F1 Decoded: Inside the 2026 Regulation Reset

Formula 1 enters a new era in 2026. We deep-dive into the new regulations, unpacking the rationale and thinking behind the changes—and what they mean for teams, drivers, and the future of the sport. 

Transcript

SPEAKER_01 0:06

Welcome to F1 Decoded, the podcast that breaks down the world of Formula One from the technology behind the cars to the strategy on race day and the rules that shape the sport. We unpack everything that makes F1 tick. Whether you're new to the grid or a longtime fan wanting a clearer view of what's really going on, this is where the sport gets decoded. Today we're taking a closer look at the 2026 regulation reset. So let's get it going. Welcome to Boxbox to Box, your F1 podcast. Let's. I kinda remember Mohawk used to say, authoritative news source. Was that the one? That's correct. Well we're back. We're back for 2026. We're here to talk about the regs that have changed uh and just give everyone an idea about what's upcoming in the new season. So um is there anything you want to just touch on Moha before I start shooting your questions?

SPEAKER_00 1:01

No, it's it's how we had decided to do this because there's quite a it's the first time in a long time where there's going to be quite significant changes to the regs and the whole new era, I think, is dawning. So we thought we'll try and uh demystify this for the listeners to some extent.

SPEAKER_01 1:14

Sounds good. So let's jump in. The 2026 regulations mark a bold shift towards sustainability and closed erasing, uh building on the 2022 ground effects rules. What's inspired the FIA to overhaul both chassis and power units simultaneously?

SPEAKER_00 1:31

Um the FIA is looking to, as part of these rule changes, is looking to sort of showcase a balance between what is cutting-edge technology, uh, but also sort of minimizing the environmental impact. So uh in terms of sort of sustainability goals, they are uh looking to reduce carbon emissions as they work towards that uh 2030 goal of net zero. Um, the 2026 power units will run on 100% sustainable fuel. And the cars are designed to be overall uh more efficient than they were in the preceding years. Part of these rule changes also is to encourage closer racing between the teams and the drivers, particularly with uh having a manual override mode and an on-demand burst of battery power for the overtake as opposed to the DRS system that existed previously. Uh overall, there is going to be an increased electrical power, of sort of a 50-50 split between the internal combustion and the electric power. And the battery element itself, the output is going to increase by 300% to about 350 kilowatts. So, overall, I think they're looking at what they consider to be a nimble car concept. The cars that are lighter, faster, more agile, they'll have reduced dimensions, shorter wheelbase, narrower widths, and as a result, they're actually going to be lighter cars as well. What this is also working towards is hopefully attracting new manufacturers to the race, basically, and to the and to the sport to make the championship more attractive to new to new manufacturers, but also to existing competitors as well, while promoting both sustainability and safety in the sport.

SPEAKER_01 3:11

Yeah, so the new power units they eliminate the MGUH and they boost the MGUK output to 350 kilowatts for a 50-50 split, uh, as you said, uh with the internal combustion engine. What does this change enhance? Oh, sorry, how does this change enhance F1's road relevance?

SPEAKER_00 3:30

So the intent with the with the changes here is actually to make it closer to uh road cars and how they behave. The increased electrical power, which is I think nearly three times uh the capacity of what it was previously, is intended to bring it closer to the current road car hybrid systems. It sort of leads to faster acceleration and better overtaking capabilities. The MGUK design itself is meant to be a more simplified design compared to the the previous MBUH, MGUH design, where it's a lot more efficient at recovering energy and then deploying that recovered energy as well. And it is expected that this might actually lead to overall more reliability in the power units so that there are less uh breakdowns, less instance of the power units actually dying. This combined with uh sustainable fuels and overall battery technology advancements will eventually translate to road cars. And I think Fayette's intent is to try and bring we had got to a point where Formula One cars had gone so far away from road cars, and I think this is uh a gradual transition to bring it more relevant towards road cars.

SPEAKER_01 4:42

Yeah, and I I I do wonder, uh I'm not sure if you can answer this question or not. I do wonder when uh the the F1 cars will have uh enough reliance on the the battery side that they'll get instant torque like uh like Formula E cars have, which is pretty much their advantage. So um tell me, Mohan, uh uh fully sustainable fuels uh derived from non-food sources or um municipal waste debut in 2026. Uh how will this shift to net zero carbon emissions? Sorry, start again. How will how will this shift to net zero carbon emissions impact teams like Alpine, now a Mercedes customer?

SPEAKER_00 5:23

They had, as far as I know I know, uh they have partnered with uh Eni, ENI, uh who is the new energy and fuel supplier for the the 2025 season. They that replaces a castrol and BP for that team. Um this sort of allows them to adapt to the to the new fuel regulations. The intent, I guess, with the sustainable fuels is for it to be derived from uh non-food sources and municipal waste as well is intended to then as a result uh reduce the overall carbon footprint as well. Um and and and as I mentioned before, moving towards that net zero target of in 2030. Um the partnership that Alpine has developed with Any goes beyond their fuel supply as well. Um and they intend to work together with them in terms of electric mobility infrastructure, smart mobility devices, and things like that as well. Overall, it is it is intended to sort of drive innovation and sort of advancements in engine technology and to lead to more efficient powertrains, I guess, in these vehicles, but at the same time keeping an eye on what the environmental impact is and try and minimize that impact.

SPEAKER_01 6:35

Yeah, so the active aerodynamics replaced the DRS with X mode for X mode for low drag straights and Z mode for high downforce corners. This does sound very formula E-esque. Uh how will this system reshape racing strategies at tracks like Monza, for example?

SPEAKER_00 6:52

The X mode is uh is is designed to allow drivers to sort of reduce the drag on straights so that increases the top speed and enables more efficient sort of acceleration out of the corners. This will actually be particularly beneficial on Monza's long straights. Whereas the Z mode will provide high diet force settings for corners, improving grip and handling. And this will actually allow drivers to carry more speed through turns and maintain better control. I guess part of this also it comes down to how the drivers work between the two modes and how how easily they adapt to those changes. Adjustments also then translate to the dynamic adjustments to the front and rear wings, which actually allows the drivers to optimize their car's performance for different sections of the tracks. It actually brings a lot more control to the driver than existed previously, rather than it actually being preset or being automatic to some extent. And this manual override mode that will that will be there, will provide an on-demand burst of battery power. It'll create new overtaking opportunities, but also it will encourage uh drivers to be conservative in terms of how they manage that battery power as well, because uh the first few races will actually tell us how um how well the drivers have adapted to that responsibility being put in their hands uh to manage that going forward. So um uh as I mentioned at Monza, the drivers will most likely use the X mode on the long straights, uh, but with the Z mode to um be more useful in the corner space.

SPEAKER_01 8:31

Well, the cars will be 30 kilograms lighter with a shorter uh 3,400 millimeter wheelbase and 1900 millimeter width. How do these nimble car changes address driver complaints about bulky chassis?

SPEAKER_00 8:47

The weight obviously reduction has a direct translation to that power to weight ratio, uh, and that'll be an immediate impact and and uh converts to the to the agility of the car itself. The shorter wheelbase and the narrow width of the cars itself, I think translates to the responsiveness of the car to what the driver wants to do. I understand the width of the flow has been cut as well by something like 150 millimeters, if I remember correctly. And so what it actually means is it would make these cars a lot easier to handle for the drivers. And what that actually what that translates to, it actually reduces the physical demands on the drivers so that they can then focus on racing itself so that those strains that they previously were going through would be reduced to some extent because the cars are more agile and more responsive to what they actually want to do, and also provides the drivers with better feedback in terms of how the car is performing. Um so as much as these drivers enjoy driving these cars, I think it actually will make it more enjoyable for them and more rewarding for them overall as well.

SPEAKER_01 9:52

Do you actually think that these will have a noticeable change? Like in some ways, in some ways, I kind of I question if this is like a vacuous truth with how much the reduction has been. Because there is obviously a reduction in weight there and there's a reduction in the size of the car. But is it is it enough that it will actually be noticeable from a racing perspective?

SPEAKER_00 10:11

I think initially, definitely, because part of it would translate to how the drivers adapt to the changes and how quickly they adapt to the changes. And also how they use, as I said before, these responsibilities that have now been put in their hands to manage their car, to manage the batteries and many and how they how the cars are handling. So I think there will be some initial teething problems in terms of getting the drivers getting used to this. But the rules are the same for everyone. And it comes down to those fine margins where teams start playing within to try and gain advantages across across and how they can get creative, I guess, within those boundaries to make to exploit those rules and the and the and the tolerances that are allowed within those rules to gain an advantage on the other teams.

SPEAKER_01 10:58

Good answer. Now, the 2026 rules reduce downforce by 15% and drag by 55% with partially flat floors to curb porpoising, uh, which was an issue. How will this help midfield teams like Haas close the gap to leaders?

SPEAKER_00 11:14

The reduction in the downforce um is expected to make the cars less sensitive to the aerodynamic disturbances, I guess. But that fundamentally is expected to allow the midfield teams to catch up a bit more to the leading to the leading teams. And also I think it would make the cars a little bit easier to drive and more forgiving than they have been in the past. Reduction in the drag that is expected will increase the efficiency of the car in both fuel management and current management so that less energy is wasted, uh, allows it to accelerate faster and to maintain speed more efficiently. And I think the the aerodynamics being somewhat simplified, it reduces the complexity in the development of the aerodynamics as well as a result of that. And so this would allow midfield teams like Haas, for instance, to compete more effectively with the top flames and brings that playing field a little bit more level. I mean, there is still a vast difference between the top teams and the bottom teams, but I think it's it's it's trying to even that playing field a little bit more. But also we have talked in the past where drivers at the back of the grid, if you put them in a in a McLaren for argument's sake, how well they would do. This would be a good opportunity to actually see how much emphasis there is actually on the driver's skills, so that these changes even up the playing field from a car point of view and it allows the actual driving skills of these other drivers to shine.

SPEAKER_01 12:47

Can you explain what porpoising is for anyone that doesn't know?

SPEAKER_00 12:52

Fundamentally, I think it is when there is too much down force on the car so that it is, uh I guess, as far as I understand it, the downforce is obviously forcing the car down as low as possible. But at some point in the corners, that actually has to release. And so there is this constant up and down adjustment of the downforce so that the cars actually are almost bouncing across the track without being able to just be flat on the track all the time. This not just affects the cars, but I've actually seen drivers roll out of cars because of it. It does some serious damages, damage to their backs, and can actually have long-term physical effects on the drivers. So it's a good thing that they are changing this to reduce that, uh, maybe not eliminate altogether, but to reduce it. Uh, because it's not a matter of the damage on the cars, but it's also protecting the drivers to some extent. And why is it called porpoising? Because it basically, when you look at it in slow motion, it looks like a porpoise jumping in and out of water, right? It does that the leap out and the and the dive underneath, it's that curve that happens, I guess. So the front and the back are flipping like a porpoise out of water.

SPEAKER_01 14:02

Yeah, yeah. Not to not to not to move into an Animal Planet type podcast. Um, different different to a dolphin as well. So um I thought I thought I'd ask a question. Uh so um uh look, safety upgrades uh include a two-stage front impact structure and strong roll hoops. Uh how do these changes build on lessons from past incidents like um Guang Yu Zhou's uh 2022 Silverstone crash?

SPEAKER_00 14:27

So overall, um, this is intended to improve the crashworthiness of these cars. So the two-stage front impact structure is designed to absorb and distribute those forces of an impact more effectively. And so thereby it sort of reduces all the risk of damage to the survival cell and in turn the injury and injuries to the driver. That crash of Jogon News informed this a lot, basically. And where the car structure played such a critical part in protecting him, where in previous years it probably wouldn't have. So that that led to one of the changes came out of that particular crash. The roll hoop, the strength of the roll hoop has been increased a lot. And this is obviously to better withstand uh an event of a rollover or an impact, uh, and also reduce any risk of structural failure and protecting the driver's head and helmet at the same time. So this is sort of moving to the next level of safety that having learned from that particular crash, and what can be improved from that. Um, and generally, FIA, as they work through these changes, are obviously trying to increase the safety margins of these cars year by year. And so the front impact structure, the roll hoops, all of that, I guess, is is it's a general progression as they learn from unfortunately they learn this from crashes of things that could be improved. And we've this been a history of changes coming in, all the way back to you, no, Senna's crash, for instance, of changes that have been brought into safety because of it.

SPEAKER_01 15:59

And now the the manual override, bro, the manual override mode uh offers trailing drivers a 350 kilowatt boost up to 337 kilometers per hour. Um it has sparked debate. How will this system enhance overtaking compared to the DRS system?

SPEAKER_00 16:17

Uh the first thing, as I mentioned before, this puts the responsibility directly in the hands of the drivers. So obviously, they have the opportunity to use that override anywhere on the track that they see fit. And it's also expected that that will provide more opportunities for overtake on these tracks, not just in the DRS zones that was previously available. Um I think something like a 350 kilowatt boost is expected out of these new power units. But as much as putting the responsibility in the drivers, it actually becomes quite strategic of when these drivers will actually use it. So drivers will learn track by track where the best place to use this would be. And it's a learning process for them as much as anything else. And it actually makes it overall from a team point of view, it becomes tactical and somewhat unpredictable, which is great from great from a race point of view. And from a from a fan point of view, I guess you think it leads to more exciting and unpredictable racing. So I'm certainly looking forward to seeing how this works, particularly in the first few races and how the drivers actually use this. And it's overall like intended to showcase the skill of the drivers.

SPEAKER_01 17:25

Yeah, and there's so next season, six power unit manufacturers, Ferrari, Mercedes, Honda, Audi, Red Bull Ford, and Alpine commit to 2026 with Cadillac joining as an 11th team. Now, how would the shake up the grid?

SPEAKER_00 17:41

So the first thing I guess it does is it um it brings in uh additional competition. And obviously, with the focus on sustainability and uh improvement of the electric, electric part of the power unit, the manufacturers themselves will need to adapt to those rules fairly quickly. They have been in the in the preceding uh year as well. This overall will obviously lead to advancements in in overall hybrid engine technology and and and the generation of sustainable fuels. What will be interesting to see is the new alliances that come out of these regulation changes, particularly with teams that have changed engines or power units in this time. As I mentioned before, the team that's expected to benefit the most out of this is Mercedes because they will have their engines or a version of the engines in four teams, including their own. The introduction of Cadillac and how they will perform, the introduction of Audi and how they will perform, the departure of Honda from Red Bull to Jason Martin, and also the partnership of Red Bull with Ford. All of this, I think, is a significant shake-up, and probably the most significant shakeup in recent times that we've seen in terms of engine manufacturers. But as I mentioned earlier, what this actually does also is the shakeup in the rules and also the rearrangement of these engines, it could, it could lead to more manufacturers wanting to join the grid and also or supporting them or providing technology for these cars. So overall, I think it'd be interesting to see how the teams that have actually had a change in power unit settle in. And for instance, will Honda fare better in an Aston Martin versus the Red Bull? Um, or would the Red Bull Ford be uh a far superior engine? Will Mercedes-Benz actually learn from all of the cars that they have got their uh engines in and exploit that to the full extent? So it'd be interesting to see what the impact's going to be from all these changes.

SPEAKER_01 19:39

Yeah, so Christian Horner, who was with Red Bull at the time, uh, criticized the early 2026 drafts, fearing an engine formula. How have chassis tweaks balanced these concerns for teams like Red Bull?

SPEAKER_00 19:53

The I guess this the changes are they intended to create a more balanced sort of competition between the engine and chassis performance. So the reduced downforce, the reduced drag, the increased emphasis on electrical power will actually force teams to try and optimize both the engines and the chassis setups. This nimble car concept that is that is mentioned. It'll overall make the cars more agile, make them more responsible. So that it'll actually allow teams to focus more on the setup and the handling rather than solely relying on engine power as such. The reduced downforce and drag will make the cars less sensitive to sort of the disturbance, as mentioned before, less sensitive to or less reason for purposing. Um, and allows again the teams to focus on the performance of the chassis and also the driver's skill. Um and the drivers themselves get an opportunity to shine to showcase their actual skills in in terms of managing um these changes and adapting to these changes. Um and it it all of these all at every time there is change, what it brings with it is opportunity. So all these teams, it brings with them a great opportunity to try and exploit these changes uh and and produce the best possible car that they can.

SPEAKER_01 21:12

And can you explain what an engine formula is? This is like just complete engine dominance that was being discussed there.

SPEAKER_00 21:19

Um I guess part of it is that um in previous years and particularly in uh relating to Christian Horner's comment is the fact that I think there was a feeling that um the aerodynamics didn't play as significant part as the engine did in terms of the the key the teams, particular teams up the further up the grid. So that they having uh having a good engine, the focus on being having a on having a better engine, um, there was a larger focus on that aspect than than adjusting the aerodynamics of the car. So I think these changes forced them to look at both those aspects and takes away from just having the best engine on the grid. So this is That's kind of what happened in 2014, is that right? That's right. Yeah, that's right. So this I think overall Yeah. So overall, I think it is it is for the sport itself, it is great because it um, as I mentioned before, it also gives those midfield teams an opportunity to try and bridge that gap a bit more uh by being clever with their setups basically as well.

SPEAKER_01 22:22

And is that definitely more of a concern for a team like Red Bull where they don't make their own engines?

SPEAKER_00 22:27

Uh yes, definitely. So where they're relying on on another party to actually to manufacture that. So they're um at the mercy of the manufacturer, whatever they're being given from that manufacturer. So I guess for this team like them to now take that in-house a bit more, they have a bit more say and a bit more authority to to dictate what how these engines are produced.

SPEAKER_01 22:48

And other teams, I guess like uh um stake, for example, face uh massive investments to prepare for 2026. Um 2026 is active aero and new power units. How are smaller teams adapting their facilities and budgets to stay competitive?

SPEAKER_00 23:06

So, from what I understand, is there, I mean, there's there's significant investment um in this new technology and infrastructure to sort of to accommodate these the active aerodynamics and the new power unit regulations. I guess teams have to manage their budgets carefully, and they actually, as part of that, they actually have to prioritize what aspect they developed within the cars. Opting to to source an external power unit is actually meant to be more cost-effective than developing something in-house. And so the teams that that don't have as much money or backing behind them would opt to get a third-party engine in that sense rather than rather than at this stage developing their own. Um, and in the long term, these partnerships that are being formed as well, for instance, the Red Bull and Ford Partnership. It'll be interesting to see what comes out of that and how effectively that actually works, versus having a dedicated Red Bull engine for argument's sake. Um, and um these are the things that we'll be looking to see what comes out of this and how this actually evolves over the season. Because the intent, I guess, is these new changes, the new power units that are coming out, the overall cost of them is going to be a lot higher than it was in 2025 because of the changes, because of the technology. So it's down to teams to say, well, how do we manage our budgets? To to make sure that one, we're not exceeding them, uh, and two, that we remain competitive on the grid.

SPEAKER_01 24:34

And that these these lower teams that they lower down the standings, do they still get the the increased wind tunnel time to try and even out things?

SPEAKER_00 24:42

I think so, but I think also uh there is a I'm I'm not entirely sure of the how the breakdown actually happens, but I think um there is a there is a adjustment based on where the standings are in the previous year as well, in terms of how um how much wind tunnel is is given. Um, just so that uh the the lesser teams are not disadvantaged compared to the teams at the top of the grid in that sense.

SPEAKER_01 25:11

Uh the skid block's role in 2026 remains unclear with alternative materials proposed after the 2024 grass fires. Could its evolution redefine ground effect cars? And and has this been locked in, by the way? Is there been any recent changes that have sorted this out?

SPEAKER_00 25:26

It nothing's actually been locked in, but it's certainly something that's actually been considered. And and as you mentioned before, because of uh the sparks that are generated from uh from the skid blocks and and the risk that that brings with it. So they're sort of looking at um changing from um titanium to steel because the steel is less likely to create that, but uh the problem is steel is three times as heavy as titanium. So there is the balance of that in that sense, of how that is actually managed. So nothing's seriously locked in at this stage, but it's it's another thing that's evolving within the sport, and to look at how they balance out risk versus performance as such.

SPEAKER_01 26:08

Also, just the spectacle of the whole thing. We're talking about like unintentional pyrotechnics here, it's it's probably one of the most spectacular parts of the ball of effort.

SPEAKER_00 26:16

If you look at um what happened in the um the Las Vegas race in 2025, and there was already discussion that McLaren were running their car way too low, given how much Oscar's car was sparking, basically. Um as a fan, you could actually see that they were, they had made a they had made a significant adjustment to their ride heights, uh, and it was showing up. But as yeah, just to see it on track, and particularly for a a night race like the one that you see and on a street track, it is pretty spectacular to actually see. But from a sport point of view, they have to manage that fine line between risk and spectacle.

SPEAKER_01 26:56

Yeah, and they they I guess they always do in a sense. So no, fair enough, Mohan. Uh so look, that kind of covers off all the things we want to touch on today. Is there anything else we want to discuss um just with this upcoming season moving forward?

SPEAKER_00 27:09

Yeah, so there are a couple of other things. I guess this is more um from a race management point of view, obviously, and I mentioned it in the in the 2025 closeout as well. So we still maintain 24 races this year, but um we lose uh Imala, and that was talked of uh previously, uh, because I think that track is no longer suitable to uh the current cars or even the cars that are coming up in 2026. But however, do we do gain Madrid uh in the middle of the season? Uh, and that'll be a home race for Sainz and Alonso. And it's something I think most race fans are looking forward to that uh to that race as well. But the other thing that's actually quite significant is because there will be two more cars on the grid, they have had to make an adjustment to qualifying uh with Q1, Q2, and Q3. Previously, with Q1 and Q2, the bottom five cars get dropped out, but now the bottom six cars will get dropped out in each of Q1 and Q2, so that when they get to Q3, there will be still only 10 cars left competing for Q for pole position. So some of these changes that that actually been brought in to try and even things out, I guess. But overall, um, I think this is a greatly anticipated set of changes and also significant amount of responsibility being placed in the drivers' hands of how they handle these cars. I think, I think calls for and will showcase some amazing racing. And the drivers and the teams that manage those changes well and exploit them to some extent as well, will do the Do you want to uh uh mention all our socials, Mohan? Uh we have our website is boxboxbox.net.au, which will also take you to our Facebook and Instagram and Twitter accounts. So we will keep you abreast of any changes, any uh episodes that are coming up. And as mentioned previously, we are looking to rework the format for this year. In addition to looking at race weekends, we also uh want to look at some classic races and also do a deeper dive into uh technical aspects of Formula One racing, like we are doing here. So that if you have any topics that you would like us to investigate, to review, to discuss, or if you have any questions, please send it through to info at boxboxbox.net.au and we will certainly address them.

SPEAKER_01 29:28

That's right. And since we've only just started setting up the socials, we have zero traffic. If you want to reach us, if you want to reach us, you definitely will be able to. Absolutely. That's all right. Number one customer. All right, no worries. All good, Mohan. Thank you for your time. And uh look forward to uh covering this entire year with you. Excellent, thank you.
