Forward of grand prix qualifying at each Method 1 race, the mechanics throughout the grid should full a job they simply can’t get unsuitable.
That is to strip two automobiles down after every FP3 session or dash race and construct them again up once more, whereas incorporating the ultimate set-up changes and repairs required by their drivers and engineers.
On a typical non-sprint weekend, the entire course of have to be accomplished in simply 150 minutes.
“It’s one of the crucial necessary issues we do,” Matt Thompson, primary mechanic for Nico Hulkenberg at Haas tells Autosport.
“It is the final time you may really work on a automotive. As soon as the automotive is in parc ferme, you may’t contact it, you may’t change something…”
On the latest Mexican Grand Prix, we noticed precisely how this course of is performed at Haas, in addition to studying simply how fraught it may be if the sudden rears.
The countdown clock tells all

We arrive at the back of the Haas storage simply in time for FP3 to conclude in Mexico Metropolis.
Lingering ideas from the story we’ve simply been submitting on the information of the weekend – F1 driving requirements within the wake of Max Verstappen’s cynical ways deployed once more at Austin the week earlier than – must wait. There’s lots to hear into on the Haas communications channels.
Neither VF-24 is within the storage at this stage – their nonetheless out on observe on the Autodromo Hermanos Rodriguez within the fingers of Nico Hulkenberg and Kevin Magnussen.
However the chequered flag has simply fallen and as they return to the pits the order for “double cease” apply is issued by Haas group supervisor Peter Crolla, sat apart group principal Ayao Komatsu on the pitwall far in entrance of our vantage level.
Hulkenberg will get again first and is serviced with a speedy tyre swap earlier than being pushed out of the best way so Magnussen also can obtain the therapy. Crolla and Komatsu forged intense eyes on proceedings.
The 2 automobiles are then shortly wheeled and again in “wheels and bodywork off” directions are issued by Elliot Parkes, the primary mechanic for automotive 20 (Magnussen), and Thompson for automotive 27 (Hulkenberg). A further name for a “T-Tray check right this moment if doable” from Thompson pricks our ears given the furore over this half at Purple Bull the earlier week in Texas.

“Nevertheless it’s a routine factor that we all the time must do,” he later explains. “You all the time have to verify the automotive’s authorized.”
Instruments grasped, our bodies slung over and beneath these multi-million-pound machines – the Haas crew is ablur in motion.
Eight minutes into the enshrined timeframe for his or her most necessary work of the weekend and Magnussen’s automotive up is on its stand. Three minutes later, the engine cowl beneath Hulkenberg’s quantity 27 sticker is eliminated, with Magnussen’s shortly afterwards. Nevertheless it takes till 12 minutes post-FP3 for Hulkenberg’s automotive to hitch its sister in being raised up off the bottom.
A countdown clock on the storage lining screens declares: “lunch snacks 12.45”. That is simply to let the mechanics know they’ll get one thing to eat over the occasion’s lunch break – a sedate affair for mainly everybody in F1 besides these motley bands at every group – in paddock hospitality after they get an opportunity.
With the bodywork off every automotive, chunky yellow padding is positioned alongside the sidepod-lining radiators. That is to “defend us from the warmth, but in addition protects us from damaging the radiators as effectively”, explains Thompson.
“Think about if you happen to simply dropped one instrument on it,” he provides. “You then’ve acquired a leak earlier than you already know it and one other large job to do in that two-hour interval.”
Not fairly quarter-hour into this vital interval and the large drum coverings are off the brakes on Magnussen’s automotive, their orange sponge coating inside revealed. Shortly after, with but extra engine cowl panelling stripped from each automobiles, Magnussen’s crew is advised by Parkes that “as soon as the t-tray check is completed we’ll drop right down to examine the ground as there’s a few bits I might wish to make good from final evening”.
Parkes and Thompson are working by way of their checklists by way of a devoted chatroom on their computer systems. This has colour-coded directions for what has been ordered from the Haas engineers by way of set-up changes, in addition to the everyday checks, alternative work and repairs, and to point out what of this has been accomplished or not.
On the 27-minute mark post-FP3 – the plank off is faraway from Magnussen’s automotive. A meaty, smoky odor abounds – the results of this half being scrapped at as much as 217mph across the Mexican observe.
“We all the time take it off to measure it and examine, as a result of we are able to work out skid wears and stuff like that from there,” Thompson explains. “After which, clearly, we match model new stuff for qualifying to provide us the most effective likelihood of our calculations being authorized on the finish of the race.”
Arriving at 30 minutes post-FP3 and ground and diffuser have come off automotive 20, however notably not the 27. Magnussen’s ground is carried out the again of storage by two mechanics – a darkish chalk outline-like silhouette that betrays the immense scale of those fashionable machines like no different.
Right here, Hulkenberg’s automotive fires up. Its wheels rotate slowly on its stand as methods are analysed for faults by engineers, a beast virtually pawing the bottom, whereas a hose pulls the fumes away from the mechanics. However Magnussen’s received’t do the identical for practically an hour.
“Usually, it is scheduled to be on the similar time,” says Haas chief mechanic, Toby Brown. “However whoever’s prepared first, you simply get on and do it. You might need one thing else to do later.”
With Hulkenberg’s automotive silent once more, a staffer from Method One Administration arrives to examine the rear digicam on automotive 20. He does his work on the system inside as soon as the duvet has been eliminated for him.
Nearing 40 minutes post-FP3 and there’s a lot adjustment to automotive 27’s entrance wing happening at entrance of the storage, beneath supervision from Hulkenberg’s engineer, Gary Gannon.

He explains the “actually fraught” legality checks that have to be executed on the set-up changes which have are available in for qualifying. That is after the post-FP3 debrief that has occurred between the drivers and engineers behind the storage within the large tents that additionally double as group hospitality models for this race.
Right here, Gannon is particularly ensuring those utilized to the entrance wing match within the containers FIA scanners will later invisibly undertaking and check post-qualifying, so the group is not caught out as Williams was with Alex Albon’s ground discovered to be too large again at Zandvoort. Some margin have to be left on each adjustment, however doing so means risking lacking efficiency.
Gannon says this may typically come right down to a 0.01mm adjustment.
We’re simply noticing how calm the whole lot is – little wasted chatter – when a Paddock Membership tour is introduced in. Much more gawping ensues.
Then, because the one-hour-mark post-FP3 approaches, Magnussen’s automotive out of the blue sits alone – guidelines full. However on the opposite facet of the storage, there’s appreciable work happening with Hulkenberg’s automotive, which nonetheless has its ground on.
“We had a number of repairs to do as effectively and a small brake situation, which we needed to exchange,” explains Thompson. “So, it wasn’t like an enormous quantity, however all of the little issues simply add up.
“Nico additionally had a imprecise query concerning the brakes. So, you may’t simply go into the race realizing you’ve got acquired a imprecise query, are you able to? It’s important to take each precaution doable and simply work from there.”

Whereas this is occurring, Brown is nonchalantly scrolling by way of a 3D map of Haas’s braking methods on a display within the center financial institution of computer systems and standing desks that cut up the group’s storage. To his proper, the cockpit of 20 automotive is pleasingly casually hoovered to take away the mud and detritus that’s significantly an issue at this venue.
Because the mechanics attain 63 minutes into their allotted 150, the ground is lastly off Hulkenberg’s automotive. Right here, a brand new factor arrives within the type of an FIA scrutineer making a speedy evaluation of this automotive’s engine cowl. Minutes after he’s swiftly departed, there are extra inspections from totally different officers.
This time, there are checks beneath Hulkenberg’s proper sidepod which can be repeated on the left-hand facet of Magnussen’s machine. Recognizing telephones being shoved into the respective neighborhood, Brown explains how scrutineers are scanning QR codes for price cap compliance on numerous elements utilizing a devoted app. They’re checking that these have been purchased and invoiced accurately by the group.
It is now 70 minutes post-FP3 and the brake drums are actually again on automotive 20, whereas 10 minutes later the ground is fitted again on its sister – simply as a Sauber automotive fires up noisily within the neighbouring storage to our left.
A short time later, a 3rd FIA scrutineer arrives. This one prods and pokes Magnussen’s beam wing vigorously, at one stage shoving an entire finger right into a gap. After shifting to ruffle the Dane’s rear wing he shares a joke with Brown.
“I do know them – a few of them, very effectively,” he says. “As a result of I’ve labored with them beforehand. It is best to have a very good relationship with these folks.”
Because the 100-minute post-FP3 approaches, Magnussen’s ground is carried again by way of the storage and fitted again on. It’s at this stage a plate of quesadillas is dropped at Hulkenberg’s facet of the storage – two of his mechanics did not have an opportunity to eat earlier. They lastly accomplish that whereas they work, the restrict of this job unrelenting.
Subsequent, group proprietor Gene Haas wanders by way of the scene, shortly earlier than the bodywork is lastly all again on Hulkenberg’s automotive.

As we hit 120 minutes since FP3 has ended, it’s time to reverse what this era known as. It’s out of the blue gone amber with new hype on the stress not one of the Haas crew are exhibiting pressure beneath – the display clocks ticking down from a brand new 30-minute timer forward of qualifying. Changes to some elements – suspension, for instance – are not doable if the automotive concerned goes to make it out for Q1’s graduation.
With 28 minutes to go, the scrutineers are again – this time to place stickers on numerous bits of each automobiles, primarily across the entrance wing, rear wing and ground.
“Since you’re beneath parc ferme circumstances, these gadgets you may’t change after that time,” explains Brown.
“And there is sure elements of the ground that bolt on and off, so you may change them [illegally, without the stickers’ protection].
“A latest one which they’ve began doing is placing stickers on the skids on the finish of qualifying they usually come examine earlier than the race. As a result of, I assume, another groups have been altering the skids. You may’t do this…”
With 27 minutes to go, the bodywork is now all again on Magnussen’s automotive, whereas right here Hulkenberg’s is lowered to the bottom. Bodywork sealing tape utilized, his mechanics begin clearing their workstations of varied instruments and containers.

However with 26 minutes to go, it is out of the blue all motion round Magnussen’s automotive. Having been by far the better job on this event, there’s a twist.
“Simply as we closed the whole lot up, somebody from [team engine supplier] Ferrari mentioned they’d like to vary one thing that they’d seen on the opposite automotive, which wasn’t fairly proper,” Parkes explains.
“It was a little bit of a late name. There wasn’t actually a lot time left, so we took the bodywork again off to get entangled.”
Whereas this motion is ongoing to his proper, Komatsu walks again by way of along with his headphones on, steely competitor’s glint in his eye. However 5 minutes later, the late work is full on Magnussen’s automotive and it too is lowered to the bottom.
Getting to fifteen minutes out and the amber group screens flip an indignant purple, at which level Crolla addresses the squad as soon as once more. It’s so near consideration going again out on observe and the intense stuff of each F1 weekend.
Because the 10-minute mark pre-qualifying arrives, Komatsu alerts the entire group about what’s anticipated all through the upcoming session, the place each automobiles will attain Q3.

Right here, Hulkenberg saunters again into storage. He’s weighed and places his balaclava and helmet on – round last discussions along with his crew and Gannon. A couple of minutes later, Magnussen does the identical factor.
Three minutes out, the tyres are fitted for Q1 and the qualifying fire-up course of can kick off once more – this time for actual motion for the VF-24s. The workers devoted to honing their respective states can solely stand again and watch because the outcomes are available in, this vital course of full…
When this course of will get actually sophisticated
“FP3 was wonderful, the whole lot was utterly beneath management,” Thompson concludes as he remembers probably the most intense FP3-qualifying course of Haas has had to date in 2024.
“The job checklist was fairly small; the whole lot was simply too clean. After which 10 minutes earlier than the session, we realised one of many rain lights wasn’t engaged on the rear wing and it is like, ‘OK, effectively, it is most likely only a mild that might have failed’. So, we checked the sunshine, wasn’t that. Traced it again to a different wiring fault. And once more, clearly, you are in parc ferme after so we needed to repair it.
“Our wing swap usually takes half an hour, however we solely had 10 minutes to do it. Everybody simply needed to pile in collectively, cease their regular jobs and simply assist change the wing. And I feel we made it out 30 seconds late or one thing. However, up till that time, it was fairly relaxed and clean.”
“The workload, I might say, is greater,” Parkes says of how at Haas, the efforts made to vary engines and gearboxes on Friday evenings post-FP2 at non-sprint weekends really imply a larger checklist of duties to finish in comparison with what we’ve simply noticed.
“However after FP3, it is simply vital you do not make any errors…”
