For enhanced safety, the front and rear seat shoulder belts of the Subaru Solterra have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Ford Mustang Mach-E doesn’t offer pretensioners for its rear seat belts.
The Subaru Solterra 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 Mustang Mach-E doesn’t offer a front passenger side knee airbag.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Solterra. But it costs extra on the Mustang Mach-E.
When descending a steep, off-road slope, the Solterra’s standard Downhill Assist Control allows you to creep down safely. The Mustang Mach-E doesn’t offer Downhill Assist Control.
Both the Solterra and the Mustang Mach-E 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
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 Subaru Solterra is safer than the Mustang Mach-E:

The Subaru Solterra 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 Mustang Mach-E is not even a standard “Top Safety Pick” for 2024.
