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 the 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-Benz 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 are based on averaged results from both tests.
