The Cooper Hardtop 2 Door has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RC doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Cooper Hardtop 2 Door offers optional Rear Collision Prevention that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The RC doesn’t offer backup collision prevention brakes.
The Cooper Hardtop 2 Door offers an optional 360-degree camera to allow the driver to see objects all around the vehicle on a screen. The RC 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 Hardtop 2 Door and RC offer rear cross-traffic warning, but the Cooper Hardtop 2 Door with Cross Traffic Warning also has Brake Intervention (automatically applies the brakes) to better prevent a collision when backing near traffic. The RC’s Rear Cross-Traffic Alert doesn’t automatically brake.
Both the Cooper Hardtop 2 Door and the RC 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, daytime running lights, rearview cameras, driver alert monitors, available lane departure warning systems and blind spot warning systems.
