Moderate overlap front

Rating applies to 2006-12 models

Tested vehicle: 2007 Mercedes-Benz R 500 4-door 4wd

The Mercedes-Benz R-Class was introduced in the 2006 model year and restyled for the 2011 model year. Frontal ratings are assigned by the Institute based on a test conducted by Mercedes-Benz as part of frontal crash test verification.

Rating applies to 2009-12 models built after September 2008

Tested vehicle: 2009 Mercedes-Benz R 350 4-door 4wd with standard head curtain airbags for all three rows of seats and standard front and 2nd row seat-mounted torso airbags

The Mercedes-Benz R-Class was introduced in the 2006 model year. Beginning with 2007 models, side torso airbags were made standard for second row seat occupants (they were optional in 2006 models). The vehicle was restyled for the 2011 model year.

Two previous tests of a 2008 R-Class were conducted, and measures from the driver dummies in these tests, taken together, indicated that rib fractures would be possible. In response, Mercedes-Benz modified the front door trim panels and seat belts beginning with 2009 models manufactured after September 2008 (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). The tested vehicle was manufactured after the modifications had been made, and forces on the driver dummy's ribs were significantly reduced.

The 2009 and later models built after September 2008 are therefore rated separately, except that the structure rating is based on the two previous tests plus the latest test.

Tested vehicle: 2008 Mercedes-Benz R 350 4-door 4wd with standard head curtain airbags for all three rows of seats and standard front and 2nd row seat-mounted torso airbags

The Mercedes-Benz R-Class was introduced in the 2006 model year. Beginning with 2007 models, side torso airbags were made standard for second row seat occupants (they were optional in 2006 models).

Two tests of a 2008 R-Class were conducted because in the first test, the airbag warning lamp remained illuminated prior to the test, indicating a possible airbag malfunction. Mercedes diagnostics indicated the fault was confined to the second row right torso airbag, opposite the rear dummy's seating position. Nevertheless, the second test was conducted to determine if the airbag fault warning influenced the results. The second test (without a fault warning) produced very similar injury measures, which confirm the validity of the first test. Therefore, all ratings except for structure are based on averaged results from both tests. The structure rating is based on the two tests of 2008 models plus a later test of a 2009 model.
