Once-dominant Formula One champions Red Bull are considering their technical options after failing to make the podium for the second race out of three so far this season.
Team principal Christian Horner told reporters after the weekend's Chinese Grand Prix that they could go down a similar route to Mercedes whose controversial rear wing has been declared legal.
Mercedes' German driver Nico Rosberg took a crushing first grand prix win, and a first for a works Mercedes team since 1955, in Shanghai after securing a first pole position by a hefty margin.
"I think there's been a lot said and a lot of fuss about it (the wing)," Horner said. "They've optimised and capitalised on it so inevitably now we'll all pursue our own solutions."
'Personal ambition' fulfilled for brawn
Shanghai: Of the many Formula One victories that Ross Brawn has celebrated over an extraordinary career spanning several decades, Nico Rosberg's first with Mercedes in China offered a particular satisfaction.
The burly, bespectacled Briton, who followed Michael Schumacher from Benetton to Ferrari as technical director and then won a title with his own Brawn team in 2009 before it became Mercedes, was barely a toddler when Mercedes last won a grand prix as a works team. "As someone reminded me, I was one year old when we last won a race," the 57-year-old said after Sunday's triumph.
"So it is a very special victory and made all the sweeter because it is Nico's first. And I am really delighted, because I told him once that it was my ambition to help him win his first race."
