The 2012 (actually since 2009) Mercedes Benz S-Class is made from a bunch of Ultra High Strength Steel. The B-Pillar and rockers are made from Mega High Strength Steel. Make sure you take a look at the screen shot below from Moditech’s Crash recovery System (CRS) and compare it to the other images. Crash Recovery System would have provided some useful information on scene of a MVA that involved a S-Class.
