The world champion marque said it would use a modified version of the F2004 until April, allowing more time to 'perfect' the new model for a brand new technical code.
Schumacher,36, said: "We've done it before and it never proved a disadvantage - (F2004 is) such a good car anyway."
Far from interpreting Ferrari's plan as a scarlet disadvantage, too, is Frank Williams. The wheelchair-bound F1 principal said he is 'deeply worried' about the intention to withhold the 2005 model.
"They've obviously travelled along the same path (as us) and said 'we need to be even cleverer with these rules'. I hope I'm wrong but they could have come up with something very, very clever." -GMM
