2020 Porsche Cayenne Coupe vs Audi Q8 Spec Comparison

The excitement and controversy around the new Porsche Cayenne Coupe has been palpable ever since Porsche announced it officially yesterday.

The 2020 Porsche Cayenne Coupe has upset a lot of people. They can live with two SUVs and a sedan, but now a “four-door coupe” Cayenne? Enough is enough, right? Wrong.

A new Coupe version of the Porsche Cayenne makes sense and we need not look any further than the BMW X6 for proof. BMW launched the four-door coupe mid-size SUV segment 10 years ago with the first-generation X6 and has had nothing but success with it. Why that is doesn’t matter.

What matters is the X6 started a trend which eventually spawned models like the Mercedes-Benz GLE Coupe and the subject of this comparison, the new Audi Q8.  What also matters is that Porsche will sell a ton of Cayenne Coupe versions.

For you purists, that means more Porsche 911s and 718s. You’ve heard that argument before, but it doesn’t make it any less true. The Porsche Cayenne, Macan, and Panamera ensure that Porsche has more than enough money for every possible 911 variant they can think of and that’s good news for everyone.

The Porsche Cayenne Coupe also arrives at an odd time that will work in its favor. The new BMW X6 (based on the redesigned X5) isn’t quite out yet and a coupe version of the 2020 Mercedes-Benz GLE is still a ways off. If you want to place an order for a four-door luxury mid-size coupe SUV today, the Cayenne Coupe and the Audi Q8 are really your only options.

Both the Porsche Cayenne Coupe and the Audi Q8 share a lot of components like other Porsche and Audi models. When you get to comparing the specs of each four-door SUV, you realize just how similar they are.

2020 Porsche Cayenne Coupe vs Audi Q8 Powertrains

The Porsche Cayenne Coupe is powered by a 3.0-liter turbocharged V6 engine with 335 horsepower and 332 pound-feet of torque. The engine is paired with an 8-speed automatic gearbox and powers the Cayenne Coupe to 100 km/h in 6.0 seconds.

The 2019 Audi Q8 also gets a 3.0-liter turbocharged V6 and an 8-speed gearbox. The Q8 has the same number of horses under the hood (335), but it has quite a bit more torque with 369 pound-feet. Despite having more torque, the Q8 also needs 6.0 seconds to get to 100 km/h.

Base engines may be the same, but the 2020 Cayenne Coupe also offers a Turbo version which ups the ante considerably. Now found under the hood is a 4.0-liter biturbo V8 with 541 horsepower and 568 pound-feet of torque. That gets you to 100 km/h in 3.9 seconds, but it will also cost you a lot more money.

2020 Porsche Cayenne Coupe vs Audi Q8 Price

As you would expect, the Cayenne Coupe is more expensive than the Q8. Pricing in Canada starts at $86,400 for the Cayenne Coupe while the Audi Q8 starts at $81,200. As for the Porsche Cayenne Coupe Turbo, it starts at $148,000.

With anything Porsche, the options need to be taken into account when calculating price. There are a ton of options available in the new Cayenne Coupe, the most noteworthy being the Lightweight Sport Package which adds 22-inch wheels, a carbon roof, a sport design aero kit, heated Alcantara steering wheel, carbon interior package and carbon diffuser. There is plenty of good stuff in there, but the package costs $16,160…

The Audi Q8 isn’t shy about charging extra either. Opt for the top-of-the-line Technik model starting at $88,800 and add every possible option, and you will pay over $100,000.

We are not saying there is no value here because there is. Which model gives you the most value will depend on your own preferences and needs, but regardless the 2020 Porsche Cayenne Coupe will always be more expensive than the Audi Q8.

2020 Porsche Cayenne Coupe vs Audi Q8 Dimensions

The Cayenne Coupe and Q8 share similar dimensions. The Porsche measures 4,931 mm while the Q8 measures 4,999 mm in length. The Q8 is 1,700 in height while the Cayenne Coupe is 1,676 mm. Width is 2,000 mm in the Q8, 2,194 in the Cayenne Coupe.

Essentially, the Porsche Cayenne Coupe is shorter, lower, and wider than the Audi Q8. In the trunk, the Porsche offers 625 liters with all seats in place and 1,540 liters with the rear seats folded. The Audi Q8 gets 605 liters with the rear seats up, and 1,719 liters with the rear seats down.


The Porsche Cayenne Coupe and Audi Q8 are very similar in many respects, but there are slight differences here and there. Of course, we haven’t driven the Cayenne Coupe yet so a more detailed comparison is warranted. For now, the Q8 seems to give you more bang for you buck, but it doesn’t have a Turbo version and it’s not the “latest thing” like the Porsche. That alone puts it at a disadvantage.
