Rating applies to 2008-09 models

Tested vehicle: 2008 Mercedes-Benz C 300 4-door

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.

Restraints and dummy kinematics

Action shot taken during the Institute's frontal offset crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well (Institute test car shown).

Dummy movement was well controlled in both tests. During rebound, the dummy's head hit the roof rail, as indicated by smeared greasepaint.

Forces on the left knee were high enough to indicate the possibility of injury in the Institute's test (shown). In Mercedes' test, forces on the right lower leg were just above the threshold indicating the possibility of injuries.

Side

Rating applies to 2009-14 models

Tested vehicle: 2009 Mercedes-Benz C 300 4-door with standard front and rear head curtain airbags and standard front seat-mounted torso/pelvis airbags

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.
