For enhanced safety, the front and rear seat shoulder belts of the Acura ZDX 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 Countryman SE doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Acura ZDX 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 Countryman SE doesn’t offer height-adjustable seat belts.
Both the ZDX and Countryman SE have child safety locks to prevent children from opening the rear doors. The ZDX has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Countryman SE’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Acura ZDX achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The MINI Countryman SE has not been tested.
Both the ZDX and the Countryman SE 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
The Acura ZDX weighs 833 to 1464 pounds more than the MINI Countryman SE. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
