Mercedes have been pre-season favourites for 2026 lengthy earlier than any of the brand new vehicles ran on observe, and nothing that occurred within the Method 1 ‘shakedown’ in Spain this week has modified that.
The brand new Mercedes made a powerful impression on rivals. The staff did essentially the most miles, and set the quickest instances whereas the automobile was on the observe, albeit Lewis Hamilton posted the quickest time of the week late on the ultimate day within the Ferrari.

The seven-time champion’s lap of 1 minute 16.348 seconds pipped George Russell’s finest for Mercedes, set the day past, by 0.097 seconds. World champion Lando Norris was second quickest on the ultimate day, and third total, within the McLaren, 0.246secs off Hamilton.
Judging efficiency from pre-season testing is all the time fiendishly tough due to the variety of variables concerned, all of the extra so after every week akin to this.
The check was held behind closed doorways, with no impartial media allowed entry. No official timing was launched. Solely only a few images have been taken, and most of these have been vetted by the groups who launched them.
The check was precisely the way it was billed – a shakedown is motorsport terminology for giving a automobile a primary run-out to verify every little thing works.

On high of that, every little thing the groups have been utilizing was new – vehicles, engines, tyres and gas – after the most important regulation change within the sport’s historical past.
Testing outright tempo was very a lot not on the agenda for anybody. So the headline lap instances meant virtually nothing, not that that erases the final impression that Mercedes are in one of the best place at this early stage.
The check was all about studying concerning the new vehicles and, notably, the brand new power-units. It was held in non-public as a result of groups have been scared by recollections of the final time new engines have been launched, in 2014, when many suffered main reliability issues.
However these fears didn’t come to fruition, partly as a result of the requirements in F1 are so excessive as of late, and partly as a result of the know-how change was not as large as final time. If something, the engine know-how, a minimum of, is less complicated.

The engines now have 50% of their whole energy produced by {the electrical} a part of the hybrid engine, and would require way more power administration than ever earlier than in F1.
However there may be now just one hybrid aspect to the engine, albeit that it produces thrice as a lot energy, following the elimination of the MGU-H, which recovered power from the turbo and exhaust. This implies a number of power restoration, and optimising that for lap time will take loads of studying.
Totally sustainable fuels, created from waste biomass or artificial industrial processes, have added a brand new complication, as they burn otherwise from fossil gas petrol.
As for the chassis, the vehicles have much less downforce than final 12 months, are smaller and narrower, however sooner in a straight line, that velocity boosted by moveable entrance and rear wings.

“There’s a whole lot of pleasure, not solely in Ferrari however round the entire paddock,” Hamilton’s team-mate Charles Leclerc mentioned.

“We have now to adapt as drivers and groups to try to discover methods to maximise what’s our new package deal, particularly now with this power administration that’s a lot greater than prior to now.”
Groups have been allowed to run on a most of three days of their selecting out of the 5. Mercedes had not solely accomplished all their working by Thursday, however they completed earlier than even the tip of the day.
Russell was typically optimistic concerning the new-style vehicles.
“It is vitally totally different,” he mentioned, “however while you wrap your head round it, it feels fairly intuitive.
“From a fan perspective, there is a chance to see extra thrilling racing, and I do not suppose you will notice probably a few of the negatives we are going to really feel from the automobile when it comes to the recharge, however that can evolve a lot over time.

“General, I am simply actually glad the vehicles are smaller now. I used to be a fan of the larger vehicles once they got here in in 2017, visually, however having pushed them, they have been too large, and now they simply look cool.”
Ferrari additionally ran reliably and so, most impressively, did the 2 Crimson Bull groups.
Crimson Bull are beginning this new period of F1 with their first in-house engine, developed at the side of new companion Ford. Russell went on file to say how impressed he was that the automobile had run so trouble-free.
The largest drawback Crimson Bull appeared to have on the check was driver-inflicted. The staff made the considerably odd determination to run within the rain on Tuesday, one thing solely Ferrari did as nicely.

New driver Isack Hadjar crashed within the afternoon within the fast last nook, having simply switched from full moist tyres to intermediates. The Frenchman did sufficient injury that the staff wanted to ship in new components, and Crimson Bull couldn’t run once more till Friday even when they’d wished to.
Most groups had issues of some form or one other, although.
World champions McLaren began the check late, as a result of the automobile was not prepared till Wednesday.
They mentioned that was a deliberate determination to make sure they’d as a lot design and improvement time as attainable, and it appeared to haven’t affected them when Norris impressed on the primary day of the automobile’s working on Wednesday.

However McLaren’s late arrival meant their flexibility was lowered, and when a fuel-system problem occurred on Thursday, they misplaced a whole lot of working time once they determined to strip the automobile down and guarantee they absolutely understood the issue.
For all of the focus on reliability, groups have been in fact attempting to glean any snippets they may about relative tempo.
Alpine managing director Steve Nielsen mentioned: “We’re all lap instances, in fact, attempting to guess what gas hundreds everybody has received.
“You speculate about different individuals’s and also you attempt to persuade yourselves you are aggressive, however by the tip of the Bahrain checks (in February) we are going to see lengthy runs, which is the place you do your calculations.”

As ever right now of 12 months, on the file the groups have been giving nothing away, emphasising they did not – could not – know the place they stood. And just about each single one uttered the phrase “optimistic” about how the check had gone for them.
Staff insiders, although, say an image did appear to emerge. Unsurprisingly, the highest groups look in fine condition. So far as it’s attainable to inform, behind Mercedes, Ferrari, McLaren and Crimson Bull all appear to be in an analogous aggressive ballpark – or “throughout the noise of knowledge,” as individuals in F1 prefer to say.
Alpine, who completed final in 2025, appear to have made a big step ahead having switched to Mercedes buyer engines. They, Racing Bulls and Haas are the midfield, it appears.
The brand new works Audi staff, the German producer having taken over Sauber and produced their very own engine, have been stymied by a good few reliability issues early within the check.

And all-new Cadillac, as anticipated, are on the again, was the final view.
One large factor all of the groups realized was that on-track working meant fast studying and progress, due to the complexity of the brand new vehicles, and the time it takes to construct up the data to getting one of the best out of all of the methods.
This might be why the manufacturing facility groups of Mercedes, Ferrari and Crimson Bull did so nicely, as they’ve essentially the most expertise of what their new engines want and the way they need to be run.
And this implies Williams, who didn’t even attend the check as a result of their automobile was not prepared, are considerably on the again foot going to the ultimate two checks in Bahrain as a result of they are going to be successfully two weeks behind everybody else.

Maybe essentially the most intriguing facet of the check was the extremely anticipated new Aston Martin.
The automobile arrived late – the staff didn’t run till late on Thursday and the automobile stopped on observe with Lance Stroll on the wheel after simply 4 very gradual laps. So successfully their check was only for sooner or later, with Fernando Alonso within the automobile.
However they definitely turned heads. The primary Aston Martin design led by the legendary Adrian Newey, it bore many variations from the opposite vehicles, from its broad nostril with its underside bulge, via its entrance suspension, slim sidepods and shrink-wrapped engine cowl.
That is the primary automobile for which Aston Martin have designed their very own gearbox for a few years, having purchased Mercedes gearboxes beforehand.

They’ve a brand new engine partnership with Honda. Newey joined solely in March final 12 months, and new chief technical officer Enrico Cardile, previously of Ferrari, in August.
And they’re beginning work with a brand new wind tunnel and driver-in-the-loop simulator, about which
Alonso, was second final on the time sheets, forward solely of the Cadillac of Valtteri Bottas, and greater than 4 seconds slower than Hamilton.
However the veteran two-time champion, who could possibly be going into his last season in F1, did handle to finish greater than 60 laps, to get his staff’s data-gathering off to an inexpensive begin.

Alonso mentioned: “A number of the groups did filming days and shakedowns to start with of January after which the entire weekend right here in Barcelona, however for us it was the very first day.
“We had a optimistic one, 60-plus laps and the automobile is responding nicely. Extra to return.
“It was particular. The primary automobile made by Adrian, along with Honda and all these new guidelines. We simply made it to Barcelona the previous two days. Great effort from everybody and looking out ahead to Bahrain now.”
