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. Beginning with 2013 models built after December 2012, the side curtain airbags were reprogrammed to deploy in small overlap frontal crashes to further improve occupant protection (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).

Two tests of the C class were conducted, one a 2012 model and the other a 2013 model built after the side curtain airbags were reprogrammed. In the first test, the driver side curtain airbag did not deploy; in the second test, it deployed as intended. The ratings and vehicle specifications listed are for the second test, but because the car's structure was not changed, the structural rating is based on both tests.

Structure

In both tests, the driver's space was seriously compromised by intruding structure. In the second test, footwell intrusion measured as much as 50 cm at the footrest, and upper interior intrusion measured 10-11 cm at the door hinge pillar and instrument panel. The dummy's right foot was trapped by the brake pedal, and the pedal had to be cut off to free the foot.

Injury measures

In the second test, measures from the dummy indicate that injuries to left lower leg would be likely in a crash of this severity. Injuries to the right lower leg would be possible.

Restraints and dummy kinematics

The dummy’s movement was well controlled in the second test. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. 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 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.
