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 Rolls-Royce Ghost doesn’t offer height-adjustable seat belts.
The K900 has standard Forward Collision Avoidance, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Ghost offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
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 Ghost doesn’t offer backup collision prevention brakes.
The K900 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Ghost doesn’t offer all-wheel drive.
The K900’s blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. The Ghost doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing safer, the K900’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Ghost doesn’t offer a cross-path warning system.
Both the K900 and the Ghost 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, daytime running lights, rearview cameras and driver alert monitors.
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 Ghost’s 4-year basic warranty expires 1 year sooner.
Kia’s powertrain warranty covers the K900 6 years longer than Rolls-Royce covers the Ghost. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Ghost ends after only 4 years.
The K900’s corrosion warranty is 1 year longer than the Ghost’s (5 vs. 4 years).
There are almost 22 times as many Kia dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the K900’s warranty.
In heavy traffic or at stoplights the K900’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.) The Ghost doesn’t offer an automatic engine start/stop system.
For better traction and acceleration, the K900 has larger rear tires than the Ghost (275/40R19 vs. 255/50R19).
The K900’s 245/45R19 front and 275/40R19 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Ghost’s standard 50 series tires.
The K900 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Ghost, it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.
The K900 handles at .87 G’s, while the Ghost pulls only .84 G’s of cornering force in a Motor Trend skidpad test.
The K900 executes Motor Trend’s “Figure Eight” maneuver quicker than the Ghost (25.7 seconds @ .72 average G’s vs. 26.3 seconds @ .72 average G’s).
For better maneuverability, the K900’s turning circle is 4.8 feet tighter than the Ghost’s (39.2 feet vs. 44 feet). The K900’s turning circle is 6.7 feet tighter than the Ghost Extended Wheelbase’s (39.2 feet vs. 45.9 feet).
The Kia K900 may be more efficient, handle and accelerate better because it weighs about 700 to 1000 pounds less than the Rolls-Royce Ghost.
The K900 is 1 foot, 1.2 inches shorter than the Ghost, 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 significantly lower than the Ghost (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the K900 get better fuel mileage.
For excellent aerodynamics, the K900 has standard flush composite headlights. The Ghost has recessed headlights that spoil its aerodynamic shape and create extra drag.
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 Ghost doesn’t offer active grille shutters.
The K900 has .5 inches more front headroom, 4 inches more front legroom and 1.4 inches more rear shoulder room than the Ghost.
The K900 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Ghost doesn’t offer a remote starting system.
The K900’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Ghost’s rear power window switches have to be held the entire time to close them fully.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the K900 has standard extendable sun visors. The Ghost doesn’t offer extendable visors.
On extremely cold winter days, the K900’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Ghost doesn’t offer a heated steering wheel.
