The Red Bulls of Mark Webber and Sebastian Vettel will have to undergo changes before the Canadian Grand Prix after an important aerodynamic device that had been on the car since Malaysia was deemed illegal by the FIA.
Red Bull had been running with holes in the step plane of the floor. While other teams have used a similar device, they have been using slots to the edge of the floor; Red Bull’s holes are fully enclosed, and therefore illegal.
In an FIA directive issued to the teams on Friday, Charlie Whiting (FIA technical chief) said:
“It has been argued that, as it is not explicitly stated that fully enclosed holes cannot be located in a surface lying on the step plane rearward of a line 450mm forward of the rear face of the cockpit template, then they may be located in such areas.
“We disagree with this view and consider it implicit that fully enclosed holes may not be located there.”
There had been rumours of a protest after Mark Webber won the Monaco Grand Prix, but the teams preferred a clear resolution in time for Canada on 8-10 June.
