Formula 1 teams are due to meet with FIA president Max Mosley in London today to try and reach a last-minute deal over entries for next year, AUTOSPORT has learned, with the governing body having made clear the compromises it is willing to offer.
With the entry list for the 2010 championship due to be announced by the FIA tomorrow morning, efforts are increasing to reach a resolution that will head off the threat of current manufacturer teams walking away from F1.
Although there have been suggestions in the past few days that the two sides are edging near a resolution, there still appears to be differences between the two parties about the way forward for next year.
However, AUTOSPORT has learned that Mosley is willing to soften the FIA's approach to next year - which includes scrapping a two-tier category - even though he insists a budget cap must be in place in 2010.
In a letter Mosley sent to Ferrari president Luca di Montezemolo following his last meeting with teams in Monaco, a copy of which has been seen by AUTOSPORT, Mosley said that there was some ground for manoeuvre in what the FIA would be willing to accept for next year.
"We can agree that all teams race under the same 2010 rules," said Mosley, referring to the original proposal for a two-tier F1 that had been a major bone of contention for a lot of teams.
"These would be as published, but with the technical and sporting advantages originally offered to cost-cap teams deleted."
Rather than having performance benefits, the FIA said it was willing to give new teams the opportunity to work on technology transfer deals with established outfits - as has been hinted about by Frank Williams in recent days.
Mosley added: "Instead of these advantages, we will facilitate know-how transfer between certain current teams and new entrants at least for 2010 and possibly for 2011."
One thing Mosley is not willing to back down on though is the introduction of a budget cap - even if the figure is made very high for next year.
He said he was willing to propose: "A cap in 2010. This could be as high as 100 million Euros, but we must have a cap and we must have certainty... For 2011, again we must have certainty with a cap at £40 million (or if preferred 45 million Euros)."
However, Mosley said that a compromise could be introduced whereby one highly paid member of staff would be allowed to be outside the budget cap - which would help those outfits who have star names, like Adrian Newey or Ross Brawn, on board.
Furthermore, the FIA said it was willing to sign a Concorde Agreement 'broadly' along the lines of the version sent to it prior to the Monaco Grand Prix, plus a renaming of the cost cap - which has been a big issue for the teams.
