Lower leg/foot Good (G)
Driver restraints and dummy kinematics Acceptable (A)

The C300 earned a “Good” rating overall in the driver-side small overlap front test, indicating robust structural integrity and occupant protection. The structure and safety cage held up well, and injury measures for the head/neck, chest, hip/thigh, and lower leg/foot were all rated “Good”.

However, the driver restraints and dummy kinematics received an “Acceptable” rating. The test results indicated that while the dummy’s head did contact the frontal airbag, it rolled to the left due to excessive forward movement allowed by the seat belt. Despite this, the side curtain airbag deployed effectively, providing sufficient forward coverage to protect the head from side structure and external objects.

The post-crash analysis of the dummy’s position relative to the door frame, steering wheel, and instrument panel showed that the driver’s survival space was well-maintained. This is a critical factor in occupant safety, indicating that the structural design of the 2020 Mercedes-Benz C300 effectively protects the driver’s space during a severe frontal collision.

Despite the generally good performance, the head movement observation highlights an area for potential improvement. The dummy’s head rolled partially to the left, moving towards a gap in coverage between the frontal and side curtain airbags. This suggests a minor vulnerability in head protection during this specific type of crash scenario.

Technical measurements from the test further support the “Good” rating for structural performance and driver injury measures. Intrusion into the occupant compartment was minimal, and measured injury metrics for the head, neck, chest, femur, and tibia were all within acceptable limits, indicating a low risk of significant injuries in this type of crash.

Small Overlap Front Crash Test: Passenger-Side

The passenger-side small overlap frontal test mirrors the driver-side test but assesses protection for the front passenger. This test is crucial as passenger-side protection can sometimes differ from driver-side protection.
