For enhanced safety, the front and rear seat shoulder belts of the Audi A6 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia K900 doesn’t offer pretensioners for the rear seat belts.

Both the A6 and K900 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 K900’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 K900 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.

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 K900 doesn’t offer a night vision system.

Both the A6 and the K900 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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.

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 Pick Plus” for 2020, a rating granted to only 31 vehicles tested by the IIHS. The K900 has not been tested, yet.

The A6 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The K900 doesn’t offer an SMG or a conventional manual transmission.

For better traction, the A6’s optional tires are larger than the largest tires available on the K900 (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 K900’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 K900’s largest wheels are only 19-inches.

The A6 Prestige handles at .93 G’s, while the K900 pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The A6 Prestige executes Motor Trend’s “Figure Eight” maneuver quicker than the K900 (24.9 seconds @ .75 average G’s vs. 25.7 seconds @ .72 average G’s).

For better maneuverability, the A6’s turning circle is 2.8 feet tighter than the K900’s (36.4 feet vs. 39.2 feet).

The Audi A6 may be more efficient, handle and accelerate better because it weighs about 400 to 550 pounds less than the Kia K900.

The A6 is 7.2 inches shorter than the K900, making the A6 easier to handle, maneuver and park in tight spaces.

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 K900’s liftover is 29 inches.

The A6’s standard rear seats fold to accommodate long and bulky cargo. The K900 doesn’t offer folding rear seats, only a ski pass-through.

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 K900 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 K900 can only operate the windows from inside the vehicle, with the ignition on.

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 K900 doesn’t offer headlight washers.

The A6 Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the K900.

Insurance will cost less for the A6 owner. The Complete Car Cost Guide estimates that insurance for the A6 will cost $800 to $2660 less than the K900 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 K900 only retains 27.93%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Audi A6 will be $2178 to $9811 less than for the Kia K900.
