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 Bronco 4-Door 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 Bronco has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G-Class 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.
The Bronco (except Big Bend/Black Diamond/Everglades) 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 Bronco and the G-Class have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, rear cross-path warning and driver alert monitors.
