Formula 1 teams will face tougher tests later this season limiting how far their rear wings may flex.
Lewis Hamilton drew attention to the “bendy” rear wing being used by rivals Red Bull following qualifying for the Spanish Grand Prix last weekend. Red Bull team principal Christian Horner said “the FIA are completely happy with the car” when asked about Hamilton’s comments.
However F1 teams have been notified this week of a new technical directive, TD 18/21, aimed at preventing rear wings from rotating backwards at speed. This will be done by subjecting the wings to tougher static load tests. The loads they are subjected to in the ‘pull-back’ and ‘push-down’ tests will be doubled.
Formula 1’s technical regulations permit the FIA to introduce the tougher tests mid-season. The directive will come into force next month, ahead of the French Grand Prix. The date has been chosen in order to give teams several weeks to revise their designs and produce new components if necessary.
Teams will therefore be permitted to continue using their current designs at the upcoming races in Monaco, Azerbaijan and Turkey.
Horner said he was “surprised” by Hamilton’s comments about his team’s wings and indicated he believed Mercedes CEO Toto Wolff was behind them.
