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 SE Countryman 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 SE Countryman 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 SE Countryman doesn’t offer height-adjustable seat belts.
Both the ID.4 and SE Countryman 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 SE Countryman’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 Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Autonomous Emergency Braking in the ID.4 as “Superior.” The SE Countryman scores only 3 points and is rated only “Advanced.”
Over 200 people are killed each year when backed over by motor vehicles. The ID.4 has standard Maneuver Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The SE Countryman doesn’t offer backup collision prevention brakes.
The ID.4 Pro S Plus has a standard Area View to allow the driver to see objects all around the vehicle on a screen. The SE Countryman 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 ID.4’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 and moves the vehicle back into its lane. The SE Countryman 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 ID.4’s standard Rear Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The SE Countryman doesn’t offer a rear cross-path warning system.
Both the ID.4 and the SE Countryman 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, rearview cameras and driver alert monitors.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the ID.4 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 67 vehicles tested by the IIHS. The SE Countryman last would have qualified as only a standard “Top Safety Pick” in 2017.
