Compare the2025 Honda CivicVS 2025 Kia K4

The Honda Civic has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The K4 doesn’t offer knee airbags.

Using vehicle speed sensors and seat sensors, smart airbags in the Civic deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Civic’s side airbags will shut off if a child is leaning against the door. The K4’s side airbags don’t have smart features and will always deploy full force.

The Civic’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The K4 doesn’t offer a lane departure warning system.

Both the Civic and the K4 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available blind spot warning systems, rear parking sensors and rear cross-path warning.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Honda Civic Sedan is safer than the K4:

The Honda Civic has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The K4 is only a standard “Top Safety Pick” for 2024, though it hasn’t yet been rated in the updated moderate overlap frontal test, a requirement for the “Top Safety Pick Plus” award.

The Civic’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the K4 runs out after 100,000 miles.

There are over 35 percent more Honda dealers than there are Kia dealers, which makes it easier should you ever need service under the Civic’s warranty.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Civic’s reliability 12 points higher than the K4.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Honda vehicles are more reliable than Kia vehicles. Consumer Reports ranks Honda fourth in overall reliability. Kia is ranked 9th.

The Civic’s standard 2.0 DOHC 4-cylinder produces 3 more horsepower (150 vs. 147) and 1 lbs.-ft. more torque (133 vs. 132) than the K4’s standard 2.0 DOHC 4-cylinder. The Civic Hybrid’s standard 2.0 DOHC 4-cylinder hybrid produces 10 more horsepower (200 vs. 190) and 37 lbs.-ft. more torque (232 vs. 195) than the K4 GT-Line Turbo’s standard 1.6 turbo 4-cylinder.

As tested in Car and Driver the Civic Hybrid 2.0 DOHC 4-cylinder hybrid is faster than the K4 GT-Line Turbo 1.6 turbo 4-cylinder:

On the EPA test cycle the Civic Sedan gets better mileage than the K4:

On the EPA test cycle the Civic Hatchback gets better mileage than the K4:

Regenerative brakes improve the Civic Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The K4 doesn’t offer a regenerative braking system.

The Civic has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The K4 doesn’t offer a cap-less fueling system.

The Civic stops shorter than the K4:

For better traction, the Civic has larger standard tires than the K4 (215/55R16 vs. 205/55R16).

For superior ride and handling, the Honda Civic has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The K4 has a rear torsion beam axle, with a semi-independent rear suspension.

The Civic has standard front and rear stabilizer bars, which help keep the Civic flat and controlled during cornering. The K4 base model’s suspension doesn’t offer a rear stabilizer bar.

The Civic Sport Sedan handles at .87 G’s, while the K4 GT-Line Turbo pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The Civic Sedan is 6.4 inches shorter than the K4, making the Civic easier to handle, maneuver and park in tight spaces.

The Civic Hybrid uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The K4 doesn’t offer active noise cancellation.

The Civic has .3 inches more front headroom, 1 inch more front hip room, .5 inches more front shoulder room and 1.3 inches more rear shoulder room than the K4.

The Civic’s front power windows open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The K4’s standard passenger windows don’t open or close automatically. The K4 EX/GT-Line’s rear windows don’t close automatically.

The Civic Sport Hybrid’s standard wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers and the Civic Sport Hybrid Touring’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The K4’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 Civic’s headlights were rated “Good” by the IIHS, while the K4’s headlights are rated “Acceptable.”

The Honda Civic comes in sedan and four door hatchback bodystyles; the Kia K4 isn’t available as a four door hatchback.
