Safety Comparison

The S6’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Panamera doesn’t offer pre-crash pretensioners.

The S6 has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Panamera doesn’t offer a whiplash protection system.

The S6 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Panamera doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the S6. But it costs extra on the Panamera.

An active infrared night vision system optional on the S6 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight. The Panamera doesn’t offer a night vision system.

To help make backing safer, the S6’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Panamera doesn’t offer a cross-path warning system.

Both the S6 and the Panamera have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, front and rear parking sensors, available crash mitigating brakes, lane departure warning systems and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the S6 its highest rating: “Top Pick Plus” for 2016, a rating granted to only 84 vehicles tested by the IIHS. The Panamera has not been tested, yet.

Warranty Comparison

There are over 30 percent more Audi dealers than there are Porsche dealers, which makes it easier should you ever need service under the S6’s warranty.

Reliability Comparison

To reliably power the ignition and other systems and to recharge the battery, the S6 has a standard 210-amp alternator. The Panamera’s 190-amp alternator isn’t as powerful.

Engine Comparison

The S6’s 4.0 turbo V8 produces 140 more horsepower (450 vs. 310) and 111 lbs.-ft. more torque (406 vs. 295) than the Panamera’s standard 3.6 DOHC V6. The S6’s 4.0 turbo V8 produces 34 more horsepower (450 vs. 416) than the Panamera S E-Hybrid’s standard 3.0 supercharged V6 hybrid. The S6’s 4.0 turbo V8 produces 30 more horsepower (450 vs. 420) and 22 lbs.-ft. more torque (406 vs. 384) than the Panamera S’ standard 3.0 turbo V6.

3.8 sec

5.5 sec

Quarter Mile

12.4 sec

14.1 sec

Fuel Economy and Range Comparison

On the EPA test cycle the S6 gets better fuel mileage than the Panamera Turbo (18 city/27 hwy vs. 15 city/24 hwy). The S6 gets better fuel mileage than the Panamera GTS (18 city/27 hwy vs. 16 city/24 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the S6’s fuel efficiency. The Panamera doesn’t offer a system that can shut down part of the engine.

Brakes and Stopping Comparison

For better stopping power the S6’s standard brake rotors are larger than those on the Panamera:



Front Rotors

15.7 inches

14.2 inches

Rear Rotors

14 inches

13 inches

Tires and Wheels Comparison

For better traction, the S6 has larger tires than the Panamera (255/40R19 vs. 245/50R18).

The S6’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Panamera’s standard 50 series front and 45 series rear tires. The S6’s optional tires have a lower 35 series profile than the Panamera’s optional 40 series front tires.

For better ride, handling and brake cooling the S6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Panamera.

The S6 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Panamera, it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling Comparison

The front and rear suspension of the S6 uses air springs for a smoother, controlled ride than the Panamera, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

Chassis Comparison

The S6 is 3 inches shorter than the Panamera, making the S6 easier to handle, maneuver and park in tight spaces. The S6 is 9 inches shorter than the Panamera Executive.

The design of the Audi S6 amounts to more than styling. The S6 has an aerodynamic coefficient of drag of .29 Cd. That is lower than the Panamera (.29 to .32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the S6 get better fuel mileage.

The S6 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Panamera doesn’t offer active noise cancellation.

As tested by Car and Driver while at idle, the interior of the S6 is quieter than the Panamera Turbo 4 (40 vs. 44 dB).

Passenger Space Comparison

The S6 has standard seating for 5 passengers; the Panamera can only carry 4.

The S6 has 5.6 inches more front shoulder room, 4.2 inches more rear legroom and 4.6 inches more rear shoulder room than the Panamera.

Cargo Capacity Comparison

With its sedan body style, locking rear seatbacks and remote trunk release lockout, the S6 offers cargo security. The Panamera’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

To make loading groceries and cargo easier when your hands are full, the S6’s trunk can be opened just by holding your hand near the emblem on the trunk, leaving your hands completely free. The Panamera doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

The S6 offers an optional heads-up display which projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Panamera doesn’t offer a heads-up display.

Recommendations Comparison

The S6 was chosen as one of Car and Driver’s “Top Ten” for 5 of the last 17 years. The Panamera has never been a Car and Driver “Top Ten” pick.

The Audi A6/S6 outsold the Porsche Panamera by almost five to one during 2015.
