Oct.24 (GMM) The FIA's World Motor Sport Council routinely met in Paris on Wednesday and ratified an imminent ten-year freeze on formula one engine development.

The news follows reports last weekend that Max Mosley rejected the alternative proposal of the sport's six car manufacturers for the future engine rules.

The manufacturers wanted a 675 hp formula for 2010 and beyond comprising four-race engines and an energy recovery 'boost' button.

But Mosley, the FIA president, rejected the proposal because the carmakers would not agree to supply customer engines to private teams for 10m euros per season.

"There will be a total freeze on engine development for a period of 10 years, starting from 2008," a statement issued by the Paris based FIA announced on Wednesday.

"A change can be made after five years but only with the unanimous agreement of all stakeholders and following a further two year notice period."

The World Motor Sport Council also ratified Spyker's request to change its name next year to Force India, and confirmed that the inaugural Singapore grand prix next September will be staged under lights at night.
