MONTE CARLO, Monaco, May 27, 2012 (AFP) - Red Bull technical boss Adrian Newey defended the design of his team's race-winning car after Australian Mark Webber's triumph in Sunday's Monaco Grand Prix.
Pre-race rumours suggested that at least three of their major rivals were poised to protest about a newly-created 'hole' in the floor of the Red Bull - claiming it contravened the technical regulations and create more downforce.
But team boss Christian Horner said: "The car complies with the regulations. We're happy with that. It's the nature of the sport that this can happen."
And Newey said: "This issue first arose after the Bahrain Grand Prix and we have a letter from Charlie Whiting (the official race director) saying categorically that it's legal,so we're not worried."
The defending champions found themselves at the centre of a new technical row, just hours before the start of Sunday's race.
Rivals - believed to include McLaren, Ferrari and Mercedes - were said to be unhappy about the design of the floor of their cars.
According to paddock sources close to the engineering staff of those teams, they were unhappy at the creation of a 'hole' in the floor of Red Bull's RB8 car, just ahead of the rear wheels.
None of the teams were prepared to make any official complaint about the floor design, but said instead that they hoped it might be investigated.
Red Bull said it had no official comment to make on the issue.
The 'hole' may contravene article 3.12.5 of F1's technical regulations. It was created to improve the airflow under the car and to increase the amount of rear end down-force, which in turn would improve the car's handling
