For enhanced safety, the front and rear seat shoulder belts of the Aston Martin DBX 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 Audi SQ5 Sportback doesn’t offer pretensioners for its rear seat belts.
The Aston Martin DBX 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 SQ5 Sportback doesn’t offer knee airbags.
Both the DBX and the SQ5 Sportback have standard driver and passenger frontal airbags, front 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
The Aston Martin DBX weighs 608 pounds more than the Audi SQ5 Sportback. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
