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 ES Series doesn’t offer pre-crash pretensioners.

The K900 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ES Series doesn’t offer all-wheel drive.

Both the K900 and the ES Series 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.

The Kia K900 weighs 958 to 1013 pounds more than the Lexus ES Series. 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 ES Series’ 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 Lexus covers the ES Series. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the ES Series ends after only 6 years or 70,000 miles.

There are over 3 times as many Kia dealers as there are Lexus 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 ES Series’ 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 Lexus vehicles. J.D. Power ranks Kia second in initial quality, above the industry average. With 20 more problems per 100 vehicles, Lexus is ranked 8th.

For better traction, the K900 has larger tires than the ES Series (F:245/45R19 & R:275/40R19 vs. 215/55R17). The K900’s tires are larger than the largest tires available on the ES Series (F:245/45R19 & R:275/40R19 vs. 235/45R18).

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 ES Series’ 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 ES Series.

For a smoother ride and more stable handling, the K900’s wheelbase is 9.2 inches longer than on the ES Series (122.2 inches vs. 113 inches).

For better handling and stability, the track (width between the wheels) on the K900 is 1.8 inches wider in the front and 1.4 inches wider in the rear than the average track on the ES Series.

The K900 handles at .87 G’s, while the ES 300h pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The K900 executes Motor Trend’s “Figure Eight” maneuver 2.7 seconds quicker than the ES 300h (25.7 seconds @ .72 average G’s vs. 28.4 seconds @ .6 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 ES Series doesn’t offer active grille shutters.

Because it has more passenger and cargo room, the EPA rates the K900 a Large car, while the ES Series is rated a Mid-size.

The K900 has 10.1 cubic feet more passenger volume than the ES Series (110 vs. 99.9).

The K900 has 3.6 inches more front headroom, 3.3 inches more front legroom, 3.1 inches more front shoulder room, .2 inches more rear headroom and 2.9 inches more rear shoulder room than the ES Series.

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

To allow full utilization of available cargo room, the K900’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The ES Series’ useful trunk space is reduced by its intrusive beam hinge.

The engine in the K900 is mounted longitudinally (North-South), instead of sideways, as in the ES Series. 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 ES Series, 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 ES Series.

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 ES Series’ standard manually variable intermittent wipers have to be constantly adjusted.

The K900 has standard heated front seats. Heated front seats cost extra on the ES Series. 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 ES Series.

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 ES Series 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 ES Series.

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 ES Series.
