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 TLX 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 TLX.

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 TLX doesn’t offer a driver alert monitor.

Both the K900 and the TLX have standard driver and passenger frontal airbags, front 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, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.

The Kia K900 weighs 824 to 1157 pounds more than the Acura TLX. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

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 TLX’s 4-year/50,000-mile basic warranty expires 1 year and 10,000 miles sooner.

Kia’s powertrain warranty covers the K900 4 years and 30,000 miles longer than Acura covers the TLX. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the TLX ends after only 6 years or 70,000 miles.

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

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 TLX’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 Acura vehicles. J.D. Power ranks Kia second in initial quality, above the industry average. With 40 more problems per 100 vehicles, Acura is ranked 24th, below the industry average.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Kia vehicles are more reliable than Acura vehicles. J.D. Power ranks Kia 10th in reliability, above the industry average. With 45 more problems per 100 vehicles, Acura is ranked 26th.

From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Kia vehicles are more reliable than Acura vehicles. Consumer Reports ranks Kia 19 places higher in reliability than Acura.

For better traction, the K900 has larger tires than the TLX (F:245/45R19 & R:275/40R19 vs. 225/55R17).

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 TLX’s standard 55 series tires.

For better ride, handling and brake cooling the K900 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the TLX.

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 TLX’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the K900’s wheelbase is 12.9 inches longer than on the TLX (122.2 inches vs. 109.3 inches).

For better handling and stability, the track (width between the wheels) on the K900 is 1.7 inches wider in the front and 1.4 inches wider in the rear than on the TLX.

The K900 handles at .87 G’s, while the TLX V6 SH-AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The K900 executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the TLX (25.7 seconds @ .72 average G’s vs. 27 seconds @ .74 average G’s).

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 TLX doesn’t offer active grille shutters.

Because it has more passenger and cargo room, the EPA rates the K900 a Large car, while the TLX is rated a Compact.

The K900 has 16.7 cubic feet more passenger volume than the TLX (110 vs. 93.3).

The K900 has 3.9 inches more front headroom, 3.1 inches more front legroom, 1.5 inches more front shoulder room, 1.3 inches more rear headroom, 2.1 inches more rear legroom and 1.8 inches more rear shoulder room than the TLX.

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

The K900 has a larger trunk than the TLX (15 vs. 14.3 cubic feet).

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 TLX 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 TLX. 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 in the TLX, 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 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 TLX doesn’t offer a heads-up display.

The power windows standard on both the K900 and the TLX have locks to prevent small children from operating them. When the lock on the K900 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The TLX prevents the driver from operating the other windows just as it does the other passengers.

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 TLX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 TLX 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 TLX doesn’t offer a rear sunshade.

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 TLX 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 is only available on the TLX Advance.

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. Wireless charging costs extra on the TLX.
