For enhanced safety, the front and rear seat shoulder belts of the Volkswagen ID.4 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.
The ID.4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Countryman SE doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Volkswagen ID.4 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 ID.4 and Countryman SE have child safety locks to prevent children from opening the rear doors. The ID.4 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.
The Volkswagen ID.4’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the MINI Countryman SE does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the ID.4 and the Countryman SE have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
