For enhanced safety, the front and middle seat shoulder belts of the Infiniti QX80 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 Mercedes G-Class has only front 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 QX80 are reminded to check the back seat if they opened the rear door before starting out. The G-Class doesn’t offer a back seat reminder.
The QX80 has standard Active Head Restraints (AHR), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the AHR system moves the headrests forward to prevent neck and spine injuries. The G-Class doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The QX80 has standard Backup Collision Intervention that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The G-Class doesn’t offer automatic braking for stationary objects directly to the rear.
The QX80 has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The G-Class 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.
Both the QX80 and the G-Class have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, 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 and available all wheel drive.
