Red Bull expects to have mechanical fixes for its Macarena rear wing in play in time for it to return at next weekend’s Hungarian Grand Prix.

Following the crashes suffered by Max Verstappen at the British GP and in qualifying in Austria that were linked to problems with the squad’s trick rear wing, Red Bull elected to remove it for this weekend’s event in Belgium.

This also followed intervention by the FIA, which sought assurances from Red Bull and Ferrari that there were no wider safety concerns with their upside-down wings.

Speaking at Spa-Francorchamps on Friday, Red Bull technical director Pierre Wache said that the issues had been traced back to a mechanical problem with its wing design.

Work was now ongoing at its Milton Keynes factory to implement solutions that would ensure no repeat trouble in the future, with hopes high that the revamped design would be ready for next weekend’s race at the Hungaroring.

“It's a mechanical problem that we spotted after the accident in Silverstone,” said Wache.

“We fix it. We are trying to prove that we are bulletproof before we put on the car, and it should be ready for Budapest.”

Wache was clear that Red Bull would not bring the wing back until it was convinced that it would be problem-free, although he did not elaborate on the specifics of what had caused the issues at the Red Bull Ring and Silverstone.

However, he said some elements of the wing – most likely related to the activation mechanism – were being made “stronger” and that its discussions with the FIA had left the governing body happy with what it was planning to do.

“We’ve proved it to them, what we've done,” added Wache. “I think it's on our side that we make it cautious now. We don't want to take any risk, and we want to be 100% sure.”

Ferrari: no problems in 10,000km

While Red Bull chose to remove its Macarena wing for Belgium, Ferrari has continued with its design, which has not caused it any trouble this year.

While there were talks with the FIA that wanted to check on the robustness of its concept, Ferrari team principal Fred Vasseur insisted his squad has never had any doubts over what it is doing – especially because its design works in a slightly different way to Red Bull’s.

“It's not a similar concept, because it's not rotating in the same way,” he said. “We didn't have any issue.

“We were a bit slow at the beginning [to get it to work]. It's why we didn't race the wing in the first two or three events. And we raced it after race four.

“So far we did 10,000km without any issue.”
