Major Props to whoever figures out why the US spec Fiesta is 114 lbs heavier then the Euro Spec.

So apperantly the reason why, or at least the reason journalists were saying the US spec is 114lbs heavier is becuase of the bumpers and the extra airbags. So I was under the assumption that the euro spec didn't have side curtain and knee airbags but, they do and it isn't an option it's standard. There's no way justthe bumpers add over 100lbs of extra weight from the lttle few inches they add on each end of the car. So wth is with the extra weight then? Someone find out lol.
