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

The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Collision Mitigation Braking System optional in the Civic Si as “Superior.” The BRZ scores zero, and is rated by the IIHS as having no effective frontal crash prevention.

The Civic Si’s blind spot mirrors use wide-angle convex mirrors mounted in the corner of each side view mirror to reveal objects that may be in the driver’s blind spots. The BRZ doesn’t offer a system to reveal objects in the driver’s blind spots.

The Civic Si has standard HondaLink Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The BRZ doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Civic Si and the BRZ have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 Subaru BRZ:

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 BRZ was not even a “Top Pick” for 2016.

Warranty

There are over 66 percent more Honda dealers than there are Subaru dealers, which makes it much easier should you ever need service under the Civic Si’s warranty.

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Honda vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Honda 23rd in initial quality. With 13 more problems per 100 vehicles, Subaru is ranked 28th.

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 Subaru vehicles. J.D. Power ranks Honda 12th in reliability, above the industry average. With 27 more problems per 100 vehicles, Subaru is ranked 24th.

Engine

The Civic Si’s 1.5 turbo 4 cyl. produces 5 more horsepower (205 vs. 200) and 41 lbs.-ft. more torque (192 vs. 151) than the BRZ’s optional 2.0 DOHC 4 cyl. The Civic Si’s 1.5 turbo 4 cyl. produces 36 lbs.-ft. more torque (192 vs. 156) than the BRZ’s standard 2.0 DOHC 4 cyl.

As tested in Road and Track the Honda Civic Si is faster than the Subaru BRZ (manual transmissions tested):

In a Car and Driver race course test, the Honda Civic Si Coupe was clocked 5.1 seconds faster than the Subaru BRZ Performance Package (194.6 sec. vs. 199.7 sec.).

Fuel Economy and Range

On the EPA test cycle the Civic Si gets better fuel mileage than the BRZ Manual (28 city/38 hwy vs. 21 city/29 hwy).

To lower fuel costs and make buying fuel easier, the Honda Civic Si uses regular unleaded gasoline (premium recommended for maximum performance). The BRZ 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 BRZ doesn’t offer a cap-less fueling system.

Brakes and Stopping

For better stopping power the Civic Si’s standard front brake rotors are larger than those on the BRZ:

Motor Trend

Tires and Wheels

For better traction, the Civic Si has larger tires than the BRZ (235/40R18 vs. 215/45R17).

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 BRZ’s standard 45 series tires. The Civic Si’s optional tires have a lower 35 series profile than the BRZ’s 45 series tires.

For better ride, handling and brake cooling the Civic Si has standard 18-inch wheels. Only 17-inch wheels are available on the BRZ. The Civic Si offers optional 19-inch wheels.

Suspension and Handling

The Civic Si has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The BRZ’s suspension doesn’t offer adjustable shock absorbers.

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 BRZ doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Civic Si’s wheelbase is 5.1 inches longer than on the BRZ (106.3 inches vs. 101.2 inches).

The Civic Si Coupe handles at .97 G’s, while the BRZ Limited pulls only .91 G’s of cornering force in a Car and Driver skidpad test.

Chassis

To almost totally eliminate engine vibration in the passenger area, the Civic Si has a liquid-filled front engine mount. The liquid helps further dampen engine harshness. The BRZ uses conventional solid rubber engine mounts.

As tested by Car and Driver, the interior of the Civic Si Coupe is quieter than the BRZ Limited:

Passenger Space

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

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

The Civic Si Coupe has 12.1 cubic feet more passenger volume than the BRZ (88.6 vs. 76.5).

The Civic Si Coupe has .4 inches more front legroom, 1 inch more front hip room, 2.4 inches more front shoulder room, 6 inches more rear legroom, 2.8 inches more rear hip room and .9 inches more rear shoulder room than the BRZ.

Cargo Capacity

The Civic Si Coupe has a much larger trunk than the BRZ (11.9 vs. 6.9 cubic feet).

The Civic Si’s standard folding rear seats are split to accommodate bulky cargo. The BRZ’s standard single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.

Servicing Ease

The Civic Si has a maintenance free battery for long life without checking the battery’s water level. The BRZ doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

A Smart Maintenance is standard on the Civic Si to save the owner time and money by calculating maintenance intervals for oil changes, spark plug replacement, air filter replacement, tire rotation, radiator flush and transmission fluid replacement based on actual driving conditions. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Subaru doesn’t offer a maintenance reminder on the BRZ.

Ergonomics

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 BRZ can only operate the windows from inside the vehicle, with the ignition on.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Civic Si has standard extendable sun visors. The BRZ doesn’t offer extendable visors.

The Civic Si’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the BRZ Limited.

The Civic Si has a standard center folding armrest for the driver and front passenger. A center armrest helps combat driver fatigue. The BRZ doesn’t offer a front seat center armrest.

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 is only available on the BRZ Limited/Performance Package.

Model Availability

The Honda Civic Si comes in coupe and sedan bodystyles; the Subaru BRZ isn’t available as a sedan.

Recommendations

The Civic Si was chosen as one of Car and Driver’s “Top Ten” in 2018. The BRZ hasn’t been picked since 2013.

The Civic was chosen as one of Automobile Magazine’s “All Stars” for 2 of the last 22 years. The BRZ hasn’t been picked since 2014.

A group of representative automotive journalists from North America selected the Civic as the 2016 North American Car of the Year. The BRZ has never been chosen.

The Honda Civic outsold the Subaru BRZ by almost 93 to one during the 2018 model year.
