The Williams team will run an updated version of its F-duct in this weekend's European Grand Prix.
Williams first ran the blown rear wing in the Chinese Grand Prix in April, but the team has not used it since the Spanish Grand Prix last month. Now the British squad will bring it back for the Valencia race this weekend, but as yet it's unclear if the F-duct will be raced or not.
Williams will also introduce further upgrades on the FW32 in the hope of taking a step forward following a difficult season so far.
