Williams to use Cosworth engines in 2010

Williams confirmed on Friday that they have signed a long-term engine partnership with Cosworth Limited. The team announced earlier this month that they would be ending their current arrangement with Toyota at the end of this season.
“Cosworth have impressed us with the quality of their technical team and convinced us that their programme will deliver a competitive Formula One engine,” said Frank Williams, whose team last used Cosworth power in 2006.
“In addition, like Williams, Cosworth is an independent company whose owners share our passion for racing and engineering. We believe that, working together, we will develop not only a competitive racing car for 2010 but also a long-term partnership that can take on the best in Formula One.”
Mark Gallagher, Cosworth's general manager for Formula One, added: “Cosworth is delighted to be renewing our partnership with Williams. We look forward to forging a long-standing relationship, not only for the supply of competitive Formula One engines, but also in the joint development of new technologies that have wider application outside of Formula One.”
Cosworth powered both Williams and Toro Rosso in 2006, after which they departed the sport. Next year their engines will also be used by the four new Formula One entrants, Campos Meta, Lotus, Manor and the US F1 Team
