Safety

The A8 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 A8 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 A8 and the K900 have standard driver and passenger frontal 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, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The A8’s corrosion warranty is 7 years and unlimited miles longer than the K900’s (12/unlimited vs. 5/100,000).

Fuel Economy and Range

On the EPA test cycle the A8 V6T gets better fuel mileage than the K900 (19 city/27 hwy vs. 18 city/25 hwy).

Regenerative brakes improve the A8’s fuel efficiency by converting inertia back into energy instead of wasting it. The K900 doesn’t offer a regenerative braking system.

Brakes and Stopping

For better stopping power the A8’s brake rotors are larger than those on the K900:

 

A8

K900

Front Rotors

14.8 inches

14.2 inches

Rear Rotors

13.8 inches

13.4 inches

The A8’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the K900 are solid, not vented.

Tires and Wheels

For better traction, the A8 has larger tires than the K900 (255/45R19 vs. 245/45R19).

For better ride, handling and brake cooling the A8 offers optional 20-inch wheels. The K900’s largest wheels are only 19-inches.

Suspension and Handling

The front and rear suspension of the A8 uses air springs for a smoother, controlled ride than the K900, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The A8 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Kia doesn’t offer an active suspension on the K900.

The A8 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The A8’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The K900 doesn’t offer a load leveling suspension.

Passenger Space

The A8 has .1 inches more front shoulder room, .5 inches more rear headroom, 7.7 inches more rear legroom and .4 inches more rear shoulder room than the K900.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Audi service is better than Kia. J.D. Power ranks Audi third in service department satisfaction. With a 45% lower rating, Kia is ranked 18th.

Ergonomics

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A8 has standard headlight washers to keep headlight output high. The K900 doesn’t offer headlight washers.

Recommendations

The Audi A8/S8 outsold the Kia K900 by almost four to one during the 2018 model year.
