Aston Martin reveals massive B-spec upgrade for Hungarian GP

Aston Martin has effectively introduced a B-spec version of the AMR26 ahead of this weekend's Hungarian Grand Prix, rolling out the largest single upgrade package seen in the Formula 1 paddock this season. The team broke curfew for the first time in the 2026 campaign to install 16 new components across both Fernando Alonso and Lance Stroll's cars, touching virtually every area of the chassis.

Why it matters:

The sheer scale of the refresh signals Aston Martin's intent to accelerate its development trajectory and close the gap to the leading pack. With the midfield tighter than ever and top teams bringing continuous improvements, a comprehensive package like this could prove decisive in the fight for crucial championship positions.

The details:

• Complete overhaul: New parts span the entire car, including the front wing, nose, front corner, floor body, floor corners, floor fences, floor edge, diffuser, sidepod inlet, engine cover, cooling louvres, rear suspension, rear corner, rear wing, beam wing, and both front and rear wing endplates.
• Paddock spread: Mercedes brought a new engine cover and tail, McLaren introduced a revised rear wing and floor adjustments, and Red Bull debuted a new floor alongside the return of its upside-down rear wing following Silverstone modifications.
• Quiet weekend: Alpine is the only team without any new parts, while Ferrari and Williams limited their changes to circuit-specific rear wing configurations.

What's next:

Honda is scheduled to deliver its first power unit upgrade for Aston Martin after the summer break at Zandvoort, which could provide additional performance on top of the chassis revisions. If the Hungaroring package proves effective, the team could carry significant momentum into the second half of the 2026 season.
