“When the car comes to a stop, and when accelerating out of a stop there is a significant problem with engine on/off mechanism. The final stop is exceptionally rough and the acceleration mechanism takes a moment to engage. This should not be the case with a luxury car like Porsche and is a real problem for me.”
2021 Porsche Cayenne: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2021 Porsche Cayenne is the return of the GTS, a lower and sportier model powered by a twin-turbo V8. Otherwise, this is a light-update year rather than a redesign.
About the 2021 Porsche Cayenne
3rd generation Cayenne (2019-2023), third model year before the major 2024 update; 2021 adds the GTS back into the range.
Porsche positions the Cayenne as the SUV for people who still care deeply about how a vehicle drives. It is meant to blend sports-car responses with everyday family use, towing ability, all-weather traction, and a premium cabin. What separates it from many luxury SUVs is Porsche’s emphasis on steering feel, chassis tuning, and strong turbocharged powertrains, whether the buyer chooses the base model, a plug-in hybrid, or one of the V8 performance versions.
The core Cayenne has a 335-hp turbocharged V6, all-wheel drive, and a 12.3-inch touchscreen, while the S provides stronger twin-turbo V6 performance. The returning GTS is the louder, lower V8 model below the Turbo, and the 670-hp Turbo S E-Hybrid tops the range with plug-in power and more advanced handling hardware.
What changed, by category
Powertrain
The GTS returns with a 453-hp twin-turbo 4.0-liter V8. The E-Hybrid and Turbo S E-Hybrid receive a larger 17.9-kWh battery, improving electric driving range compared with 2020.
Styling
The returning GTS has its own sport-focused exterior treatment, dark trim, and tinted lighting. The broader Cayenne range does not receive a visual refresh.
Chassis
The GTS adds a three-chamber air suspension with adaptive dampers and a ride height lowered by 30 mm for a more performance-focused feel.
