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 Escape PHEV doesn’t offer pre-crash pretensioners.
Both the iX and Escape PHEV 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 Escape PHEV’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 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Escape PHEV doesn’t offer a front passenger side knee airbag.
The iX’s standard pretensioning seatbelts also sense rear collisions and remove slack from the front seatbelts to help protect the occupants from whiplash and other injuries. The Escape PHEV doesn’t offer a whiplash protection system.
The iX offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Escape PHEV doesn’t offer all-wheel drive.
The iX offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Escape PHEV 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.
Both the iX and the Escape PHEV have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 and driver alert monitors.
The BMW iX weighs 1789 to 1899 pounds more than the Ford Escape PHEV. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
