Aston Martin‑Honda unveil hardware upgrades for Miami GP

Honda and Aston Martin have rolled out a package of hardware changes aimed at eliminating the crippling vibrations that have plagued the team's 2026 power unit. The upgrades, tested on a chassis at Honda’s Sakura facility, are set to debut at the Miami Grand Prix, giving the team its first chance at a clean finish in 2026.

Why it matters:

The 2026 Aston Martin‑Honda combo has been stuck at the back of the grid, with drivers complaining of intense vibrations and battery reliability issues that forced the team to limit engine revs. Fixing those problems is essential for driver confidence, tyre wear management and, ultimately, scoring points in a tightly contested championship.

The details:

• Large vibration‑reduction package, addressing the source and mitigation across the power unit.
• Mechanical counter‑measures added to the engine – details not disclosed – to improve reliability.
• Battery side improvements reported, helping the MGU‑K recover energy more consistently.
• An experimental steering‑column component trialled at Suzuka reduced driver‑felt vibrations, but was not used in Miami as engine work made it unnecessary.
• Honda used a full‑car dyno set‑up at its Sakura test centre, allowing engineers to monitor engine behaviour on‑track in real time and even let trackside engineer Shintaro Orihara experience the vibrations firsthand.
• The FIA still limits performance upgrades until permission is granted, so the changes are classified as reliability fixes.

What's next:

• Honda awaits FIA clarification on the number of upgrades each power‑unit manufacturer may introduce this season, and on the vote to lift the cumulative‑upgrade cap.
• If the cap is relaxed, the team could start pushing engine performance, possibly lifting rev‑limits and exploiting the new 350 kW “super‑clipping” rule.
• Data from Miami and continued testing at Sakura will guide further refinements, with both parties promising to keep the development pace aggressive while staying within regulatory bounds.
