For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC Coupe 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 Coupe’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.
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 GLC Coupe are reminded to check the back seat if they opened the rear door before starting out. The Hornet doesn’t offer a back seat reminder.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLC Coupe has 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 Coupe and Hornet have rear cross-traffic warning, but the GLC Coupe 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 Coupe 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, all wheel drive, 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.
