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 Expedition 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 middle row seatbelts optional on the Expedition inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The G-Class doesn’t offer inflatable seatbelts.
Over 200 people are killed each year when backed over by motor vehicles. The Expedition offers an optional Reverse Brake Assist 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 Expedition (except STX/XLT) offers an optional 360-Degree Camera 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 Expedition and the G-Class have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front 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, driver alert monitors and available all wheel drive.
