The Challenger has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Q60 doesn’t offer a whiplash protection system.
Compared to metal, the Challenger’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Infiniti Q60 has a metal gas tank.
Both the Challenger and the Q60 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, collision warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.
