The Bentayga’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The DBX doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Bentley Bentayga 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 Aston Martin DBX doesn’t offer height-adjustable seat belts.
Both the Bentayga and DBX have child safety locks to prevent children from opening the rear doors. The Bentayga 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 DBX’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 Bentayga has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The DBX doesn’t offer a whiplash protection system.
A passive infrared night vision system optional on the Bentayga 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 projects the image on the windshield, near the driver’s line of sight. The DBX doesn’t offer a night vision system.
The Bentayga has standard Private eCall, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The DBX doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Bentayga and the DBX have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, around view monitors, rear cross-path warning, available collision warning systems and lane departure warning systems.
