SPA, Belgium — Red Bull will revert to its previous specification of rear wing for this weekend’s Formula 1 race in Belgium after Max Verstappen’s recent incidents in Austria and Great Britain.Verstappen crashed out in qualifying for the Austrian Grand Prix three weeks ago when part of his rear wing failed, going off at the high-speed penultimate corner of the Red Bull Ring.Eight days later, the four-time world champion spun off-track at Stowe, another high-speed corner, during the race at Silverstone, costing him a podium finish.Verstappen said afterwards that the incidents had been “super dangerous” and that he was feeling “really fed up” with Red Bull’s recent issues.Red Bull adopted an unconventional rear wing design from the Miami Grand Prix, following Ferrari by introducing a so-called ‘flip-flop’ or ‘macarena’ wing where the main plane of the wing flips over 180 degrees when opening in Straight Mode. It is estimated to offer a top speed advantage than the more conventional rear wing designs used by the rest of the grid, which open by simply flipping upwards to flatten the top plane.In light of the crashes, the team will now revert to its older specification of rear wing for both Verstappen and teammate Isack Hadjar’s cars for this weekend’s Belgian Grand Prix.The Spa circuit features a number of high-speed corners, including Eau Rouge, Raidillon and Pouhon, where any issues causing a loss of downforce from the wing could lead to accidents.Red Bull will continue to refine the design of the ‘flip-flop’ wing in the hope of bringing it back to the track at future race. Team principal Laurent Mekies said after Verstappen’s spin at Silverstone that although the issues in the two incidents were not exactly the same, they were both related to the rear wing.Verstappen said in Thursday’s FIA news conference it was “quite obvious” why the team was returning to the previous wing design.“We’ll go back on the old one, and see whenever the latest or new one is ready again to be used for us,” he added.Verstappen is seventh in the drivers’ championship (John Thys /AFP via Getty Images)In the wake of Verstappen’s crash at Silverstone, the FIA’s technical department made enquiries with Red Bull about the design and operation of its rear wing.F1’s governing body, which takes a keen interest in any safety matters, also spoke to Ferrari about its own rear wing functionality.But the way in which Ferrari’s design operates is different to Red Bull’s. While Ferrari’s opens using actuators on either side of the rear wing, Red Bull uses a single central actuator in the middle of the wing. The Red Bull design also creates a bigger open gap — intended to offer a greater top speed boost — when the wing is open.Ferrari also has not encountered any issues with its ‘flip-flop’ rear wing. It started testing the concept towards the end of last year when designing the SF-26 car and debuted it at preseason testing — at which point it also discussed the design with the FIA — before refining its operation ahead of it being used in qualifying and race sessions from Miami onwards.Hadjar felt the return to the previous rear wing design would have a bigger visual impact than on the car’s performance, saying it is “hard even for us to measure the loss going back to it.”“We still reckon to have similar competitiveness to last weekend, for example, even though it’s definitely a less impressive rear wing,” Hadjar told reporters. “We’re making sure the other one comes back to us as soon as we can, and in a safer way as well.”Hadjar added that he got “quite lucky for two rounds in a row” not encountering any issues with the wing. “It could have happened to none of us, and it could have happened four times to the both of us,” Hadjar said. “On this one, (Verstappen) took it for me unfortunately. It’s his problem, it’s my problem as well, and we need to fix it.”Verstappen said after his retirement at Silverstone that it would take “a very zen person to be optimistic at the moment” given the reliability issues he’d encountered. The retirement at Silverstone left him a lowly seventh in the world championship with just two podium finishes to his name this season.“We’re just looking to the future, trying to fix current issues that we have on the car,” Verstappen said on Thursday at Spa. “But that’s a very open discussion.“Yes, sometimes you get a little bit disappointed or upset after a race. For example, after Silverstone, you go home, you reset. On Wednesday, I was back at the factory, and then you prepare again for the weekends ahead.“That’s how I’ve been operating all the years together. Of course, some years you’re just a little bit more competitive than others. But in terms of my approach and how we work as a team, nothing really changes.”
