Red Bull has confirmed that its 2011 car will be a further evolution of the pace-setting cars of the past two seasons.

This year, the championship-winning RB6 was an evolution of the similarly Adrian Newey-penned 2009 car, which although beaten to the title by Brawn was ultimately the quickest package.

And Briton Newey is quoted by laola1.at in Austria: "It (the 2011 RB7) is a further evolution of the current series. The DNA of the car is the same.

"The (2010) RB6 was basically an evolution of the last car; one basically turned into the next."

Asked if the team's rivals will therefore once again spend the season complaining about the legality of the new machine, he answered: "I hope so! Because that would mean we have done a good job again. If you're out the front in F1, everyone always thinks you are cheating," he laughed.

Meanwhile, team boss Christian Horner has backed reports that Red Bull's F1 cars might one day be powered by their own brand of engine.

When Volkswagen was recently linked with an engine supply foray in the future, the closely-aligned Red Bull was mooted as a natural partner.

"We are on stand-by for an interesting partnership," said team owner Dietrich Mateschitz recently. "And even the idea of developing our own engine, I think, is no longer so absurd," he added.

The new formula for 2013 might be the ideal time for Red Bull to split with its current supplier Renault and delve into F1 engine design.

"It is important to keep all the options open," Horner told laola1.at. "This is one of Mr Mateschitz's great strengths."

An F1 alliance with VW, however, might be considered more likely. "With Didi's vision, anything is possible," acknowledged Horner.
