Friday apply for the System 1 Bahrain Grand Prix in Malaysia was atypical in a number of respects. Lap instances turned out to be 4 and a half seconds slower than anticipated because of the poor monitor floor, Mercedes didn’t impress as a lot as maybe anticipated and the run plans had been reasonably uncommon.
The latter was maybe most evident with Max Verstappen. Usually, drivers full their qualifying simulations midway by the second apply session earlier than utilizing the second half for lengthy runs. With the FIA estimating the possibility of rain forward of FP2 at 90%, a number of groups needed to play it secure, which in apply meant bringing their lengthy runs ahead.
“I needed to do a future in case there was some rain coming in,” Verstappen clarified when requested about his uncommon Friday run plan.
Pink Bull technical director Pierre Wache additionally defined that the staff no less than needed to collect knowledge on what is taken into account crucial issue of the race weekend at Sepang: tyre degradation.
“We did not need to compromise the long term, which I believe is crucial factor this weekend, when it comes to degradation and see how the tyres behave, particularly the medium. We did not have knowledge of the medium, so we prioritised that and afterwards it was too late to run the gentle,” Wache mentioned.
F1 groups’ greatest problem at Sepang defined
It underlines two issues. Firstly, this quote completely illustrates that taking a look at particular person lap instances after Friday in Kuala Lumpur is pointless. Solely the lengthy runs present a useful image, that means even much less significance needs to be connected to Friday’s classification than common.

Secondly, it underlines that F1 groups’ method in Malaysia differs from a traditional race weekend. Often, it’s a balancing act between qualifying efficiency and preserving the tyres – notably the rear axle – alive through the race, however this time it’s all concerning the latter.
“Now we have seen at the moment that the degradation was fairly important, fairly excessive. I bear in mind only one weekend the place we had this type of degradation and that was Barcelona,” mentioned Pirelli’s chief engineer Simone Berra.
“Now we have recorded round two or three tenths of tyre degradation per lap, on each the medium and the gentle. So the extent of decay is sort of vital right here. Groups must handle particularly the rear temperatures, but in addition the entrance tyres within the high-speed corners.”
Furthermore, that may turn into a vicious circle at Sepang, F1’s tyre provider defined primarily based on Friday’s knowledge.
“As a result of poor floor, the grip was low on each the medium and the gentle. This exacerbated much more thermal degradation as a result of we all know that sliding means greater floor temperatures, greater floor temperatures imply decrease grip, meaning much more sliding, that results in greater floor temperatures once more, and so forth.”
Preserving thermal degradation underneath management is essential to keep away from ending up on this vicious circle, however that’s simpler mentioned than performed. That’s as a result of whereas the rear axle is the first concern and this monitor is ‘rear-limited’, the entrance axle nonetheless requires administration as effectively. And people two issues are troublesome to mix.

“The purpose is that for the rear axle particularly, there isn’t a rear respite right here. It is very troublesome to maintain the temperatures underneath management, you must attempt to keep away from sliding within the high-speed corners and on traction,” Berra defined.
“However in the meantime you must preserve consistency with the tempo and you must keep away from overloading the entrance tyres.
“It is very difficult as a result of you must defend each axles principally, the entrance can overheat and degrade as effectively. It is actually not easy. It will likely be a compromise ultimately, which axle you like to degrade extra. I believe all groups will go to guard the rear, as a result of ultimately, on the rear axle, you lose far more efficiency than on the entrance.”
Extra qualifying query marks: Is a shock on the playing cards?
All of which means the groups’ work and knowledge evaluation on Friday night is totally totally different from every week in the past through the Azerbaijan Grand Prix.
“Baku was a circuit with very low degradation ranges and really excessive significance of qualifying on the entrance rows. Right here, qualifying is much less vital,” Berra continued.
“We all know that it is potential to overhaul, particularly when you’ve this excessive degradation. If you’ll be able to preserve the efficiency and the tyre temperatures within the appropriate window, you possibly can lengthen or you possibly can push greater than different opponents. The place on the grid is much less vital than elsewhere.”

That mentioned, the intense concentrate on race tempo does imply that groups head into qualifying with extra query marks than common, even when it takes place in dry circumstances.
Berra confirms – understandably with out desirous to reveal which groups – that some groups even struggled on Friday to get their tyres as much as temperature for the primary nook of a flying lap. That will sound exceptional given the extraordinarily excessive monitor temperatures, however it’s a consequence of the large concentrate on defending the rear axle and subsequently on race tempo.
An fascinating ultimate level is that there are additionally many query marks for Sunday. As a precaution, all groups have determined to avoid wasting two units of onerous tyres, that means no person – together with Pirelli – has knowledge on the C2, the toughest compound out there this weekend.
Furthermore, given the intense circumstances, the rule of thumb that the more durable the compound, the higher it’s for the race doesn’t essentially apply.
“I’d additionally count on a excessive degree of degradation on the onerous compound, as a result of [a harder tyre] is producing a decrease degree of grip and subsequently a better degree of sliding and better floor temperature,” Berra defined.
“It is one thing that we’ve seen at the moment with the gentle and medium as effectively. Now we have seen in some back-to-back comparisons for the race that the gentle was at an analogous degree of degradation or perhaps a decrease degree of degradation than the medium. That’s as a result of the medium was sliding greater than the gentle and the gentle was extra controllable, let’s name it this manner. And so all choices are open for Sunday.”

The latter is basically excellent news, because it might encourage strategic variation, which is strictly what Pirelli at all times goals for.
“All three compounds are usable as a result of we’re almost certainly going in direction of a two-stop race, and probably even three stops. All the things is, for instance, in play in the meanwhile,” Berra concluded.
“That is producing fairly a giant quantity of prospects when it comes to methods and that is what we wish, additionally from our facet, to generate totally different mixtures.”
