About the original moderate overlap front test

Tested vehicle: 2005 Mercedes-Benz C 240 4-door with standard front and rear head curtain airbags and standard front and rear door-mounted torso airbags
Rating applies to 2006-07 models

The Mercedes C class was redesigned for the 2001 model year. Modifications were made to the front seats and side airbags beginning with 2005 models to improve occupant protection in side-impact crashes. Beginning with 2006 models, the side airbags designed to protect rear passengers' torsos became optional (standard in 2005 models).
