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 Civic Si 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 Civic Si 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 Civic Si only offers a rear monitor.

The Stinger has standard 911 Connect, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The Civic Si doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Stinger and the Civic Si 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, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.

The Kia Stinger weighs 908 to 1270 pounds more than the Honda Civic Si. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.

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, its standard vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Stinger its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 80 vehicles tested by the IIHS. The Civic Si has not been tested, yet.

Warranty

The Stinger comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Civic Si’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the Stinger 5 years and 40,000 miles longer than Honda covers the Civic Si. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Civic Si ends after only 5 years or 60,000 miles.

Reliability

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 Civic Si’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2021 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Honda vehicles. J.D. Power ranks Kia above average in initial quality. With 17 more problems per 100 vehicles, Honda is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Kia vehicles are more reliable than Honda vehicles. J.D. Power ranks Kia first in reliability, above the industry average. With 85 more problems per 100 vehicles, Honda is ranked 24th.

Engine

The Stinger GT-Line’s standard 2.5 turbo 4-cylinder produces 100 more horsepower (300 vs. 200) and 119 lbs.-ft. more torque (311 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder. The Stinger GT2’s standard 3.3 turbo V6 produces 168 more horsepower (368 vs. 200) and 184 lbs.-ft. more torque (376 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder.

Fuel Economy and Range

In heavy traffic or at stoplights the Stinger’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. The Civic Si doesn’t offer an automatic engine start/stop system.

The Stinger has 3.5 gallons more fuel capacity than the Civic Si (15.9 vs. 12.4 gallons), for longer range between fill-ups.

Transmission

The Stinger has a standard automatic transmission, for driver comfort, especially in the city. The Civic Si doesn’t offer an automatic transmission.

The Stinger 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 Civic Si doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Stinger’s brake rotors are larger than those on the Civic Si:

	Stinger GT-Line	Stinger GT2	Civic Si
Front Rotors	13.6 inches	13.8 inches	12.3 inches
Rear Rotors	13 inches	13.4 inches	11.1 inches

The Stinger GT2’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Civic Si are solid, not vented.

The Stinger stops shorter than the Civic Si:

	Stinger	Civic Si
70 to 0 MPH	156 feet	160 feet	Car and Driver
60 to 0 MPH	104 feet	110 feet	Motor Trend

Tires and Wheels

The Stinger GT2’s 255/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Civic Si’s 40 series tires.

For better ride, handling and brake cooling the Stinger GT2 has standard 19-inch wheels. The Civic Si’s largest wheels are only 18-inches.

The Stinger has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Civic Si; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The Stinger has standard front and rear gas-charged shocks for better control over choppy roads. The Civic Si’s suspension doesn’t offer gas-charged shocks.

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 Civic Si’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Stinger’s wheelbase is 6.7 inches longer than on the Civic Si (114.4 inches vs. 107.7 inches).

For better handling and stability, the average track (width between the wheels) on the Stinger is 2.3 inches wider in the front and 2.5 inches wider in the rear than the track on the Civic Si.

The Stinger’s front to rear weight distribution is more even (51.9% to 48.1%) than the Civic Si’s (60.3% to 39.7%). This gives the Stinger more stable handling and braking.

The Stinger executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the Civic Si (24.8 seconds @ .79 average G’s vs. 26.3 seconds @ .67 average G’s).

For better maneuverability, the Stinger’s turning circle is 1.4 feet tighter than the Civic Si’s (36.7 feet vs. 38.1 feet).

Passenger Space

The Stinger has .7 inches more front headroom, .3 inches more front legroom, 1.2 inches more front hip room and 7.2 inches more rear hip room than the Civic Si.

Cargo Capacity

To allow full utilization of available cargo room, the Stinger’s hatch uses gas strut supported hinges that don’t intrude into the cargo area. The Civic Si’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 Stinger. The Civic Si doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier when your hands are full, the Stinger GT2’s power liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Stinger’s power liftgate can also be opened or closed by pressing a button. The Civic Si doesn’t offer a power or hands-free opening trunk.

Servicing Ease

The Stinger uses gas struts to support the hood for easier service access. The Civic Si uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the Stinger is mounted longitudinally (North-South), instead of sideways, as in the Civic Si. This makes it easier to service and maintain, because the accessory belts are in front.

Ergonomics

The Stinger has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Civic Si doesn’t offer a remote starting system.

When two different drivers share the Stinger GT2, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position (with optional power wheel adjuster) and outside mirror angle. The Civic Si doesn’t offer a memory system.

The Stinger GT2’s standard easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Civic Si doesn’t offer an easy entry system.

The Stinger GT2 has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Civic Si doesn’t offer a heads-up display.

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

The Stinger’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Civic Si’s passenger power window switches are unlit, making them difficult to find at night and operate safely.

The Stinger’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 Civic Si’s 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 Stinger GT2 has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Civic Si doesn’t offer cornering lights.

When the Stinger 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 Civic Si’s mirrors don’t automatically adjust for backing.

The Stinger’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Civic Si doesn’t offer the luxury of automatic dimming mirrors.

The Stinger has standard heated front and second row seats (second row heated seats on GT2) extremely comfortable in the winter. Heated seats aren’t available in the Civic Si.

Standard air-conditioned seats in the Stinger GT2 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Civic Si doesn’t offer air-conditioned seats.

On extremely cold winter days, the Stinger’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Civic Si doesn’t offer a heated steering wheel.

The Stinger’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Civic Si doesn’t offer dual zone air conditioning.

Both the Stinger and the Civic Si offer rear vents. For greater rear passenger comfort, the Stinger has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Civic Si doesn’t offer rear air conditioning vents, only heat vents.

To direct the driver from any location to a given street address, a GPS navigation system is standard on the Stinger. The Stinger’s navigation system also has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Civic Si doesn’t offer a navigation system.

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. The Civic Si doesn’t offer wireless personal charging.
