Components 1 races are gained on the monitor, however the groundwork to making a successful machine kicks off months earlier than lights exit on a grand prix weekend. Within the buildup to each new season, designers and engineers pore over the principles searching for loopholes – ones they’ll exploit within the title of pace.
The advances generally go a step past discovering a niche within the laws, and develop into a break within the guidelines. When that occurs, whether or not the innovation is successful races or proving to be a security hazard, it may be outlawed by F1’s governing physique, the FIA.

This may imply that complete automobiles are outlawed from coming into F1 races or, on different events, groups need to re-engineer their machines to conform.
However simply what sort of technical wizardry has Components 1 outlawed in its 75-year historical past? Nicely, these are 10 of probably the most high-profile improvements which have been banned from F1.
Brabham BT46B – ‘The Fan Automobile’
From the entrance, Brabham’s BT46B appears to be like virtually like another Nineteen Seventies Components 1 automobile: it’s bought a low profile, huge stance and a rudimentary wing at every finish. One facet of the automobile that was removed from rudimentary, nonetheless, was the big fan that was engineered into the automobile to extend downforce.
Commercial
‘The Fan Automobile’, because it was affectionately identified, made its F1 debut on the 1978 Swedish Grand Prix in Anderstorp. To assist efficiency, Brabham engineers related a fan on to the automobile’s gearbox utilizing a fancy array of clutches. This diverted round 30hp from the engine to the fan, which then sucked air out from beneath the ground of the automobile.
The concept proved profitable, and the additional downforce that was created by the spinning fan helped Niki Lauda to a race win in Sweden. Nonetheless, Brabham determined to withdraw it from competitors for the rest of the season. The automobile wasn’t really banned from F1 following its first race, however a regulation change in 1979 meant that it could have been outlawed from the next 12 months.

The considering was that having 4 wheels on the entrance as a substitute of two would enhance the contact patch with the monitor, aiding traction within the corners and serving to with braking efficiency. Certain, pitstops would take longer with an additional pair of tyres to alter, however that might be offset by the on-track features.
The speculation labored, and Patrick Depailler certified third on the P34’s first outing on the 1976 Spanish Grand Prix at Jarama. He went on to endure a braking challenge that meant he didn’t end the race, however two weeks later the P34 helped Jody Scheckter to fourth in Belgium. The automobile even managed a single race win and bought its drivers onto the rostrum on 14 events.
The novel design was short-lived, nonetheless, as growth of the mini tyres important for the entrance wheels was minimize by Goodyear and the particular rubber grew to become scarce by the top of the 1977 season. What’s extra, a technical directive within the Nineteen Eighties meant that Components 1 automobiles might solely use 4 wheels – no extra, no much less.
Lively suspension
Within the early Nineteen Nineties, groups had moved on from analogue upgrades to give attention to extra high-tech enhancements, like energetic suspension, which introduced powered parts to F1 automobiles to watch and alter the suspension whereas drivers traversed a monitor with a view to maximise grip and efficiency.

Lotus was, as soon as once more, an early pioneer on this house and the primary victory for a automobile with energetic suspension was in 1987 when Ayrton Senna gained the Monaco Grand Prix for Lotus. The tech reached its heyday within the Nineteen Nineties, nonetheless, when automobiles had been capable of robotically alter the experience top in any respect 4 corners with a view to keep a flat and steady place.
The large benefit of the tech was that it offered a extra steady aero platform, which gave engineers a greater understanding of how they might maximise the efficiency from their automobiles. This, coupled with different improvements of the time, meant that speeds shortly rose and lap occasions plummeted.
Nonetheless, the added complexities and prices related to energetic suspension led to its demise and it was outlawed in Components 1 from the 1994 season.

Nowadays tuned mass dampers are utilized in super-tall skyscrapers, to assist address robust winds, and top-tier mountain bikes, the place they clean out bumps on a gnarly downhill monitor. However, within the mid-2000s, these sprung plenty had been initially used to nice impact in Components 1.
A tuned mass damper is a weight that’s held in place inside a tube and has a spring at both finish. This straightforward creation strikes towards an interference to offset it, so in tall buildings it helps cease the sway in a powerful breeze and in F1 it helps enhance stability.
The standard system was utilized by Renault in its 2005 R25 Components 1 automobile, with the workforce initially putting in a sprung 10kg mass within the automobile earlier than realising that the quantity of weight required might be tuned for every monitor it visited. The extra weight proved efficient, because it was stated to offer drivers and extra confidence. It was additionally stated to be value as a lot as a second a lap by way of efficiency on some tracks.
The system confronted a protest following the 2006 German GP, and Renault opted to run its automobiles with out the system from then on to keep away from disqualification. In a later listening to on the courtroom of attraction, the mass damper was outlawed by the FIA, which deemed that it was a tool that aimed to “markedly enhance the automobile’s aerodynamic output.”
Double diffuser
With any overhaul in laws in Components 1, there’s at all times an opportunity that one workforce will discover a loophole that lets them maximise efficiency. When new guidelines got here into power in 2009 to try to minimize the quantity of downforce produced by F1 automobiles, the double diffuser exercised one such loophole.
Commercial
The double diffuser was a tool deployed by groups together with Brawn GP, Toyota and Honda – however the former managed to maximise the effectiveness of the aerodynamic system. It created channels within the rear diffuser to maximise its floor space with out exceeding the scale said within the laws.

Are you aware what’s higher than one DRS? Two. At the least, that’s what thought with the novel entrance wing design it deployed in 2011 after which refined in 2012.
For 2011, a creation dubbed the W-duct sought to have an identical impression on the entrance wing because the F-duct had on the rear. Specifically, it redirected the airflow to stall the entrance wing and minimize downforce to assist prime pace.
Commercial
This technique was refined in 2012 and comprised pipework that ran via the automobile from the entrance wing to the rear to stall each wings and minimize drag produced by the automobile. Groups subsequently sought to outlaw the creation, as implementing it themselves meant discovering house of their automobiles to weave pipework from entrance to rear.
What’s extra, the system turned out to be a hinderance to the Mercedes workforce in its personal entrance wing growth. That is as a result of the innovation took place when groups up and down the grid had been pushing the pliability of their wings to the acute, and Mercedes wasn’t capable of capitalise on this as a result of building of its personal wings.
Regardless of some groups additionally working to implement double DRS programs of their very own, the innovation was outlawed for the 2013 season.
DAS system
After successful six constructors’ crowns on the bounce, Mercedes was in a league of its personal come 2020 and was all about refining its dominant equipment. So, for 2020, the German producer rolled out a singular steering system that sought to additional enhance the hole to the competitors.

The innovation was noticed in pre-season testing when drivers and Valtteri Bottes had been seen pulling on their steering wheels, in addition to twisting it left and proper to show the wheels. Pulling the wheel, it turned out, altered the alignment of the entrance wheels, which might change the contact patch between the tyre and the highway.
Makes use of for the system ranged from aiding tyre warmup following a security automobile interval to enhancing mechanical grip to enhance cornering efficiency. Mercedes was permitted to run the system for the 2020 season, however the FIA moved to outlaw the setup from 2021, which put different groups off deploying programs of their very own.
Flexi wings – 2024
The most recent controversy to rock Components 1 has been versatile wings. Wings on the entrance and rear of Components 1 equipment have been seen flexing beneath load, which implies their profile reduces at pace and a discount in drag.
Commercial
Versatile wings have been a problem in F1 for years however . A technical directive rolled out in 2024 sought to scale back the permitted flex in wings and applied more durable assessments on wing flexibility.
An extra technical directive as a consequence of hit the grid on the Spanish Grand Prix will additional clamp down on versatile wings in F1. From the Spanish race, groups will solely be permitted to have entrance wings that may flex by 10mm when beneath load. Moreover, the flex on the slot gaps on rear wings should be no larger than 0.5mm as soon as the technical directive comes into power.
