For enhanced safety, the front and rear seat shoulder belts of the Hyundai Ioniq 5 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.
When descending a steep, off-road slope, the Ioniq 5’s standard Downhill Brake Control allows you to creep down safely. The Mustang Mach-E doesn’t offer Downhill Brake Control.
Both the Ioniq 5 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.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Ioniq 5 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 50 vehicles tested by the IIHS. The Mustang Mach-E was last a “Top Safety Pick Plus” in 2019 but no longer qualifies.
