The cost of Red Bull adapting to the FIA’s stricter testing of flexi-wings “will prevent something else from happening” because of the constraints of Formula 1’s budget cap this season.
Tougher load and pullback tests will be implemented from mid-June as the FIA increases its vigilance of anomalous rear wing behaviour.
Mercedes and McLaren have been outspoken at the Monaco Grand Prix this week amid concerns rivals have circumvented rules by finding a way to make their wings pass the existing tests in place then deform under greater loads on-track.
Red Bull is the expected target of that criticism given video footage from the Spanish Grand Prix that showed the rear wing of the RB16B flexing considerably on the straights, although the Alfa Romeo and Alpine cars are also expected to be affected by the stronger tests and Ferrari has revealed it will make a “small change” as well to ensure compliance.
The new tests will be enforced from June’s French Grand Prix, not at this weekend’s race in Monaco or the next round in Azerbaijan, as teams have been given a grace period to strengthen their wings for the revised testing loads.
Red Bull chief Christian Horner admitted his team will have to make changes and said: “For a team like us that’s obviously running up against the [$145m budget] cap then of course strategically you have to make choices.
“The impact of something like this is probably about half a million dollars.
“That will prevent something else from happening.
“But that’s the juggling act that we’re now having to make with a budget cap and financial regs.”
