  Yes its the blue ferrari - but not quite. The Sauber runs on the current (2004) Ferrari engine due to the 2004 "one engine per weekend" rule. They also use the Ferrari gearbox, Bridgestone tyres are a given and on the chassis front, well they *tell* us that the Sauber chassis has a 4 inch shorter wheelbase than the ferrari but you couldnt tell by looking. So what IS the crucial difference between Sauber and Ferrari that put Sauber barely ahead of Minardi (and (gasp) Mclaren) and Ferrari clearly the leaders of the pack? There is however one crucial difference. Ferrari are using Shell. Sauber urlLink are not.
