For enhanced safety, the front and rear seat shoulder belts of the Subaru Impreza have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The MINI Cooper Hardtop 4 Door doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Subaru Impreza are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The MINI Cooper Hardtop 4 Door doesn’t offer height-adjustable seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Impreza are reminded to check the back seat if they opened the rear door before starting out. The Cooper Hardtop 4 Door doesn’t offer a back seat reminder.
The Impreza has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Cooper Hardtop 4 Door doesn’t offer a whiplash protection system.
The Impreza has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Cooper Hardtop 4 Door doesn’t offer all-wheel drive.
The Impreza (except Base)’s optional blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Cooper Hardtop 4 Door doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the Impreza (except Base)’s optional Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Cooper Hardtop 4 Door doesn’t offer a rear cross-path warning system.
Both the Impreza and the Cooper Hardtop 4 Door have standard driver and passenger frontal airbags, front 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, lane departure warning systems and rearview cameras.
