For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Dodge Hornet doesn’t offer pretensioners for its rear seat belts.
The GLC’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Hornet doesn’t offer pre-crash pretensioners.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLC offers optional Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Hornet doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the GLC and Hornet have rear cross-traffic warning, but the GLC has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Hornet’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the GLC and the Hornet have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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, available all wheel drive, lane departure warning systems and around view monitors.
The Mercedes GLC achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Hornet has not yet been evaluated by the IIHS for 2024.
