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. Two tests of the C class were conducted, one by the Institute and the other by Mercedes as part of frontal crash test verification. The overall rating of Good is based on review of both tests, which independently result in overall ratings of Good. The ratings and vehicle specifications based on the Institute’s test are shown below.

Injury measures

In each test, measures taken from the head, neck, chest, and one leg indicate low risk of injuries to these body regions in a crash of this severity. Forces measured on the left knee in the Institute’s test indicate that injuries to the knee would be possible, but right leg/foot forces were low. (In the test conducted by Mercedes, left leg/foot forces were low, but forces on the right tibia indicate the possibility of lower leg injuries.) Head acceleration in each test from the roof rail hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled in both tests. During rebound, the dummy's head hit the roof rail, and in the Institute's test, also the sunvisor and grab handle.

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.
