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. A system to reveal vehicles in the 8 Series’ blind spot costs extra.
To help make backing out of a parking space safer, the Z has standard Rear Cross Traffic Alert, helping the driver avoid collisions. BMW charges extra for Cross Traffic Warning on the 8 Series.
Both the Z and the 8 Series 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.
