The 2021 Audi Q8 and 2021 Porsche Cayenne compete as compelling luxury SUVs. Although, the Porsche Cayenne adds a performance pedigree to the mix. To learn more about how these vehicles compare, keep reading below.


The Porsche Cayenne’s power comes from a 335 horsepower 3.0-liter turbocharged V6 engine paired with an 8-speed shiftable automatic. Other available powertrains include a turbocharged 2.9-liter six-cylinder engine that’s good for 434 horsepower, a turbocharged 4.0-liter V8 engine that’s good for 453 horsepower, and another 4.0-liter turbocharged V8 engine that pumps out 541 horsepower. All-wheel drive is standard for the Cayenne. There are even two hybrid models, which include the Cayenne E-Hybrid with 455 horsepower and the Cayenne Turbo S E-Hybrid with 670 horsepower.

Meanwhile, the 2021 Audi Q8 only offers one engine, which is a 3.0 liter turbocharged V6 that produces 335 horsepower and is paired with an 8-speed automatic transmission with standard all-wheel drive.

Even with the comparable base engine, the Cayenne achieves a higher top speed of 152 mph compared to the Q8’s top speed of 130 mph. Additionally, the Cayenne offers a lighter weight, which allows for faster acceleration and better handling. Combine this with all of the different engine options available, and the Cayenne wins over the Audi Q8 when it comes to performance.


The interior of the Audi Q8 may not be as luxurious and spacious as the Porsche Cayenne. However, it is still extremely refined, with lots of technology options to upgrade your ride. Unfortunately, the Audi Q8 suffers from a cumbersome dual touchscreen setup. The Porsche Cayenne’s interior is also very stylish and comes with an easy-to-use 12.4-inch touchscreen display that includes navigation and wireless Apple CarPlay.
