For enhanced safety, the front and rear seat shoulder belts of the Hyundai Tucson Plug-In Hybrid 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 Ford Mustang Mach-E doesn’t offer pretensioners for its rear seat belts.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Hyundai Tucson Plug-In Hybrid 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 Ford Mustang Mach-E has not been tested.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Tucson Plug-In Hybrid. But it costs extra on the Mustang Mach-E.
When descending a steep, off-road slope, the Tucson Plug-In Hybrid’s standard Downhill Brake Control allows you to creep down safely. The Mustang Mach-E doesn’t offer Downhill Brake Control.
Both the Tucson Plug-In Hybrid and the Mustang Mach-E have standard driver and passenger frontal airbags, front and rear side-impact 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, 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.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Hyundai Tucson Plug-In Hybrid is safer than the Ford Mustang Mach-E:
