The Stinger has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Impala doesn’t offer a whiplash protection system.

The Stinger offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Impala doesn’t offer all-wheel drive.

The Stinger GT2 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 Stinger GT1/GT2’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 Stinger and the Impala 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes and lane departure warning systems.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Kia Stinger is safer than the Impala:

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, with its optional front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Stinger its highest rating: “Top Pick Plus” for 2019, a rating granted to only 54 vehicles tested by the IIHS. The Impala was not even a standard “Top Pick” for 2016.

The battery on the Stinger is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Stinger’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 rated the Stinger third among compact premium cars in their 2019 Initial Quality Study. The Impala isn’t in the top three in its category.

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.

An eight-speed automatic is standard on the Kia Stinger, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Impala.

The Stinger GT/GT1/GT2’s launch control uses engine electronics to hold engine RPM’s at 2250 in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Impala doesn’t offer launch control.

The Stinger GT-Line’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Impala LT’s standard 50 series tires. The Stinger GT’s 255/35R19 rear tires have a lower 35 series profile than the Impala Premier’s optional 40 series tires.

The Stinger offers an available 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 Stinger’s wheelbase is 2.7 inches longer than on the Impala (114.4 inches vs. 111.7 inches).

For better handling and stability, the average track (width between the wheels) on the Stinger is .6 inches wider in the front and 2.3 inches wider in the rear than the track on the Impala.

The Stinger’s front to rear weight distribution is more even (51.9% to 48.1%) than the Impala’s (59.5% to 40.5%). This gives the Stinger more stable handling and braking.

The Stinger GT2 handles at .93 G’s, while the Impala LT pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The Stinger GT executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the Impala Premier (24.8 seconds @ .79 average G’s vs. 27.1 seconds @ .68 average G’s).

For better maneuverability, the Stinger’s turning circle is 2.1 feet tighter than the Impala’s (36.7 feet vs. 38.8 feet). The Stinger AWD’s turning circle is .4 feet tighter than the Impala’s (38.4 feet vs. 38.8 feet).

The Stinger has a much larger trunk with its rear seat up than the Impala (23.3 vs. 18.8 cubic feet).

A low lift-over trunk design makes loading and unloading the Stinger easier. The Stinger’s trunk lift-over height is 27.5 inches, while the Impala’s liftover is 29.4 inches.

To make loading and unloading groceries and cargo easier when your hands are full, just waiting momentarily behind the back bumper can open the Stinger GT2’s power trunk, leaving your hands completely free. The Stinger’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 Stinger GT2 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 Stinger’s front power windows 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 front passenger window doesn’t close automatically.

The Stinger has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Impala doesn’t offer a locking fuel door.

The Stinger GT1/GT2’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Impala’s manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Stinger’s available headlights were rated “Good” by the IIHS, while the Impala’s headlights are rated “Poor.”

While driving with high beams on, sensitive light sensors standard on the Stinger GT1/GT2 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 Stinger GT2 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Impala doesn’t offer cornering lights.

When the Stinger GT1/GT2 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 Stinger has standard heated front seats. Heated front seats cost extra on the Impala. The Stinger GT2 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Impala.

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