Aston Martin is introducing a major Honda power unit upgrade at the Dutch Grand Prix in Zandvoort. Enabled by the FIA's ADUO rule for underperforming engines, this internal redesign aims to increase power and improve drivability. Combined with recent chassis upgrades, the team hopes to make a \"reasonable big step\" forward in performance and reliability.
The summer break is here. The factories are closed. The drivers are on a beach somewhere.
But inside the Aston Martin garage, the real work is just beginning.
When Formula 1 returns at the Dutch Grand Prix in Zandvoort,
Aston Martin will not just be bringing a rested team.
They'll be bringing a completely new heart for their car.
Honda has confirmed that they're introducing a major power unit upgrade at Zandvoort.
And this isn't just a small tweak.
This is a fundamental redesign of the engine internals,
made possible by a special FIA rule that Honda was forced to use
because their engine was simply too slow.
But what exactly is changing inside this engine?
How much faster will it make Fernando Alonso and Lance strong?
And why is Zandvoort the absolute perfect place to test it?
Well, let me get into it.
To understand why this engine upgrade is happening now,
we have to look at a new rule for the 2026 season.
It is called ADUO, which stands for Additional Design and Upgrade Opportunities.
In simple terms, the FIA measures the performance of every engine on the grid.
If your engine is too far behind the best engine,
you're allowed to make upgrades to catch up.
At the start of the season, the FIA measured all the engines.
They found that the Red Bull Ford engine was the strongest,
and they found that the Honda engine in the back of the Aston Martin was the weakest.
In fact, the Honda engine was more than 4% behind the benchmark.
Because they were so far behind, the FIA gave Honda permission
to make two major upgrades to their engine across this season and next season.
Honda has decided to use their first upgrade right now at Zandvoort.
But what are they actually changing?
When you hear new engine,
you might think they're ripping out the whole back of the car and starting over.
But that is not what is happening.
Shintaro Orihara, who is Honda's trackside general manager,
explained exactly what they're doing.
He said that all the changes are completely internal.
They're not changing the size or the shape of the engine on the outside.
This is crucial because it means Aston Martin does not have to change their chassis
to make the new engine fit.
It is like doing a heart transplant without opening the chest.
The outside stays exactly the same, but the pump inside is completely new.
Inside the engine, Honda is focusing on three main things.
First, they're changing the shape of the combustion chamber.
Second, they're modifying the pre-chamber.
And third, they're changing the lubrication system to reduce friction.
By making the engine burn fuel more efficiently
and by reducing the friction of the moving parts, you get more power.
It is basic physics, but in Formula 1,
finding that power without breaking the engine is the hardest job in the world.
That brings us to the big question.
How much faster will this make the car?
If you look on social media, you will see some wild numbers.
Some Italian journalists have claimed the new engine will bring 50 extra horsepower.
Other rumors say it will be worth half a second per lap.
But what does Honda actually say?
Orihara was very honest about this.
He said he knows the exact number from the dyno testing in Japan,
but he's not allowed to say what it is.
However, he did give us a very clear warning.
He said,
We are aiming to get a reasonable big step rather than bring a small step,
but I would say there is no magic in Formula 1.
I don't think we're going to catch up to Mercedes or Red Bull by one step,
but we're going to bring a reasonable big step.
This is the reality check that Aston Martin fans need.
This engine is not going to suddenly put Fernando Alonso on pole position,
but it is going to fix the biggest weakness of the car.
And we already know the engine works because it has already been on track.
On July 29th, right after the Hungarian Grand Prix,
Aston Martin stayed at the track for a filming day,
and it just so happened to be Fernando Alonso's 45th birthday.
While most people get a cake for their birthday,
Alonso got a brand new Honda engine.
Aston Martin's third driver, Jack Crawford,
drove the car for 200 kilometers with the new engine installed.
Honda confirmed that the test was successful.
The engine ran, it collected data, and it didn't blow up.
That is step one completed.
Step two is Zandvoort, and Zandvoort is a fascinating track for a new engine.
The Dutch Grand Prix is not like Monza or Spa.
It doesn't have massive long straights where top speed is the only thing that matters.
Zandvoort is a medium downforce track.
It is twisty, it is fast, and it requires a lot of drivability from the engine.
Earlier in the season, the Honda engine had a massive problem with drivability.
The engine vibrated so badly that Alonso said he couldn't drive more than 25 laps
without risking nerve damage in his hands.
It was brutal.
Zandvoort will test whether Honda has fixed that problem permanently.
If the new engine is smooth out of the slow corners,
and if it delivers power cleanly through the banked corners,
that will be a bigger victory than just top speed.
But this engine upgrade does not exist in a vacuum.
It is the second half of a massive rescue mission by Aston Martin.
Just one race ago in Hungary,
Aston Martin brought a massive upgrade package to the chassis of the car.
They brought 16 new parts.
They changed the nose, they changed the floor,
and they took a huge amount of weight out of the car.
And it worked.
In Hungary, Alonso made it into Q2 for the first time all season.
The data showed that the car was nearly two seconds a lap faster
than it was at the start of the year.
So think about what is happening at Zandvoort.
Aston Martin now has a chassis that is two seconds faster,
and they're pairing it with an engine that has more power and less friction.
For the first time all year,
the aerodynamics and the engine are moving forward at the same time.
Mike Crack, the team boss at Aston Martin,
spoke about how hard this year has been.
He admitted that the relationship with Honda was very difficult
at the start of the season when the engine was bad.
He said,
It's easy to point the finger,
but we sat together and we said,
we're in this together,
we need to work hard to get out of it together.
Believe me, it was tough,
but it is something you have to go through,
and then you improve from there.
That is what makes Zandvoort so important.
It's not just about lap time,
it's about trust.
Aston Martin and Honda are going to be partners for a long time.
If this engine upgrade works,
it proves that Honda can identify a problem,
use the rules to fix it,
and deliver a better product.
It builds trust between the factory in England and the factory in Japan.
And there is one person watching this trust building exercise very closely,
Fernando Alonso.
Alonso's contract expires at the end of 2026.
He has said he will make a decision about his future during this summer break.
He's made it very clear that his decision
is not just about how fast the car is right now,
it's about whether he believes the team is moving in the right direction for the future.
Adrian Newey, who is now leading the technical side of Aston Martin,
said that Alonso wants to see clear, tangible progress.
While a chassis that is two seconds faster,
and a brand new engine that will only add to that,
is exactly what tangible progress looks like.
But we have to be realistic.
Even with the new chassis and the new engine,
Aston Martin is still fighting from the back.
They are currently second last in the Constructors' Championship with just one point.
Kimi Antonelli is leading the championship for Mercedes.
Lando Norris is now winning races for McLaren.
The front of the grid is miles away.
Mike Crack warned fans not to expect miracles on Friday at Zandvoort.
He said,
I don't expect we'll be straight away on it in FP1.
It might even take us a couple of sessions to get the maximum out of it.
When you put a new engine into a new chassis,
it takes time to understand how they work together.
The drivers have to learn how the power delivery feels.
The engineers have to map the software to make sure the battery
and the engine are working in perfect harmony.
Zandvoort is going to be a test session disguised as a race weekend for Aston Martin.
But if they get it right,
the second half of the 2026 season could look very different for the green cars.
They might finally be able to fight with the midfield
instead of just fighting with the Cadillacs at the back.
The summer break will be over before you know it.
The new engine is built.
The filming day is done.
Now it's time to see if Honda's rescue mission has actually worked.
What do you think?
Will this new engine finally push Aston Martin back into the points?
Or is the gap to the front just too big to close this year?
Let me know in the comments below.
And until next time, drive safe and bye for now.
