نص أصلي - انجليزي - recently read that

I recently read that the 159 and Brera will lose weight until they are given a facelift in 2008/2009. This year they would lose 45kg and next year 100kg and another 100kg when they are given a facelift in 08/09. this is because Alfa romeo have now realised that they made the two cars too heavy. the weight loss will be cause by making certainb things out of aluminum.
