There could be more Renault-powered cars on next year's formula one grid than any other engine supplier.
Although the French marque currently supplies its 2.4 litre V8 only to the team that bears its name as well as Red Bull, it is reported that Williams is now close to agreeing a deal for 2011.
There have been reports that the Grove based team is less than fully happy with the returning supplier Cosworth this year, while at the same time Renault has confirmed it is looking to add a team to its customer engine roster.
Also linked with a switch to Renault has been the currently Cosworth-powered new team Lotus, while Cosworth's business director Mark Gallagher recently said he suspects equipping the sport's 13th team for 2011 will be "a Cosworth/Renault competition".
A report by France's Auto Hebdo said it is likely that eight cars on the 2011 grid will be fitted with Renault engines.
"An agreement with Williams is almost done," said the magazine.
