Autocar report - World's safest S-class
I'm not sure how the side impact bars save weight by being deflated, but I think I know what they're getting at.
Existing features such as side impact bars could be inflated by pressures of between 10 and 20 bar, saving weight when they are deflated and allowing for other safety measures to be fitted in the saved space.
