For enhanced safety, the front and rear seat shoulder belts of the Subaru WRX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Audi S3 doesn’t offer pretensioners for its rear seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the WRX are reminded to check the back seat if they opened the rear door before starting out. The S3 doesn’t offer a back seat reminder.
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 S3 doesn’t offer a whiplash protection system.
With its standard Pre-Collision System with Pedestrian Detection, the Subaru WRX is better at preventing collisions with pedestrians than the Audi S3, according to the Insurance Institute for Highway Safety:

Over 200 people are killed each year when backed over by motor vehicles. The WRX Limited SPT/GT has standard Reverse Automatic Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The S3 doesn’t offer automatic braking for stationary objects directly to the rear.
The WRX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The S3 doesn’t offer a driver alert monitor.
Both the WRX and the S3 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.
The Subaru WRX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The S3 is not a “Top Safety Pick” for 2024.
