As tested in Car and Driver the Porsche Cayenne turbo V6 is faster than the Audi A6 Allroad:

On the EPA test cycle the Cayenne running on electricity gets better mileage than the A6 Allroad:

The Cayenne can travel with zero emissions for 15 to 17 miles (dependent on model). The A6 Allroad can’t move without running its internal combustion engine.

The Cayenne’s standard fuel tank has 4.4 gallons more fuel capacity than the A6 Allroad (23.7 vs. 19.3 gallons).

An eight-speed automatic is standard on the Porsche Cayenne, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A6 Allroad.

For better stopping power the Cayenne CCB’s brake rotors are larger than those on the A6 Allroad:

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.

The Cayenne stops much shorter than the A6 Allroad:

For better traction, the Cayenne has larger standard tires than the A6 Allroad (F:255/55R19 & R:275/50R19 vs. 245/45R20). The Cayenne’s optional tires are larger than the largest tires available on the A6 Allroad (F:285/40R21 & R:315/35R21 vs. 245/45R20).

The Cayenne’s optional 285/35R22 front and 315/30R22 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the A6 Allroad’s 45 series tires.

For better ride, handling and brake cooling the Cayenne offers optional 22-inch wheels. The A6 Allroad’s largest wheels are only 20-inches.

The Cayenne offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The A6 Allroad doesn’t offer an active sway bar system.

The Cayenne offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Audi doesn’t offer an active suspension on the A6 Allroad.

For better handling and stability, the average track (width between the wheels) on the Cayenne is 1.5 inches wider in the front and 2.4 inches wider in the rear than the track on the A6 Allroad.

The Cayenne handles at .96 G’s, while the A6 Allroad Prestige pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The Cayenne Turbo executes Motor Trend’s “Figure Eight” maneuver 2.6 seconds quicker than the A6 Allroad Prestige (23.9 seconds @ .83 average G’s vs. 26.5 seconds @ .68 average G’s).

For better maneuverability, the Cayenne w/Rear Wheel Steering’s turning circle is 4.9 feet tighter than the A6 Allroad’s (35.1 feet vs. 40 feet). The Cayenne’s turning circle is .2 feet tighter than the A6 Allroad’s (39.8 feet vs. 40 feet).

For greater off-road capability the Cayenne has a 2.1 inches greater minimum ground clearance than the A6 Allroad Premium Plus (8.2 vs. 6.1 inches), allowing the Cayenne to travel over rougher terrain without being stopped or damaged. The Cayenne Air Suspension’s minimum ground clearance is 2.3 inches higher than on the A6 Allroad Prestige (9.6 vs. 7.3 inches).

The front grille of the Cayenne uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The A6 Allroad doesn’t offer active grille shutters.

The Cayenne has .7 inches more front headroom, 1.3 inches more front shoulder room and 2.9 inches more rear legroom than the A6 Allroad.

Standard trailer sway control on the Cayenne uses the Porsche Stability Management sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The A6 Allroad doesn’t offer electronic trailer sway control.

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Audi. J.D. Power ranks Porsche third in service department satisfaction. With a 14% lower rating, Audi is ranked 8th.

The Cayenne’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The A6 Allroad has neither an oil pressure gauge nor a temperature gauge.
