The shaped charge hit the vehicle they was in (Italian equivalent to the HMMW) right under the passenger area and completely destroyed it. Then the vehicle caught fire. I guess that a shaped charge hitting a hummvee anywhere and destroying it is quite realistic...
I wonder how many kilo's of explosives were used in that shaped charge
An AT4 for example only packs about half a kilo of high explosives, which is hardly enough to crumble anything and definately not a hummer, so I guess something more has happened, or that a serious amount of explosives where used. Mind, that crew being close to and not protected from a blast of 0.5 kilos of high explosives cut still be seriously damaged and maybe even killed.
On comparison to the AT4, a classic AT-mine, which destroys by utter force, and which I guess most IED's are modelled around, packs around 10 kilos of high explosives, which by any means would make a hummer stop. Even so, soldiers have run into such beast in lighter vehicles than hummers and survived the encounter (Needless to say that the vehicle did not

).
My point being, that most likely the shaped charge you quote as the main destructive force, propably was way more powerful and way less sophisticated, than the ones used in warheads. And that I've been told that a shaped charge from a warhead would likely penetrate right through a crew compartment without killing all the crew. And finally that a shaped charge does not make anything blow up, unless it hits some other explosives in its target. I won't deny however, that a shaped charge might set burnable objects on fire
Btw, check out this excellent source on shaped charge theory:
