For enhanced safety, the front and rear seat shoulder belts of the Mazda CX-50 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 Subaru Crosstrek doesn’t offer pretensioners for its rear seat belts.
The Mazda CX-50 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 Crosstrek doesn’t offer a front passenger side knee airbag.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Mazda CX-50 achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Subaru Crosstrek has not been tested.
The CX-50 has standard Secondary Collision Reduction System, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Crosstrek 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.
The CX-50 Turbo Premium Plus has a standard 360° Monitor to allow the driver to see objects all around the vehicle on a screen. The Crosstrek only offers a rear monitor.
The CX-50 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 Crosstrek’s blind spot costs extra.
To help make backing out of a parking space safer, the CX-50 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. Subaru charges extra for Rear Cross Traffic Alert on the Crosstrek and its not available on the Base and the Crosstrek’s Rear Cross Traffic Alert does not include automatic braking.
Both the CX-50 and the Crosstrek 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 and driver alert monitors.
The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the CX-50 is much safer than the Crosstrek:

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 CX-50 is safer than the Crosstrek:

The Mazda CX-50 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 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 Crosstrek is not even a standard “Top Safety Pick” for 2025.
