Renault could supply four F1 teams in 2011

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.
