The K900’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Impala doesn’t offer pre-crash pretensioners.

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 Impala 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 Impala doesn’t offer all-wheel drive.

The K900 has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Impala only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

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 Impala doesn’t offer a driver alert monitor.

Both the K900 and the Impala 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, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

The Kia K900 weighs 862 to 932 pounds more than the Chevrolet Impala. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The battery on the K900 is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the K900’s battery 20 to 30 degrees cooler, its life is increased by years. The Impala’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Chevrolet vehicles. J.D. Power ranks Kia second in initial quality, above the industry average. With 15 more problems per 100 vehicles, Chevrolet is ranked 6th.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Kia vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Kia 16 places higher in reliability than Chevrolet.

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 Impala doesn’t offer an automatic engine start/stop system.

The K900 has 1.8 gallons more fuel capacity than the Impala (20.3 vs. 18.5 gallons), for longer range between fill-ups.

For better traction, the K900 has larger tires than the Impala (F:245/45R19 & R:275/40R19 vs. 235/50R18).

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 Impala LT’s standard 50 series tires.

For better ride, handling and brake cooling the K900 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Impala LT.

The K900 has a standard 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 Impala’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the K900’s wheelbase is 10.5 inches longer than on the Impala (122.2 inches vs. 111.7 inches).

For better handling and stability, the track (width between the wheels) on the K900 is 2.3 inches wider in the front and 2.5 inches wider in the rear than on the Impala.

The K900 handles at .87 G’s, while the Impala Premier pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The K900 executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Impala Premier (25.7 seconds @ .72 average G’s vs. 27.1 seconds @ .68 average G’s).

The K900 has 5 cubic feet more passenger volume than the Impala (110 vs. 105).

The K900 has 1.2 inches more front headroom, 1.1 inches more front shoulder room, .6 inches more rear headroom and .3 inches more rear shoulder room than the Impala.

For enhanced passenger comfort on long trips the K900’s available rear seats recline. The Impala’s rear seats don’t recline.

With its sedan body style, valet key and remote trunk release lockout, the K900 offers cargo security. The Impala’s non-lockable folding seat and non-lockable remote release defeat cargo security.

To make loading and unloading groceries and cargo easier when your hands are full, the K900’s power trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The K900’s power trunk can also be opened or closed by pressing a button. The Impala doesn’t offer a power or hands-free opening trunk.

The engine in the K900 is mounted longitudinally (North-South), instead of sideways, as in the Impala. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Unlike the driver-only memory system optional at extra cost in the Impala Premier, the K900 has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The K900’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Impala, and is not available on all models.

The K900 has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Impala doesn’t offer a heads-up display.

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 Impala’s passenger windows don’t close automatically.

The K900’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Impala’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors standard on the K900 detect other vehicles which could be blinded and automatically switch to low beams. The Impala doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the K900 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Impala doesn’t offer cornering lights.

A power rear sunshade and manual rear side window sunshades are standard in the K900 to help block heat and glare for the rear passengers. The Impala doesn’t offer a rear sunshade.

When the K900 is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Impala’s mirrors don’t automatically adjust for backing.

The K900 has standard heated front seats. Heated front seats cost extra on the Impala. The K900 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Impala.

The K900 has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Impala doesn’t offer air-conditioned seats in the rear.

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 Impala.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Kia K900 has a standard wireless phone charging system (Qi) in the center console and one for the rear passengers. Only the Impala Premier offers wireless charging and it costs extra.
