Newey: No double diffuser until Monaco

Red Bull's technical boss Adrian Newey has ruled out the introduction of a double-decker diffuser in the team's race-winning RB5 before the Monaco Grand Prix next month.

The Renault-powered car, driven by Sebastien Vettel, gave Red Bull Racing its maiden Formula 1 victory at last weekend's Chinese Grand Prix.

Vettel's team-mate Mark Webber finished in second as a car not fitted with a double-decker diffuser won a race for the first time this year.

Newey, however, decided not to travel to China in order to focus on the new floor, but he admits it will be a challenge to make it work properly given the car's rear suspension design.

"As has been speculated, given the design of RB5, it's not the easiest task getting it to fit the car and while we work on this one item, we also need to keep working on the general development of the car, to ensure we don't fall behind in other areas," said Newey.

"The unique feature of the Red Bull cars is the pullrod rear suspension, which is a good solution when you don't have a double-diffuser. But getting it to work with the diffuser will be more difficult. We won't have a double-diffuser before Monaco.

"It will certainly involve a lot of work," he added. "The challenge now is to try and integrate the new diffuser into the rest of the car. But I don't regard it as a shame, I see it as another challenge.

"Unfortunately, it will involve some more late nights! That's Formula One: you can't afford to sit around and feel sorry for yourself, you just have to get on with it.

"There is no doubt that a double-diffuser does give performance. How much performance depends on how you interpret the regulations and how you adapt it to suit your own car, so that some teams will get more out of it than others. It is worth doing for everyone on the grid. Our challenge is to adapt one to work on our car."
