Rinland defends Ferrari over flexi-wing

The Argentinean, who now works as technical director of the Trident GP2 team, said Ferrari's rivals are also using similar systems to improve the performance of their wings - but these are not as visible as the Maranello squad's.

"The commotion around Ferrari's flexing front wing is a bit of a litmus test for F1," Rinland wrote in his column in Autosprint magazine.

"That's because, with the solution of the extra flap on top, the Maranello men put in practice what every other team do, but while Ferrari's solution is visible to the naked eye, their rivals' isn't.

"Everyone works towards making the front wing not only flex, but also give it torsion capability. McLaren, for example, obtain this effect even without the aid of the extra wing Ferrari has. Congratulations to them.

"I've been very surprised by Renault's rear wing, with its ability to flex along the vertical axis. But the FIA, who introduced a long series of checks on wings flexibility, in this case verifies the deflection only along the horizontal axis. I'm surprised no one has copied the R26 yet."

The FIA said on Monday there were concerns regarding several teams but they would be rectified before the next race.
