The team recently debuted a heavily revised B-spec AMR26 chassis at the Hungarian Grand Prix , which successfully allowed Fernando Alonso to reach Q2 and qualify a season-high 16th.
But the real focal point for the Silverstone outfit is what is happening under the engine cover. During a recent 200km filming day at the Hungaroring, Honda shook down its highly anticipated upgraded power unit ahead of its official race debut at Zandvoort .
Naturally, the F1 rumor mill is already in overdrive. Leaks from Italian media and paddock insiders have presented wildly differing numbers regarding the actual performance gains. So, are we looking at a minor bump, or a season-altering leap? Let’s unpack the math.
The Debate: Aston Martin’s 35 HP vs. 40 HP
The core of the debate centers around two slightly different figures making the rounds on social media.
According to reports from AutoRacer Italia , Honda’s new power unit specification is expected to deliver around 35 horsepower. In Formula 1 terms, that specific report projects a lap time gain of roughly 0.5 seconds, which was corroborated by other F1 aggregation accounts .
However, the speculation goes even higher. As referenced in Motorsport Italia ‘s reporting, the revised engine could push an extra 40 HP. By applying historical benchmarks—specifically the much-discussed “Mercedes compression saga” where a 15 HP gain yielded 0.25 to 0.30 seconds—some analysts are projecting a massive 0.6 to 0.8-second jump in lap time for the AMR26.
Some Italian analysts, like Franco Nugnes, have even floated the idea of a staggering 50-horsepower boost , suggesting Aston Martin could finally fight the Racing Bulls, Alpine, and Audi in the midfield.

Under the stringent 2026 engine regulations, manufacturers are heavily restricted. However, because Honda started the year on the back foot, they are utilizing their first ADUO (Additional Development and Upgrade Opportunities) token. This FIA catch-up system allows struggling engine suppliers to modify their hardware to close the gap. According to Honda trackside general manager Shintaro Orihara, the engineering team spent the summer focusing heavily on “optimising combustion and reducing friction losses” to achieve these gains.
Setting a Realistic Benchmark
So, does 40 HP actually equate to 0.8 seconds in the modern era?
While it is tempting to use a linear mathematical projection, Formula 1 physics rarely works in straight lines. A long-standing technical benchmark in the paddock is that 10 horsepower is generally worth between 0.15 and 0.20 seconds per lap on an average circuit, depending heavily on track layout and aero efficiency.
The 35 HP Scenario: Using the standard paddock math, a 35 HP boost would yield between 0.52s and 0.70s. This makes the 0.5s projection entirely realistic, especially at a high-downforce, twisty track like Zandvoort where outright power is slightly muted.
The 40 HP Scenario: Pushing the gain to 40 HP gives a theoretical maximum of 0.8 seconds (using the 0.02s per 1 HP multiplier from the Mercedes saga). However, because aerodynamic drag increases exponentially with speed, the faster the AMR26 goes on the straights, the more horsepower is required to overcome the air resistance. Therefore, expecting a full 0.8-second return is likely overly optimistic.
Furthermore, the 2026 power units rely on a complex 50/50 power delivery split between the internal combustion engine and the electric MGU-K. A bump in peak combustion horsepower is useless if the car is actively clipping (running out of electrical deployment) at the end of long straights.
If Honda has successfully cured the severe vibrations that hampered their reliability earlier this year while unlocking a legitimate 35 HP, a 0.5-second jump is a highly credible benchmark. While it won’t instantly put Fernando Alonso back on the podium, combining a half-second engine gain with the aerodynamic benefits of the Hungary B-spec chassis could finally pull Aston Martin out of their 2026 nightmare.
Zandvoort will provide the ultimate stopwatch test.
