A unique Audi A1 specially painted by Damien Hirst for Sir Elton John's White Tie and Tiara Ball. Audi sponsored the A1 for the auction held last night – making it the eighth consecutive year that the company has supported the AIDS charity event. Close to 700 VIP guests from all over the world converged on the private home of Sir Elton in Windsor, UK, to support his largest annual fundraiser for his AIDS Foundation.

Damien Hirst's A1 was sold for 420 000 Euro ( £350 000 ).

"That's the most exciting object we've ever had on auction at the White Tie," commented Sir Elton John.

The AIDS Foundation of Sir Elton John manages over £14 million in programmes across 15 countries supporting thousands of men, women and children with life saving medication, as well as information, nutrition, education, shelter and support.

The White Tie and Tiara Ball is the most important charity event for the Elton John AIDS Foundation (EJAF). The foundation has earned 48 million Euro since the first ball in 1993.  This is the eighth time Audi has supported the EJAF with auction lots, but Audi has never before donated an art object of this kind.

Jeremy Hicks, Director of Audi UK said: "We're delighted to be able to support Sir Elton John's wonderful charity event with the donation for the auction of a work of art that cannot be replicated,"
