The MINI Cooper Hardtop 4 Door has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Impreza doesn’t offer a front passenger side knee airbag.
The Cooper Hardtop 4 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 Impreza 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 4 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 Impreza doesn’t offer backup collision prevention brakes.
The Cooper Hardtop 4 Door offers an optional 360-degree camera to allow the driver to see objects all around the vehicle on a screen. The Impreza only offers a rear monitor.
Both the Cooper Hardtop 4 Door and Impreza offer rear cross-traffic warning, but the Cooper Hardtop 4 Door with Cross Traffic Warning also has Brake Intervention (automatically applies the brakes) to better prevent a collision when backing near traffic. The Impreza’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Cooper Hardtop 4 Door and the Impreza have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver 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, available lane departure warning systems and blind spot warning systems.
