I have to think that Mclaren is working on a "Miami update" in the next couple of races. I agree that the project seems to be at a very immature state in all areas. Mclaren was trailing when they missed the first days of the Barcelona shakedown, and there is more evidence of that when Lando Norris didn't have a spare front wing for qualifying.
I'm going to throw in a wild theory I conjured up during Barcelona, but did not say it at the time.
And just in case some people take it a bit too seriously, I'll just put a disclaimer here. This is just speculation on my part based on my own perception. You don't have to agree with it.

Basically, I think McLaren's relatively slow start to the 2026 season could stem from them investing significant development time into a concept that ultimately turned out to be a dead end. They may have pivoted quite late to the current design, which left them short on refinement time compared to rivals. That would explain the delayed arrival at the Barcelona shakedown (they skipped the first couple of days to squeeze out every last bit of development back at the factory, by their own admission) and why the MCL40 looks, and I will emphasize here again, at least to my eyes, a bit more basic or conservative on the surface aero compared to the other top teams.

When McLaren announced they'd be late to Barcelona, my gut feeling was that they'd undergone a major late-stage philosophy shift, pushing everything right up against the deadline. The car was literally being finalized and built right up to the test, with no prior shakedown mentioned. Combine that with their statement that this is essentially the spec they'll race from the start of the season, and it gave me this immediate "that's it?" vibe on reveal day. Not because it lacks aggression, but because the aero surfaces feel a little too safe, straightforward, and perhaps underdeveloped for a team coming off a championship, almost like they had to rush the final iteration after scrapping or shelving something else.

Of course, I re-iterate here, this is pure speculation on my part. There's no concrete evidence or insider leaks pointing to a dud concept or dramatic mid-development U-turn, it's just a theory put together with the late test debut, the "juvenile"/basic look of the car, and the team's own comments about maximizing development time pre-track.

My intuition regarding the car hasn't really changed since seeing it roll out. I was basically simply waiting for confirmation that they're indeed in the back foot here. I do admit though, that I thought the gaps at the front would have been smaller than what we saw here in Australia. For all of them, not just McLaren.
To my eyes the McLaren doesn't look any better or worse than the Mercedes. McLaren had less wind tunnel time and had a championship to fight for last year. They don't have as much understanding of the PU compared to Ferrari and Mercedes for obvious reasons. Wild multi paragraph conjecture isn't needed at this point.

While these theories are interesting I suspect that the key deficit factor is still the optimisation of battery deployment. They got the latest spec of engine just before the race weekend so they didnt have the time to dial it in.

With that said, it's also possible that a Miami style update is in the works, and it just didn't make the cutoff for production ahead of Melbourne. That would change interpretations quite a bit. A so called b-spec car that is just delayed so they haven't started the year with the car that they really wanted. The "real" MCL-40 could appear at a later race.

The Race stated they have produced a bare chasis to spare their windtunnel time allocation, to wait and see specific solutions of others and to reverse engineer things they find interesting without using extra time for it.

Ofcourse as allways you need to take that with a pinch of salt, but on the other hand it is logical to leave yourself some extra hours available with such long season ahead and with a handicap. They have shown they are able to deliver proper updates in the past.

The season will tell us who has an overall best chasis, who is dependant of track temps., tyre deg, and who will have the best reliability.
It was not just The Race reporting it, one of the McLaren big shots said that publicly. I am not sure if it was Stella or Marshall. IIRC it was Marshall after a test day.

He basically said that he was worried someone would run away with it (funny too look at it now as Mercedes is far ahead) and that it doesn't seem like anyone did. Probably thought all concepts are similar and that no one figured a massive loophole. He then said that their plan is to bring a simpler, safer car which cost less development time and not rush upgrades forward until they know what is the most important area to improve and until they saw all the ideas other teams brought. We've mentioned it here. To me it seems like a smart way to catch up with less CFD time, but it carries with it a penalty at the start of the season.

Maybe that was what McLaren did in previous years, maybe that was their trick? Using less CFD early in the season to capitalize on it later on?


That being said, every team will say they intend to catch up to the leaders. It is a big question whether you can do that and out develop the other teams. McLaren is one of rare cases when it seemed to work but this is a new formula so who knows. We probably need to recalibrate our expectations this season, I am happy to see the most of the thread is taking it quite well, no meltdowns :D

It's more likely to be this. McLaren openly admitted to a conservative base model because they are the most restricted.

At the same time, Mercedes seems to be the most advanced in understanding the deployment mapping. That alone is a major advantage.

As outlandish and stupidly simple as it may seem, this is the 'theory' I have :

Did Piastri also crash out for the same reason as Verstappen yesterday?

I do believe in the PU theory just because all Merc customer teams seem to be underperforming with reliability/configuration issues.

I also think that is proving to be ironic. :lol:

I don't get it. What you see on track at any point lags the windtunnel by several weeks. Car debut was in the last week of january, so the launch spec MCL-40 was developed entirely in 2025. You can't carry over any of these resources into 2026. So what would be the idea that they have "saved development cost" in the initial design or the MCL-40?. You use it or lose it in 2025.

But since January 1st you can "save up". They could have just used up their 2025 allocation then starting January 1st they use much less then they could, intentionally saving the CFD/wind tunnel runs. Probably not a complete stop but an intentional choice to run things which you think are big upgrades. And now that they can identify areas they need most work on (for example rear axle) they can focus on that with more CFD/wind tunnel time (plus copy any solution they see that is good).

It's basically what Marshall said. It doesn't fit perfectly with being late to the shakedown *shrugs*.

Teams that brought big upgrades to Melbourne probably didn't "slow down" in 2026. They didn't have time to gather data in the test, design and bring upgrades. These first upgrades had to be done without on track data and that is worth less bang for your buck.

I think you haven't been following McLaren closely enough. The team's management has been quite open over the past few years, stating outright that they're starting the 2023 and 2024 seasons with a chassis they wouldn't have liked. I see no reason for them to start lying to their fans now. In recent years, McLaren has been trying to introduce updates comprehensively, so they'll have a noticeable effect, but it's clear that this takes more time. Especially since after testing, Marshall and Stella said they were happy with the base chassis, and we saw that in the race today. Once they figure out the engine, they'll get free time, and once they figure out the excess weight, they'll also get free time.

What else to expect if the sport has a wind tunnel alocation rules at reg change from a standings of a previous season.

I made this argument last year as well. FIA = Idiots.

Seeing McLaren this far behind is certainly very surprising to me. Either I overestimated their abilities and last regulation cycle was an one-off, or Emag's theory that they likely chose a different development route late makes a lot more sense.

This is the same reason McLaren could catch up. The pendulum swings both ways.

The allocations are designed to not keep the same team at the front. They are working perfectly in this regard

Bear in mind that Tunnel and CFD time are allocated to fixed Aerodynamic Testing Periods, which means to say if they don't use the time they lose it if they move in to the next period. Is each one about 8 weeks or something?

So there is only so much they can hold back.
