F1 clamps down on versatile rear wings

Formula 1’s governing physique has launched a clampdown on versatile rear wings amid suspicions groups are bending the foundations.

The governing physique has written to groups saying it had “become aware” some rear wings handed checks however had “excessive deflections while cars are in motion”.

The FIA has informed groups it is going to introduce new load-deflection checks from 15 June.

In addition to new, extra focused static checks, the FIA plans to make use of on-board cameras to watch the behaviour of wings whereas automobiles are in movement in an try to identify any extreme motion of bodywork.

Teams might be required to place a collection of markings on their wings to facilitate this course of.

Article 3.eight of the F1 technical rules states that bodywork have to be “rigidly secured to the entirely sprung part of the car” and “remain immobile in relation to the sprung part of the car”.

This is a ban on so-called ‘moveable aerodynamic units’, which has been in place for a few years.

But it’s a troublesome space of the foundations as a result of all surfaces flex below load to a point, and traditionally some groups have tried to take advantage of this searching for an aerodynamic benefit.

If a wing or different bodywork half may be made to deflect or rotate in relation to others above a sure pace, it might probably cut back drag on the straights and make the automotive quicker. The bodywork would then snap again into optimum downforce-producing place earlier than the corners.

FIA single-seater technical head Nikolas Tombazis wrote in a notice to groups that the deformations the FIA was referring to “can have a significant influence on a car’s aerodynamic performance and hence could be deemed to contravene the provisions of article 3.8”.

He didn’t title groups or give particular examples of wing behaviour.

“We will be looking out for any anomalous behaviour of the deformation of the rear wing,” stated Tombazis.

“In particular, we will not tolerate any persistent out-of-plane deformation that may be contrived to circumvent the symmetrical loading applied in the load deflection tests.

“Should we observe any traits that point out exploitation of this space, we are going to introduce additional load deflection checks as crucial.”

Teams are being given a month to comply with the new tests so they have enough time to strengthen their wings if necessary.

There will be a tolerance of 20% built into the test in the first month of its operation.

Red Bull team principal Christian Horner said at the Spanish Grand Prix that Toto Wolff, his opposite number at Mercedes, had spoken to him on the issue.

Horner insisted his car complied with the regulations, saying: “The automotive’s scrutineered totally and there are pull-back checks, every kind of checks it has to move,” he said. “The FIA are fully completely happy it has handed all of the checks which might be fairly stringent.

“I was surprised to see his comments, but it is something Toto has mentioned to me previously. So I doubt it was Lewis’ opinion. It probably came from elsewhere.”

The first race at which the brand new checks will come into pressure is the French Grand Prix on 25-27 June.

Before then, F1 is scheduled to race in Monaco on 20-23 May, Azerbaijan on 4-6 June and Turkey on 11-13 June, though the Istanbul race is unsure following a surge in coronavirus instances within the nation.
