Now, the 2021 Porsche Cayenne Turbo Coupe – with its less practical cabin but more stylish sloping roofline – also needs to contend with the new Audi RS Q8 and Lamborghini Urus. Porsche is confident that the Cayenne Turbo Coupe still has what it takes to fend off tough rivals, though, because it hasn’t introduced many changes this year. That means that a 541-horsepower twin-turbo V8 remains and can see this SUV annihilate the 0-60 mph run in only 3.7 seconds. At over $130,000, it’s a very expensive privilege, but the Cayenne Turbo Coupe’s agility remains astounding for such a heavy beast. It’s also got a great cabin and looks the part. Rivals may be closer than ever before but judged purely as a performance SUV, the Cayenne Turbo Coupe might just hang onto its crown.
The regular Porsche Cayenne Coupe range (reviewed separately) has been bolstered by the addition of a GTS model this year, which means that the Cayenne Turbo Coupe is no longer the only V8 in the lineup. However, the Turbo remains the most powerful non-hybrid derivative and otherwise enters the 2021 model year without any major changes. This isn’t a great surprise since the model is still a fairly fresh arrival on the market.
Although nearly identical to the regular Cayenne from the front, the Cayenne Coupe has its own personality with its coupe-like roofline and sportier rear aspect. It’s definitely the more fashionable choice between the two and, in Turbo specification, even more so. This model has 21-inch Cayenne Turbo alloy wheels, which partially conceal brake calipers painted in white. The Turbo Coupe comes standard with a fixed panoramic roof, an automatic rear hatch, a fixed upper wing, and LED lighting. The twin dual-pipe Turbo tailpipes in brushed stainless steel hint at the towering performance on offer.
The Cayenne Turbo Coupe has a length of 194.5 inches, a width of 86.4 inches including the side mirrors, a height of 65.1 inches, and a 114-inch wheelbase. Overall, the Turbo Coupe is very similar in size to the regular Cayenne Turbo – it is almost an inch lower, though. With a curb weight of 5,024 pounds, it weighs 32 pounds less than the Cayenne Turbo. If, for some bizarre reason, you do decide to head off-road with your Cayenne Turbo Coupe, you’ll find a maximum wading depth of 20.8 inches and a ground clearance of up to 9.6 inches with the air suspension in its highest setting.
The Porsche Cayenne Turbo Coupe uses a 4.0-liter twin-turbocharged V8 engine producing 541 horsepower and 567 lb-ft of torque. It’s paired with an eight-speed automatic transmission that directs power to all four wheels. The combination endows the Cayenne Turbo Coupe with epic acceleration – it storms off the line and pushes you firmly back in your seat, with 60 mph coming up in only 3.7 seconds and a top speed of 177 mph reached not too long after that. The V8 perhaps isn’t as soulful as some older, naturally aspirated Porsche units, but it isn’t entirely devoid of character, either. More importantly, it responds instantly to throttle inputs and the gearbox goes about its business without you even noticing. But as fast as the Porsche is, both BMW and Audi achieve the same 0-60 sprint time with the X6 M and the RS Q8, respectively, and for less money than the asking price of this Porsche. The Cayenne Turbo Coupe isn’t all about straight-line speed, though, as it also has a good 7,700-pound maximum towing capacity.
Porsche doesn’t seem to know how to engineer a second-rate chassis and it isn’t about to start with one of its halo SUVs. The Cayenne Turbo Coupe isn’t just wickedly quick, but it’s got the handling and crisp responsiveness through the steering wheel to match the engine’s power. While it isn’t a 911, the Cayenne feels a lot lighter on its feet than its weight would lead you to believe. With power sent to all four wheels, there is plenty of grip to exploit before the limits of adhesion are breached. Feedback through the steering wheel prevents the Cayenne from feeling overly computerized, despite all the tech working hard to keep everything in check, but it still isn’t the most involving of drives. The adaptive air suspension manages to provide a supple enough ride when cruising and the Porsche Active Suspension Management (PASM) system keeps body roll at bay. Rear-axle steering is a $1,620 option that improves maneuverability at low speeds, and traction can be enhanced by speccing the Porsche Torque Vectoring Plus system. With or without these extras, the powerful Cayenne Turbo Coupe is a joy to drive.
