Nevertheless it has not been totally clean crusing within the 18 months because the new ground-effect automobiles emerged, with grand prix racing having endured its share of ups and downs.

On the Positive aspect, the automobiles do appear higher in a position to comply with one another than the older technology of equipment, which has allowed for some nearer battles than we might have in any other case anticipated.

Nonetheless, there have been some complications too, particularly when it got here to F1 groups and the rule makers battling the extreme porpoising that blighted the early operating with the brand new automobiles.

It says a lot in regards to the positives of the brand new guidelines set, nevertheless, that, as feeder series F2 looked to deliver its next-generation car for 2024, it has taken on board most of the classes realized from F1.

Quite than electing to stay to a easy evolution of its present tried and examined design method, its 2024 guidelines set very a lot strikes it extra in the direction of F1’s present technology – with floor impact, comparable wing ideas (excluding the eye-catching DRS component) and like-for-like security requirements.

And it’s all geared toward one factor: producing a automobile that may race nicely.

As F2’s technical director, Didier Perrin mentioned: “With the aerodynamics of the automobile, we targeted on the power to overhaul: so the chance for a automobile to comply with one other one.”

Tim Goss, the FIA’s technical director who works throughout all classes, is obvious that the Positive classes taken on board from F1 because the begin of 2022 have been decisive in shaping the route of the F2 challenger.

Requested by Autosport in regards to the switch between F1 and F2, Goss mentioned: “The 2022 F1 automobile did make a major step ahead by way of how intently the automobiles may comply with via corners.

“That was via a variety of consideration to element on two issues: the form of the wake that is generated from the again of the F1 automobile, but additionally how the entrance of the F1 automobile offers with disturbed movement.

“What we took as a place to begin for the F2 automobile was the FIA had developed an F1 baseline, the precise code identify of the automobile was Uniform. And we morphed that right into a Components 2-sized automobile with F2-sized tyres, and so on.

Learn Additionally:

“Then what we needed to do was, as we could not simply take that because the automobile to take ahead, we needed to respect the efficiency figures that we had been aiming for in F2, and likewise the truth that we have now to take complexity out of the automobile and attempt to maintain the fee down.”

That DRS rear wing

It has not simply been a easy copy-and-paste train although, and the FIA and F2 have elected to take some additional steps to make sure the automobile continues to assist produce good racing.

Nothing exhibits that greater than the eye-catching rear wing, which options an enormous fan-shaped fundamental beam DRS component that can set off an enormous velocity delta when it’s used.

Goss explains that the design was triggered by a need to verify DRS was very efficient.

“What we had been on the lookout for was a given measurement of DRS delta, so you could just be sure you’ve received sufficient authority,” he mentioned.

“It is easy to show DRS down. You are able to do that with zone lengths, and variety of zones, issues like that, however you actually simply must just be sure you have sufficient authority.

“To be trustworthy, one of many greatest challenges with the rear of the automobile and the rear wing was placing an F1 type rear wing on with the rolled edges, that are good for the wake efficiency, while being conscious of the fee and ease in the true phrase.

“So what Dallara have give you, I feel, is a improbable answer by way of delivering the required wake efficiency, nice aesthetics, and one thing that delivers the DRS.”

Porpoising hazard

The transfer in the direction of a floor impact automobile has inevitably raised the prospect of F2 affected by the identical porpoising destiny that has overshadowed F1 to a higher or lesser extent for the previous 18 months.

However Goss is adamant that, whereas everybody on the grand prix grid was taken without warning in regards to the extent of the bouncing at the beginning of 2022, the information of the elements at play now’s serving to groups keep away from it.

These exact same classes are being utilized to the F2 automobile, which is why he thinks the sequence can keep away from falling into the identical lure F1 did.

“We had been very aware of that once we received into the specification of this automobile as a result of simply on the time we had been laying out the necessities of the automobile with the promoter, F1 was in hassle with experiencing fairly important porpoising on the automobiles.

“We clearly knew an affordable quantity about it ourselves and, in figuring out the specification of the automobile and what we wished to realize in enhancing automobile following, we additionally wished to guarantee that, while we’re transferring to extra floor results, we weren’t overdriving the ground and we weren’t placing too many calls for on the ground.

“It was actually fairly necessary to us that by way of the aerodynamics of the automobile, that the answer was one which generated downforce with the automobile at larger trip heights, and that there wasn’t the necessity to drive the set-up ever decrease and get into porpoising issues.”

And whereas proof of how nicely the F2 automobile has averted porpoising will solely be identified when correct efficiency observe testing begins later this month, sequence chiefs are optimistic about it.

Perrin added: “We clearly don’t count on any porpoising as a result of we labored alongside the FIA for the definition of the automobile. We took the advantage of the expertise of the FIA and F1.

“We’ll verify it, and clearly it will likely be one of many first issues that we are going to verify, that we’re not affected by porpoising. We’re assured that it’s going to not occur.”

The brand new-generation F2 automobile is a good instance of classes in a single class being utilized to a different, and the Positive trickle-down impact that F1 information can have in different sequence.

However issues won’t cease there. The FIA hopes the teachings about what is required to provide good ‘racing’ automobiles can comply with via into the brand new F3 automobile that’s coming for 2025.

As Goss mentioned: “What we’re making an attempt to do is take all the teachings realized from F1 and F2, to supply nice racing. That’s the goal: to attempt to make nice racing. And that goes past simply having overtakes with DRS on straights, so we are going to carry that ahead into F3.”
