May 15 (GMM) Williams has no plans to split with its engine supplier Toyota in the near future.

The British team joined forces with the Japanese manufacturer last year, and now collaborates with Toyota's works formula one outfit on such matters as gearbox design, and advice about formula one politics.

But even though the relationship is not the same as Williams' past works alliances with Honda, Renault or BMW, team co-owner and principal Sir Frank Williams says he is happy with the current situation.

"Toyota cares for us very well," the 66-year-old told Switzerland's Motorsport Aktuell in an interview.

"We are in no way insecure. They have really very good people. We are very happy with them and look forward to a long collaboration with Toyota," Williams added.

At the Turkish grand prix last weekend, however, Williams acknowledged the difficulty of being a private team in formula one at the moment, and said it is unlikely that Super Aguri's garage will be filled any time soon.

"If a privateer was trying to enter, financially you would find it very difficult right now, assuming you read the Wall Street Journal and the Financial Times, to raise money, to raise capital," Sir Frank explained.
