The Cooper Convertible offers an optional 360-degree camera to allow the driver to see objects all around the vehicle on a screen. The Z4 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Cooper Convertible and Z4 offer Cross Traffic Warning, but the Cooper Convertible with Cross Traffic Warning also has Brake Intervention (automatically applies the brakes) to better prevent a collision when backing near traffic. The Z4’s Cross Traffic Warning doesn’t automatically brake.
Both the Cooper Convertible and the Z4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, driver alert monitors, available lane departure warning systems and blind spot warning systems.
