You guys need to polish your concepts straight up, the rear of any car is stronger than it's front. The corolla did what should have been done, crumple up. The formula for momentum is p=mv. Mass x velocity. Now a s400 and the corolla weigh much differently, I can't see any damage to the MB so maybe this is a crap shoot. Regardless the concepts remain the same and if this was to happen in real life, the corolla would almost always sustain more damage due to the mass of the MB. Only if it's velocity was somehow much more than that of the MB to cause equality of momentum would the mercedes have probably sustained similar amount of damage!
