Let’s qualify that dig at the people who take something like the Cayenne GTS Coupe, activate Sport Plus mode, and then mash the accelerator down in densely populated areas in order to prove, ummm, what exactly?
If you take your new Porsche Cayenne GTS Coupe to a weekend autocross event or a track, or you’re out in the middle of nowhere on a road you know better than the lines on your face, this SUV’s intoxicating exhaust note is immensely pleasurable to a driving enthusiast. Employ this tactic anywhere else, and, well, you’ll spark irritation in almost everyone within earshot.
To paraphrase Mandy Patinkin’s Inigo Montoya character in The Princess Bride: “You keep making loud exhaust sounds in populated areas. I do not think people are impressed the way you think they are impressed.”
Moving on, the new 2021 Cayenne GTS Coupe has a twin-turbocharged 4.0-liter V8 under its low and short hood. Output measures 453 horsepower and 457 lb-ft of torque, and an eight-speed automatic transmission feeds the power to all four of the SUV’s wheels through a standard all-wheel-drive system.
Normal, Sport, Sport Plus, and Individual driving modes are available, accessed using a knob on the steering wheel. There is a Sport Response button in the middle of that knob, which is a quick way of temporarily dialing the Cayenne GTS Coupe to maximum performance when you need it. Additionally, there are settings for specific surfaces such as Gravel, Mud, Sand, and Rocks. Drivers can also raise the suspension for added clearance off-road.
Speaking of suspensions, in addition to a V8 engine, what makes the GTS a GTS is an adaptive air suspension with Porsche Active Suspension Management (PASM) and the sport exhaust system. To this, the test vehicle added the Lightweight Sport Package with a carbon-fiber roof, a carbon fiber rear diffuser panel, gorgeous 22-inch wheels to go along with a 30mm ride height reduction, and sexy center-mounted tailpipes, among other upgrades. Our evaluation car also had optional rear-axle steering. The point of all of this? Less weight, a lower center of gravity, and maximum grip. Good times.
Look at the Cayenne, and it is clearly a Porsche. Open the door and get in, and if you’re familiar with the automaker’s design ethos, you’d easily make the connection without the Porsche crest glittering on the steering wheel. After you twist the ignition switch on the left side of the dashboard, where Porsche traditionally puts this function, the uniquely Porsche experience starts to fade into something else. Why is that? During the daily drive, the Cayenne GTS Coupe smells, feels, and drives like any high-end European performance SUV.
That’s not a bad thing. But if you’ve driven a Porsche 718 or a Porsche 911, the entire experience, from walking up to the car to getting in, twisting the ignition, and setting off, is unlike that of any other vehicle. Once you’re underway, a Porsche sports car continues to deliver a special, undistilled dynamic character through the sound of the powertrain, the feel of the road, the immediacy of response to your input, and, depending on which version you’re driving, the raw fury of its performance.
A Cayenne Coupe isn’t like that. Until you get it out of the city, away from other people, and where you can drive it like you stole it, that is. Switch the Cayenne GTS Coupe into Sport Plus mode, and you’ll even forget that it's an SUV. Porsche claims the GTS Coupe accelerates to 60 mph in 4.2 seconds when using the Performance Start function. That might be accurate. Since we didn’t take it to a drag strip for quarter-mile runs, what we can tell you is that it's ridiculously fast for an SUV with an internal combustion engine.
Not only that, but the adaptive air suspension with PASM and the PDCC virtually eliminates the body roll and lateral motions that often plague even the highest performance sport/utility vehicles. And despite testing the Cayenne GTS Coupe on a hot late summer day in Southern California, the ceramic brakes performed flawlessly—as was expected.
Porsche Torque Vectoring Plus (PTV Plus) is also standard on the GTS, and in combination with rear-axle steering and AWD it clearly contributes to this Cayenne Coupe’s stunningly good real-world power, performance, and handling. During the daily drive, it might be hard to argue its superiority in comparison to a BMW X6 M or Mercedes-AMG GLE Coupe, let alone the corporate-cousin Audi SQ7, but we haven’t experienced this level of sheer, unrelenting competence on the mountain roads near Malibu in any other SUV.
If you’re wondering, the Cayenne GTS Coupe averaged 17.6 mpg on our testing loop, despite our best efforts to burn as much fuel as possible on parts of the route (an increasingly guilty pleasure). That’s better than the official EPA fuel economy rating of 17 mpg.
Also if you’re wondering, no, we didn’t take the Cayenne off-road. Porsche’s SUVs are more capable than you might expect when the pavement ends and the dirt begins, but with the test vehicle’s 22-inch wheels and performance tires, we decided to literally stick to the blacktop.
There is one other thing certainly worth mentioning. The test vehicle had optional thermally insulated and noise insulated glass, and the cabin was nearly silent at freeway speeds and downright chilly when traveling on days experiencing triple-digit temperatures. We recommend the upgrade.
