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 Civic Type R doesn’t offer a back seat reminder.
The Mazda 3 has standard Whiplash Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Civic Type R doesn’t offer a whiplash protection system.
With its standard Smart Brake Support, the Mazda 3 is better at preventing collisions with pedestrians than the Honda Civic Type R, according to the Insurance Institute for Highway Safety:

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 Civic Type R 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 Civic Type R 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 Civic Type R only offers a rear monitor.
Both the Mazda 3 and Civic Type R have rear cross-traffic warning, but the Mazda 3 Turbo Premium Plus has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Civic Type R’s Cross Traffic Monitor doesn’t automatically brake.
The Mazda 3 has standard E911 Automatic Emergency Notification, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The Civic Type R doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Mazda 3 and the Civic Type R have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning 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 Honda Civic Type R:
