Red Bull's 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," laughed Newey.
