Jun.16 (GMM/Inautonews.com) Four teams made modifications to their front wing designs ahead of the recent Canadian grand prix.

In the days after Monaco, we reported that the FIA was clamping down once again on the well-trodden area of so-called ‘flexi wings’ in formula one.

Spain’s El Confidencial reported that a new 50 Newton-metre load test would be applied for front wing flexibility by FIA scrutineers in Canada.

Germany’s Auto Motor und Sport now reports that the new test was actually to the tune of 60 Newton-metres, on suspicion that some teams were getting as much as 10 centimetres of aero-efficient flexibility from their front wings.

From Canada, only 3 millimetres of flex would be tolerated during the new load test.

Red Bull, Mercedes, Lotus and Toro Rosso all took new designs to Canada, with the main modification being small ‘supports’ between wing elements.

Correspondent Michael Schmidt said all four teams passed the scrutineering tests.
