The C-Class Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Crown doesn’t offer pre-crash pretensioners.
The C-Class Sedan 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 Crown doesn’t offer front seat center airbags.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The C-Class Sedan offers optional Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Crown doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
To help make backing out of a parking space safer, the C-Class Sedan has standard Rear Cross-Traffic Alert with Active Brake Assist, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the Crown Limited/Platinum/Nightshade offers Parking Support Brake.
Both the C-Class Sedan and the Crown 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, post-collision automatic braking systems, 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 C-Class Sedan has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 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 Crown is only a standard “Top Safety Pick” for 2024, though it hasn’t yet been rated in the updated moderate overlap frontal test, a requirement for the “Top Safety Pick Plus” award.
