Safety

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

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

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Civic Si the rating of “Top Pick” for 2017, a rating granted to only 139 vehicles tested by the IIHS. The Mustang has not been tested, yet.

Reliability

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 14 points higher than the Mustang.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Honda vehicles are more reliable than Ford vehicles. J.D. Power ranks Honda 12th in reliability, above the industry average. With 12 more problems per 100 vehicles, Ford is ranked 16th.

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

Car and Driver

Tires and Wheels

The Civic Si’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Mustang’s standard 55 series tires.

For better ride, handling and brake cooling the Civic Si has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Mustang.

Suspension and Handling

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 Mustang doesn’t offer drift compensation steering.

The Civic Si Coupe handles at .97 G’s, while the Mustang GT Premium Fastback pulls only .96 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The Honda Civic Si may be more efficient, handle and accelerate better because it weighs about 650 to 1000 pounds less than the Ford Mustang.

The Civic Si Coupe is 11.1 inches shorter than the Mustang, making the Civic Si easier to handle, maneuver and park in tight spaces.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the Civic Si Coupe a Compact car, while the Mustang Fastback is rated a Subcompact.

The Civic Si has standard seating for 5 passengers; the Mustang can only carry 4.

The Civic Si Coupe has 5.8 cubic feet more passenger volume than the Mustang Fastback (88.6 vs. 82.8).

The Civic Si Coupe has .6 inches more front shoulder room, 6.9 inches more rear legroom, .7 inches more rear hip room and .4 inches more rear shoulder room than the Mustang Fastback.

Ergonomics

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

If the windows are left open on the Civic Si the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Mustang 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 Mustang doesn’t offer a locking fuel door.

The Civic Si’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Ford only offers heated mirrors on the Mustang Premium.

The Civic Si has a 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. Dual zone air conditioning costs extra on the Mustang.

Economic Advantages

Insurance will cost less for the Civic Si owner. The Complete Car Cost Guide estimates that insurance for the Civic Si will cost $575 less than the Mustang over a five-year period.

The Civic Si will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Civic Si will retain 52.64% to 54.77% of its original price after five years, while the Mustang only retains 41.02% to 57.01%.

According to The Car Book by Jack Gillis, the Civic Si is less expensive to operate than the Mustang because it costs $180 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Civic Si than the Mustang, including $596 less for a muffler, $58 less for front brake pads, $15 less for fuel injection, $255 less for a timing belt/chain and $754 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Honda Civic Si will be $4504 to $25224 less than for the Ford Mustang.
