Bottas 'Scared' by Aston Martin AMR26 Upgrade Rumors as B-Spec Breaks Cover

Valtteri Bottas has admitted to being "a bit scared" by the scale of Aston Martin's B-Spec AMR26 after rumors emerged that the upgrade keeps only the front suspension from its predecessor. The heavily revised car broke cover at the Hungarian Grand Prix, marking a pivotal moment in Adrian Newey's first full development cycle with the team.

Why it matters:

Aston Martin abandoned smaller in-season updates to channel resources into this single major overhaul after a dismal start to the 2026 campaign left them anchored at the back. For Cadillac, which has steadily pulled clear of Aston Martin through smaller but consistent upgrades, a sudden leap from the Silverstone squad threatens to reverse their progress and drop the American newcomers into last place.

The details:

• Bottas revealed he has heard speculation that "the only thing that is the same is the front suspension," with everything else on the AMR26 being new.
• While Cadillac has made reliable gains this season, Bottas acknowledged the team has no "magic" upgrade on the horizon and must soon shift focus entirely to its 2027 challenger.
• Cadillac arrives in Hungary with revised brakes offering more cooling after Bottas suffered brake fires at Monaco and Austria. He confirmed the old specification likely would not have survived the Hungaroring's punishing temperatures and heavy braking zones.
• Aston Martin's competition had been largely limited to Cadillac, but the B-Spec arrival could redefine the competitive order at the rear of the grid.

What's next:

All eyes will be on the timing screens this weekend to see whether Aston Martin's gamble pays off. If the car delivers the rumored massive step, Cadillac's remaining development window may not be enough to respond before the field switches focus to next season, potentially locking the two teams into a reversed battle for the remainder of 2026.
