The race was an ideal storm of excessive ambient temperatures, humidity that ramped up on race day, draining heavy g-loadings by way of the quick corners, and the one-off tyre guidelines that turned the race right into a sequence of 4 sprints, with little respite for the drivers.

The FIA quickly promised an investigation into the components concerned, and that has shortly developed into the topic being added to the subsequent assembly of F1’s technical advisory committee, the place groups and the governing physique focus on rule adjustments. 

F1 CEO Stefano Domenicali has additionally written to the GPDA (Grand Prix Drivers Affiliation), basically thanking their drivers for his or her efforts, and acknowledging how robust their Sunday night was.

He additionally identified that scheduling the Qatar race for early October was unavoidable, and reminded them that subsequent 12 months it’s going to transfer to December, and thus situations received’t be so difficult.

The date change ought to definitely take the sting off the particular points seen in Qatar, and a few imagine that must be the top of the matter.

Nevertheless, the race highlighted an even bigger image of unregulated cockpit warmth, and the position performed by hitherto little-known components comparable to thicker overalls mandated since Romain Grosjean’s accident on the 2020 Bahrain GP.

The topic has undoubtedly received the eye of the drivers, and it goes far past the particular circumstances of Qatar, because it’s probably that there might be different races sooner or later the place warmth is a matter.

GPDA chairman Alex Wurz is in shut contact with each the FIA and F1, and he’ll make sure that the problem stays on the game’s agenda, and that classes are realized for the long run.

“The underside line is we, that means the game, will cope with it,” he says. “And I’m sure the fitting stability might be discovered.”

One other ingredient to the story is the suggestion, even from former F1 drivers, that the Qatar race by some means highlighted that the present stars will not be match sufficient, or contrasting what occurred with different racing classes and even with different sports activities. As you’ll be able to think about that hasn’t gone down nicely.

“What I can say is I prepare considerably for the warmth,” says GPDA director George Russell. “I prepare with three layers of garments forward of those sizzling races. I do an enormous quantity of saunas to adapt to the warmth.

“These guys who’re commenting on this, we’re driving laps 20 seconds quicker than they have been, going by way of corners pulling 5G in each single side. And naturally, we must be gladiators.

“However relating to the warmth, there’s solely a lot the physique can take. And when you take the distinction of the Qatar World Cup, as a result of warmth they added three-minute water breaks twice all through the sport.

“They’ve their 15-minute half time break, and we have been driving flat out for 90 minutes on a brilliant high-speed circuit, a excessive downforce circuit, with temperature and humidity that have been by way of the roof.”

He paints a compelling image of how robust it was: “Anyone can say what they like, but additionally the race automobiles within the nineties and eighties, they did not have all of the digital bins across the cockpit heating the cockpit up.

“They did not have the facility steering system that was operating at 50-60C radiating warmth. We have now hydraulic strains operating throughout the cockpit, which is at 120C. The cockpit was closing in on 60C all through that race.”

He added: “I do know from some drivers who suffered with heatstroke, they have been sick for the week following.”

Wurz is adamant that it’s flawed to narrate what occurred in Qatar to driver health, as situations have been so excessive. He believes that the time has come for the FIA to manage the matter.

“Warmth fatigue shouldn’t be essentially immediately linked to health,” he says. “So it is not sufficient for individuals to say these guys must be fitter. As a result of health, once more, shouldn’t be all the time associated to warmth resistance.

“There’s plenty of contributing components to warmth fatigue and dealing in a sizzling setting. I do imagine that the aggressive nature of all these contributing components made it a unprecedented occasion in Doha, one thing we have to be taught from, and progress.

“And that is undoubtedly to not make the game that you must be much less match. No, it is simply that there is sure guidelines and limits. Like with all the pieces, each performing half on a race automotive has a restrict. The FIA offers load limits, temperature limits, weight limits, deflection limits.

“And the motive force is a type of 100 performing components. And there also needs to make certain limits. We have now limits once we hit the wall of when now we have to go to the medical centre. Different sports activities have warmth associated limits. Supplies have warmth associated limits.

“Nobody asks to make the game much less arduous, much less robust, straightforward. It would by no means be straightforward. I feel that might be a extremely inappropriate remark from anybody. So backside line is we have to simply look into the contributing components, be taught from it, and transfer on with it.”

One of many fundamental issues is that present automobiles are by the character extremely sizzling, with a lot package associated to the facility unit in shut proximity to the drivers as groups squeeze the boundaries of packaging.

“The hydraulics, electronics, all of them run extremely popular,” says Wurz. “The entire package deal is nearer than ever earlier than, and this can be a typical impact of racing and F1. And even perhaps the aerodynamics with the halo and the brand new downforce means there may be much less cockpit air flow, and fewer air going out.

“Motorsport itself has sure classes with warmth associated guidelines. Within the World Endurance Championship, the cockpit temperature has to have a sure restrict above ambient temperature that’s measured.

“After which the mitigation is all the way down to the groups, and the groups after all, do this. So this can be a regulation mainly forcing the groups to assemble the automobiles in a method that the working setting is ready to a restrict.

“Within the WEC now we have aided cockpit temperature, but additionally groups run with cooling seats. It is one thing we run simply to make sure the efficiency of the drivers shouldn’t be in any form restricted by the warmth, in order that they’ll go flat out and exhaust themselves with simply pushing and never warmth exhaustion, as a result of it’s two various things.”

Cooling seats have develop into a subject of dialog in F1 circles, and Wurz can draw on private expertise of how precious they are often.

There’s clearly a weight issue with any such tools, as there may be with easy issues like drink bottles that F1 groups have typically not used for simply that purpose, however the features from having a match and wholesome driver could be important.

“I did one IMSA race with Chip Ganassi within the States,” says the Austrian. “This automotive was so sizzling that with out the cooling seat after 40 minutes, you have been finished, like correctly finished and grilled. And with the cooling seat, it was okay and simple to do three stints, so two and a half hours within the automotive.

“The automotive did not have a lot downforce, however the warmth was so sturdy, and the cooling seat already provided sufficient cooling and circulation that that you simply have been underneath management, and your working setting was mainly nonetheless having to cope with the health and forces and focus.

“That after all was a efficiency associated factor the groups did, as a result of they knew all the pieces within the automotive was too sizzling to mainly run for applicable stint lengths.”

Fernando Alonso additionally has latest expertise of sportscars after his spell with Toyota.

“In WEC there’s a sensor within the cockpit, and the temperature inside can’t be two levels greater than the skin temperature,” says the Spaniard. “If you’re above that temperature, you must cease, the FIA tells you to cease.

“There may be some sort of air conditioning. And I feel there was work behind these rules to verify that there have been not electrical bins within the cockpit, and issues like that, simply to just be sure you are throughout the rules on the temperature.

“I feel the precedence in F1 is simply to place the all of the bins and all this stuff within the cockpit, as a result of you’ll be able to tighten the bodywork, and also you make precedence for aerodynamics, which is clearly good.”

In Qatar, Alonso suffered with a selected cockpit sizzling spot that had arisen beforehand with the AMR23, however which tipped over the restrict. The crew is already engaged on enhancements.

As famous one other situation that has emerged is how the thicker overalls mandated since Grosjean’s accident have made life tougher for the drivers.

“The racing package, the overalls, the fireproofs beneath, may be very thick proper now, to be throughout the rules after Grosjean’s crash,” says Alonso. “So it’s a tough matter, as a result of it’s essential have very secure tools for fireplace in case it occurs.

“However that tools is in some situations, in some races, is simply not evaporating the warmth, it simply stays with you for the entire race. So the physique can not carry out at its regular stage.

“The rules are simply a lot harder for the businesses to go the fireplace check, and now they’re thicker. However as I stated, they’re safer. So you realize, that is the place you place the fitting stability.”

Russell added: “The fireproofs are considerably thicker. It is like carrying a fleece.”

Alonso flags one other situation that he sees as a contributing issue and is nothing to do with the automobiles, however slightly the build-up to races.

“We try to do our greatest by way of preparation as nicely, attempting to begin the race as cool as potential,” he says. “Simply concerning the temperature, for certain, we are going to focus on with FIA a few totally different situations and procedures.

“I am not a giant fan for instance of the nationwide anthem being 14 minutes earlier than going within the automotive. I feel that is unthinkable in some other sport, that you’ll put your physique within the restrict.

“So if that may transfer a little bit bit earlier, after which you’ll be able to quiet down earlier than going within the automotive or no matter. It’s simply placing that temperature restrict additional into the race, as a substitute of reaching that restrict in lap 15, perhaps you attain it in lap 40, and it’s solely 15 laps of struggling.”

Whether or not any answer is focussed on driver tools, or adjustments to the automobiles, stays to be seen.

“Ought to it solely be the groups taking a look at it from a efficiency perspective?,” says Wurz. “Or does it want a warmth associated rule like soccer or triathlon has temperature associated guidelines? We’ll debate between the stakeholders.”
