Small Overlap Front Crash Test: Driver-Side Assessment
The small overlap front crash test simulates a challenging real-world scenario where only a small portion of the vehicle’s front end impacts another vehicle or a stationary object. Let’s examine how the Mercedes-Benz C300 2020 performed in the driver-side small overlap front test.
Driver-Side Performance Metrics:
| Evaluation Criteria | Rating |
|---|---|
| Overall | Good |
| Structure and Safety Cage | Good |
| Driver Injury Measures | |
| Head/Neck | Good |
| Chest | Good |
| Hip/Thigh | Good |
| Lower Leg/Foot | Good |
| Driver Restraints & Kinematics | Acceptable |
The Mercedes-Benz C300 2020 achieved a “Good” rating in the small overlap front crash test for structural integrity and driver injury measures. This indicates robust protection for critical areas like the head, neck, chest, hip, thigh, and lower leg/foot in this type of collision.

However, the driver restraints and dummy kinematics were rated as “Acceptable”. The test analysis noted that while the dummy’s head contacted the frontal airbag, it exhibited excessive forward movement due to seat belt slack, causing it to roll to the left. Despite this, the side curtain airbag deployed effectively, providing sufficient forward coverage to protect the head from side structure and external object impacts.
