The RB20 and the 2026 Season: How Red Bull Locked Itself Into a Window Too Narrow to Win

On the afternoon of 25 August 2026, at Zandvoort, Lando Norris crossed the line 22.9 seconds ahead of Max Verstappen. It was the largest margin of the entire season, and it arrived at a race where almost nobody had placed McLaren as the number one contender before the cars rolled out. What made me stop was not the 22.9-second figure. It was that Verstappen, who would still hold the championship at the end of the year, had no answer for 72 laps. The car that had won 21 of 22 rounds in 2026 suddenly became harmless on the home circuit of the number one driver.

I have followed Grand Prix racing since 2026, and I once sat in the technical office of a Serie A club to validate motion-tracking data, and I have drawn one lesson from all of it: afternoons like that are never accidents. They are the result of decisions taken a long time earlier. Every collapse has a prerequisite; few people are willing to look for it in advance.

The 2026 season closed with McLaren taking the constructors' championship for the first time since 2026. The British team finished on 666 points, 14 ahead of Ferrari and 77 ahead of Red Bull. In the drivers' table, Verstappen scored 437 points and took a fourth consecutive title. Norris was second on 374, Charles Leclerc third on 356, Oscar Piastri fourth on 292, Carlos Sainz fifth on 290, George Russell sixth on 245 and Lewis Hamilton seventh on 223.

Read the standings and the story looks simple: a young team rises, an old champion fades. But the standings are the last thing written. They do not tell anyone why a car that once dominated became ordinary within a few months. And they certainly do not tell anyone that McLaren's title was largely settled by choices Red Bull made in the winter of 2026–24, before a single lap had been run.

I want to start there, not in Abu Dhabi.

Through that winter, the engineering paddock in Europe was talking about one thing: the RB20 was not a small step. It was a leap. Milton Keynes had won 21 of 22 races in 2026 with the RB19, a car designed in an extremely conservative way around the sidepod and floor. They could have kept that philosophy and simply refined it. Instead they chose another direction: narrowing the sidepod inlets into a vertical slot, changing how air was fed to the engine cover, and pushing the floor concept close to the limit of the regulations.

That was a decision with logic behind it. When you are at the top, rivals copy you. Stand still and you will be caught. Red Bull chose to create a new gap. The problem is this: every time you widen your design envelope, you also narrow your operating window.

This is the point that very few F1 observers bother to grasp. A fast car is not simply a car with high downforce. It is a car that can generate that downforce across many different conditions: changing track temperatures, changing altitude, changing tyre compounds, changing fuel loads, changing wind. The closer a design is pushed to the aerodynamic limit, the narrower that window becomes. And when the window is narrow, the car becomes extremely sensitive to the things a team cannot control.

At Bahrain, Jeddah, Melbourne and Suzuka, the RB20 still won. But look closely and a small signal appeared very early: the gap between Verstappen and the chasing group was no longer as large as the year before. At Imola the winning margin was under a second. In Canada, Spain and Austria, wins still came but with thinner margins. People who only read the result column will say Red Bull kept winning. People who look at the peak of the speed trace lap by lap will see something else: the advantage was contracting round by round, as steadily as a straight line.

I have a professional rule I drew from 2026, when I had to validate motion data from twenty matches for a major Serie A club. At the time, the expected-goals figure at home was far higher than away, yet actual goals were level. Everyone assumed it was a psychological issue. When I cross-checked the video against the sensor data, I found the real cause: a sensor in one corner of the stadium was lagging its signal, so every build-up from that area was logged in the wrong position. I wrote a fourteen-page internal report and recommended recalibrating the equipment.

I tell that story not to talk about football. I tell it to explain why I never trust a single number. Every tracking figure belongs on an operating table, not on an altar. Winning margin is a surface metric. It only means something when placed beside tyre degradation, top speed on the long straights, and average pit time.

Back to the RB20. When rival engineering groups began analysing images from free practice, they noticed something important: the RB20 took longer to bring its rear tyres into the optimal temperature range. That does not hurt over a single qualifying lap. It hurts over a long race. And it hurts most at circuits where the surface has low grip, ambient temperatures are high, or the driver is stuck in the turbulent air of the car ahead.

That is the mechanism behind Red Bull's bad run in the middle of the season. The car did not lose speed. The car became harder to predict. A hard-to-predict car forces the driver to compensate with skill, and when a driver compensates with skill for many laps, the tyres wear faster. Faster wear makes the pit strategy reactive. A reactive pit strategy costs the team control of its pit window. And once you lose control of the pit window, you lose the race in the strategy room before you lose it on track.

This is where McLaren enters the story.

The MCL38 was not a shocking car. It had no aerodynamic detail that made people photograph it and post it online. It was the product of continuous, steady and extremely disciplined development. What McLaren did best in 2026 was not a single breakthrough. It was keeping the car's operating window wide, stable and predictable for both drivers.

That is why Norris won in Miami, Zandvoort, Singapore and Abu Dhabi; why Piastri won in Hungary and Azerbaijan. Look at that list and you see something interesting: McLaren's wins are spread across very different circuit types, from low-grip street tracks to high-speed layouts. That is the signature of a car with a wide window. Red Bull won more, but their wins clustered in the early season, when the operating window was still wide thanks to cooler temperatures and fresh surfaces.

Read only the race results and you will conclude McLaren were the fastest team by the end of the year. Read the long-run data from free practice and you will see a subtler picture: McLaren were not always the fastest over one lap, but they were almost always the most consistent team across three consecutive rounds. In a 24-race season, that consistency is worth more than peak speed.

I have written before, and I still hold the view: data only tells part of the story; the rest lies with those who know how to listen. In this case the data spoke clearly. The rest was on the radio.

There is a detail I tracked all through 2026 that is rarely mentioned. It is the tone of the engineers' voices on the radio. When a team is controlling a race, the engineer's tone is even, short and declarative. When a team is losing control, the tone changes. Sentences get longer. There are more pauses between them. And questions appear that were not there before, such as confirming tyre state, or asking the driver how the car feels.

At Red Bull, from mid-season, those pauses became more frequent. At McLaren, they were rarer. This is the kind of signal that appears in no telemetry sheet. But to someone who has spent years in a technical office, it is as clear as a crack in glass.

Of course, I do not want to paint too clean a picture. McLaren had their own problems, and the biggest one sat with Norris himself.

Through the first half of the season, Norris lost several positions on the opening lap. This is a measurable problem. Build a table comparing grid position with position after lap one across all of Norris's 2026 races and a clear pattern emerges: he typically lost one to three places on the first lap. Over a long race, losing a place on lap one is not just losing a place. It is losing an entire strategy. You get stuck in turbulent air. Your tyres heat faster. And the pit window the team planned before the race becomes invalid.

That is why I disagree with the popular explanation that McLaren lost the drivers' title because Norris lacked nerve. It is an easy explanation, and it skips the hardest part of the story.

At Hungary in 2026, McLaren made a controversial strategy call by asking Norris to give the place back to Piastri. It was a race where the team put collective interest above individual interest, and they called it their internal principles. Mathematically the decision was not wrong. Psychologically it created a small crack in the racing room. And small cracks can widen over time.

But I want to offer a different reading of Hungary. Many people say McLaren squandered a chance for Norris to bank points. On the surface that is true. Look deeper and the decision showed something a championship team needs: the capacity to absorb short-term discomfort in order to preserve long-term stability. McLaren ended the season as constructors' champions by 14 points over Ferrari. Those fourteen points amount to a few positions across a few races. Had McLaren let the internal order fracture in Hungary, that number could have been different.

There is something here I call the execution blind spot. An execution blind spot is a mistake that sits neither in the car nor in the driver, but in how a team coordinates under high pressure. A pit call made one lap early. The wrong compound chosen as rain begins. Holding a driver on track too long when a safety car appears.

These mistakes do not show up on a speed trace. They show up in the weekend results, and they tend to repeat in patterns. That is why I always advise readers to study the post-race technical briefing minutes, not just rewatch the start.

In Red Bull's case, their biggest execution blind spot in 2026 was not on track. It was at the factory.

This is the part I want to spend the most time on, because it is the least discussed.

In May 2026, Red Bull confirmed that Adrian Newey would leave the team. He was the chief architect of the cars that had dominated the preceding era. The news broke while the season was running, and it coincided with the phase in which the RB20's performance began to plateau. Newey later joined Aston Martin.

I do not want to claim that one individual's departure was the sole cause of everything. That would be a lazy explanation. But I do want to say that the departure was a signal, and that signal sits within a larger chain of signals.

Over the same period, Red Bull faced a series of internal issues not directly related to engineering. Tensions in the leadership, disputes over power, and news unrelated to the track but constantly in the papers. For a racing team, none of that makes the car a second per lap slower. But it slows down decision-making. And in a season where the gap between the leading teams is measured in tenths, decision speed is a genuine engineering variable.

I have seen something similar in another context. In 2026, at a major tournament, I posted a view online about a national team's defence: their back line was pushing up an average of about 68 metres, their pressing was failing repeatedly, and the opponent had already produced more than ten counter-attacks. I wrote that if they did not drop the block, the goal would come from a ball in the air. Three minutes into stoppage time, the goal arrived exactly that way.

I tell that story for one specific reason. At the time, many people mocked me for turning emotion into arithmetic. But a major sports newspaper reprinted my diagram, in which the defensive line was drawn as a distorted trapezoid. From then on I changed how I wrote. I no longer said the back line pushed up 68 metres. I said the back line was like a zip that had burst open all the way to the valve box.

That is how I want to describe the RB20.

The RB20 was not a broken car. It was a car designed to run in a very specific condition, and when that condition changed, the car lost its balance. Like a zip pulled too tight for too long. It keeps its shape. But a small force in the wrong direction and it bursts at the weakest point.

The weakest point of the RB20 was the sidepod region and how it handled airflow at low speed. In slow corners, the car needs mechanical grip from the rear tyres. When the rear tyres are not yet in their optimal temperature range, that grip is not there. And when that grip is not there, the driver is forced to wait. In racing, waiting is a form of losing.

McLaren understood this. And that is why they did not try to beat Red Bull with peak speed. They beat Red Bull by dragging the fight into the zone where their car was strongest: long races, high temperatures, and consecutive slow corners.

This is strategy at the design level, not the race level. And it is why I say McLaren's 2026 title was not decided in Abu Dhabi. It was decided in the design office, over many months, by people the audience never sees on television.

Now I want to address the most counter-intuitive part of the whole story.

The popular narrative of 2026 runs like this: McLaren had the fastest car by the end of the season, but Norris lacked the nerve to take the drivers' title, while Verstappen was good enough to compensate for a weaker car. It is a compelling story, easy to tell, and it contains part of the truth.

But it skips something important: the constructors' championship is a measure of a system, not an individual. And McLaren's system in 2026 was stronger than Red Bull's. Not at one race, but across twenty-four.

Look at the points each team scored over the final ten rounds and you will see that McLaren had almost no genuinely disastrous weekend. They did not win the most in that stretch, but they rarely dropped points for no reason. That is the signature of a mature team. It is also the signature Red Bull lost when they entered their internal crisis.

The counter-intuitive point is this: in a season where car development is capped by a cost limit, maintaining organisational stability matters more than having a brilliant engineering idea. You can have the best idea in the paddock. But if you cannot get it onto the car at the right time, at the right race, that idea is just a note in a document.

I have a line I use fairly often when analysing transfers: a contract only looks good on paper when nobody has tried to fit it into a running system. That is true of drivers. It is also true of technical upgrades. An upgrade package only has value when it is fitted into a system capable of exploiting it. If that system is in disarray, even the best package becomes an uncontrolled variable.

That is what happened to Red Bull in the second half of 2026. They brought upgrades. But those upgrades did not create a gap. They only added more variables for the engineers to manage, while the team's mental resources were already fragmented.

On the other side, McLaren did the opposite. They brought fewer upgrades, but each was integrated carefully. More importantly, they kept an organisational structure stable throughout the season. That was the foundation that let them exploit their rivals' mistakes.

In elite sport, exploiting a rival's mistake is not luck. It is a skill. And that skill requires a system solid enough not to make its own mistakes while waiting for the rival to make one.

There is one more dimension I want to touch on, though it is less about engineering. It is the grandstand.

The 2026 season saw crowds return in force to the circuits, but it also saw something else: media pressure on young drivers rising faster than ever. Every mistake is analysed, magnified and circulated within minutes. For a driver in the middle of a first title push, that creates a kind of pressure no metric can capture.

An empty grandstand does not kill a race, but it takes away something no metric can measure. That holds in both directions. A packed grandstand can also generate pressure no metric can measure. And that pressure does not distinguish between a rookie and a veteran.

Norris had to learn to live with that kind of pressure in 2026. Verstappen had learned it years earlier. It is a psychological variable, but it has very concrete technical expressions: the quality of the start, decisiveness in overtaking, and the ability to stay calm under attack in the closing laps.

And this is where I want to return to an observation I have kept throughout this piece.

There is a field I have followed for many years, and it has taught me a great deal about how a phase of a career can be destroyed by haste itself. That field is injury and return. I have watched many athletes come back too soon after a ligament injury, and I have come to see that the psychological fear is far harder to repair than the body. The body can recover on a schedule. Belief in your own body has no schedule at all.

This connects directly to Norris's story, and to any young driver entering a title fight. A mistake at a start is not only a technical mistake. It is a psychological trace that gets recorded. And that trace can affect the next start, and the one after that, in a loop that can only be broken by a genuinely positive result.

Norris broke that loop at Zandvoort, winning by 22.9 seconds over Verstappen. That is the race I opened this piece with. And it is why I chose it as the starting point rather than Abu Dhabi.

At Abu Dhabi, the constructors' title was already all but mathematically settled before the race began. The result there was a consequence. Zandvoort was the cause. It was the race where McLaren proved they did not merely have a fast car, but a system capable of turning speed into results reliably.

There is a small detail at Zandvoort I consider important. Throughout that race, McLaren did not need to make a single genuinely risky strategy call. They pitted inside the correct window. They chose the right compound. They held a safe margin. A win by 22.9 seconds is not a lucky win. It is a win the team controlled from the first lap to the last.

And this is what I want to emphasise in closing.

The difference between a fast team and a championship team is not peak speed. It is the ability to control the variables the team does not create: weather, safety cars, collisions, and the stewards' decisions. These variables appear in no forecasting model. But they appear at every race.

McLaren handled those variables better than Red Bull in 2026. That is the whole story, compressed. There is nothing mystical here. There is no engineering miracle. There is only a system built solid enough to withstand what a 24-race season throws at it.

On Red Bull's side, I believe it will take them some time to rebuild their structure. A car can be fixed in one winter. A fragmented decision-making system needs more than that. And while they fix it, the other teams will not wait.

For McLaren, their challenge next season will be entirely different. When you are the hunted team, you must defend a position. When you are the hunter, you are allowed to take risks. Those two states demand two different kinds of discipline. And the history of this sport shows plenty of teams who won a title once and could not win a second, not because they got slower, but because they could not change how they operated.

This is the question I will be tracking in the opening rounds of next season: can McLaren keep the calm of a hunting team, when everyone is looking at them as champions?

And for those reading this, I want to leave one thought. When you watch a race and see a car win by a big margin, ask yourself a question: where was that margin created? On the track, in the strategy room, or in a design office thousands of kilometres away, months earlier?

The answer usually lies where the television cameras do not point. And that is where I will keep looking, race after race.
