The Cayenne offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The A6 Allroad doesn’t offer ceramic brake rotors.

The Cayenne Turbo has standard air brakes, which adjust the spoiler automatically during high-speed braking in order to shorten stopping distances. The A6 Allroad doesn’t offer air brakes.
