Oct.21 (GMM) Max Mosley has rejected the proposal of F1's six car manufacturers for a new engine formula for 2010.



The FIA president had requested the carmakers' suggestions amid the warning that he might simply devise his own new rules.



We reported recently that BMW, Ferrari, Honda, Mercedes-Benz, Renault and Toyota had agreed to a 675 hp formula that involves four-race engines and an energy recovery 'boost' button.



Mosley told the German newspaper Die Welt: "We would have supported it, if the private teams would have been guaranteed an engine supply for 10 million euros rather than 15 million per season.



"Unfortunately the manufacturers did not accept it."



Mosley added that it is crucial that the cost of the regulations is reduced, because "some manufacturers are no longer prepared to spend 200m euros a year" on engines alone.



He said: "We have proposed an alternative. Use the current engines, but freeze them technically for ten years, until 2018."



Mosley said the FIA's counter-proposal would involve changing the engines every two races, as is the practice now, instead of every four.



He said the proposal would save the manufacturers 100m euros per year.



"We submitted our proposal last week and are waiting for their response," Mosley revealed, adding that if the carmakers cannot reach a compromise, the FIA's proposal will simply be mandated.
