Audi RS6 Avant auctioned at the home of Elton John

A unique RS6 Avant with a personalised interior autographed by the Oscar-winning actress Gwyneth Paltrow has sold at auction for £120,000 (S$230,975) at the annual Elton John White Tie & Tiara Ball, held at the home of the singer/songwriter and his partner David Furnish. Every penny from the auction of the Audi supercar will go to support the work of the Elton John AIDS Foundation.

An impressive net total of £3m (S$5,774,394) was raised by the Ball. Guests were invited to bid for the various lots, which included the one-off RS6 Avant complete with a Lunar Silver leather interior immortalised by Paltrow's signature.

The formidable super Avant is currently the most potent Audi available, producing 560bhp and 700Nm, a century sprint time of just 3.9 seconds, and a top speed limited to 250km/h, which can be raised upon request to 304km/h.

Paltrow - who drives an Audi both in character as Pepper Potts in the Iron Man action series, and in real life on the roads of London and Los Angeles - put her stamp on the car earlier in the month by signing it at the model's launch at Audi City in Piccadilly, London. It had been the very first RS6 Avant to arrive in the U.K., ahead of general deliveries in August.

Stars at the White Tie & Tiara Ball included Coldplay, Uma Thurman, Freida Pinto, Elizabeth Hurley and David Walliams. 

"Audi is delighted to donate the unique RS6 Avant for the equally unique White Tie & Tiara Ball. We are thrilled at the benefit it will give to Sir Elton's AIDS Foundation, which does such outstanding charity work, and very proud to be continued sponsors of the Ball," said Jon Zammett, Head for PR for Audi U.K.

Sir Elton John added, "I would like to extend my thanks to Audi for supporting the Elton John White Tie & Tiara Ball for the last 11 years, and for its generosity to the evening's fundraising."
