The Grand Wagoneer’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 Jeep Grand Wagoneer 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.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Grand Wagoneer are reminded to check the back seat if they opened the rear door before starting out. The DBX doesn’t offer a back seat reminder.
The Grand Wagoneer has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The DBX doesn’t offer a whiplash protection system.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Jeep Grand Wagoneer achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Aston Martin DBX has not been tested.
Over 200 people are killed each year when backed over by motor vehicles. The Grand Wagoneer has standard Park Assist with Rear Stop that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The DBX doesn’t offer automatic braking for stationary objects directly to the rear.
The Grand Wagoneer’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The DBX doesn’t offer a driver alert monitor.
Both the Grand Wagoneer and the DBX 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.
The Jeep Grand Wagoneer weighs 790 to 1235 pounds more than the Aston Martin DBX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
