For enhanced safety, the front and rear seat shoulder belts of the Genesis Electrified G80 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 Electrified G80 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.
The Electrified G80 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Mustang Mach-E doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Electrified G80. But it costs extra on the Mustang Mach-E.
Both the Electrified G80 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.
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 Genesis Electrified G80 is safer than the Mustang Mach-E:
