The change of specification was formally permitted at in the present day’s assembly of the F1 Fee, which was held on the F1 organisation’s HQ in London.
An F1/FIA assertion mentioned that “following profitable testing by Pirelli, with the assist of groups, Pirelli have arrived at a moist climate tyre which is rather more performant than the earlier specification – this tyre kind doesn’t require using blankets.”
The brand new spec has been launched following devoted moist climate take a look at periods undertaken by a number of groups over the winter and initially aimed toward 2024, when blankets are set to be banned for each moist and dry tyres.
Moist circumstances and particularly visibility have been a serious speaking level in recent times after a number of controversial races, notably the 2021 Belgian GP.
The F1 Fee additionally confirmed that the brand new moist climate bundle venture – which can see automobiles fitted with wheel arches designed to cut back spray – will probably be examined on monitor in the course of this season.
The FIA has already performed its personal CFD analysis, however the groups now have been given the official go-ahead to do wind tunnel and CFD work on the affect of the arches outdoors of the each the aerodynamic testing restrictions and the associated fee cap.
The assertion famous: “Moreover the FIA is grateful for the presents of assist made by the groups for the moist climate bundle venture, as introduced within the final F1 Fee assembly.

“A technical directive is being ready to permit groups to do such work outdoors the aerodynamic testing restriction (ATR) limits and outdoors the associated fee cap. Monitor testing will probably be deliberate for the second or third quarter of 2023.”
On the finish of final yr new FIA single seater director Nikolas Tombazis gave some perception into the venture.
“We solely suppose it’s going to be one thing that will get used on a few events a yr, possibly three, that form of factor,” he famous.
“We don’t need it to be that each time there’s a drop of rain, then all of the sudden it’s important to match this stuff.
“Now we have completed numerous CFD simulations, as a result of we need to make certain the impact of those gadgets is comparatively small on the general aerodynamics. There nonetheless is an impact, however not a large one.
“Additionally, we’re simulating the droplets of the rain and so forth, and seeing the way it impacts spray. What’s a little bit of a problem within the simulations is to find out the relative proportion of what comes from the diffuser to what comes from the tyres.
“As soon as we now have an answer, we’ll get to do some prototypes and run them on some automobiles to attempt to consider that correctly.”
