For enhanced safety, the front and rear seat shoulder belts of the Mazda 3 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 Clubman doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Mazda 3 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 Clubman doesn’t offer height-adjustable seat belts.
The Mazda 3 has standard Whiplash Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Cooper Clubman doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The Mazda 3 Turbo Premium Plus has standard Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Cooper Clubman doesn’t offer backup collision prevention brakes.
The Mazda 3 Turbo Premium Plus has a standard 360-Degree Monitor to allow the driver to see objects all around the vehicle on a screen. The Cooper Clubman 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.
The Mazda 3 Select/Preferred/Carbon/Premium/Turbo’s 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 Clubman 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 Mazda 3 Select/Preferred/Carbon/Premium/Turbo’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross Traffic Braking on the Turbo Premium Plus automatically engages the brakes to help avoid a collision. The Cooper Clubman doesn’t offer a rear cross-path warning system.
Both the Mazda 3 and the Cooper Clubman have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available all wheel drive.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Mazda 3 the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The Cooper Clubman has not been tested, yet.
