The iX’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Trailseeker doesn’t offer pre-crash pretensioners.
Both the iX and Trailseeker have child safety locks to prevent children from opening the rear doors. The iX 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 Trailseeker’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 BMW iX’s optional Surround View is available with washers for its front and rear cameras, ensuring crystal-clear visibility in any weather condition. Conversely, the Subaru Trailseeker only offers a rear camera washer, which may not provide the same level of all-weather performance.
Both the iX and the Trailseeker have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all-wheel drive, 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.
The BMW iX weighs 1002 to 1384 pounds more than the Subaru Trailseeker. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
