The Grove-based Williams F1 team today confirmed that its engine partnership with Toyota would end at the end of this season.

Frank Williams, Team Principal, said: β€œAt a time of great difficulty for us as a team, Toyota stepped forward and agreed to supply us with engines for 2007 through to the end of 2009.

"Toyota has been a very decent partner who have always respected our independence and provided us with a first-rate technical product.

"We are proud that we have been able to work with such a great company and we are grateful to the team in Cologne for their support.

"I would like to single out for our thanks the Toyota engineers and technicians who have worked within our race team tirelessly for the past three years.”

Williams said it would confirm its engine partner for 2010 in due course.
