Compare the2025 Honda Civic SiVS 2024 Mercedes AMG CLA

For enhanced safety, the front seat shoulder belts of the Honda Civic Si are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes AMG CLA doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Civic Si are reminded to check the back seat if they opened the rear door before starting out. The AMG CLA doesn’t offer a back seat reminder.

Using vehicle speed sensors and seat sensors, smart airbags in the Civic Si 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 Si’s side airbags will shut off if a child is leaning against the door. The AMG CLA’s side airbags don’t have smart features and will always deploy full force.

The Civic Si’s standard 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. A lane departure warning system costs extra on the AMG CLA.

Both the Civic Si and the AMG CLA have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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.
