(GMM) Peter Sauber has told customer engine supplier Ferrari that he's thinking about an alternate arrangement for 2006 and beyond, we can reveal. The current two-year contract, although the arrangement commenced almost a decade ago, will end in December next year. It was originally reported that Ferrari intended to conclude the deal so that it could work exclusively with new Russian-Canadian '06 entrant Midland F1. Sauber told us in an exclusive interview that the use of 'cheaper components' with the 2006 introduction of a 2.4 liter V8 formula may open 'different opportunities' for the Swiss-based team. Might that be a suggestion that Sauber, previously on a seemingly futile hunt for a carmaker partner, could build its own V8 engine? Sauber added: ''I will begin to evaluate all potential options, which naturally include Ferrari, at the beginning of the next season.''
