Ferrari just lately helped the FIA with the evaluation of a more complete wheel guard concept during runs at Fiorano to see if it might assist scale back spray.

The design was rather more dramatic than the unique thought tried out at Silverstone final yr, and Ferrari ran two vehicles shut collectively to guage if it introduced any enchancment.

The newest covers have been intentionally excessive as a result of the FIA needed to raised perceive how a lot of an enchancment visibility can be if there was no spray thrown up by the wheels.

The conclusion after the check, primarily based on video evaluation, was the profit was marginal – as there stays an incredible quantity of water thrown up by the diffuser.

The conclusion from the FIA was fast that the wheel cowl thought is now not price pursuing, so different choices to attempt to assist in treacherous situations at the moment are being evaluated.

Talking solely to Autosport, the FIA’s head of single-seater issues Nikolas Tombazis stated the wheel cowl mission was now stopped because it was not going to ship the step-change hoped for.

“We at all times knew that there have been two major contributing elements to the cloud of spray,” he stated. “One was how a lot water is picked up from the bottom from the diffuser, and the opposite one is from the wheels.

“What we thought we might do is attempt to do a complete wheel cowl, even past what can be sensible, to see what’s the most we are able to probably obtain with that – to be able to see whether or not that’s the answer or not.

“The earlier wheel cowl check [at Silverstone last year] was means, means too flimsy and too small. And subsequently I do not suppose it was ever going to work.

“So we went to the utmost simply to see what was the perfect we might obtain from the wheel covers. And whereas they do have a little bit of an impact, they do not have a big sufficient impact to say that that is the answer. Due to this fact we’re again to sq. one.

“Let’s say that I feel we have answered just a few questions. We all know the place we’re, however I do not suppose that is persevering with as a mission in the intervening time, as such. Now we all know we have to discover different methods to guard races from being cancelled.”

The affect of the venturi ground in throwing up a big quantity of water has prompted earlier concepts about including one thing to the diffuser to assist maintain the water down on this space.

Nonetheless, Tombazis is sceptical about this concept, as he thinks something performed on this space would have a big adverse impression on downforce era.

“Theoretically you might do one thing there, however that will be like eradicating all of the downforce and so forth. So it will be fairly a problem. It isn’t a straightforward subsequent step, to be trustworthy. We’ve got to debate it,” he stated.

“However essentially, as a check, it [the Ferrari design] labored as a result of it confirmed us what we have been searching for. Generally checks go nicely and also you say ‘implausible’, and typically they go the opposite means and inform you the course you might be following shouldn’t be good and you have to observe one thing else. That one thing else must be established now.”

Tombazis stated he had just a few concepts about what might be performed, however didn’t need to go public with them but.

However he stated the hope was that, regardless of the reply was, it might assistance on the uncommon events when situations have been particularly excessive.

Learn Additionally:

“We have to consider completely different options,” he defined. “Finally, what we need to keep away from is a Spa 2021 state of affairs the place a race will get cancelled, or severely shortened, or severely delayed.

“Clearly, it is at all times going to be a compromise. The wheel covers themselves have been fairly ugly, but when that they had performed a big contribution, then we might have been completely comfortable to put in them every year if that makes a distinction between cancelling a race or not.

“It was by no means supposed to be ‘each time it is moist we put them on’. However sadly, we do have to attempt to consider different options.”
