The WRX has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Civic Si doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The WRX Limited SPT/GT has standard Reverse Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Civic Si doesn’t offer backup collision prevention brakes.

The WRX Premium/Limited/GT has standard STARLINK Connected Services, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Civic Si doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the WRX and the Civic Si have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Subaru vehicles are more reliable than Honda With 4 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Subaru higher than Honda.

The WRX’s 2.4 turbo 4-cylinder produces 71 more horsepower (271 vs. 200) and 66 lbs.-ft. more torque (258 vs. 192) than the Civic Si’s 1.5 turbo 4-cylinder.

As tested in Consumer Reports the Subaru WRX is faster than the Honda Civic Si (manual transmissions tested):

The flat cylinder configuration of the boxer engine in the WRX lowers its center of gravity, enhancing handling stability (That’s why Porsche uses boxer engines.). The Civic Si doesn’t offer a boxer engine configuration.

The WRX has 4.2 gallons more fuel capacity than the Civic Si (16.6 vs. 12.4 gallons), for longer range between fill-ups.

The WRX offers an optional automatic transmission, for driver comfort, especially in the city. The Civic Si doesn’t offer an automatic transmission.

The WRX offers an optional continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Civic Si doesn’t offer a CVT.

The WRX’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Civic Si are solid, not vented.

The WRX stops much shorter than the Civic Si:

For better traction, the WRX’s optional tires are larger than the largest tires available on the Civic Si (245/40R18 vs. 235/40R18).

The WRX has standard front and rear gas-charged shocks for better control over choppy roads. The Civic Si’s suspension doesn’t offer gas-charged shocks.

The WRX offers an available 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 Civic Si’s suspension doesn’t offer adjustable shock absorbers.

The WRX Limited handles at .96 G’s, while the Civic Si pulls only .93 G’s of cornering force in a Motor Trend skidpad test.

The WRX Limited executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the Civic Si (24.8 seconds @ .75 average G’s vs. 26.3 seconds @ .67 average G’s).

The WRX has 2.2 inches more front headroom, .8 inches more front legroom and .4 inches more rear hip room than the Civic Si.

To allow full utilization of available cargo room, the WRX’s trunk lid uses concealed beam hinges that don’t intrude into the trunk. The Civic Si’s useful trunk space is reduced by its intrusive beam hinge.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the WRX. The Civic Si doesn’t offer locking storage for small valuables.

The WRX uses gas struts to support the hood for easier service access. The Civic Si uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

The engine in the WRX is mounted longitudinally (North-South), instead of sideways, as in the Civic Si. This makes it easier to service and maintain, because the accessory belts are in front.

The WRX offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house.

To help drivers see further while navigating curves, the WRX Premium/Limited/GT has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Civic Si doesn’t offer cornering lights.

The WRX’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Civic Si doesn’t offer the luxury of automatic dimming mirrors.

The WRX Premium/Limited/GT has standard heated front seats, which keep the driver and front passenger extremely comfortable in the winter. Heated seats aren’t available in the Civic Si.

The WRX Premium/Limited/GT’s 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. The Civic Si doesn’t offer dual zone air conditioning.

To direct the driver from any location to a given street address, a GPS navigation system is standard on the WRX Limited/GT. The WRX’s navigation system also has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service not available in all areas.)
