Over 200 people are killed each year when backed over by motor vehicles. The K900 has standard Rear Cross-Traffic Collision Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A8 doesn’t offer backup collision prevention brakes.

The K900’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A8 doesn’t offer a driver alert monitor.

Both the K900 and the A8 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 and rearview cameras.

The K900 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The A8’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Kia’s powertrain warranty covers the K900 6 years and 50,000 miles longer than Audi covers the A8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the A8 ends after only 4 years or 50,000 miles.

There are almost 3 times as many Kia dealers as there are Audi dealers, which makes it much easier should you ever need service under the K900’s warranty.

The K900 is 7.1 inches shorter than the A8, making the K900 easier to handle, maneuver and park in tight spaces.

The design of the Kia K900 amounts to more than styling. The K900 has an aerodynamic coefficient of drag of .27 Cd. That is lower than the A8 (.27 to .28) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the K900 get better fuel mileage.

The front grille of the K900 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The A8 doesn’t offer active grille shutters.

The K900 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the A8.
