Mercedes-Benz M-Class Achieves Top Safety Pick

The Mercedes-Benz M-Class has succeeded in passing what is now the stricter crash test carried out by the American Insurance Institute for Highway Safety (IIHS), picking up the "Top Safety Pick+" (TSP+) award in the process.

The premium SUV already received five stars in the U.S. NCAP and Euro NCAP tests in 2012. As a result of this latest award, the M-Class has again achieved the best marks and defended its leading position in three of the world's most important and most demanding safety ratings.

Overall, as part of the M-Class development, Mercedes-Benz tested no less than 36 completely different load cases under real test conditions. This included comprehensive simulations as part of the digital prototype phase.

A new element of the rating applied by the IIHS – an organization supported by various vehicle insurance companies – is the so-called "small-overlap test."

As part of this, a front-impact test is carried out at 64 km/h with a face contact ratio of 25 percent. This is designed to simulate a front impact in which the driver tries to swerve to the side but does not quite manage to avoid the vehicle coming in the opposite direction.

Model-year 2014 vehicles must pass this test to receive the "Top Safety Pick" award. Out of the total of five crash tests carried out by the IIHS (frontal 40 percent, frontal 25 percent, side impact, whiplash and roof crush), only the small-overlap test may be assessed with a rating of ACCEPTABLE, while all other tests must be performed with a best mark of GOOD in order to achieve the new TSP+ award – something which the M-Class has now succeeded in doing.

The NCAP (New Car Assessment Programme) ratings, on the other hand, are based on another face contact ratio in the case of the front impact: for the U.S. NCAP for example, in the front impact the vehicle is driven into a fixed barrier at a speed of 56 km/h with a full face contact ratio.

In contrast, the front impact of the Euro NCAP is carried out against a deformable barrier at a speed of 64 km/h and with a face contact ratio of 40 percent (offset crash test).

In addition, different side impact tests and tests on child and pedestrian safety are included as part of the ratings, and the standard of equipment with assistance systems is also increasingly being incorporated into the assessment.
