Newey not ruling out new developments to Red Bull's RB7

Newey, whose RB6 and RB7 designs have scooped up the last two drivers' and constructors' world titles with Sebastian Vettel, insisted that all focus is now going into the new RB8 project which he said would likely be influenced by the change in blown diffuser regulations for next year.

"All our research is on next year, but if we find something that comes out of that in regards to this year's car we may choose to do so depending on whether it could give the game away," he said at the team's headquarters during its world title media event in Milton Keynes.

"There aren't huge regulation changes for next year except on the exhaust positioning, and that does have a huge knock-on effect of the car.

"We're working our way through that restriction and trying to find the best solution."

Newey added that he had derived enormous satisfaction from the success his design team's cars have generated and said that it was all the more special having been a part of the team as it grew from a midfield squad to world beaters.

"It's been so special because I joined Red Bull in its infancy, and then we grew the team with the hope of winning races and maybe championships," he said. "To prove this year that 2010 wasn't a flash in the pan was just as special.

"When I joined we had Jaguar employees, Christian [Horner] started employing people and it's really been about getting everyone to work together and gel. 2007 and 2008 we weren't quite there, we were still growing the infrastructure.

"It takes time - at Williams and McLaren my job was very much design-based, but we realised it wasn't working here. What we have achieved is fantastic. There is a fantastic atmosphere born out of passion."
