Compare the2023 Audi A6VS 2023 Porsche Panamera

The A6’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 A6 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.

Over 200 people are killed each year when backed over by motor vehicles. The A6 Prestige has standard backup collision prevention system that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Panamera doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A6. But it costs extra on the Panamera.

To help make backing out of a parking space safer, the A6’s optional Rear Cross-Traffic Assist uses sensors in the rear to alert the driver to vehicles approaching from the side and Automatic Brake Activation automatically engages the brakes to help avoid a collision. The Panamera doesn’t offer a rear cross-path warning system.

Both the A6 and the Panamera have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Panamera has not been tested, yet.

There are over 56 percent more Audi dealers than there are Porsche dealers, which makes it much easier should you ever need service under the A6’s warranty.

On the EPA test cycle the A6 gets better mileage than the Panamera Sedan running its gasoline engine:

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A6 higher (5 out of 10) than the Porsche Panamera (3 to 5). This means the A6 produces up to 16.5 pounds less smog-producing pollutants than the Panamera every 15,000 miles.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The A6 has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Panamera doesn’t offer a brake assist feature.

The A6 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.

The A6 is 4.4 inches shorter than the Panamera, making the A6 easier to handle, maneuver and park in tight spaces.

The design of the Audi A6 amounts to more than styling. The A6 has an aerodynamic coefficient of drag of .29 Cd. That is lower than the Panamera (.29 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A6 get better fuel mileage.

The A6 has 3 cubic feet more passenger volume than the Panamera (99 vs. 96).

The A6 has .1 inches more rear headroom, 1.8 inches more rear legroom and 2.2 inches more rear shoulder room than the Panamera.

A low lift-over trunk design makes loading and unloading the A6 easier. The A6’s trunk lift-over height is 27 inches, while the Panamera’s liftover is 29.7 inches.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the A6 offers cargo security. The Panamera’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

The A6 has a 3500 lbs. towing capacity. The Panamera has no towing capacity.

The A6’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Panamera.

If the windows are left open on the A6 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Panamera can only operate the windows from inside the vehicle, with the ignition on.

The A6’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Panamera’s cruise control switches are unlit, making them difficult to find at night and operate safely.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A6 Premium Plus/Prestige has standard headlight washers to keep headlight output high. The Panamera doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A6 has standard extendable sun visors. The Panamera doesn’t offer extendable visors.

The A6 Prestige’s Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Park Assist Plus will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Panamera doesn’t offer an automated parking system.

Insurance will cost less for the A6 owner. The Complete Car Cost Guide estimates that insurance for the A6 will cost $1930 to $12115 less than the Panamera over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi A6 will be $29759 to $97142 less than for the Porsche Panamera.
