FIA admit changes required to make 2026 cars faster – When Formula 1’s new regulation set for the 2026 cars and power units was first unveiled ahead of the Canadian Grand Prix in 2024, the reception from paddock observers was lukewarm warm. The FIA vision of the next F1 era had promised a radical rebalancing of the formula—lighter, nimbler cars with active aerodynamics, paired with power units split evenly between internal combustion and electrical energy. But lurking behind the glossy renders and FIA bullish press releases was a problem that threatened to embarrass the sport: the new cars were projected to be significantly slower.
For a championship that sells itself as the pinnacle of motorsport, being two or three seconds off the pace of today’s machinery was never going to fly. Drivers, engineers, and even the fans grumbled that Formula 1 risked producing cars slower than Formula 2 in some conditions. That criticism has now pushed the FIA and the teams to act, and the result is a set of tweaks that have clawed back much of the lost performance.
Nikolas Tombazis, the FIA’s head of single-seater matters, has been the man most publicly defending the new formula. Speaking recently, he confirmed that the incoming cars will now be roughly “one second slower per lap” than the current generation—rather than the three-second deficit feared last year.
F1 cars wold have been three or more seconds slower
“There has been an increase of performance of the car by probably about 50 points of downforce,” Tombazis explained. “This has brought the performance from what maybe was minus 40% compared to current cars, to around minus 15% in terms of downforce. In terms of performance, the resulting lap time of the cars is very close to current cars.”
Without the changes, the cars may have bee visibly slower to the fans attending the Grand Prix, but the FIA changes are not a wholesale rewrite but a series of aerodynamic adjustments designed to recover lost grip. The front wing number of elements allowed has been increased, thicker endplates are back, and fences—banned since 2019—return to help redirect airflow.
As far as the floor is concerned, new “leading edge devices” are now allowed, with up to five sections, giving teams a crucial area of freedom to enhance the underfloor downforce performance. This together with a larger and relocated diffuser will generate further load and therefore grip and the bodywork around the wheels has been rejigged to better control turbulent airflow.
Ground effect reduced
The floors will no longer be full blown ground effect creations, although this method of generating some of the downforce will remain in a minor form and the teams will be able to strengthen the flexibility of the floors, with the stays used currently increased from two or three as is currently the case, to up to six.
Individually, none of these changes sound dramatic. Collectively, they restore aerodynamic balance and downforce, ensuring the cars will not feel like undercooked prototypes.
Formula 1 has long lived by a simple truth: it must look and feel like the fastest racing in the world. Fans tolerate politics, budgets and even gimmicks like sprint races—but they will not accept F1 cars that look sluggish next to junior categories. It is not just about lap time, but about the spectacle: cornering speeds, braking distances, and the visceral impression of speed on television.

But lost is the promise of nimble f1 cars
In that light, the tweaks were inevitable. The FIA could not risk another 2014 scenario, when the turbo hybrids arrived slower and quieter than their predecessors, prompting years of fan complaints. Nor could they repeat the error of 2022, when porpoising turned the sport into a science experiment. For 2026 to succeed, the cars have to be credible on day one.
Yet while the FIA promises the new rules will produce cars only a second off today’s pace, the truth is more complicated. Once teams begin interpreting the regulations, performance gains—or losses—will multiply. Some may find clever solutions that leapfrog the field, others may struggle. The first year of any major rules reset is as much about who got it wrong as about who got it right.
And then there is the elephant in the garage: the power units. With manufacturers splitting power 50/50 between combustion and electrics, while running fully sustainable fuels, the challenge is enormous. Reports earlier this year suggested that only Mercedes is currently confident in its 2026 engine, with rivals floundering. If true, the performance gap between teams may dwarf any aerodynamic tweaks the FIA has made.
History repeats to be avoided
History provides useful reminders. In 2009, new aero rules led to the infamous double diffuser loophole, propelling Brawn GP from bankruptcy to championships. In 2014, Mercedes’ foresight in hybrid technology gave them an eight-year dynasty. In 2022, Red Bull’s interpretation of the new ground-effect rules outpaced everyone, despite McLaren now heading the field.
The pattern is clear: when Formula 1 resets its regulations, winners and losers are decided less by good intentions and more by who best exploits the grey areas. The FIA’s tweaks may ensure the cars are quick enough, but they cannot guarantee the competitiveness will be close—or that fans will see more overtaking, as promised.
A number of drivers have now driver simulated versions of the team’s 2026 proposed cars, with few having anything good to say about them. Such is the concern the huge regulation change will be a disaster, that last week F1’s CEO pleaded for patience.

FIA explain ‘catch up’ mechanism
Addressing the drivers and teams’ concerns, Stefano Domneicali said: “We don’t have to forget that there are two approaches on new regulations. One is tactical, and the teams are playing that game…and this leads to certain comments and views being made. They have some purpose to that [which] is not really the one that we believe, and is the one that is taking them to make some comments.”
Come Australia should the worries expressed come to pass, Domenicali asks for patience and not to be judged, by the initial spectacle on track. “So I would say, let’s wait and see where we are. And then if there is the need to make some adjustment, we don’t have to do it straight away. There is the time to wait a little bit to make sure that we understand exactly what we’re talking about.”
The FIA’s single seater director also said last week, the FIA wold be monitoring closely the performance of each team’s internal combustion engine over the first five races of the year. “For those below a certain level, there will be an upgrade option depending on how far behind. This can mean more money for development, more dyno hours, or more time for specification homologation.”
Newey predicted a power unit dominated formula
Any internal combustion engine more than 3% lower in power than the leading contender will be eligible for the FIA’s upgradable status. The reason the focus is upon the ICE, rather than other aspects of the power unit was explained earlier this season by F1 car design wizard, Adrian Newey.
“There has to be a chance that one manufacturer will come out well on top and it’ll become a power unit-dominated regulation, at least to start with,” said the head of all things technical al at the Aston Martin team. “And there’s a chance, if it’s on the combustion engine side of it that somebody comes up with a dominant combustion engine, that that will last through the length of the formula”, he added.
Newey claimed this in mid-January stating the way the regulations were currently framed “it’s quite difficult for people who are behind to catch up. If it’s on the electrical side, then there’s much more ability to catch up if you’re behind.”
So the FIA has responded to fears expressed from the paddock, but Domenical’s “don’t judge us by race one in 2026” line of thought, hardly provides confidence for fans or drivers alike that the regulations won’t need further re-examination.
Aston Martin F1 owner faces toughest decision yet
Aston Martin has transformed itself from a plucky midfield outfit into one of Formula 1’s most ambitious projects. Backed by Lawrence Stroll’s billions, the Silverstone squad now boasts a state-of-the-art factory, the lure of Honda power units for 2026, and the genius of Adrian Newey guiding its future design philosophy. Yet, amid all the investment and optimism, a persistent question shadows the team: can Aston Martin ever be taken seriously with Lance Stroll in one of its cars?
Since making his debut in 2017, Lance has enjoyed a Formula 1 career few young drivers could dream of. Securing a seat at Williams thanks to his father’s backing, he moved into the family business when Lawrence bought Force India, rebranding it first as Racing Point and then as Aston Martin. In that time, Lance has delivered moments of promise—podiums in Baku, Monza and Sakhir, plus an unexpected pole in Turkey 2020—but his F1 career has been defined more by inconsistency than brilliance.
Statistics can be cruel in their honesty. Over eight seasons, Lance has been routinely outscored and outperformed by teammates. Sergio Pérez beat him comfortably during their time together, Sebastian Vettel—well past his peak—did the same, and Fernando Alonso, still razor-sharp at 43, continues to make Lance look ordinary….
