For enhanced safety, the front shoulder belts of the Chevrolet Impala are height-adjustable, and the rear seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Kia K900 has only front height-adjustable seat belts.

Both the Impala and K900 have child safety locks to prevent children from opening the rear doors. The Impala has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The K900’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Both the Impala and the K900 have standard driver and passenger frontal airbags, front and rear side-impact 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, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

For its top level performance in the IIHS moderate overlap frontal impact, side impact, rear impact, roof-crush crash tests, an “Acceptable” rating in the newer small overlap frontal crash test, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Impala its highest rating: “Top Pick Plus” for 2015, a rating granted to only 154 vehicles tested by the IIHS. The K900 has not been tested, yet.


The Impala’s corrosion warranty is 1 year longer than the K900’s (6/100,000 vs. 5/100,000).

There are almost 4 times as many Chevrolet dealers as there are Kia dealers, which makes it much easier should you ever need service under the Impala’s warranty.


The Impala has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The K900 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

Fuel Economy and Range

On the EPA test cycle the Impala V6 gets better fuel mileage than the K900 V6 (19 city/28 hwy vs. 17 city/25 hwy).

In heavy traffic or at stoplights the Impala 4 cyl.’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 K900 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Chevrolet Impala uses regular unleaded gasoline. The K900 with the 5.0 DOHC V8 engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Brakes and Stopping

The Impala stops shorter than the K900:





60 to 0 MPH

115 feet

123 feet

Motor Trend

Tires and Wheels

The Impala Premier’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the K900 V8 Luxury’s 45 series front tires.

For better ride, handling and brake cooling the Impala Premier offers optional 20-inch wheels. The K900’s largest wheels are only 19-inches.

Suspension and Handling

The Impala’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The K900 doesn’t offer drift compensation steering.

The Impala Premier handles at .83 G’s, while the K900 V8 Luxury pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The Impala LT executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the K900 V8 Luxury (26.7 seconds @ .67 average G’s vs. 28.3 seconds @ .61 average G’s).


The Chevrolet Impala may be more efficient, handle and accelerate better because it weighs about 550 to 800 pounds less than the Kia K900.

The Impala 4 cyl. uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The K900 doesn’t offer active noise cancellation.

Cargo Capacity

The Impala has a much larger trunk than the K900 (18.8 vs. 15.9 cubic feet).

The Impala’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 Impala has a 1000 lbs. towing capacity. The K900 has no towing capacity.


The Impala offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The K900 doesn’t offer a house-current electrical outlet.


Consumer Reports® chose the Chevrolet Impala as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance.

The Chevrolet Impala outsold the Kia K900 by almost 167 to one during 2017.
