The 2003 Mercedes-benz E-class marked a significant redesign for the model, introducing enhanced safety features, particularly in models manufactured after December 2002. These later 2003 models incorporated structural improvements specifically aimed at bolstering occupant protection in frontal offset crashes. It’s crucial for owners and potential buyers to verify the manufacturing date, typically found on the certification label located on or near the driver’s side door, to ascertain if their vehicle includes these critical safety enhancements.
The Insurance Institute for Highway Safety (IIHS) rigorously evaluated the crashworthiness of a 2003 Mercedes-Benz E-Class, equipped with these structural upgrades, through a 40 mph frontal offset crash test against a deformable barrier. The results offer valuable insights into the vehicle’s safety performance.
2003 Mercedes-Benz E-Class Crash Test Performance Breakdown
The IIHS crash test assessed various aspects of vehicle safety, providing an overall evaluation and detailed ratings across key criteria. The 2003 Mercedes-Benz E-Class demonstrated commendable performance in this rigorous assessment.
Impressive Overall Safety Rating
The 2003 Mercedes-Benz E-Class achieved the highest possible Overall Evaluation rating of Good (G). This top-tier rating signifies the vehicle’s robust performance in protecting occupants during a frontal offset crash.
Robust Structure and Safety Cage
A critical component of vehicle safety is the integrity of its structure. The 2003 Mercedes-Benz E-Class earned a Good (G) rating for Structure and Safety Cage. This indicates that the vehicle’s structural design effectively maintained its integrity during the crash, providing a stable safety cage for the occupants.
Excellent Driver Injury Measures
The crash test meticulously measured potential driver injuries across different body regions. The 2003 Mercedes-Benz E-Class consistently showed Good (G) ratings across all Driver Injury Measures:
- Head/Neck: The protection for the head and neck region was rated as Good, indicating a low risk of injury to these critical areas.
- Chest: Similarly, the chest protection was rated Good, suggesting effective mitigation of chest injuries in a frontal offset crash.
- Leg/Foot (Left & Right): Both left and right leg/foot injury measures received Good ratings, highlighting the vehicle’s ability to minimize lower extremity injuries.
Driver Restraints and Dummy Kinematics
The effectiveness of the driver restraints and the dummy’s movement during the crash are crucial indicators of safety system performance. The 2003 Mercedes-Benz E-Class received an Acceptable (A) rating in this category. The dummy movement was generally well-controlled. However, during rebound, the dummy’s head made contact with the B-pillar and window frame after moving partway out of the open window. Despite this contact, head acceleration remained low.

Technical Measurements: Occupant Compartment Intrusion and Driver Injury Details
Detailed technical measurements from the crash test provide a deeper understanding of the 2003 Mercedes-Benz E-Class’s structural performance and driver injury metrics.
Occupant Compartment Intrusion on Driver Side
These measurements quantify the extent of intrusion into the occupant compartment, critical for maintaining survival space.
| Evaluation criteria | Measurement |
|---|---|
| Footwell intrusion | |
| Footrest (cm) | 3 |
| Left (cm) | 7 |
| Center (cm) | 9 |
| Right (cm) | 4 |
| Brake pedal (cm) | 5 |
| Instrument panel rearward movement | |
| Left (cm) | 0 |
| Right (cm) | 0 |
| Steering column movement | |
| Upward (cm) | 1 |
| Rearward (cm) | -2 |
| A-pillar rearward movement (cm) | 1 |
The measurements reveal minimal intrusion into the occupant compartment. Notably, there was no rearward movement of the instrument panel, and only minor movement in other areas, indicating a strong and stable occupant cell.
Driver Injury Measures – Detailed Data
Specific injury measures recorded on the crash test dummy offer precise data on potential injury levels.
| Evaluation criteria | Measurement |
|---|---|
| Head | |
| HIC-15 | 230 |
| Peak gs at hard contact | 40 |
| Neck | |
| Tension (kN) | 1.4 |
| Extension bending moment (Nm) | 24 |
| Maximum Nij | 0.30 |
| Chest maximum compression (mm) | 35 |
| Legs | |
| Femur force – left (kN) | 2.8 |
| Femur force – right (kN) | 2.4 |
| Knee displacement – left (mm) | 0 |
| Knee displacement – right (mm) | 0 |
| Maximum tibia index – left | 0.45 |
| Maximum tibia index – right | 0.71 |
| Tibia axial force – left (kN) | 1.7 |
| Tibia axial force – right (kN) | 3.8 |
| Foot acceleration (g) | |
| Left | 48 |
| Right | 60 |
These detailed injury measures are all within acceptable limits, indicating a low probability of significant injuries in a similar real-world frontal offset crash scenario for the 2003 Mercedes-Benz E-Class models manufactured after December 2002.
Conclusion: 2003 Mercedes-Benz E-Class – A Safe Choice Post-December 2002
The IIHS crash test results for the 2003 Mercedes-Benz E-Class models built after December 2002 clearly demonstrate a high level of safety performance in frontal offset crashes. With “Good” ratings across the board for structural integrity and driver injury measures, and an “Acceptable” rating for restraints, the 2003 Mercedes-Benz E-Class stands out as a safe vehicle in its class, particularly for models incorporating the crucial structural enhancements introduced post-December 2002. These findings reinforce the Mercedes-Benz commitment to safety and provide valuable information for individuals considering a 2003 E-Class.
