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

The Mercedes C class was redesigned for the 2008 model year. Beginning with 2010 models, an airbag for the driver's knees was added to improve occupant protection in frontal crashes.

Structure

The driver's space was seriously compromised by intruding structure. Footwell intrusion measured as much as 32 cm at the footrest and the instrument panel intruded more than 10 cm. The dummy's right foot was trapped beneath the brake pedal, and the pedal had to be cut off to free the foot.

Injury measures

Measures from the dummy indicate that injuries to both the left and right lower legs would be likely in a crash of this severity. The risk of significant injuries to other body regions is low.

Restraints and dummy kinematics

The dummy’s head remained in contact with the frontal airbag, but its head still moved toward the intruding A-pillar because the seat belt allowed excessive forward excursion of the dummy's head and torso. The side curtain airbag did not deploy, leaving the dummy's head vulnerable to contact with side structure and outside objects.

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

The Mercedes C class was redesigned for the 2008 model year. Beginning with 2010 models, an airbag for the driver's knees was added to improve occupant protection in frontal crashes. 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 low.

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 C class was redesigned for the 2008 model year. Beginning with 2009 models, the front-seat mounted side torso airbags were modified to include an additional chamber to protect the pelvis in side-impact crashes.

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.
