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.

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.

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 has not yet been evaluated by the IIHS for 2024.

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