The RS 3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The WRX doesn’t offer pre-crash pretensioners.

For enhanced safety, the front and rear seat shoulder belts of the Audi RS 3 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 Subaru WRX has only front height-adjustable seat belts.

The RS 3 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The WRX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the RS 3 and the WRX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and rear cross-path warning.

The RS 3’s corrosion warranty is 7 years longer than the WRX’s (12 vs. 5 years).

A hardened steel chain, with no maintenance needs, drives the camshafts in the RS 3’s engine. A rubber cam drive belt that needs periodic replacement drives the WRX’s camshafts. If the WRX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

To reliably power the ignition and other systems and to recharge the battery, the RS 3 has a standard 150-amp alternator. The WRX’s standard 130-amp alternator and largest (STI) 110-amp alternator aren’t as powerful.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Audi vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks Audi 22nd in initial quality. With 7 more problems per 100 vehicles, Subaru is ranked 25th.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Subaru vehicles. J.D. Power ranks Audi 8th in reliability, above the industry average. With 12 more problems per 100 vehicles, Subaru is ranked 14th.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Audi RS 3 higher (3 out of 10) than the Subaru WRX (1). This means the RS 3 produces up to 22.5 pounds less smog-producing pollutants than the WRX every 15,000 miles.

The Audi RS 3 comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the WRX.

The RS 3 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The WRX doesn’t offer an SMG.

The RS 3’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The WRX doesn’t offer launch control.

The RS 3’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the WRX are solid, not vented.

The RS 3 offers optional heat-treated ceramic front brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The WRX doesn’t offer ceramic brake rotors.

For better traction, the RS 3’s optional front tires are larger than the largest tires available on the WRX (255/30R19 vs. 245/40R18).

The RS 3’s standard tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the WRX’s standard 45 series tires. The RS 3’s optional 255/30R19 front tires have a lower 30 series profile than the WRX STI’s 35 series tires.

For better ride, handling and brake cooling the RS 3 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the WRX.

The RS 3 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 WRX’s suspension doesn’t offer adjustable shock absorbers.

For better handling and stability, the track (width between the wheels) on the RS 3 is 1.2 inches wider in the front than on the WRX.

The RS 3 handles at .98 G’s, while the WRX STI Limited pulls only .90 G’s of cornering force in a Car and Driver skidpad test.

The RS 3’s power parking brake sets with one touch and releases with one touch or automatically. The WRX has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The power windows standard on both the RS 3 and the WRX have locks to prevent small children from operating them. When the lock on the RS 3 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The WRX prevents the driver from operating the other windows just as it does the other passengers.

The RS 3’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The WRX’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the RS 3 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the WRX can only operate the windows from inside the vehicle, with the ignition on.

The RS 3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The WRX’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the RS 3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The WRX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RS 3 has standard headlight washers to keep headlight output high. The WRX doesn’t offer headlight washers.

The RS 3 has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The WRX has an automatic headlight on/off feature standard only on the Premium/STI/Limited.

The RS 3 has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The WRX offers an automatic rear view mirror, but its side mirrors don’t dim.

The RS 3 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 WRX STI.

Both the RS 3 and the WRX offer rear vents. For greater rear passenger comfort, the RS 3 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The WRX doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi RS 3 has a standard wireless phone charging system (Qi) in the center console. The WRX doesn’t offer wireless personal charging.
