For enhanced safety, the front seat shoulder belts of the Honda Civic Si Sedan 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 Dodge Challenger doesn’t offer height-adjustable seat belts.

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 Challenger’s airbags don’t have smart features and will always deploy full force.

The Civic Si has standard Collision Mitigation Braking System, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Challenger offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.

The Civic Si’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 Challenger doesn’t offer a lane departure warning system.

Both the Civic Si and the Challenger have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Honda Civic Si is safer than the Dodge Challenger:

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 Honda Civic Si Sedan is safer than the Challenger:

The Insurance Institute for Highway Safety (IIHS) performs roof strength tests. In that test the Civic Si earned the top rating of “Good” because its roof supported over four times the Civic Si’s weight before being crushed five inches. The Challenger was rated lower at “Acceptable.”

The Insurance Institute for Highway Safety rates the general design of front seat head restraints for their ability to protect front seat occupants from whiplash injuries. The IIHS also performs a dynamic test on those seats with “good” or “acceptable” geometry. In these ratings, the Civic Si is safer than the Challenger:

For smoother operation, better efficiency and fewer moving parts, the Civic Si has an overhead cam design, rather than the old pushrod design of some of the engines in the Challenger.

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 Si’s reliability 12 points higher than the Challenger.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Honda vehicles are more reliable than Dodge vehicles. J.D. Power ranks Honda 16th in reliability. With 32 more problems per 100 vehicles, Dodge is ranked 28th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Honda vehicles are more reliable than Dodge vehicles. Consumer Reports ranks Honda 6 places higher in reliability than Dodge.

To lower fuel costs and make buying fuel easier, the Honda Civic Si uses regular unleaded gasoline (premium recommended for maximum performance). The Challenger R/T manual requires premium, which can cost 20 to 55 cents more per gallon.

The Civic Si 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 Challenger doesn’t offer a cap-less fueling system.

The Civic Si’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Challenger doesn’t offer drift compensation steering.

The Civic Si Coupe handles at .97 G’s, while the Challenger SXT pulls only .86 G’s of cornering force in a Car and Driver skidpad test.

The Honda Civic Si may be more efficient, handle and accelerate better because it weighs about 950 to 1600 pounds less than the Dodge Challenger.

The Civic Si Coupe is 1 foot, 8.2 inches shorter than the Challenger, making the Civic Si easier to handle, maneuver and park in tight spaces.

The Civic Si is 5.9 inches narrower on average than the Challenger, making the Civic Si easier to handle and maneuver in traffic.

For excellent aerodynamics, the Civic Si has standard flush composite headlights. The Challenger has recessed headlights that spoil its aerodynamic shape and create extra drag.

As tested by Car and Driver, the interior of the Civic Si Coupe is quieter than the Challenger SRT Hellcat:

The Civic Si’s power parking brake sets with one touch and releases with one touch or automatically. The Challenger’s parking brake has to released manually.

The Civic Si’s standard power windows have a locking feature to keep children from operating them. Dodge does not offer a locking feature on the Challenger’s standard power windows.

The Civic Si’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 Challenger’s power windows’ switches have to be held the entire time to close them fully.

If the windows are left open on the Civic Si the driver can close them all at the outside door handle.

The driver of the Challenger can only close the windows from inside the vehicle, with the ignition on.

The Civic Si 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 Challenger doesn’t offer a locking fuel door.
