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 Passport doesn’t offer pre-crash pretensioners.
The GLC has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Passport doesn’t offer front seat center airbags.
The GLC has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Passport doesn’t offer a whiplash protection system.
The GLC has standard Post-Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Passport 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.
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 Passport doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the GLC and Passport 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 Passport’s Cross Traffic Monitor doesn’t automatically brake.
Both the GLC and the Passport 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, driver alert monitors, available all wheel drive, lane departure warning systems and around view monitors.
The Mercedes GLC has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” to “Good” score in the revised pedestrian crash prevention test. The Passport has not yet been evaluated by the IIHS for 2025.
