The Durango has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The GLB doesn’t offer a whiplash protection system.
To help make backing out of a parking space safer, the Durango’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLB doesn’t offer a cross-path warning system.
Both the Durango and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, daytime running lights, blind spot warning systems, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems and front parking sensors.
The Dodge Durango weighs 859 to 1732 pounds more than the Mercedes GLB. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
