The Audi S6 doesn’t offer pretensioners for the rear seat belts.

Both the Panamera and the S6 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Fuel Economy and Range Comparison

On the EPA test cycle the Panamera S E-Hybrid running its gasoline engine gets better fuel mileage than the S6 (23 city/29 hwy vs. 17 city/27 hwy).

The Panamera S E-Hybrid can drive on battery power alone for up to 22 miles. The S6 must run its internal combustion engine to move.

Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it. The S6 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Panamera’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The S6 doesn’t offer an automatic engine start/stop system.

The Panamera Hybrid/V6/S RWD’s standard fuel tank has 1.3 gallons more fuel capacity than the S6 (21.1 vs. 19.8 gallons), for longer range between fill-ups. The Panamera S4/GTS/Turbo’s standard fuel tank has 6.6 gallons more fuel capacity than the S6 (26.4 vs. 19.8 gallons).

Brakes and Stopping Comparison

For better stopping power the Panamera Turbo/GTS’ front brake rotors are larger than those on the S6:

15.7 inches

The Panamera 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 S6 doesn’t offer ceramic brake rotors.

The Panamera stops shorter than the S6:

Car and Driver

Tires and Wheels Comparison

For better traction and acceleration, the Panamera has larger standard rear tires than the S6 (275/45R18 vs. 255/40R19). The Panamera’s optional rear tires are larger than the largest rear tires available on the S6 (295/35R20 vs. 255/40R19).

Suspension and Handling Comparison

The Panamera 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 S6.

For a smoother ride and more stable handling, the Panamera’s wheelbase is .3 inches longer than on the S6 (115 inches vs. 114.7 inches). The Panamera Executive’s wheelbase is 6.2 inches longer than on the S6 (120.9 feet vs. 114.7 inches).

For better handling and stability, the average track (width between the wheels) on the Panamera is 1.6 inches wider in the front and 2.1 inches wider in the rear than the track on the S6.

The Panamera’s front to rear weight distribution is more even (52% to 48%) than the S6’s (57% to 43%). This gives the Panamera more stable handling and braking.

The Panamera Turbo 4 handles at .97 G’s, while the S6 pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs up to about 500 pounds less than the Audi S6.

As tested by Car and Driver while at idle, the interior of the Panamera Turbo 4 is quieter than the S6 (43 vs. 44 dB).

Passenger Space Comparison

The Panamera has .8 inches more front headroom, .6 inches more front legroom and .4 inches more rear headroom than the S6.

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The S6’s rear seats don’t recline.

Cargo Capacity Comparison

To make loading and unloading groceries and cargo easier, especially for short adults or children, the Panamera has a standard power rear liftgate, which opens and closes automatically by pressing a button. The S6 doesn’t offer a power trunk.

Ergonomics Comparison

The Panamera offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The S6 doesn’t offer a remote starting system.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The S6 doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Panamera has standard headlight washers to keep headlight output high. The S6 doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the Panamera detect other vehicles which could be blinded and automatically switch to low beams. The S6 doesn’t offer automatic dimming high beams.

To help keep rear passengers entertained, the Panamera offers optional rear seat controls for the radio which can play a separate audio source. The S6 doesn’t offer rear seat audio controls.

The Panamera offers an optional 115 volt a/c outlet in the center console, allowing you to recharge a laptop or run small household appliances without special adapters which can break or get misplaced. The S6 doesn’t offer a house-current electrical outlet.

Economic Advantages Comparison

The Panamera will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the Panamera will retain 45.33% to 51.12% of its original price after five years, while the S6 only retains 42.8%.

Recommendations Comparison

The Porsche Panamera won the Check it Out award in Kiplinger’s 2013 car issue. The Audi S6 didn't win any award.
