Button: Red Bull's pace was affected by new tests

The flexible cars controversy slowed down the previously dominant Red Bull team at Spa-Francorchamps, according to Jenson Button.

Although the Austrian owned team claims the long straights of the Belgian circuit simply did not suit the RB6, McLaren's Button suspects Adrian Newey had to modify the car to meet more stringent bodywork flexibility tests.

Button's boss Martin Whitmarsh, and Mercedes' Ross Brawn, said last weekend that they thought the front wings on the Red Bull and Ferrari cars were flexing less visibly than they had in Hungary earlier in August.

"I think Red Bull's pace was affected by the new tests," said the reigning world champion.
