For enhanced safety, the front and second-row seat shoulder belts of the Hyundai Ioniq 9 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.

The Ioniq 9 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Mustang Mach-E doesn’t offer front seat center airbags.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Hyundai Ioniq 9 achieved a “Good” rating - the 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.

When descending a steep, off-road slope, the Ioniq 9’s standard Downhill Brake Control allows you to creep down safely. The Mustang Mach-E doesn’t offer Downhill Brake Control.

The Hyundai Ioniq 9 comes with a standard Surround View Monitor, while the Ford Mustang Mach-E doesn’t offer a camera washer, requiring manual cleaning.

Both the Ioniq 9 and the Mustang Mach-E have standard driver and passenger frontal airbags, front and rear 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, 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 Hyundai Ioniq 9 weighs 532 to 1614 pounds more than the Ford Mustang Mach-E. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

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 Hyundai Ioniq 9 is safer than the Mustang Mach-E:

	Ioniq 9	Mustang Mach-E

Structure	GOOD	ACCEPTABLE
	Driver Injury Measures

The Hyundai Ioniq 9 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2026 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, a “Good” score in the revised pedestrian crash prevention test, and a “Good” score in the revised vehicle-to-vehicle crash prevention test. The Mustang Mach-E is only a standard “Top Safety Pick” for 2026.

For a smoother ride and more stable handling, the Ioniq 9’s wheelbase is 5.7 inches longer than on the Mustang Mach-E Select/Premium (123.2 inches vs. 117.5 inches).

For better handling and stability, the average track (width between the wheels) on the Ioniq 9 is 3.3 inches wider in the front and 3.9 inches wider in the rear than the track on the Mustang Mach-E.

The Ioniq 9 Calligraphy handles at .88 G’s, while the Mustang Mach-E 4 pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The Ioniq 9 Calligraphy Design executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the Mustang Mach-E (26.2 seconds @ .72 average G’s vs. 28 seconds @ .62 average G’s).

For greater off-road capability the Ioniq 9 has a 1.1 inches greater minimum ground clearance than the Mustang Mach-E (6.9 vs. 5.8 inches), allowing the Ioniq 9 to travel over rougher terrain without being stopped or damaged.

The Ioniq 9 Calligraphy has a standard heads-up display that projects speed, navigation instruction and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road.
