In Fernando Alonso’s first System 1 season with Aston Martin, 2023, he claimed six podiums within the first eight races and was operating 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.
Lance Stroll 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 automotive has not began the season properly, seeming to have a elementary downside with race tempo. Stroll’s tendency to qualify poorly after which decide up positions partially masks a pattern of the automotive 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 bought a return within the type of two factors (and it will have been one however for Max Verstappen’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 observe, normally by way of a sneak assault.
“We lacked prime velocity, so on the straights we have been shedding so much,” 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 standard place to overhaul, however we have now to invent these sorts of strikes.
“Additionally in Imola I used to be out of Flip 7 after I made three overtaking [moves] in the previous couple of laps. So we have to resolve this case and begin overtaking on the straight with the DRS like everybody [else] does.”

“We have to enhance a little bit bit our straightline velocity and likewise the [tyre] degradation. As I mentioned, Saturdays are fairly aggressive and Sundays we appear to take a step again.
“So completely satisfied for at present for certain, 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 automotive to be a little bit bit extra Sunday-biased than Saturday-.”
Alonso might be relied upon to spotlight his personal contributions to a outcome with the keenness of a carnival barker. However each he and chief trackside officer Mike Krack alluded to the automotive being under-balanced, with an excessive amount of understeer.
It’s frequent for groups to arrange their vehicles to have an understeer steadiness at circuits equivalent to Barcelona as a result of the rear axle is the essential one, and a few understeer will help shield the rear tyres. However when requested by Motorsport.com if the issue was attributable to 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 automotive 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 bundle represented the primary definitive output of the newest regime and the brand new wind tunnel.
It was by no means going to be price half a second a lap, however CEO and group 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 automotive has a weak entrance finish – i.e. understeery – nevertheless it isn’t doing an awesome job of thermally managing its rear tyres both, and on the identical time it’s comparatively drag-inefficient. The mix of gradual straightline velocity 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 group can’t simply minimize downforce as a result of the automotive 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 set new tyres, new tyres, new tyres, new tyres. You masks a whole lot of the issues that the vehicles are having.
“This isn’t just for our automotive, that is for all of the vehicles. That can also be why you see the small gaps in qualifying. As a result of all of the weaknesses the vehicles are having are being lined by the brand new tyres, by the brand new rubber.
“As quickly because the tyres develop into two laps, three laps, 4 laps outdated, the weaknesses develop into increasingly more. That’s the reason you see that the vehicles within the entrance are simply going. That’s the reason the sphere is spreading a lot.”
Noticeably, Aston Martin has been ‘scrubbing’ its race tyre units – primarily giving them a brief run, normally throughout observe, to place a warmth cycle by them. The method of bringing the tyres as much as working temperature after which cooling them once more modifications 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 may well make the tyres much less delicate to graining and thermal degradation. Peak grip is decrease, however the purpose is to make the length 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 group since its Drive India days, when he helped Sergio Perez develop into a ‘tyre whisperer’. Earlier than that he labored for Bridgestone. It was Matsuzaki who first labored out that Pirelli’s rear tyres in 2013 may run longer stint lengths when mounted in the other way they have been designed to rotate.
So it’s unlikely that Aston’s efficiency deficit is being attributable to 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 imagine the group now has a deal with on the issue: “I believe we all know what is occurring…”
