Why Mercedes say it is “not price having” a legality row over new entrance wing · RaceFans

Mercedes might revise their new entrance wing design earlier than it’s raced for the primary time on the Mexico Metropolis Grand Prix so as to keep away from a legality row with the FIA.

The crew introduced the brand new wing as a part of a package deal of upgrades for its W13 ultimately weekend’s United States Grand Prix. Nevertheless technical director Mike Elliott mentioned the primary instance was solely delivered to that race for logistical causes and so they “by no means supposed to race” it on the Circuit of the Americas.

“We introduced the entrance wing right here truly simply freight-wise,” he mentioned. “It wasn’t meant to run this weekend, we solely purchased considered one of them so we’ve not bought sufficient.”

The crew intends to run it at this weekend’s Mexico Metropolis race, offering they’ve sufficient elements. “We at all times attempt to ensure not solely have we bought sufficient for every driver, however sufficient that if we now have an off that we’ve bought a alternative,” mentioned Elliott.

The wing attracted consideration as a result of addition of a number of slot hole separators on the prime. The rules state these are permitted “for primarily mechanical, structural or measurement causes”.

Nevertheless Elliott admitted questions had arisen over whether or not they supplied an aerodynamic profit past what was envisaged when the foundations have been written.

“I believe there’s a fuss about it as a result of within the rules it talks concerning the main use being for ‘mechanical’ or ‘measurement’ functions and clearly there’s a secondary good thing about an aerodynamic design that’s in there as nicely,” he mentioned. “We’ll determine whether or not we wish to argue that one or not.”

The FIA first raised considerations over Mercedes’ design after they submitted photos of the wing earlier than bringing a completed instance to the circuit.

“We undergo a CAD [computed aided design] evaluation course of with the FIA earlier than we come to the circuit, that occurs on a regular basis,” mentioned Elliott. “So it was one thing that was seen there after which they got here again and mentioned, ‘we’re not so positive about this’. In order that course of I believe works okay.

“If you happen to have a look at the rules, there’s about 40-odd incidences within the rules of ‘sole objective’. On this case, it doesn’t say ‘sole objective’, it says ‘main objective’. So I believe there’s an argument available. Whether or not we wish to have it’s one other query – it’s most likely not worthwhile.”

He mentioned the slot hole separators solely produce a minor achieve to the wing’s efficiency. “It’s truly not price an enormous quantity. That element appears attention-grabbing however it’s not the large factor on the entrance wing.”

Elliott refused to be drawn on whether or not Mercedes will merely take away among the separators to take away any doubt over the wing’s compliance with the foundations.

“We’ve not determined what we’ll do. The achieve for these bits is so small, is it definitely worth the danger of falling foul of the stewards?

“We at all times undergo and make these selections. However as a result of we weren’t going to run it this weekend, we’ve not spent a whole lot of time occupied with it, we’ll do this within the calmness between the races.”

Requested whether or not rival groups had raised considerations over the design, Elliott mentioned: “To not us, however I’m positive they’ve mentioned one thing to the FIA as a result of that’s the way in which the sport works. In some methods it’s fairly good that they’re speaking about us.”
