All Ferraris look the same to me but still I'm not sure that Rossi was the only one driving old the old one. The nose on third pic looks like F2005 and Schumacher is in some older car too. Both car from first 2 pics are the same but that is not one and the same car but 2 cars (check the airbox camera). Why would Ferrari bring so much old cars to testing anyway?
All these pics show an F2004 but they have different engines.
MS drove the F2004 with V8 engine, Rossi was driving an F2004 with a V10, detuned according to official reports (unofficially on the other hand...); he always drove only the F2004, it wouldn’t be worth to have him to “learn” the F2005.
Main reason MS and Massa still use F2004 is that Ferrari never modified a F2005 to install the V8, the first track test of the V8 was in mid August and they probably started to work on preparation of the interim car for it a couple of months earlier at least, it was just logical to use an old and well known F2004 back then, after all the F2005 race debut was in April and probably they didn’t have a 2005 chassis and spare parts to “sacrifice” for the V8.
Then, as Spencifer_Murphy said there’s the tyre thing.
Obviously F2004 is designed for the 2004 aero rules but according to MS they expect the aero performance of the 248F1 to match the F2004 so data should be useful anyway.
