The GLE Coupe’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 Mercedes GLE Coupe 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 GLE Coupe 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 GLE Coupe offers optional Post-Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The DBX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The GLE Coupe has a standard Maneuvering Assistant 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.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLE Coupe has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The DBX doesn’t offer a system that can receive automated systems from other vehicles.
The GLE Coupe’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.
The GLE Coupe has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, 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 GLE Coupe and the DBX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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 and available lane departure warning systems.
