The AMG GLB’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Grand Cherokee doesn’t offer pre-crash pretensioners.
The AMG GLB offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Cherokee 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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the AMG GLB. But it costs extra on the Grand Cherokee.
Both the AMG GLB and Grand Cherokee have rear cross-traffic warning, but the AMG GLB has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Grand Cherokee’s Rear Cross Path Detection doesn’t automatically brake.
Both the AMG GLB and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
The Mercedes AMG GLB has a better fatality history. The AMG GLB was involved in fatal accidents at a rate 39% lower per vehicle registered than the Grand Cherokee, according to the Insurance Institute for Highway Safety.
