For enhanced safety, the front and second-row seat shoulder belts of the Audi Q7 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 BMW X7 doesn’t offer pretensioners for its second-row seat belts.
For enhanced safety, the front seat shoulder belts of the Audi Q7 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 BMW X7 doesn’t offer height-adjustable front seat belts.
Both the Q7 and X7 have child safety locks to prevent children from opening the rear doors. The Q7 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 X7’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.
A passive infrared night vision system optional on the Q7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The X7 doesn’t offer a night vision system.
Both the Q7 and the X7 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, 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 and available around view monitors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Q7 the rating of “Top Safety Pick” for 2017, a rating granted to only 220 vehicles tested by the IIHS. The X7 has not been tested, yet.
