They of course test with the version achieving the highest score. It's not like bmw don't know in advance how it will perform.

Yes. Though greater mass equals more momentum at same velocity; heavier cars are at an advantage in a collision with lighter ones.
I expect therefore the advantage of one feature (more crumple) is counteracted by the other (lighter) and vice versa. Unless of course it's a solid object in which case lighter would be easier to stop and momentum would be a disadvantage!
