The Formula 1 circus at the moment is busy trying to figure out which team will be using which engines in 2010 and the word is that Williams wants a change. The Toyota engines are not bad but the importance of fuel efficiency will increase next year as there will be no refuelling allowed and we hear that the team is looking at alternative options. The first choice is probably Mercedes-Benz but with a deal expected to be announced soon between Mercedes and Red Bull Racing, Renault has engines up for grabs. Mercedes is restricted to four supplies (although there are questions about whether such a restriction can be applied allowing for European competition law) and with deals in place with McLaren, Brawn GP, Red Bull Racing and Force India, there would not be room for a Williams deal. However, Force India needs to start paying its bills if it wants the relationship to continue. If that does not happen then the second year of the contract could be cancelled and the fourth engine supply might be available.
If the BMW Sauber team does survive it is expected to use Ferrari engines, while potential newcomers Epsilon Euskadi is also expected to run Ferrari engines if it gets an entry.
This would leave Toyota without any customers but there is always the possibility that one of the new teams might buy its way out of the Cosworth deals because of performance-related fears in 2010 and Toyota would be a good place to land.
