The Z 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 GR86 doesn’t offer a whiplash protection system.
The Z has standard Front and Rear Sonar System to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The GR86 doesn’t offer a front parking aid.
The Z has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the GR86 Premium/Yuzu Edition offers a blind spot warning system.
To help make backing out of a parking space safer, the Z has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Only the GR86 Premium/Yuzu Edition offers Rear Cross Traffic Alert.
Both the Z and the GR86 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
The Nissan Z weighs 618 to 893 pounds more than the Toyota GR86. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
