As maybe most of you might know by now, the crash test is separated into different sections with different demands.
The first part is that while crashing the first 15cm of the crash structure you must not exceed 10g deceleration.
The second part is while absorbing the first 60kJ there must be no more than 20g deceleration.
Mercedes' interpretation to the first part was this:
The 15cm start at the leading edge of the front wing. So before you actually reach the nose-tip the first 15cm will already be gone. Having less than 10g while effectively crashing the front-wing was no problem.
But the FIA didn't agree with that interpretation. They demanded the first 15cm to start with the nose-tip.
So the challenge for Mercedes was to design a nose that is really short, must be very soft at the first 15cm and not too stiff after that in order to pass the second part as well.
That's why their band-aid was to effectively extend the nose-cone for the first 15cm until hey were able to pass the test with the short one.
