Red Bull passes latest wing flexibility tests

Red Bull's car was declared legal on Friday after undergoing the latest wing and floor flexibility tests at Spa-Francorchamps.

Amid suggestions the front of the RB6 is too low at the front when at speed, the FIA ramped up the wing flexibility test for the Belgian event.

This was carried out on championship leader Mark Webber's car, as well as the McLaren of Lewis Hamilton, after Friday practice.

The FIA confirmed that the cars' wings and floors "were found to be in conformity" with the regulations.

"Our car has complied with the rules at every race so far and it will comply here," team boss Christian Horner said earlier.

"We take all the talk about our car as a compliment, it shows the others don't know what we're up to," he told the BBC on Friday.

The next hurdle for Red Bull will be the tougher floor tests and rules to take effect at Monza in two weeks.

Horner added: "Adrian Newey seems pretty relaxed about it. It will only affect us as much as any of the other teams."

Mercedes' Ross Brawn admitted on Friday that some teams, perhaps also Ferrari, have not been happy with the recent insinuations about flexing cars.

"I know some of the teams involved were not very happy with comments I made, or McLaren made, but then I was not happy about comments they made about the double diffuser last year," he said.

"It is the nature of Formula One," insisted Brawn.
