For enhanced safety, the front and rear seat shoulder belts of the Maserati Ghibli 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.
The Ghibli offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The K900 doesn’t offer all-wheel drive.
Both the Ghibli and the K900 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height-adjustable front shoulder belts, traction control and electronic stability systems to prevent skidding.
The Ghibli’s standard 3.0 turbo V6 produces 34 more horsepower (345 vs. 311) and 76 lbs.-ft. more torque (369 vs. 293) than the K900 V6’s standard 3.8 DOHC V6. The Ghibli S’ standard 3.0 turbo V6 produces 30 lbs.-ft. more torque (406 vs. 376) than the K900 V8’s standard 5.0 DOHC V8.
On the EPA test cycle the Ghibli S RWD gets better fuel mileage than the K900 V8 (15 city/25 hwy vs. 15 city/23 hwy).
The Ghibli has 1.3 gallons more fuel capacity than the K900 (21.1 vs. 19.8 gallons), for longer range between fill-ups.
The Ghibli has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The K900 doesn’t offer a cap-less fueling system.
The Ghibli’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.
The Ghibli’s optional 245/35R21 front and 285/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the K900 V8’s 45 series front and 40 series rear tires.
For better ride, handling and brake cooling the Ghibli offers optional 21-inch wheels. The K900’s largest wheels are only 19-inches.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Ghibli can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The K900 doesn’t offer run-flat tires.
The Ghibli offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The K900’s suspension doesn’t offer adjustable shock absorbers.
The Maserati Ghibli may be more efficient, handle and accelerate better because it weighs about 300 to 450 pounds less than the Kia K900.
The Ghibli is 4.9 inches shorter than the K900, making the Ghibli easier to handle, maneuver and park in tight spaces.
The Ghibli has a much larger trunk than the K900 (17.6 vs. 15.9 cubic feet).
The Ghibli’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 Ghibli offers a 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 K900 doesn’t offer a remote starting system.
The Ghibli’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.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Ghibli offers available headlight washers to keep headlight output high. The K900 doesn’t offer headlight washers.
While driving with high beams on, sensitive light sensors available for the Ghibli detect other vehicles which could be blinded and automatically switch to low beams. The K900 doesn’t offer automatic dimming high beams.
