SIG-1000	2026-02-09	Adrian Newey	Team leadership	Noncommittal	Spectacle and entertainment	It could be something similar here. Newey said the 2022 rules only briefly made overtaking easier and the 2026 rules could turn out similarly.	The Race Supplementary
SIG-1001	2026-02-10	Fernando Alonso	Driver	Mixed	Driver skill and sporting purity, Fairness	There are a couple of things that are really probably over-regulated. Alonso said teams' preparation and FIA restrictions on energy use leave drivers little freedom to make a difference, that older cars gave more adrenaline, and that the new F1 is different, not clearly better or worse.	The Race Supplementary
SIG-1002	2026-02-10	Lance Stroll	Driver	Critical	Driver skill and sporting purity, Road relevance and sustainability	it would be nice to have normally aspirated engines with synthetic fuels Stroll said he has long preferred naturally aspirated engines with synthetic fuels, that he does not make the rules, and that a winning driver would not mind downshifting and lifting on the straights.	The Race Supplementary
SIG-1003	2026-02-11	Toto Wolff	Manufacturer	Noncommittal	Competitive balance, Fairness, Innovation and competitiveness	that could be quite damaging for the performance On the compression-ratio dispute, Wolff said Mercedes kept the FIA informed and had assurances its engine complied, said rivals lobbied the FIA, and warned that rules invented on the fly to level the field would undermine engineering freedom.	Sky Sports Supplementary
SIG-1004	2026-02-11	Lewis Hamilton	Driver	Critical	Spectacle and entertainment, Driver skill and sporting purity	None of the fans will understand it, I think After his first morning of testing, Hamilton said energy management is ridiculously complex and fans will not understand it, though managing it is straightforward; he described self-learning deployment algorithms and very low gears used to recover energy.	Motorsport.com Supplementary
SIG-1005	2026-02-12	Max Verstappen	Driver	Critical	Driver skill and sporting purity, Spectacle and entertainment	It feels a bit more like Formula E on steroids. After the first test days in Bahrain, Verstappen said the cars are not much fun to drive, that energy management means drivers cannot drive flat out, and that much of the rules feel anti-racing, though the car's proportions look good.	Motorsport.com Supplementary
SIG-1006	2026-02-13	Fernando Alonso	Driver	Mixed	Driver skill and sporting purity	The chef can drive the car in Turn 12 at that speed. Alonso said Bahrain's Turn 12, once a test of driver skill, is now taken about 50 km/h slower to save energy, but added that F1 has always been dictated by something, previously downforce, now energy.	RacingNews365 Supplementary
SIG-1102	2026-02-13	Andrea Stella	Team leadership	Critical	Safety, Feasibility and implementation	This may not be an ideal situation when you follow closely At the end of the first Bahrain test, Stella called for rule changes before Australia on safety grounds: the race start procedure should let every car have its power unit ready, and cars slowing suddenly to harvest energy while others follow closely could cause accidents like those of Webber and Patrese. He said safety on the grid outweighs competitive interest and could be achieved with a simple adjustment.	The Race Supplementary
SIG-1007	2026-02-16	George Russell	Driver	Mixed	Driver skill and sporting purity, Feasibility and implementation	the one thing which is quite annoying and isn't that intuitive Russell said using very low gears in corners to keep the turbo spinning is annoying and unintuitive because the car is not designed for it, but praised the power available and expected progress.	RacingNews365 Supplementary
SIG-1008	2026-02-17	Dan Towriss	Manufacturer	Noncommittal	Feasibility and implementation	We're really following the conversation on the [regulations] closely TWG Motorsports boss Dan Towriss said Cadillac is following the regulations debate closely, that rules might or might not change before 2031, and that the GM power unit target remains 2029.	Formula1.com Supplementary
SIG-1009	2026-02-17	Lando Norris	Driver	Defends	Driver skill and sporting purity	A lot of fun, I really enjoyed it Norris said the 2026 car is the most different he has driven, with less grip and more power, harder to drive but more fun.	Motorsport.com Supplementary
SIG-1010	2026-02-17	Charles Leclerc	Driver	Mixed	Driver skill and sporting purity, Innovation and competitiveness	I find the fun in a different way Leclerc said the car is not the most fun he has driven but he enjoys the challenge of developing the new system and thinking outside the box.	Motorsport.com Supplementary
SIG-1011	2026-02-17	Andrea Kimi Antonelli	Driver	Defends	Driver skill and sporting purity	It's a lot different, but I've been quite enjoying the car Antonelli said the lighter, shorter car is more agile and nice to drive, though traction on long runs is tricky.	Motorsport.com Supplementary
SIG-1012	2026-02-17	Pierre Gasly	Driver	Noncommittal	Stability and patience	I'm more going with an open mind into the season Gasly declined to take sides between Verstappen and Norris, said he would keep an open mind and give the cars time, expecting fast development as in 2014.	Motorsport.com Supplementary
SIG-1013	2026-02-17	Esteban Ocon	Driver	Noncommittal	Stability and patience, Spectacle and entertainment	at the moment it's too early to say that Ocon said the car may not be the most fun but the new challenge is interesting, and whether it promotes overtaking and the show remains to be seen.	Motorsport.com Supplementary
SIG-1014	2026-02-17	Valtteri Bottas	Driver	Defends	Driver skill and sporting purity	But I like it. It's fun. More sliding. Bottas said the cars feel like 2014-2016 cars with less downforce and strong power out of corners, and that he likes driving them.	Motorsport.com Supplementary
SIG-1015	2026-02-18	FIA (institutional)	FIA	Defends	Stability and patience, Feasibility and implementation	no immediate major regulatory changes were required The F1 Commission, chaired by Tombazis and Domenicali, agreed refinements, reported positive driver feedback on weight, size, ride and acceleration, and decided no immediate major changes were needed because evidence was immature and early change risked instability. Energy management and the race start procedure would be evaluated further at the second Bahrain test.	FIA (fia.com) Supplementary
SIG-1016	2026-02-18	FIA (institutional)	FIA	Procedural only	Procedural only	also at a representative operating temperature of 130°C The FIA said it had put to the power unit manufacturers an e-vote proposing that, from 1 August 2026, compression ratio compliance be demonstrated at operating temperature as well as ambient conditions.	FIA (fia.com) Supplementary
SIG-1017	2026-02-18	Max Verstappen	Driver	Critical	Road relevance and sustainability, Institutional trust and accountability	I don't want us to be close to Formula E Verstappen said F1 should stay distinct from Formula E, should not increase battery power and should instead focus on a good engine. Asked about pushback over his criticism, he said he was sharing his opinion and is allowed to do so.	The Race Supplementary
SIG-1018	2026-02-18	Laurent Mekies	Team leadership	Defends	Innovation and competitiveness	that's also what we love: to break through these challenges Mekies said the regulations are a massive challenge for teams, manufacturers and drivers, which is what the team loves, and he expects Verstappen to master them.	The Race Supplementary
SIG-1019	2026-02-20	Stefano Domenicali	Formula One Management	Defends	Stability and patience, Spectacle and entertainment	I don't understand the panic that is going around. After meeting Verstappen at the final Bahrain test, Domenicali said Verstappen cares about F1 and will be part of its future, that new technology requires a different driving style, and that early doubts are normal as with 2014, 2017 and 2021. He said there would be incredible racing and he was not worried.	Sky Sports Supplementary
SIG-1020	2026-02-24	Carlos Sainz	Driver	Mixed	Feasibility and implementation, Spectacle and entertainment	we should stay flexible rather than committed to a certain level Sainz asked the FIA and FOM to stay open-minded, saying the required harvesting and deployment may be exaggerated and energy-hungry tracks like Melbourne or Jeddah could need adjustments to improve the show.	Motorsport.com Supplementary
SIG-1021	2026-02-28	FIA (institutional)	FIA	Noncommittal	Competitive balance, Innovation and competitiveness, Feasibility and implementation	one of the biggest changes in recent memory The FIA said the World Motor Sport Council approved amendments after testing feedback, including a compression-ratio compromise (checked hot and cold from 1 June 2026, operating conditions only from 2027). It said all parties acknowledged collective learnings from testing and early rounds, and energy management checks continued.	FIA (fia.com) Supplementary
SIG-0001	2026-03-05	George Russell	Driver	Defends	Driver skill and sporting purity	the fastest driver will come out on top Russell said many procedures are now more complicated, but the fundamentals are unchanged: drivers still go flat out through corners and the fastest driver will win. He expects the new procedures to become routine within a couple of races.	FIA Backbone
SIG-0002	2026-03-05	Oscar Piastri	Driver	Noncommittal	Driver skill and sporting purity	are not very intuitive, so it takes some getting used to Piastri said car set-up and driving are now optimised around the power unit, and that much of what drivers must learn under the new regulations is not intuitive and needs discipline.	FIA Backbone
SIG-0003	2026-03-05	Lewis Hamilton	Driver	Noncommittal	Spectacle and entertainment, Driver skill and sporting purity	hope that Formula 1 is able to project that to the fans Hamilton said energy deployment is the biggest challenge, varies by track and can require lift and coast on qualifying laps. He said it is the most challenging rule change he has experienced and hoped Formula 1 and commentators would explain it to fans.	FIA Backbone
SIG-0004	2026-03-06	Toto Wolff	Team leadership	Defends	Spectacle and entertainment, Business and economic climate, Stability and patience	So, I'm not worried at all. Asked about the show on Sunday, Wolff pointed to more than 500,000 expected spectators and said that, as with all new regulations, things will be different but he is not worried about the entertainment.	FIA Backbone
SIG-0005	2026-03-06	Adrian Newey	Team leadership	Defends	Stability and patience	somehow it always all rises on the night Newey said new regulations always attract negativity beforehand, but the racing usually turns out well, and he expected the same this time.	FIA Backbone
SIG-0006	2026-03-06	Graeme Lowdon	Team leadership	Defends	Business and economic climate, Spectacle and entertainment	huge level of interest, possibly because of the regulation change Lowdon said the large crowd would get Grand Prix racing on Sunday and that interest is high, possibly because of the regulation change.	FIA Backbone
SIG-1022	2026-03-06	Stefano Domenicali	Formula One Management	Defends	Innovation and competitiveness, Road relevance and sustainability, Driver skill and sporting purity	I think it's wrong in general terms to talk bad On the first practice day in Australia, Domenicali said it is wrong to talk badly about F1, that the best driver will still be fastest, and that the rules were needed to attract manufacturers with sustainable fuel. He said F1 and the FIA are open to changes if something clearly needs fixing.	Motorsport.com (quoting Sky Sports) Supplementary
SIG-0007	2026-03-07	George Russell	Driver	Defends	Driver skill and sporting purity, Spectacle and entertainment	the car regulations for everyone are definitely a step forward Russell said the new cars are hard to drive and hard for some fans to understand, but more agile and fun than last year's cars. He acknowledged mixed views on the regulations as a whole and said the car regulations are a step forward.	FIA Backbone
SIG-0008	2026-03-07	Andrea Kimi Antonelli	Driver	Defends	Driver skill and sporting purity	I think the car itself to drive is very nice Antonelli said the chassis is softer, lighter and more agile than last year's, though it lacks high-speed downforce. He said the power unit side is very tricky but part of the game.	FIA Backbone
SIG-0009	2026-03-07	Isack Hadjar	Driver	Mixed	Driver skill and sporting purity	the chassis is pretty good, and the rest, I'm not a fan Asked whether he enjoys the new cars given their agility and energy harvesting, Hadjar said the chassis is good but he is not a fan of the rest.	FIA Backbone
SIG-0010	2026-03-08	George Russell	Driver	Defends	Stability and patience, Safety, Spectacle and entertainment	I think we should just give it a chance Russell said everyone is quick to criticise and the regulations should be given a chance over more races. He asked the FIA to make the front wing drop less aggressively in Straight Mode, saying it would make racing safer. He suggested Norris's criticism related to McLaren's competitive position.	FIA Backbone
SIG-0011	2026-03-08	Andrea Kimi Antonelli	Driver	Defends	Spectacle and entertainment, Stability and patience	today was much better than what we all anticipated Antonelli said the overtake mode was powerful and created a lot of action, that the race was better than expected, and that drivers should wait a few more races before commenting on the regulations.	FIA Backbone
SIG-0012	2026-03-08	Charles Leclerc	Driver	Noncommittal	Driver skill and sporting purity, Safety	it's a different way to go about racing for sure Leclerc said he partly agreed with waiting before judging. He said racing is now more strategic because each boost activation has a cost, and that battery cut-outs create large speed differences when defending.	FIA Backbone
SIG-0013	2026-03-12	Pierre Gasly	Driver	Mixed	Driver skill and sporting purity, Stability and patience, Spectacle and entertainment	they're fun, they could be more fun Gasly said he enjoys the cars but there are things he would change, and suggested waiting a few races before a conversation with Formula 1. He said starts are currently a lottery dependent on the power unit and that gaining time by lifting off is not part of Formula 1's DNA.	FIA Backbone
SIG-0014	2026-03-12	Esteban Ocon	Driver	Mixed	Driver skill and sporting purity, Spectacle and entertainment, Safety	Can the driver make enough of a difference as a driving style Ocon said the cars feel better in corners and the races had more overtaking, but the driver cannot make enough difference, which he called the current negative. He called Colapinto's near-miss at the start scary and said F2-style starts should not happen.	FIA Backbone
SIG-0015	2026-03-12	Fernando Alonso	Driver	Mixed	Driver skill and sporting purity, Road relevance and sustainability	You use those corners to charge the battery Alonso said he still enjoys driving, but the challenge has changed: corners that once tested drivers' limits are now used to charge the battery. He said he probably prefers the previous era but likes both, and that whether this is the future is unknown.	FIA Backbone
SIG-0016	2026-03-12	Max Verstappen	Driver	Critical	Driver skill and sporting purity, Safety	I don't really enjoy driving the car Verstappen said he does not enjoy driving the car and wishes he had more fun. He said starting with a 0% battery is quite dangerous, that he has had discussions with FOM and the FIA, and that he hopes for a decent improvement as early as next year.	FIA Backbone
SIG-0017	2026-03-12	Alexander Albon	Driver	Noncommittal	Competitive balance, Driver skill and sporting purity	an area which is quite confusing behind the wheel Albon said energy management is still confusing behind the wheel and a large mental overhead. He said teams that build their own engines have more data and better turbo and battery models for simulation.	FIA Backbone
SIG-0018	2026-03-13	Laurent Mekies	Team leadership	Noncommittal	Stability and patience	let's do these first races, let's see what we are getting Mekies said teams, the FIA and Formula 1 met in Bahrain before the season and agreed to see the first races before adjusting, with willingness across the grid to adjust if needed. He said the regulations are the same for everyone and teams will learn, though one may argue whether formation-lap complexity is necessary.	FIA Backbone
SIG-0019	2026-03-13	Jonathan Wheatley	Team leadership	Defends	Stability and patience, Innovation and competitiveness, Institutional trust and accountability	just what an ambitious set of technical regulations this is Wheatley said the FIA is keeping a steady hand and the open discussion between teams and the FIA is encouraging. He called the regulations ambitious and complicated, warned against knee-jerk reactions, and said FIA mechanisms exist to help ensure a level playing field for power units.	FIA Backbone
SIG-0020	2026-03-13	Flavio Briatore	Team leadership	Noncommittal	Stability and patience, Safety	It's very early stage to have a final judgment. Briatore said it is too early to judge the rules and agreed with Mekies and Wheatley. He said if something is found to be a danger to drivers, it needs to be changed with the FIA.	FIA Backbone
SIG-0021	2026-03-14	George Russell	Driver	Defends	Spectacle and entertainment	I don't ever remember Formula 1 being like that Russell said the racing was exciting, like go-kart racing with three or four cars contending. He said formation-lap switch changes are unnecessarily complicated, but did not see the starts as a safety issue.	FIA Backbone
SIG-0022	2026-03-14	Charles Leclerc	Driver	Noncommittal	Competitive balance, Stability and patience	These rules are quite complex Leclerc said the rules are complex and Ferrari cannot yet explain its qualifying-to-race gap to Mercedes. On starts, he said more teams will find fixes and he does not expect it to be a problem for long.	FIA Backbone
SIG-0023	2026-03-14	Lewis Hamilton	Driver	Defends	Spectacle and entertainment, Competitive balance	when we all get off exactly the same it's boring Hamilton said the race was fun and that variable starts are more exciting and not dangerous. He said Mercedes appears to have an extra qualifying mode that Ferrari lacks.	FIA Backbone
SIG-0024	2026-03-14	George Russell	Driver	Defends	Spectacle and entertainment, Stability and patience	we just still need to give it a chance Russell said the overtake mode works in a similar way to DRS and seems to work quite well, that even some critics may now dislike it less, and that the regulations still need a chance. He said the new cars can offer quite good racing.	FIA Backbone
SIG-0025	2026-03-15	Lewis Hamilton	Driver	Defends	Spectacle and entertainment	it's the best racing that I've ever experienced in Formula 1 Hamilton said the cars are easier to follow and the racing was the best he has experienced, comparing it to go-karting. He said the new systems require more study than any previous era.	FIA Backbone
SIG-1023	2026-03-15	Frédéric Vasseur	Manufacturer	Noncommittal	Fairness, Competitive balance	I think at one stage enough is enough Vasseur said Ferrari had warned the FIA a year earlier that the start procedure would be difficult, was told to design the car to the rules, and had already accepted changes that did not help it, so further start-procedure changes should stop.	Sky Sports Supplementary
SIG-0026	2026-03-26	Charles Leclerc	Driver	Mixed	Driver skill and sporting purity, Spectacle and entertainment	I think in qualifying it's not the most fun I've had Leclerc said he was sceptical before the season but has been positively surprised by the racing, while some overtakes are artificial. He said qualifying is about management rather than a flat-out push, a small throttle lift can cost half a second, and changes are going in the right direction.	FIA Backbone
SIG-0027	2026-03-26	Franco Colapinto	Driver	Defends	Spectacle and entertainment, Stability and patience	It didn't feel too artificial. Colapinto said the China race was fun, following is better than last year, and overtakes were mostly on the limit rather than artificial. He said there are areas to improve, the sport is looking at them, and it is early to judge.	FIA Backbone
SIG-0028	2026-03-26	Lando Norris	Driver	Mixed	Driver skill and sporting purity, Spectacle and entertainment, Stability and patience	you're just a complete passenger and you can't do anything Norris said the racing looks good on TV and viewers seem to like it, but a driver who has used the battery to overtake can be left unable to defend. He said there is potential in the rules, they need tweaking rather than reverting, and they should be given time. He said some Suzuka corners will be less spectacular.	FIA Backbone
SIG-0029	2026-03-26	Oliver Bearman	Driver	Mixed	Driver skill and sporting purity, Spectacle and entertainment, Institutional trust and accountability	it feels just a little bit overkill at this stage Bearman said the racing is good for the show but overtaking feels overkill, because a faster car or a better move does not guarantee holding position. He said the Suzuka qualifying recharge change makes the cars slower and suggested alternatives, and praised the FIA as receptive.	FIA Backbone
SIG-0030	2026-03-26	Liam Lawson	Driver	Mixed	Driver skill and sporting purity, Stability and patience	real racing feeling that we are used to is just slightly different Lawson agreed with Norris and Bearman. He said the rules have potential and will improve, but planning a move can still end with being passed back, and energy management now dominates weekend preparation.	FIA Backbone
SIG-1024	2026-03-26	FIA (institutional)	FIA	Defends	Driver skill and sporting purity, Stability and patience	the first events under the 2026 Regulations have been operationally successful Ahead of the Japanese GP the FIA cut the qualifying recharge limit at Suzuka from 9MJ to 8MJ after driver and team feedback. It said the first events were operationally successful and called the change a normal optimisation, with more discussions scheduled.	Formula1.com (quoting FIA statement) Supplementary
SIG-0031	2026-03-27	Ayao Komatsu	Team leadership	Noncommittal	Feasibility and implementation	being the smallest team, that challenge was, I'd say, even bigger Komatsu said preparing for the new regulations was a huge challenge, larger for the smallest team, and that early-season reliability issues are normal under brand-new regulations.	FIA Backbone
SIG-0032	2026-03-27	Koji Watanabe	Manufacturer	Noncommittal	Feasibility and implementation, Competitive balance	Under current regulation it's difficult to improve the performance itself Watanabe said the new power regulation is quite challenging for Honda and that, under the current regulation, it is difficult to improve performance, so Honda is focused on reliability and improving performance within the rules.	FIA Backbone
SIG-0033	2026-03-28	Andrea Kimi Antonelli	Driver	Defends	Driver skill and sporting purity	qualifying today has been good fun Antonelli said parts of Suzuka limited drivers because of energy, but the Esses and the chassis were good fun and lap times were close to last year. He said work remains to let drivers push more without thinking about energy.	FIA Backbone
SIG-0034	2026-03-28	Oscar Piastri	Driver	Noncommittal	Driver skill and sporting purity	you end up going slower because the engine doesn't like it Piastri said that with these cars a driver can go faster through corners and still end up slower because of the power unit, and that being slower in the Esses was not necessarily bad, which he called weird to say.	FIA Backbone
SIG-0035	2026-03-29	Andrea Kimi Antonelli	Driver	Noncommittal	Safety	the FIA is already looking into how to improve for Miami Asked about Bearman's crash and closing speeds, Antonelli said it is a big issue and very tricky, and that the FIA is already looking at improvements for Miami in qualifying and the race.	FIA Backbone
SIG-0036	2026-03-29	Charles Leclerc	Driver	Mixed	Safety, Driver skill and sporting purity, Stability and patience	I actually enjoy these cars for the racing bit Leclerc said drivers must race differently and that changing direction while super clipping creates dangerous scenarios. He enjoys the cars for racing, but said qualifying needs tweaks, and that race safety will also improve as drivers adjust.	FIA Backbone
SIG-0037	2026-03-29	Oscar Piastri	Driver	Critical	Safety, Feasibility and implementation	it's what we're stuck with, with the power units Piastri said large closing speeds had been foreseen since the cars were conceived and are hard to avoid with these power units. He described a close call in practice and said some things need to be looked into quickly on safety grounds.	FIA Backbone
SIG-1025	2026-04-15	Stefano Domenicali	Formula One Management	Mixed	Business and economic climate, Spectacle and entertainment, Driver skill and sporting purity	We are managing it in the right way, with no panic Domenicali said fan reaction to the racing was very positive, attendance and TV numbers were up, and the rules exist to keep manufacturers. He accepted criticism about qualifying and safety, said the regulations have to be improved, and said criticising for its own sake has zero effect.	Motorsport.com Supplementary
SIG-1026	2026-04-19	Mohammed Ben Sulayem	FIA	Noncommittal	Institutional trust and accountability, Safety	The drivers have provided invaluable input on adjustments Before the 20 April meeting, Ben Sulayem said the FIA had held constructive talks with drivers, who gave input on energy management changes to ensure safe, fair and competitive racing, alongside technical meetings with teams, manufacturers and FOM.	RacingNews365 (quoting social media post) Supplementary
SIG-1027	2026-04-20	FIA (institutional)	FIA	Mixed	Safety, Driver skill and sporting purity, Institutional trust and accountability	Refinements to the 2026 FIA Formula 1 regulations agreed by all stakeholders After an online meeting of the FIA, team principals, power unit manufacturer CEOs and FOM, the FIA announced refinements from Miami: recharge cut from 8MJ to 7MJ, superclip power raised to 350kW, boost capped at +150kW, deployment limits outside acceleration zones, a low-power start detection system and wet-weather changes. It said the changes target excessive harvesting and closing speeds while keeping overtaking.	FIA (fia.com) Supplementary
SIG-1028	2026-04-20	Mohammed Ben Sulayem	FIA	Noncommittal	Institutional trust and accountability, Safety	the drivers have been at the heart of these discussions Ben Sulayem praised the speed and collaboration of the work, thanked drivers for their input, said safety and sporting fairness were the FIA's top priorities, and said the changes address issues from the opening events before an exciting season.	FIA (fia.com) Supplementary
SIG-1029	2026-04-20	Frédéric Vasseur	Manufacturer	Noncommittal	Competitive balance, Spectacle and entertainment	it will go in the direction of someone or against someone Vasseur said fine-tuning is for the benefit of the show, but that every change, even marginal, helps or hurts some manufacturer because each designed different turbo and battery sizes.	The Race Supplementary
SIG-1030	2026-04-20	Mattia Binotto	Manufacturer	Noncommittal	Road relevance and sustainability, Fairness, Business and economic climate	I think that Audi has not been part of the 50/50 decision Binotto said Audi joined for high-efficiency engines, sustainable fuel, significant electrification and removal of the MGU-H, not specifically the 50/50 split, and that turning rule changes political would be wrong because all share an interest in improving the sport.	The Race Supplementary
SIG-1031	2026-04-20	Toto Wolff	Team leadership	Defends	Stability and patience, Institutional trust and accountability, Safety	act with a scalpel and not with a baseball bat Before the 20 April meeting Wolff said talks among drivers, FIA, F1 and teams were constructive, changes should be targeted after only three races, the sport is in a great place, and stakeholders should not criticise the sport in public; he warned against nostalgia.	Motorsport.com Supplementary
SIG-1103	2026-04-23	Andrea Stella	Team leadership	Mixed	Feasibility and implementation, Driver skill and sporting purity	a positive step in the right direction Stella said the changes for Miami are a positive step that address the issues McLaren raised in Bahrain testing, but F1 should stay open to further tuning once their effect is seen. He said a more substantial improvement, such as easing the energy shortage, may need power unit hardware changes like battery capacity or more fuel flow, which take longer than a season to implement.	ESPN Supplementary
SIG-1032	2026-04-25	Nikolas Tombazis	FIA	Defends	Stability and patience, Driver skill and sporting purity	no one believed that the patient, our sport, was in intensive care Tombazis described the Miami package as evolution, not revolution, said the sport was never in crisis, and said the FIA believes it has a good package. He said the changes rest on thousands of simulations and reduce unnatural ways of harvesting energy.	Motorsport.com Supplementary
SIG-1104	2026-04-25	Zak Brown	Team leadership	Defends	Stability and patience, Spectacle and entertainment	I think it was the same noise as the hybrid era Brown said it is only three races into the rules and early reactions tend to be dramatic, and that the changes made for race four should be a good improvement, with further steps to wait and see. He compared the criticism to that at the start of the hybrid era, which he said turned out fine. He said drivers are unhappy but the racing has been very exciting on television, and the corrective action aims to keep that while giving drivers a proper car.	Speedcafe Supplementary
SIG-0200	2026-04-30	Oscar Piastri	Driver	Mixed	Feasibility and implementation, Safety, Driver skill and sporting purity	never going to fix the problems without changing the hardware Piastri said the collaboration on the Miami changes was good and the changes, especially to the boost button, were a sensible step for safety. He said they were very small changes and the problems cannot be fixed without changing power unit hardware; the cars are still very heavy and some issues may need a complete overhaul.	FIA Backbone
SIG-0201	2026-04-30	Sergio Pérez	Driver	Mixed	Safety, Institutional trust and accountability, Spectacle and entertainment	from a safety point of view there was urgency to change things Perez said it was good to see teams, the FIA, Formula 1 and drivers working together, and the changes should improve the show, the feeling of the cars and qualifying. He said the Suzuka incident was very scary and created urgency for safety changes, and more changes could follow before Canada. He agreed the sport is in great shape.	FIA Backbone
SIG-0202	2026-04-30	Nico Hülkenberg	Driver	Mixed	Driver skill and sporting purity, Safety	especially how to prepare the energy for a quali lap Hulkenberg said the changes, made in the spirit of safety and closing speeds, should make qualifying less complicated and allow more pushing. He said the new cars can be exciting to relearn, but energy preparation for a qualifying lap was complex and small things had big consequences, which the adjustments should address.	FIA Backbone
SIG-0203	2026-04-30	Carlos Sainz	Driver	Mixed	Driver skill and sporting purity, Safety, Institutional trust and accountability	in reality F1 should be flat-out racing, so I have countered feelings Sainz said he was happy that the FIA, FOM, drivers and teams reacted together and the changes are sensible, though not a magic bullet. He praised the chassis, aero and following, but said needing to think about state of charge is not pure because F1 should be flat-out racing.

SIG-1046	2026-07-23	Max Verstappen	Driver	Critical	Driver skill and sporting purity, Spectacle and entertainment, Institutional trust and accountability	You're not allowed to make a difference At the Hungarian GP media day Verstappen said more people now see the problems he predicted, that faster cornering is penalised on the next straight, and that overtakes often happen by doing nothing. He said the boost-button remark F1 cut from social media summed up 2026 overtaking.	Autosport Supplementary
SIG-0612	2026-07-24	Simone Resta	Team leadership	Noncommittal	Feasibility and implementation	it's a very complex new set of regulations with the power unit Resta said the power unit regulations are complex and teams are still learning after ten races, attributing George Russell's deployment issue to a software bug Mercedes has fixed. On 2027, he said the aero tweaks were discussed in the Technical Advisory Committee and he does not expect a dramatic change in ride height.	FIA Backbone
SIG-0613	2026-07-24	Adrian Newey	Team leadership	Noncommittal	Feasibility and implementation	they are tweaks rather than completely different regulations Newey said next year's aero changes, including a shorter T-tray, fewer floor fins and rear wing changes, are tweaks that remove some downforce rather than a fundamental change in the flow regime.	FIA Backbone
SIG-0614	2026-07-24	Pierre Waché	Team leadership	Noncommittal	Feasibility and implementation	some limitations in the regulations that could limit what we are doing Waché said that, in terms of efficiency, the regulations impose limitations that could limit Red Bull's development. He agreed that next year's aero changes are a tweak to reduce downforce, with no massive change to the regulations.	FIA Backbone
SIG-0615	2026-07-26	Max Verstappen	Driver	Critical	Driver skill and sporting purity, Competitive balance	most of the time, you don't really enjoy it Verstappen said this year has been a bit of a jungle and that most of the time he does not really enjoy driving, which he linked to running low on battery. Asked about Red Bull's engine situation, he said he would love to have some ADUO as well.	FIA Backbone
SIG-1047	2026-07-29	Stefano Domenicali	Formula One Management	Defends	Business and economic climate, Institutional trust and accountability, Innovation and competitiveness	not here to put the tape on the mouth of anyone In a summer-break media call Domenicali said the championship is at its highest in following and attendance, drivers may have opinions but he has a duty to decide what is best for the sport, and he prefers to discuss issues privately. He said the rule change was needed to keep manufacturers.	Autosport Supplementary
SIG-1048	2026-07-29	Formula One Management (institutional)	Formula One Management	Defends	Spectacle and entertainment, Business and economic climate	F1 says its fanbase has responded largely positively Formula 1 reported that in its Fan Voice panel of 60,000 fans, 66% rated 2026 races good or excellent versus 60% the year before, with only the British GP rated notably lower.	Autosport Supplementary
SIG-1049	2026-08-03	Nikolas Tombazis	FIA	Mixed	Feasibility and implementation, Institutional trust and accountability, Spectacle and entertainment	We did try to make some adjustments, but we failed Tombazis said the FIA anticipated many driver complaints before 2026 and had tried to adjust the rules but could not under the manufacturer governance agreement; he called it a shame the 2027-28 package came only now. He said a near 50-50 split was always challenging but most races have been exciting.	Autosport Supplementary
SIG-0616	2026-08-20	Max Verstappen	Driver	Mixed	Driver skill and sporting purity	the rules are slowly getting a bit better Asked what changed after he had been unsure about his future, Verstappen said the question was mainly about staying in Formula 1, that the rules are slowly getting a bit better and he is willing to live with them, and that he hopes V8 engines around 2030 offer another opportunity. He confirmed four more years at Red Bull.	FIA Backbone
SIG-0617	2026-08-21	James Vowles	Team leadership	Noncommittal	Competitive balance, Feasibility and implementation	this is by far the largest regulation change we've ever done Vowles said the 2026 change is the largest he has seen in 26 years and exposed teams without established systems. He said next year brings a power unit change and an aero regulation change, and asked whether every regulation change will benefit teams with established systems and widen the gap.	FIA Backbone
SIG-0618	2026-08-21	Ayao Komatsu	Team leadership	Noncommittal	Competitive balance	gaps are much bigger than last year Komatsu called 2026 the biggest regulation change ever and said that, as the smallest team, Haas expected to struggle in the development race. He said gaps across the field are much bigger than last year.	FIA Backbone
SIG-0619	2026-08-22	George Russell	Driver	Defends	Driver skill and sporting purity	the energy management these days is a little bit more straightforward Russell said energy management is now more straightforward than drivers were describing at the start of the season and pre-season. He expected teams' deployment strategies to converge for the race.	FIA Backbone
SIG-0620	2026-08-22	Charles Leclerc	Driver	Noncommittal	Competitive balance, Spectacle and entertainment	surely it's a big differentiator on a year like this year Leclerc said deployment strategy is a big differentiator this year with the new cars and that his overtake would not have been possible without a different strategy between teams. He said teams have converged since the first races, when there was more action.	FIA Backbone
SIG-0621	2026-08-23	Lando Norris	Driver	Mixed	Spectacle and entertainment, Competitive balance	it's worse than DRS was last year Norris said that when both cars press boost the following car gains no advantage, which he called worse than DRS last year, leaving less opportunity to overtake. He also said the championship is relatively close for a new regulation set, closer than previous new-regulation years, and that the car is trickier to drive this year.	FIA Backbone
SIG-1101	2026-09-02	Frédéric Vasseur	Manufacturer	Defends	Feasibility and implementation, Competitive balance, Institutional trust and accountability	I think overall the job is well done Vasseur told Autosport that ADUO helps but in-season engine development is very difficult and costly, so the scope to develop during the season is marginal. He said criticism of how ADUO works has a point but all parties agreed to it, and he sees the value of bringing manufacturers close together. He said he is still upset about the change to the start procedure, but that the rules are a huge challenge for the FIA and overall the job is well done.	Autosport Supplementary
SIG-0800	2026-09-03	Lewis Hamilton	Driver	Critical	Driver skill and sporting purity, Spectacle and entertainment	still doesn't feel ultimately the best, but it is what we have Hamilton said cars will arrive at Monza's braking zones 20 to 30 km/h slower than before and drivers will downshift before braking, which he said still does not feel the best to him, though everyone faces the same issue.	FIA Backbone
SIG-0801	2026-09-03	Oliver Bearman	Driver	Critical	Driver skill and sporting purity, Stability and patience	a little bit less enjoyable to drive Bearman said that on energy-limited tracks such as Spa, Monza and Baku the regulations make driving more sensitive and less enjoyable, citing corners lost at Spa and lower gears at Monza. He called it a shame but said he expects it to improve over time.	FIA Backbone
SIG-0802	2026-09-03	Andrea Kimi Antonelli	Driver	Defends	Driver skill and sporting purity, Spectacle and entertainment	it's going to be much better than what we all anticipated Antonelli said Monza in the simulator was not as bad as he expected because the harvest limit had been changed for the track to reduce super clipping. He also said the energy-starved circuit creates many overtaking opportunities.	FIA Backbone
SIG-0803	2026-09-03	Liam Lawson	Driver	Noncommittal	Driver skill and sporting purity	maybe more punishing if you get it wrong Lawson said Monza under these rules would be very different and more punishing if a driver spends too much energy, but probably a little better than expected.	FIA Backbone
SIG-0804	2026-09-06	Max Verstappen	Driver	Noncommittal	Driver skill and sporting purity, Competitive balance	it's just too powerful for us to actually really defend that Verstappen said Red Bull could not match the deployment of Mercedes-powered cars at Monza and that rivals using overtake mode were too powerful to defend against even on better tyres. He said racing was enjoyable but frustrating when cars drove past him.	FIA Backbone
SIG-0805	2026-09-10	Fernando Alonso	Driver	Critical	Driver skill and sporting purity, Spectacle and entertainment	are not the best cars to drive and to enjoy Alonso said, as he has said many times, that the current cars are not the best to drive or enjoy, and called this year a 'battery championship' with unwanted overtakes on cars with empty batteries. He said the 2027 changes are a step in the right direction but the cars will still reward charging in high-speed corners and at the end of straights, and he hopes the 2027 rules are tweaked again before he decides his future.	FIA Backbone
SIG-0806	2026-09-11	Mike Krack	Team leadership	Noncommittal	Procedural only	I think the sport needs someone like that Asked whether the 2027 changes Alonso wants could persuade him to stay, Krack said it is not one thing Alonso wants changed, that the sport needs someone like him, and that what can be done to accommodate that will be done.	FIA Backbone
SIG-0807	2026-09-11	Marcin Budkowski	Team leadership	Noncommittal	Competitive balance	this year it's a bit more stretched with the new regulations Budkowski said the cost cap has brought teams close in performance, though this year the field is a bit more spread out with the new regulations.	FIA Backbone
SIG-0808	2026-09-12	Lando Norris	Driver	Critical	Driver skill and sporting purity	better if we just had no battery and more power Norris said the banked Turn 12 is not the biggest challenge because drivers must save the battery through the first part of the corner, and that it would be better with no battery and more power; he said in a few years it may be more fun.	FIA Backbone
SIG-0809	2026-09-12	Max Verstappen	Driver	Critical	Driver skill and sporting purity	I wanted to go flat, but then my battery dies Verstappen said he wanted to take the banked Turn 12 flat but had to lift so the battery would deploy better, and that the battery runs low towards the end of the corner.	FIA Backbone
SIG-1050	2026-09-21	FIA (institutional)	FIA	Procedural only	Procedural only	reduction in the total race distance from 305km to 290km The third F1 Commission meeting approved cutting 2027 race distance from 305km to 290km in line with the 2027 fuel-flow changes, plus changes to disrupted-race timing and gearbox homologation.	FIA (fia.com) Supplementary
SIG-0810	2026-09-23	Charles Leclerc	Driver	Noncommittal	Competitive balance	a lot of variability from one weekend to the other Leclerc said that with this year's car there is a lot of variability in performance from one weekend to the next, based on how teams optimise the power unit.	FIA Backbone
SIG-0811	2026-09-23	George Russell	Driver	Noncommittal	Driver skill and sporting purity, Feasibility and implementation	his natural driving style suits very well for this regulation Russell said the 2026 car and tyres are very different, that driving styles which worked for him and Piastri do not work as well now, and that Antonelli's natural style suits this regulation. He said the rear tyres were developed with the previous power units, which had less power off the corners, and that next year's chassis and power units will be largely unchanged.	FIA Backbone
SIG-0812	2026-09-24	Mattia Binotto	Manufacturer	Mixed	Competitive balance, Stability and patience	The ADUO concept is still valid. The fine-tuning is required. Binotto said the ADUO catch-up system was meant as a safety net and to support convergence, that it is not ideal yet and needs fine-tuning, and that a top team may benefit from it. On further 2027 tweaks, he said significant changes are already coming for 2027 and he would be patient and see their effect first, while staying open to discussion.	FIA Backbone
SIG-0813	2026-09-24	Laurent Mekies	Manufacturer	Critical	Competitive balance, Driver skill and sporting purity	the regulations were not exactly perfect Mekies said the ADUO regulations were not exactly perfect and Red Bull would welcome discussion on changing them. He said the 2027–28 roadmap is a clear step forward from where things are now, and Red Bull would support further tweaks towards flat-out qualifying and flat-out racing, as Alonso and Verstappen suggested.	FIA Backbone
SIG-0814	2026-09-26	George Russell	Driver	Noncommittal	Driver skill and sporting purity	We've had a lot of conversations this year about PU energy management Russell said the final stint at Baku was the most fun he had had in a race for a long time because there was no tyre management. He said there has been much discussion of power unit energy management this year, but tyre management has existed for years.	FIA Backbone
