Hamburg, Oct 15
The Williams Formula One team will end its contract with engine supplier Toyota after the season and will have a different engine in 2010.
Toyota supplied Williams with engines since 2007. Renault and Cosworth have been mentioned as possible partners next year with an announcement expected soon.
"At a time of great difficulty for us as a team, Toyota stepped forward and agreed to supply us with engines," said team boss Frank Williams, naming Toyota "a very decent partner who have always respected our independence."
Toyota motorsport head Tadashi Yamashina said: "We respect the wishes of Williams to look for other opportunities and wish them well for the future."
