Aston Martin is facing what could become one of the most significant days of its 2026 Formula 1 season as the team evaluates Honda’s latest power unit during Pirelli tyre testing at the Hungaroring.
A source close to TJ13, who is currently at the circuit monitoring today’s running, tells us the atmosphere around the test is one of cautious optimism, largely due to the relative success of the big update package that raced last weekend at the Hungarian Grand Prix.
Following the debut of an extensive aerodynamic and weight-saving upgrade package, attention has now shifted to whether Honda’s latest engine development can deliver the next major step forward before Formula 1 returns from the summer break.
If the test proves successful, the upgraded power unit is expected to be introduced at the Dutch Grand Prix at Zandvoort, completing another major phase of Aston Martin’s ambitious mid-season recovery.

Aston Martin builds on Hungary breakthrough
The Hungarian Grand Prix marked the first tangible reward for months of development work at Silverstone, with very little of Adrian Newey at the factory at the start, according to factory sources close to this website.
Further, grave concerns for the remaining 2026 campaign, and even the new 2027 car, began to creep into the minds of those within parts of the factory.
Yet, after spending much of the season towards the back of the field, Fernando Alonso and Lance Stroll were once again able to compete in the midfield following the introduction of a dramatic aerodynamic overhaul.
The team arrived in Budapest with no fewer than 16 new components on the AMR26, representing the biggest single upgrade package of its campaign, effectively making it a ‘ B-spec ‘ car from Hungary onwards. The performance gain immediately offered encouragement that Adrian Newey’s growing influence over the technical direction of the car is beginning to bear fruit.
However, Aston Martin always viewed Hungary as only the first stage of a wider development programme.
Today’s Honda engine evaluation represents the next critical milestone.
Honda upgrade could be worth half a second
Multiple reports suggest Aston Martin expects a meaningful improvement from Honda’s revised power unit, although nobody within the team is expecting overnight miracles.
According to the BBC, Aston Martin believes the combination of the updated engine and its improved chassis could ultimately be worth around half a second per lap.
With the team’s current deficit to Formula 1’s frontrunners estimated at roughly 1.5 seconds, such a gain would not suddenly transform Aston Martin into a race-winning contender.
Instead, the objective is to establish the team as a regular points challenger during the second half of the season.
Reports also indicate the revised Honda engine could deliver approximately 35 additional horsepower, providing another valuable performance boost alongside the aerodynamic improvements already introduced in Hungary.
The outcome of today’s running will therefore play a major role in determining Aston Martin’s development direction ahead of Zandvoort.
Adrian Newey has already promised more upgrades
Even before the Honda engine arrived, Aston Martin made it clear that Hungary represented only the beginning of an aggressive upgrade schedule.
Speaking during the Hungarian Grand Prix weekend, Adrian Newey confirmed that additional developments are already planned across the next phase of the calendar.
“We will have further steps in Zandvoort, Monza, and Baku. So this is just the first part of our package.”
Those comments underline Aston Martin’s intention to continue developing the AMR26 throughout the remainder of the season rather than waiting for the next regulation cycle.
Should today’s engine test prove successful, it would add another important piece to a package that is finally showing genuine signs of progress after a frustrating first half of the campaign.
A solid foundation for a performance recovery?
Although Wednesday’s Pirelli tyre test will not attract the same attention as a Grand Prix weekend, its importance inside Aston Martin should not be underestimated.
The team has already demonstrated that its substantial aerodynamic revisions have moved the car in the right direction. The remaining question is whether Honda’s upgraded power unit can provide the performance increase required to convert that progress into consistent points finishes.
With further developments already scheduled for Zandvoort, Monza and Baku, today’s running could become the foundation for Aston Martin’s most competitive period of the 2026 Formula 1 season.
