For enhanced safety, the front and second-row seat shoulder belts of the Infiniti QX80 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 Dodge Durango doesn’t offer pretensioners for its second-row 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 QX80 are reminded to check the back seat if they opened the rear door before starting out. The Durango doesn’t offer a back seat reminder.
The Infiniti QX80 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 Durango doesn’t offer a front passenger side knee airbag.
The QX80 Autograph has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Durango doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The QX80 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Durango doesn’t offer backup collision prevention brakes.
The QX80’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Durango and is not available with SXT.
The QX80 has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Durango only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The QX80’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 Durango doesn’t offer a driver alert monitor.
Both the QX80 and the Durango have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available all wheel drive.
The Infiniti QX80 weighs 578 to 1335 pounds more than the Dodge Durango. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
