Both the A6 and G90 have child safety locks to prevent children from opening the rear doors. The A6 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The G90’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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 G90 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 A6. But it costs extra on the G90.

A passive infrared night vision system optional on the A6 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The G90 doesn’t offer a night vision system.

Both the A6 and the G90 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

In heavy traffic or at stoplights the A6’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.)

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi A6 higher (5 out of 10) than the Genesis G90 (3 to 5). This means the A6 produces up to 16.5 pounds less smog-producing pollutants than the G90 every 15,000 miles.

For better traction, the A6’s optional tires are larger than the largest tires available on the G90 (255/40R20 vs. 245/45R19).

The A6 Prestige’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the G90’s 45 series front and 40 series rear tires.

For better ride, handling and brake cooling the A6 Prestige offers optional 21-inch wheels. The G90’s largest wheels are only 19-inches.

The A6 Prestige executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the G90 3.3T AWD (24.9 seconds @ .75 average G’s vs. 26.9 seconds @ .67 average G’s).

For better maneuverability, the A6’s turning circle is 2.8 feet tighter than the G90’s (36.4 feet vs. 39.2 feet).

The A6’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 G90 does not have an oil pressure gauge.

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 G90 can only operate the windows from inside the vehicle, with the ignition on.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The A6’s available headlights were rated “Good” by the IIHS, while the G90’s headlights are rated “Acceptable” to .”

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 G90 doesn’t offer headlight washers.

Insurance will cost less for the A6 owner. The Complete Car Cost Guide estimates that insurance for the A6 will cost $1825 to $4440 less than the G90 over a five-year period.

The A6 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the A6 will retain 35.72% to 36.55% of its original price after five years, while the G90 only retains 32.66% to 33.07%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi A6 will be $13086 to $13298 less than for the Genesis G90.
