It is a combination that between 1992 and 1997 successfully yielded nine world championship crowns - five drivers' titles and four constructors' laurels - and now Williams and Renault could be set to be reunited, it seems, with the French manufacturer understood to be in demand regarding the supply of customer engines from next year.

Having affirmed that it is capable and willing to provide engines to more than just its own team and F1 2010 pace-setters Red Bull Racing as it does at present, it appears Renault is being courted by hopeful GP2 Series graduate ART Grand Prix, 2010 newcomer Lotus and now also Williams, which has been open in its dissatisfaction with the Cosworth powerplants it is using this year.

With separate rumours having linked former Renault F1 executive director of engineering Pat Symonds to a consultancy role in the design of the Grove-based outfit's 2011 FW33 contender [see separate story - click here], the speculation does seem to make sense, and the R?gie's head of engine operations Remi Taffin confirmed that all options are open.

"We still do not know how it will be in 2011," he told Italian magazine Autosprint, "but we do know that we have the ability to assist more than two teams."
