Honda Confirms Upgraded Power Unit Debut in Revised Aston Martin

Honda has confirmed its upgraded power unit will make its track debut in Aston Martin's heavily revised AMR26 at a Hungaroring filming day this week. The Japanese manufacturer will bolt the new engine into the B-spec chassis, giving both parties a crucial opportunity to validate the package before its first race outing at Zandvoort following the summer shutdown.

Why it matters:

Aston Martin has endured a miserable start to 2026, sitting at the back of the grid before a 16-part upgrade in Hungary. The revised AMR26 showed immediate promise as Fernando Alonso reached Q2 and Lance Stroll finished 13th, lifting the team into midfield contention. Integrating Honda's improved engine with this recovering chassis could prove the catalyst that accelerates Aston Martin's climb up the constructors' standings.

The details:

• Honda trackside general manager Shintaro Orihara confirmed the new power unit will run during a 200-kilometre filming day, providing a vital shakedown opportunity.
• The upgrade will not race until Zandvoort, making this private test the only chance to fine-tune the package before competitive action resumes.
• Aston Martin will also participate in a two-day Pirelli tyre test in Budapest alongside Alpine and Audi, gathering data for next season's compounds.
• Adrian Newey revealed further chassis updates are scheduled for Zandvoort, Monza and Baku, suggesting the Hungary package was merely the first step in the team's recovery plan.

What's next:

The coming races will test Aston Martin's development correlation. Newey noted that stage one of the AMR26 upgrade path aligned with simulations, giving the team confidence that subsequent steps will deliver as predicted. If Honda's engine produces the expected step and the chassis upgrades continue to hit their targets, Aston Martin could emerge from the summer break as a genuine midfield disruptor rather than the backmarker it was at the start of the year.
