Renault is the only team that currently supports FIA president Max Mosley's proposal for a common engine in F1.

Mosley's suggestion has been a major subject of discussion in the latest meetings of the formula one teams' alliance FOTA, according to the German magazine Auto Motor und Sport.

The report said only Renault currently backs the plan, but team customer Red Bull might also fall in line should the issue go to a vote.

Under the FOTA statutes, rule changes such as the common engine proposal require at least 7 of the 10 teams to vote in favour.

Auto Motor und Sport, meanwhile, reports that F1 chief executive Bernie Ecclestone is annoyed with McLaren.

Of the 20 race drivers, only Lewis Hamilton and Heikki Kovalainen reportedly turned down an invitation on Friday to attend a lunch with Singapore president Sellapan Rama Nathan.
