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 LaCrosse 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 LaCrosse 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 LaCrosse.

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

Both the K900 and the LaCrosse 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 822 to 1172 pounds more than the Buick LaCrosse. 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 LaCrosse’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 Buick covers the LaCrosse. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the LaCrosse ends after only 6 years or 70,000 miles.

The K900’s 3.3 turbo V6 produces 171 more horsepower (365 vs. 194) and 189 lbs.-ft. more torque (376 vs. 187) than the LaCrosse’s standard 2.5 DOHC 4-cylinder hybrid. The K900’s 3.3 turbo V6 produces 55 more horsepower (365 vs. 310) and 108 lbs.-ft. more torque (376 vs. 268) than the LaCrosse’s optional 3.6 DOHC V6.

For better traction, the K900 has larger tires than the LaCrosse (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 LaCrosse’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 LaCrosse.

For a smoother ride and more stable handling, the K900’s wheelbase is 7.8 inches longer than on the LaCrosse (122.2 inches vs. 114.4 inches).

For better handling and stability, the track (width between the wheels) on the K900 is 1.6 inches wider in the front and 1.4 inches wider in the rear than on the LaCrosse.

The K900 handles at .87 G’s, while the LaCrosse Premium pulls only .84 G’s of cornering force in a Motor Trend skidpad test.

The K900 executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the LaCrosse Premium (25.7 seconds @ .72 average G’s vs. 26.8 seconds @ .66 average G’s).

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

The K900 has 8 cubic feet more passenger volume than the LaCrosse (110 vs. 102).

The K900 has 2.7 inches more front headroom, 3.7 inches more front legroom, 1.3 inches more front shoulder room, .8 inches more rear headroom and .6 inches more rear shoulder room than the LaCrosse.

For enhanced passenger comfort on long trips the K900’s available rear seats recline. The LaCrosse’s 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 LaCrosse’s useful trunk space is reduced by its intrusive beam hinge.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the K900. The LaCrosse doesn’t offer locking storage for small valuables.

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 LaCrosse 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 LaCrosse. 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 LaCrosse Sport Touring/Essence/Premium/Avenir, 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 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 LaCrosse’s rear power window switches have to be held the entire time to close them fully.

The Smart Key standard on the K900 allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Buick LaCrosse’s Keyless Access doesn’t unlock the trunk.

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 LaCrosse’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 LaCrosse doesn’t offer automatic dimming high beams.

The K900 has standard heated front seats. Heated front seats are only available on the LaCrosse Sport Touring/Essence/Premium/Avenir. 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 LaCrosse.

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 LaCrosse 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 LaCrosse Premium/Avenir.
