Audi can win in F1 with Red Bull - Berger

May 9 GMM) The latest rumours about Audi are now growing by the day.

Former Ferrari president Luca di Montezemolo poured on fuel just days ago when he said a "mutual friend" had told him Red Bull mogul Dietrich Mateschitz is pushing hard for the Volkswagen brand to enter formula one.

And Gerhard Berger, a confidante of Mateschitz's and a former Toro Rosso co-owner, agrees: "I would say there is a lot of discussion.

"Mercedes in the last two years has put the game up three steps and Renault just didn't invest," he told Britain's Sky. "I doubt that they're going to be able to catch up.

"But somebody like Volkswagen, fresh coming in, I think they would and I'm sure that would be a good story for Red Bull," Berger added.

The Austrian newspaper Kleine Zeitung cited an "insider" who said a "secret formula one engine" is "more or less finished" at Wolfsburg, VW's headquarters.

Berger said in that report: "If Volkswagen decides to come in, they will want to win from day one. And that is only possible with a super team, and the best team of all is Red Bull."

Finally, the Kolner Express tabloid said the suddenly-ousted Ferrari sporting director Massimo Rivola is being linked with Audi, who have already accommodated the former Ferrari team boss Stefano Domenicali.
