Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Mercedes E class was redesigned for the 2010 model year. Beginning with 2014 models manufactured after January 2014, the footwell area of the occupant compartment was strengthened to improve occupant protection in small overlap frontal crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).

Structure

The driver space was maintained well, with maximum intrusion of the lower interior of 8 cm at the footrest and 7 cm at the parking brake pedal. Upper interior intrusion measured 2-3 cm at the upper hinge pillar and instrument panel.

Injury measures

Measures from the dummy indicate that injuries to the left and right lower legs would be possible in a crash of this severity. The risk of significant injuries to other body regions is low, including head injury risk from the A-pillar hit.

Restraints and dummy kinematics

The dummy’s head mostly remained in contact with the frontal airbag, but the head still hit the A-pillar because the seat belt allowed excessive forward excursion of the dummy's head and torso. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects.

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Mercedes E class was redesigned for the 2010 model year. Frontal ratings are assigned by the Institute based on a test conducted by Mercedes as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the roof rail hit was negligible.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head hit the roof rail.

Side crash test ratings can be compared across vehicle categories.

The Mercedes E class was redesigned for the 2010 model year. Beginning with 2010 models built after April 2010, design changes were made to the front and rear door trim to improve occupant protection in side impact crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof and a side airbag that deployed from the seat.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
