In ’s first Method 1 season with Aston Martin, 2023, he claimed six podiums within the first eight races and was working third within the championship. The pickings have been extra barren since then and within the Spanish Grand Prix – the ninth spherical of 2025 – he picked up his first factors of the season.
had scored all of Aston Martin’s factors till then – a humble 14, drawn from the primary two rounds.

Heads have already rolled in Aston’s technical division final season and the AMR25 automobile has not began the season properly, seeming to have a basic downside with race tempo. Stroll’s tendency to qualify poorly after which decide up positions partially masks a pattern of the automobile being slower on Sundays than it’s on Saturdays, although the one time this season he certified inside the highest 10 (at Imola) he completed fifteenth.
Alonso, although, has reached Q3 thrice and solely simply acquired a return within the type of two factors (and it could have been one however for ’s penalty). A notable characteristic of the primary and final rounds of this newest triple-header has been his tendency to overhaul at unconventional factors on the monitor, normally through a sneak assault.

“We lacked high pace, so on the straights we have been dropping rather a lot,” he mentioned in Barcelona. “I did not make a single overtake below DRS. They have been all made in Flip 3 on the surface, which isn’t a traditional place to overhaul, however we’ve to invent these sorts of strikes.
“Additionally in Imola I used to be out of Flip 7 once I made three overtaking [moves] in the previous few laps. So we have to resolve this example and begin overtaking on the straight with the DRS like everybody [else] does.”

“We have to enhance somewhat bit our straightline pace and in addition the [tyre] degradation. As I mentioned, Saturdays are fairly aggressive and Sundays we appear to take a step again.

“So completely satisfied for immediately for positive, first factors, good Security Automobile on the finish, good timing and issues. But when we return on Thursday and we redo the weekend, we have to change one thing on the automobile to be somewhat bit extra Sunday-biased than Saturday-.”
Alonso may be relied upon to spotlight his personal contributions to a outcome with the passion of a carnival barker. However each he and chief trackside officer Mike Krack alluded to the automobile being under-balanced, with an excessive amount of understeer.
It’s widespread for groups to arrange their automobiles to have an understeer stability at circuits reminiscent of Barcelona as a result of the rear axle is the essential one, and a few understeer may also help defend the rear tyres. However when requested by Motorsport.com if the issue was brought on by dialling in an excessive amount of understeer, Alonso’s reply was an unequivocal “no”.
Amongst Aston’s challenges final 12 months was that many of the efficiency upgrades added to the automobile didn’t generate the anticipated outcome. Whereas the AMR25 is the product of the earlier design management, at Imola a brand new ground and bodywork package deal represented the primary definitive output of the newest regime and the brand new wind tunnel.

It was by no means going to be value half a second a lap, however CEO and workforce principal Andy Cowell talked about it by way of a lab experiment to allow to stress-test its instruments and procedures.
What’s turning into obvious is that the automobile has a weak entrance finish – i.e. understeery – however it isn’t doing an excellent job of thermally managing its rear tyres both, and on the identical time it’s comparatively drag-inefficient. The mix of gradual straightline pace and detached tyre administration is a killer on Sundays.
Lack of aerodynamic effectivity is killing the AMR25 on two fronts: it’s gradual in a straight line, however the workforce can’t simply lower downforce as a result of the automobile will slide extra, making tyre efficiency worse.
“The distinction between the qualifying and the race is sort of easy,” mentioned Krack after the Barcelona race.

“In qualifying you place new tyres, new tyres, new tyres, new tyres. You masks lots of the issues that the automobiles are having.
“This isn’t just for our automobile, that is for all of the automobiles. That can also be why you see the small gaps in qualifying. As a result of all of the weaknesses the automobiles are having are being lined by the brand new tyres, by the brand new rubber.
“As quickly because the tyres turn out to be two laps, three laps, 4 laps previous, the weaknesses turn out to be an increasing number of. That’s the reason you see that the automobiles within the entrance are simply going. That’s the reason the sector is spreading a lot.”
Noticeably, Aston Martin has been ‘scrubbing’ its race tyre units – basically giving them a brief run, normally throughout apply, to place a warmth cycle via them. The method of bringing the tyres as much as working temperature after which cooling them once more adjustments the visco-elastic properties of the rubber.

It will be overly simplistic to say this improves grip and life traits on a linear scale, however there’s a perception it could actually make the tyres much less delicate to graining and thermal degradation. Peak grip is decrease, however the goal is to make the period of the height longer.
Aston Martin’s chief tyre efficiency engineer Jun Matsuzaki has been considered a key asset for a few years and has been with the workforce since its Drive India days, when he helped turn out to be a ‘tyre whisperer’. Earlier than that he labored for Bridgestone. It was Matsuzaki who first labored out that Pirelli’s rear tyres in 2013 might run longer stint lengths when mounted in the wrong way they have been designed to rotate.
So it’s unlikely that Aston’s efficiency deficit is being brought on by not getting the most effective out of the tyres by way of trackside operations. It’s a query of mechanical and aerodynamic design.
Alonso, for one, appears to consider the workforce now has a deal with on the issue: “I feel we all know what is going on…”
