re-engineered core chassis components. This includes improvements to the air springs, active dampers, and calibrations for all the chassis systems. The three-chamber air suspension has a 15 percent increase in rigidity, and the electric power front and rear axle steering have new tuning. The active anti-roll bar system has new software, the front axle has bespoke bushes, and the torque vectoring allows for higher diff lock ratios. The front wheels are wider, and there's more negative camber, while the 22-inch Pirelli P Zero Corsa tires are specifically designed for the Turbo GT. The carbon-ceramic brakes have also been fine-tuned to match the SUV's size, weight, and performance.

All these changes result in an impressive performance SUV that is not only powerful but also offers a refined driving experience. Despite its weight, the Turbo GT feels natural and precise on the road, unlike other performance SUVs that often sacrifice finesse due to their bulk. It can be compared to Aston Martin's DBX in terms of precision and driver engagement, but the Turbo GT leans more towards the sports car side of the spectrum.
