For enhanced safety, the front seat shoulder belts of the Kia K900 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 8 Series Gran Coupe doesn’t offer height-adjustable seat belts.

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 8 Series Gran Coupe doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the K900. But it costs extra on the 8 Series Gran Coupe.

Both the K900 and the 8 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and driver alert monitors.

Kia’s powertrain warranty covers the K900 6 years and 50,000 miles longer than BMW covers the 8 Series Gran Coupe.
