Unpacking Norris's "chaos" theory over F1 2026 rules

It is a truism of motor racing that the best driver in the best car is most likely to win the world championship. There are exceptions that prove the rule, such as the titles Jim Clark missed on account of Lotus's fragility, but the list of unimpressive or undeserving champions is a short and debatable one.

Among the consequences of Formula 1 shifting to narrower cars and tyres, and power units with a roughly 50-50 split of internal combustion power to electrical output, is that driver ability will have a more powerful effect on how races – and ultimately the championship – will pan out.

With less downforce the cars will be slower around corners, but the torque available from the electric motors will give a powerful punch along the straights, augmented by the active aerodynamics. But while the capacity of the electric motor to harvest energy has increased roughly three-fold, the batteries remain the same so they will be depleted more quickly and need to be recharged around the lap.

That's why Lando Norris used the word "chaotic" when referring to how the new rules will affect the racing.

Firstly there is an element of peril in qualifying, since drivers will also have to manage electrical deployment on their prep laps to avoid running out of power on push laps. Lift-and-coast makes for an unhappy bedfellow with the process of bringing tyres up to their optimum temperature.

And even if grids aren't disrupted by drivers getting that balance wrong in qualifying, in the race many of them will be making different choices at different times in terms of when to deploy and when to harvest. Strategies will have to evolve on the fly, even more so than in previous years, because track position may be less easy to defend – so race outcomes are less likely to be determined by drivers "occupying the crease" to use cricket parlance.

During an audience with Norris at the McLaren Technology Centre this week, Autosport took the opportunity to ask the world champion how much more important the role of the driver is going to be in terms of dictating race outcomes, since racing will no longer be a question of driving to the limit of available grip at each corner.

"At the minute I certainly think there's a bit more emphasis on how the driver can handle and control all of these things, both in just a qualifying lap but also in the racing situations," he said. "I think it's going to be more complicated to understand, like how do you prepare overtakes?

"Before it was pretty simple in terms of, you drive as quickly as possible, but avoiding the dirty air, and it was quite easy to build up the battery in a good way, in an efficient way. Now when you save battery you're going to lose quite a bit of time, and you're going to lose a lot on the straights.

"You'll see more yo-yoing, more moves with extra speed, but then that person might have to defend more than what you've seen in the past, and that will create more chaos" Lando Norris

"So, just understanding all of these things, a lot of it is down to engineering and calculations, but then the drivers generally still have to do the job on track of actually applying all of these things. So I think you're going to see more chaos in races where a driver has to be a little bit more on top of all of these different situations that can happen – and that will happen through the whole year I would say. I think there's more emphasis on drivers' ability to control all of these things."

Chaos theory

What is less predictable is how each driver will make those choices, and on their individual appreciation of the consequences – for instance, in terms of how much harvesting they will have to do if they choose to use maximum boost. Autosport understands that while the drivers have broadly been impressed by the power available in maximum boost mode, both in the sim and through practical experience during the Barcelona shakedown, they are less pleased by how the cars perform while harvesting.

"You'll see more yo-yoing, more moves with extra speed, but then that person might have to defend more than what you've seen in the past, and that will create more chaos, which is great for you guys [the viewers]," concluded Norris.

But how will this work in practice? Mercedes' Andrea Kimi Antonelli likened the 'new' racing to "speed chess", since there will be a strong element of strategy behind the choices of when to use the boost and when to harvest. It will also vary from track to track based on individual circuit configurations – the balance of corner speeds, how much braking is done, etc.

It can't be done at the track

In the long term, strategies for each track will converge based on data and experience. But in the immediate future the drivers and engineers face a much greater workload before they arrive at the track.

There will be more intensive discussions and a greater amount of track-specific sim evaluation to determine the optimum balance of deployment and recovery ahead of each event. This will be a necessary process for preparing the driver for what's required and minimising the number of angst-ridden radio messages; there simply isn't the track time available to do this and all the other prep work, particularly at sprint weekends.

"I think there's certainly going to have to be more effort," said Norris. "Even more effort from the sim team themselves, but there's also going to have to be quite a bit more time spent as drivers. Everyone on the grid is going to spend more time, more focus on simulator time to understand all of these things – knowing your lift points, how the batteries are going to work in racing situations, where you can deploy or you don't want to deploy, what are the consequences in every corner.

"Especially when you go to sprint races and things, you're not going to have the time to understand everything you need to be able to do, which only puts more importance on simulator time.

The chances are some drivers will depart from the script in a racing situation – they won't be able to help themselves, like a cat chasing the output of a laser pointer

"So, I've already done a good amount – I mean, for the next two days, I'm basically just doing simulator, so I'll be sitting at a screen for a lot of time. But, yeah, I'm sure everyone's going to say the importance of sim time for the race drivers is going to go up, but there's more effort and emphasis on getting it as accurate as possible at the same time."

Despite all this preparation, the chances are some drivers will depart from the script in a racing situation – they won't be able to help themselves, like a cat chasing the output of a laser pointer. The situation is complicated by the absence of visual cues; flashing red lights on the cars will signal harvesting, as before, but until the ruleset matures the drivers will not necessarily know what their rivals are doing.

It may settle down with time and experience, but the opening races are likely to expose weaknesses in preparation, discipline and mental bandwidth. Viewers, commentators and pundits may also struggle to decode exactly what is happening at any given time unless F1 is able to facilitate useful graphics (as opposed to the largely useless AWS-branded fictions which have garlanded our screens of late).

Is 'chaos' the right term? Perhaps not, but the likelihood is the opening grands prix of this season could become unruly…
