An Oil Stain on a Brand-New Power Unit: Aston Martin Pays With Both Cars at Baku

Nine laps. That was the entirety of Fernando Alonso's second practice session at Baku before his Aston Martin was pulled back into the garage. He finished at the bottom of the timing sheet. No meaningful lock-up, no botched corner exit. Just an oil stain under the floor tray and a chief engineer staring at the exhaust with an expression I learned to read after more than four decades on the pit lane.

What caught my attention was not the failure itself. It was that the power unit had just been installed. Aston Martin had fitted complete new units to both cars before the weekend began, accepting grid penalties from the back of the field. And on the very first run with the new powertrain, the oil came back.

At 57, I have spent enough evenings in garages to know one thing: a failure that appears immediately after a component change is a form of confirmation. Every collapse has a precondition; few people simply bother to look beforehand.

Baku is always the round I watch most closely among street circuits, because it exposes everything a team wants to hide. Barriers sit centimetres from the racing line, run-off barely exists, and any car that is not ready will confess within the first three laps of practice. Aston Martin confessed after nine.

The current technical cycle is the 2026 cycle: the moment Honda became Aston Martin's factory power unit partner, the moment Cadillac joined the grid with Valtteri Bottas in its line-up, and the moment Mercedes was led by George Russell alongside Kimi Antonelli, the man currently leading the drivers' standings. In that picture, Aston Martin sits at the opposite end of the spectrum, not because of drivers and not because of aerodynamics, but because of the one item no team can compensate for with talent: powertrain reliability.

The sporting regulations allow each driver four internal combustion engines per season, with corresponding allowances for the turbocharger, the energy store, the control electronics and the ancillary component set. Exceeding an allowance adds grid places per component. Accumulating more than fifteen places drops a driver to the back of the grid, and any further places become meaningless.

That is the entire rulebook. No grey area, no technical appeal. Aston Martin did the maths and accepted the terms.

From the start of the weekend, both cars carried the latest power units. Both Fernando Alonso and Lance Stroll were sent to the back of the grid regardless of qualifying. Administratively, this is standard practice: bundle all penalties into a round already written off, preserving component headroom for higher-value circuits later.

The component consumption sheet is where the story turns ugly.

Fernando Alonso has moved onto his fifth internal combustion engine, his fifth turbocharger and his ninth ancillary set. Lance Stroll has moved onto his sixth turbocharger, his seventh energy store, his sixth control electronics unit and his eighth ancillary set. The allowance is four. No reading of those figures makes them normal.

I track each team's component ledger as a professional habit, and I set one rule for myself long ago: when a car consumes ancillaries at the eighth or ninth set while the engine and turbo have only just crossed the threshold, the problem usually does not lie in the quality of a part. It lies in the environment that part has to survive in.

Ancillaries are the least glamorous components on television. They include pumps, pipework, cooling systems and similar hardware that absorbs heat and vibration directly. A team that replaces its ancillary set three times while the engine survives is usually fighting temperature or oscillation, not a discrete manufacturing defect.

What made me pause longer was the asymmetry.

Fernando Alonso is burning through the combustion side: engine and turbo. Lance Stroll is burning through the hybrid side: energy store and control electronics. Two drivers at one team, sharing one power unit philosophy, yet travelling in opposite directions across the allocation sheet.

There are two readings. The first: Aston Martin faces two independent failure modes, and its engineering office is deliberately rotating components so both cars never break at the same point. The second: this is firefighting, replacing whatever failed first or whatever sits on the shelf, with no long-term plan at all.

My years of watching lean toward the second reading more than Aston Martin's communications team would care to admit.

Years ago, while working within a coaching staff, I was tasked with validating the motion dataset from twenty Serie A matches for a major club. The expected-goals figure at the home stadium ran far higher than the away figure, yet actual goals were identical. The cause was not the strikers. It was a sensor mounted at the wrong angle, lagging two-tenths of a second, skewing every build-up from the goalkeeper.

That lesson has followed me throughout my career: when a system returns an absurd result consistently, suspect the system before you suspect the people. Every tracking figure belongs on the operating table, not on the altar.

Applied to Aston Martin, the system here is the integration package between chassis and power unit. A fresh engine leaking oil within nine laps does not by itself say Honda builds poor engines. It says that somewhere between the oil lines, the cooling system and the engine bay layout, there is a point where pressure or temperature exceeds the design threshold.

I do not have raw telemetry to prove it. But I have enough circumstantial evidence to ask the question, and in this trade, asking the right question matters more than reaching a conclusion early.

Strategically, Aston Martin's situation at Baku is not complicated. Starting from the back, both drivers get a free tyre choice, can extend the opening stint beyond their rivals, and can split strategies between the two cars. On a circuit where the safety car appears frequently, that is the classic recipe for salvaging a point or two from chaos.

But that recipe requires one thing Aston Martin does not have: long-run data.

Fernando Alonso completed only nine laps in the session that matters most for car setup. Nine laps on the streets of Baku are not enough to tune suspension for the cobbled sections, not enough to find the braking reference for corners that run flush against the walls, and not enough to build confidence in a car on sections where the margin is measured in centimetres.

In that session, both Aston Martins sat at the bottom of the times. Mercedes took the top two positions, with George Russell fastest and Kimi Antonelli, the championship leader, immediately behind. The distance between the two ends of that spectrum needs no further analysis.

I have covered more than five hundred grands prix in my career, including a run of four hundred and six consecutive rounds without missing a single broadcast. That experience taught me to distinguish two kinds of crisis. The first is a performance crisis: the team knows where it is slow, there is an upgrade plan, and time will resolve it. The second is a reliability crisis: the team does not know which lap the car will let go, and every weekend becomes a gamble.

Aston Martin is in the second.

My tracking of street circuits across recent seasons places Baku among the leaders for safety car deployments. That is why Aston Martin's strategists will not abandon the weekend. But the probability of a safety car does nothing for an engine that is leaking oil.

What is telling is the team's response. Fitting new power units to both cars in the same weekend is organisationally sensible, because it concentrates the penalties into one round and clears space for the rest of the season. It is only sensible if the root cause has been identified and fixed. When oil seeps again from the new unit, the premise of that decision collapses.

And this is where I want to turn away from the consensus.

Since news of the penalties spread, most commentary has pointed at Honda. The story being told is this: the Japanese manufacturer returned as a factory partner and immediately handed the team a power unit that cannot last. It is an easy story, a shareable story, and it slots neatly into a historical template.

But the component pattern does not fully support it.

If the problem lay in Honda's manufacturing quality, we would expect both cars to fail in the same way, in the same component group, at a similar rate. Reality shows the opposite: one car burning the combustion side, the other burning the hybrid side. That split does not indicate a defective part. It indicates an operating environment.

This is the execution blind spot I consider most important in the whole affair. When a factory-partner team hits a reliability crisis, political pressure always pushes blame toward the manufacturer, because that is the party that can be changed in the long run. Looking at the integration side, the cooling system, the engine bay packaging, the pipework routing, is far harder, because it forces the team to admit that its own side of the work is implicated too.

A contract only looks beautiful on paper until someone tries to fit it into a running system.

For a factory-partner team, there is no shield to hide behind. A customer team can change suppliers, at a cost in time and money. A factory team is locked into the relationship in both directions: it receives deeper technical support and development priority, and in exchange it cannot walk away when things break.

In the short term, the consequence shows up in the standings. Every round where both cars start from the back is a round where points are effectively zero. For a team built around title ambition, that kind of leakage is quiet, but it accumulates. It eats into end-of-season prize positions, into development budgets, and into the project's appeal to engineering talent.

In the medium term, the consequence shows up in reputation. Fernando Alonso is a two-time world champion. He is in the closing phase of his career, spending what remains of it at the back of the grid for reasons beyond his control. No driver accepts that calmly, and no team should assume he will accept it for long.

I once stood in a similar position, at a far smaller scale. During a match I was commentating, I posted that the defensive line was pushing too high, that failed pressing actions had passed the threshold, and that the goal would come from a high ball. The goal arrived exactly as described. Most of the response mocked me for turning emotion into arithmetic. But a major sports newspaper reproduced my diagram, and from that I drew a writing principle: if you want people to remember, translate data into spatial images.

Applied to Baku, the image is this. A brand-new power unit, not yet through a single racing lap, has left an oil stain on the garage floor. That image is not the image of a defective part. It is the image of an oil line forced to work outside its safe envelope, or a contact point absorbing vibration at a frequency the designers did not fully account for.

At Baku, where corner density and surface roughness impose unusual loads on the powertrain, such a weakness will surface faster than anywhere else on the calendar. Nine laps is a symbolic figure in the worst possible sense.

There is another possibility I do not rule out. Fitting the latest power units to both cars at this round may be the first deployment of a new specification, a durability update introduced early. If so, the oil leak is also bad news about durability after the attempted fix.

I do not have enough evidence to assert this. But it deserves monitoring, because it changes entirely how the coming rounds should be read.

So what does Aston Martin have left at Baku?

A strategy built on betting on chaos. Free starting tyre, a long opening stint, waiting for a safety car, switching to fresh softs for the closing laps and hunting a single point. On paper, that is the most rational plan from the back of the grid.

The condition for that plan to survive is simple and brutal: the power unit must complete the race distance. With a unit that leaked oil within nine practice laps, that is not a safe assumption.

If both cars finish without incident, it will be the best result the team can take away, whatever the finishing positions. If one of them lets go, the discussion about the nature of the problem will be forced into the open, and the pressure will move from the engineering office to the boardroom.

Data only tells part of the story; the rest lies where people know how to listen.

In this case, the data speaks plainly: penalty places, component counts, laps completed. The rest lies in what never makes the timing sheets: the pitch of an engineer's voice when he calls a driver back to the garage, the extended silence in Friday evening's technical briefing, and the words a communications team chooses when it says "new specification" instead of "failure".

None of that appears on a timing screen. But it is the earliest indicator of whether Aston Martin truly understands its own problem.

This weekend, I will watch three things. Whether the oil returns in final practice and qualifying. Whether the team runs the power unit in conservative modes during the race, a sign it knows it is walking on thin ice. And whether the component allocation sheet keeps climbing in the rounds ahead.

If all three happen, Baku stops being a story about one lost weekend. It becomes the opening chapter of a season limited by what no engineering office wants to admit: a technical marriage not tested long enough before it stepped into the light of the racetrack.
