Throughout Method 1 winter testing in Bahrain, the main focus – aside from the continued compression ratio dialogue – has primarily been on vitality administration throughout the races. Reaching constant deployment over longer runs stays a key problem for groups.
Sergio Perez revealed that in his case, there have been nonetheless fluctuations of as much as eight tenths from one lap to a different. Understanding these fluctuations and stabilising deployment is one in all Cadillac’s key aims forward of the second check week, the Mexican defined.
That stated, vitality administration over a single lap can also be difficult as drivers need to deal tactically with each deployment and harvesting. George Russell beforehand defined that the quickest means by means of a nook just isn’t essentially the most effective for the general lap time.
“You have got cases the place once you go across the corners quicker, you are spending extra vitality and also you’re harvesting much less,” stated the Mercedes driver. “So you find yourself over the course of the lap having much less vitality to spend. You might acquire a couple of tenths into corners, however it’s possible you’ll lose a few tenths on the straight.”
Contradictory necessities for tyres and battery
Drivers should optimise this throughout a flying lap, however in keeping with Pirelli there’s extra at play. The Italian tyre provider has discovered from the preliminary working that making ready a qualifying lap is extra advanced below the 2026 rules as properly.
For total efficiency, it’s essential to get the tyres into their working window, however that may conflict with what groups need when it comes to vitality deployment in qualifying.
“To have the tyres prepared for the push lap in qualifying, or a qualifying simulation, they need to run the out-lap at a sure pace,” stated Pirelli motorsport chief Mario Isola. “On circuits which can be low severity, in chilly circumstances, or with a tarmac with low roughness, they need to push somewhat bit to be able to generate warmth into the entrance tyres.

“However with the brand new vehicles, they do not need to use the electrical a part of the facility as a result of they want this for the push lap. So it was somewhat bit difficult for them to know how a lot they may push to have the entrance tyres prepared, and on the identical time all the facility obtainable.”
In apply, this will result in double preparation laps. Final 12 months that was already needed at some circuits, however again then solely to get the tyres into the proper window. This 12 months it’s extra about discovering a stability between two components that may be contradictory at instances.
“It implies that [in testing] some groups have been utilizing the outlap plus a preparation lap, and after that preparation lap the tyres have been prepared for the push lap,” added Isola.
“If in some races this 12 months we see this type of method throughout qualifying, it is in all probability as a result of they need to stability, and to seek out the proper compromise between the warm-up of the entrance tyre and the usage of the vitality that’s obtainable.”
For Pirelli, this was considerably sudden, Isola admitted on the finish of the primary check week in Bahrain. “That is one thing that, I do not need to say we did not plan, however clearly once they run with actual vehicles, we uncover much more in comparison with the mule vehicles,” he stated.
Nonetheless, it’s extra advanced for the groups than for the tyre provider. In accordance with Isola, the findings nonetheless align with the event path Pirelli had already chosen for the 2026 vehicles.

“We have been in search of compounds with a better working vary to be able to minimise the overheating,” added the Italian.
That wider working window is essential, as it may well make issues barely simpler for groups – particularly when it needs to be balanced with the optimum vitality administration preparation.
That may, nonetheless, rely closely on the circuit. Isola noticed double preparation laps extra typically throughout the Barcelona shakedown than in Bahrain, because the latter options significantly tough tarmac and is demanding on tyres. That makes it simpler to generate tyre temperature with out utilizing an excessive amount of of the battery in comparison with many different venues.
At tracks equivalent to Las Vegas – the place the tarmac, structure and chilly circumstances all play a task – the puzzle turns into extra advanced. In concept, the battery could be recharged comparatively shortly in only a few corners, however that requires a reasonably aggressive method and may trigger tyre temperatures to drop. To keep away from these unintended penalties, a extra gradual build-up over two laps could also be seen extra typically.
“I imagine that they begin with full energy, then they should hold the total energy [available] and in a gradual means put the tyres into the proper working vary,” stated Isola.
Which F1 tracks would be the most difficult?
Haas workforce principal Ayao Komatsu underlined this problem and pointed to a number of circuits the place the required tyre and battery preparation might conflict.

“It is a great distance away, however the circuits that come to my thoughts right away, it is locations like Baku or Vegas,” he stated. “On these circuits it is very troublesome to get the tyres to work as properly, after which the outlap. The necessities of getting the battery ready very, very properly, versus [how] to arrange the tyres, it is considerably conflicting.
“You have got this multi-dimensional optimisation difficulty. You have to discover the proper compromise, in order that will likely be difficult, I feel.”
Groups will want all obtainable apply time to refine the optimum method every weekend. Throughout dash weekends, they’ve far much less alternative to take action, which is why Komatsu explains that they may grow to be significantly tougher.
“That is going to be an enormous problem,” he added. “Shanghai, I am not wanting ahead to that. I am unable to say I am wanting ahead to that. One hour of apply to prepare for dash qualifying, that is going to be an enormous problem.
“It is the identical for everybody, nevertheless it’s step-by-step. I feel we’ve had a good preparation up to now, studying issues, however now we have got to compress every thing, refine the procedures, [and look at the] accuracy of every thing to get ready for the conventional race weekend.
“We’ll do one regular race weekend in Melbourne, hopefully it is dry, after which going to Shanghai. That is a dash weekend, so it is a steep studying curve, nevertheless it’s the identical for everybody.”
