Red Bull strengthens front wing after flexing intrigue

The way in which the lower section of Red Bull's front wing appeared to flap down at high speed at Silverstone prompted interest from rival teams, amid fears it could prompt another arms race with regards to flexible bodywork.

It is understood that the FIA had been alerted about the matter by Red Bull's rivals, which may well have prompted a request for modifications to be made.

As Giorgio Piola's exclusive photo shows, the Red Bull appeared in public at the Hungaroring on Thursday with a fastener attached between the endplate and the upper flaps.

This fastener will help prevent the wing flexing down at high speed, and stop any of the behaviour that rivals teams had been looking it.

It is unclear how much performance could have come from the flexing situation, but Red Bull retains high hopes of a step in Budapest thanks to a major update it is bring.

Daniel Ricciardo said that the changes were unlikely to transform the RB13, but it should help deliver improved form on a track that will better suit the car

"Basically it's just big aero updates," said the Australian. "When I say big, does big mean it's a second of lap time? Probably not, but big in terms of different kind of shaping and philosophy to what we've run so far.

"Bits are in different places – there's a bit on the front wing, but then there's a bit with sidepods. It's all aero stuff, but hopefully it all works together and gives us the laptime we desire. It's a combination of things.

"On the windtunnel it looks like it should help downforce and hopefully that gives us the laptime."
