System One’s regulator is having a torrid yr because the departure of its president Jean Todt. The incoming premier, Mohammed Ben Sulayem, has grow to be entrance and centre of the FIA’s presence and made numerous adjustments that haven’t been universally welcomed. The choice to maneuver to rotating F1 race administrators has been repeatedly criticised by drivers and the groups for proving to ship an absence of consistency.
Additional following the ‘close to misses’ on the Japanese GP the place a crane was deployed on observe in poor visibility situations whereas the drivers had been nonetheless allowed to journey at speeds of 200kph pressured the FIA to bench race director Eduardo Freitas for the remainder of the season.
Pirelli pressured to alter plans
Now the current Pirelli tyre exams for the 2023 F1 rubber have thrown into disarray the FIA’s long run rules for the ban on tyre blankets that pre-heat the Pirelli rubber previous to them being fitted to the automobiles.
The FIA is set to make System Another ‘inexperienced’ and the proposed ban on pre-heating tyres in 2024 is a part of that vitality effectivity agenda. The temperature to which the tyres had been pre-heated in 2021 was lowered from 100 levels Celsius to 70 levels for this season.
This was regulated to drop ton 50 levels for 2023 and the Austin tyre take a look at in FP2 noticed the groups simulate subsequent years tyres pre-heated to that temperature.
The Pirelli boss, Mario Isola was entrance and centre on the Mexican GP speaking to the assembled media concerning the tyre producer’s present dilemmas.
Tyre take a look at in Austin had good situations
“in Austin, which is a high-energy circuit, we had some points with the warm-up. Or, not less than that they had contemporary in thoughts the warm-up at 70°C and in the event you take a look at the tyre at 50°C, you’ll be able to really feel the distinction.
“After listening to the drivers, we began to think about that if Austin is a high-severity circuit with excellent climate situations they usually had a problem with a warm-up, what occurs at road circuits, low-severity circuits with easy Tarmac, or in poor situations?”
“The goal is to ban blankets for 2024 and the thought was to go on this course step-by-step. The plan continues to be in place, however trying on the take a look at in Austin, evidently 50°C isn’t an acceptable possibility for subsequent yr.”
At present the groups are allowed to begin pre-heating the tyres 3 hours earlier than they’re fitted to the automobiles, but Isola reveals this time span isn’t actually mandatory.
“So we made some calculations of the vitality consumption, contemplating completely different situations as now we have some blankets in Milan that we used for our take a look at. We discovered two hours is the time wanted to heat up the tyre at 70°C, so now we have an extra hour in the mean time that’s simply sustaining the temperature.
FIA problem on rubber change too large
Given the truth that Pirelli needed to cope with a rise in wheel rim dimension from 13 to 18 inches this season along with tyres which might be preheated to a temperature 30% decrease than earlier than, it seems the problem to resign the 2022 rubber to deal with even much less preheating is a step too far.
Isola reveals, “If, as a substitute of happening to 50°C, we reduce one hour [of the currently-permitted three hours at 70°C] we found that it’s much more environment friendly, we save extra vitality and we don’t create any challenge with the warm-up. So the drivers can exit and push, as they’re doing now.
“That’s why we determined in Mexico to check the blankets at 70°C for 2 hours as a substitute of three hours.”
“My feeling is that the appropriate course is to go for 70°C and two hours,” mentioned Isola.
So the regulation limiting the groups to solely warmth the 2023 tyres to 50 levels will probably be rolled again to 70 levels, however the time they will pre-heat the rubber reduce from 3 to 2 hours.
Pirelli towing there FIA get together line for 2024
Isola believes they will nonetheless hit the goal of no pre-heated tyres for 2024, although this now appears unlikely.
“What we collected when it comes to data in Austin is helpful for us for additional growing the compounds.
“We all know now we have to make fairly an enormous step to do away with blankets in 2024. It’s not simply redesigning the development fully, it’s additionally redesigning all of the 5 compounds.
“And now we have now a take a look at plan that we began to debate with the FIA and FOM and shortly with the groups to see whether it is possible. Clearly we have to take a look at on observe and that’s the plan.”
It might be logical for Pirelli to try to first develop their softer compounds to be able to working with out being pre-heated and as Isola clearly says designing 5 compounds for 2024 to run with out tyre blankets is a major problem.
FIA pressured to alter regs for 2023
Williams Racing director of auto efficiency, Dave Robson, backs the decision to retain the pre-heated tyre temperatures at 70 levels for subsequent season. He reveals the vitality saving by decreasing the pre-heating from 3 to 2 hours at 70 levels is slightly higher than the proposed 3 hours at 50 levels.
“So I feel that they discovered course, one thing that hopefully we will take via to subsequent yr.”
“As an intermediate [plan] that in all probability is fairly pragmatic,” mentioned Robson. “Not least as a result of a lot of the element about subsequent yr’s automotive is designed, not essentially set in stone however we’re fairly a great distance down [the line].
“The difficult bit is that the automobiles aren’t actually designed to work with such low grip straight out of the storage. You may’t brake as arduous as you need, the automobiles simply aren’t designed to work like that now.
“Perhaps with a bit extra thought and understanding of what 50°C blankets means for the opening laps of the stint you alter a couple of issues.”
F1 Groups important of Pirelli directions
Pirelli had instructed the groups on the Austin take a look at to go our arduous on the tyres and push from the get go. But Robson observes this might not be the optimum resolution for the brand new decrease pre-heated Pirelli rubber.
“Clearly, as effectively doing these tyre take a look at we simply adopted the run plan Pirelli despatched us, if we had been attempting to get greatest efficiency we could not have accomplished that. They only needed us to exit and push, push, push on the low gasoline and possibly you could be a bit extra tactical about the way you carry the tyres in.
“The automobiles as they stand and attempting to try this run plan, the 50°C blanket is troublesome.”
Given the take a look at rubber compounds had been taking 3-4 laps to heat up can be a recreation changer in System One race technique. Not would the undercut the place a driver pits early to achieve the benefit of contemporary rubber over rivals forward within the race be viable.
This could drive staff strategists to as soon as once more determine observe place is king through the race, a philosophy the brand new aerodynamics of the 2022 automobiles has diminished.
Untimely ban on tyre heaters results in predictable F1 racing
In Mexico for instance the Daniel Ricciardo technique of beginning on the medium tyre and working longer than anybody else, earlier than stopping late within the race for tender tyres when the automotive has burned off 70kg of gasoline would grow to be normative.
In actuality, the tyre blanket warming ban could need to be kicked into the lengthy grass till 2026. Then the FIA are dedicated to rules that see smaller, lighter automobiles with simpler energy items.
The present F1 beasts absolutely laden with gasoline are over 900kg in the beginning of the race. Provided that as much as 110kg of that is gasoline and the FIA are impossible to reintroduce in race refuelling, a savage reduce to F1 automotive dimensions and weight is required earlier than pre-heating tyres turns into a factor of the previous.
