BMW Won't Seek Replacement for Williams

The German car manufacturer announced last month that it was buying the Sauber team to enter its own outfit in F1 from the start of 2006, after getting frustrated with Williams' lack of success.

And although negotiations have continued with Williams about them carrying on as a customer team, Theissen said at Silverstone that if the team and the German engine maker do not close a deal by the end of this month, then BMW will not look for a second team to supply engines to.

"There is no decision on the engines for 2006 yet," said Theissen. "You'll have to ask Frank (Williams) if he wants our engines.

"We have told him he must decide by the 30th week of the year, which is three weeks away. If there is no deal, then we will not actively seek another customer."

The only team apart from Williams who have not confirmed their engine plans for next year are Jordan, who are expected to remain with Toyota in 2006.

Of the other non-manufacturer backed teams, Minardi have already confirmed that they will be sticking with Cosworth engines next year, while Red Bull Racing will be switching to Ferrari power-units.
