Rumours about the health of the team currently known as Renault refused to disappear at Silverstone.

Boss Eric Boullier recently dismissed the rumours, hinting that they were triggered mischievously at Monaco by his predecessor Flavio Briatore.

But six weeks later, there was once again similar talk in the paddock of the British Grand Prix, not long after Williams was announced as engine supplier Renault Sport's newest partner team for 2012 and beyond.

Apart from the continuing naming connection, a customer engine contract and their historical links, the French marque is no longer involved with the Lotus-sponsored Renault team.

And Germany's Auto Motor und Sport reports that the team might even be powered by Cosworth engines next year.

"This is fiercely denied by those in charge," the magazine acknowledged.

However, the Williams situation is perhaps relevant, particularly with the fanfare of the Renault engine announcement involving former works champions Nigel Mansell, Damon Hill and Jacques Villeneuve at the team's Grove headquarters last week.

As for Lotus Renault, "poor results and apparently still pending payments for the engines do not make things any better", Auto Motor und Sport added.
