Red Bull’s chief designer Adrian Newey disclosed that the 2011 car will not have a radical new design but rather, it will be an evolution of the championship-winning RB6. Ever since new regulations were put in place in 2009, Red Bull has come up with race-winning cars and was able to complete both seasons with the fastest chassis.
Double diffusers will not be permitted in 2011 and the car's weight distribution will be set by the FIA and teams will have to hold bulky KERS units in the chassis; however, Newey insists that the RB7 won't require a drastic rethink. Newey told laola1.at that the DNA would not be changed and that the RB6 was “basically an evolution of the last car.”
In the past, Red Bull’s rivals have raised complaints about the legality of Newey’s car -- something that he expects to happen again for the 2011 car. He explained that when the car’s leading in F1, people think that you’re cheating.
With regards to the major regulation changes in 2013, Red Bull team principal Christian Horner said he’s not ruling out the possibility that the team will switch its engine supplier or even build its own engines.
In 2013, Formula One will use 1.6-litre, four-cylinder, turbocharged engines. In relation to this, Red Bull team owner Dietrch Mateschitz has implied that there will be a major change.
In a recent interview with laola1.at, Horner talked about the importance of keeping all options open, noting that this is one of Mateschitz's great strengths. Horner also said that an F1 engine deal with car giant Volkswagen is considered more likely.
