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 Toyota Corolla 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 Corolla 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 Corolla doesn’t offer a front passenger side knee airbag.
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 Corolla 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 Corolla 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 Corolla only offers a rear monitor.
The Mazda 3 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Corolla’s blind spot costs extra.
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. Toyota charges extra for Rear Cross-Traffic Alert on the Corolla and the Corolla’s Rear Cross-Traffic Alert does not include automatic braking.
Both the Mazda 3 and the Corolla have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee 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, rearview cameras and driver alert monitors.
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 Toyota Corolla:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mazda 3 Sedan is safer than the Corolla:

The Mazda 3 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Corolla was last only a “Top Safety Pick” in 2023 but no longer qualifies.
