Renault Sport says that it is open to supplying engines to a fourth team in Formula 1 in 2012, if there is a team out there that would like to use the French units for just one year, before the new 1.6-litre engines arrive in 2013. It is not likely that there will be any takers given the disruption of an engine change and the fact that most teams now have contracts to get them to the end of the current formula. Renault currently supplies the Renault team (although it no longer owns the business), Red Bull Racing and Team Lotus. This would give the French engine company the best possible return on its investment in F1 and help to provide funding for the development of the 2013 engine. The price of the engine would be around $6.5 million, but this would likely be with stipulations about fuel sponsorship, which would rule out any team with a deal with a fuel company other than Total. At the moment there are not many fuel companies in F1. McLaren has a with ExxonMobil, Ferrari with Shell, Mercedes with Petronas and Williams with PDVSA, but beyond that there is only Total, which is a Renault partner. What is fascinating is that only one of these is in the top 10 oil companies in the world, a list dominated by the big national oil companies such as the Saudi Arabian Oil Company and the National Iranian Oil Company. Venezuela’s PDVSA is the odd man odd in fifth place but otherwise F1 oil companies are 14th (Petronas), 17th (ExxonMobil), 20th (Shell) and 26th (Total).
