For enhanced safety, the front and rear seat shoulder belts of the Mazda 3 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 Acura ILX 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 Mazda 3 are reminded to check the back seat if they opened the rear door before starting out. The ILX doesn’t offer a back seat reminder.
The Mazda 3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The ILX doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Mazda 3 Turbo Premium Plus has standard Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The ILX doesn’t offer backup collision prevention brakes.
The Mazda 3 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ILX doesn’t offer all-wheel drive.
The Mazda 3 Turbo Premium Plus has a standard 360-Degree Monitor to allow the driver to see objects all around the vehicle on a screen. The ILX only offers a rear monitor.
To help make backing out of a parking space safer, the Mazda 3 has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking on the Turbo Premium Plus automatically engages the brakes to help avoid a collision. Acura charges extra for Rear Cross Traffic Monitor on the ILX and the ILX’s Rear Cross Traffic Monitor does not include automatic braking.
The Mazda 3’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 ILX doesn’t offer a driver alert monitor.
Both the Mazda 3 and the ILX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems 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 Mazda 3 is safer than the Acura ILX:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Mazda 3 the rating of “Top Safety Pick” for 2023, a rating granted to only 54 vehicles tested by the IIHS. The ILX last would have qualified as a “Top Safety Pick” in 2017.
