Components 1 races are gained on the observe, 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 foundations in the hunt for loopholes – ones they will exploit within the title of pace.
The advances generally go a step past discovering a spot within the laws, and grow to be 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 will imply that whole vehicles are outlawed from getting into F1 races or, on different events, groups must re-engineer their machines to conform.
However simply what sort of technical wizardry has Components 1 outlawed in its 75-year historical past? Effectively, 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 seems virtually like some other Nineteen Seventies Components 1 automobile: it’s bought a low profile, extensive stance and a rudimentary wing at every finish. One facet of the automobile that was removed from rudimentary, nonetheless, was the large fan that was engineered into the automobile to extend downforce.
‘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 linked a fan on to the automobile’s gearbox utilizing a posh 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 thought proved profitable, and the additional downforce that was created by the spinning fan helped Niki Lauda to a race win in Sweden. Nevertheless, Brabham determined to withdraw it from competitors for the rest of the season. The automobile wasn’t truly banned from F1 following its first race, however a regulation change in 1979 meant that it could have been outlawed from the next yr.

Floor impact
Brabham’s fan automobile was created to rival the bottom impact Lotus vehicles of the Nineteen Seventies, which used skirts on both aspect of the automobile to seal the hole to the bottom and maximise the downforce created by the underside of the automobile. It was a philosophy that helped Crew Lotus to its seventh F1 constructors’ title in 1978 with the enduring Lotus 78.
As soon as Lotus proved floor impact might win races, different producers quickly discovered methods so as to add it to their vehicles. Racers started creating an increasing number of downforce as the idea was fine-tuned, and that meant vehicles might lap race tracks faster and faster.
The aspect skirts on the racers introduced with them a danger that the seal could possibly be damaged and the downforce might immediately be misplaced, nonetheless. Due to this added security concern, floor impact vehicles had been banned from F1 for the 1983 season. They made a comeback within the collection with the launch of the brand new laws in 2022, however the brand new interpretation of floor impact vehicles did away with aspect skirts with the hope of lowering the prospect of a sudden lack of downforce.
Six-wheeled vehicles
Automobiles have 4 wheels and bikes have two, so what do you name one thing with six wheels? A Tyrrell P34, apparently.
The 1982 Tyrrell P34 was a funny-looking creation, because it changed the 2 entrance wheels that just about each different F1 automobile in historical past has had with 4 wheels break up between two entrance axels.

The considering was that having 4 wheels on the entrance as an alternative of two would enhance the contact patch with the observe, aiding traction within the corners and serving to with braking efficiency. Positive, pitstops would take longer with an additional pair of tyres to vary, however that could possibly be offset by the on-track beneficial properties.
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 undergo a braking subject 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 turned scarce by the top of the 1977 season. What’s extra, a technical directive within the Eighties meant that Components 1 vehicles 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 lively suspension, which introduced powered elements to F1 vehicles to watch and alter the suspension whereas drivers traversed a observe with the intention 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 lively 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 vehicles had been in a position to mechanically regulate the experience top in any respect 4 corners with the intention to keep a flat and secure place.
The massive benefit of the tech was that it supplied a extra secure aero platform, which gave engineers a greater understanding of how they might maximise the efficiency from their vehicles. This, coupled with different improvements of the time, meant that speeds rapidly rose and lap occasions plummeted.
Nevertheless, the added complexities and prices related to lively suspension led to its demise and it was outlawed in Components 1 from the 1994 season.
Mass dampers

Nowadays tuned mass dampers are utilized in super-tall skyscrapers, to assist address sturdy winds, and top-tier mountain bikes, the place they easy out bumps on a gnarly downhill observe. 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 in opposition to an interference to offset it, so in tall buildings it helps cease the sway in a robust breeze and in F1 it helps enhance stability.
The standard machine was utilized by Renault in its 2005 R25 Components 1 automobile, with the staff initially putting in a sprung 10kg mass within the automobile earlier than realising that the quantity of weight required could possibly be tuned for every observe it visited. The extra weight proved efficient, because it was mentioned to present drivers Fernando Alonso and Giancarlo Fisichella extra confidence. It was additionally mentioned to be price 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 vehicles with out the machine from then on to keep away from disqualification. In a later listening to on the court docket of enchantment, 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 staff will discover a loophole that lets them maximise efficiency. When new guidelines got here into power in 2009 to attempt to minimize the quantity of downforce produced by F1 vehicles, the double diffuser exercised one such loophole.
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 machine. It created channels within the rear diffuser to maximise its floor space with out exceeding the scale said within the laws.
Watch: Why The Double Diffuser Was (Down)Pressured Out Of F1
Brawn used the machine to nice success, successful six of the primary eight races within the 2009 season, and that yr’s titles. The success of the machine opened it as much as scrutiny, and rival groups protested the legality of it for 2009. The protest failed, and rivals needed to rapidly fast-track double diffuser designs of their very own.
By the top of 2009, virtually each staff on the grid ran a double diffuser, and the design largely carried over into 2010. Nevertheless, new laws introduced in from 2011 successfully closed off the loophole that had allowed them to be put in within the first place.
F-duct
One other innovation that took place in 2010 was the F-duct, which was first applied by McLaren on its MP4-25.
The machine was one other easy thought, because it comprised a vent within the nostril of the automobile that drew air in and both directed it out by an inactive exhaust, or fed it over the rear wing to cut back drag and enhance straightline pace. The path the air was fed initially relied on the place of the motive force’s knee, as they might cowl or uncover a vent to vary the circulation of air within the automobile.
Different groups scrambled to implements F-ducts of their very own, with differing ranges of success… and security. In a single occasion, the duct was operated by a driver taking their hand off the wheel, which led the FIA to step in.
The machine was banned for the 2011 season and was, in the end, changed by the Drag Discount System.
Double DRS

Have you learnt what’s higher than one DRS? Two. Not less than, that’s what Mercedes 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 analogous influence 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 help prime pace.
This technique was refined in 2012 and comprised pipework that ran by 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 vehicles to weave pipework from entrance to rear.
What’s extra, the machine turned out to be a hinderance to the Mercedes staff 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 in a position to capitalise on this as a result of building of its personal wings.
Regardless of some groups additionally working to implement double DRS methods 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 novel steering system that sought to additional enhance the hole to the competitors.

The innovation was noticed in pre-season testing when drivers Lewis Hamilton 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 street.
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 methods of their very own.
Flexi wings – 2024
The newest 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.
Versatile wings have been a difficulty in F1 for years however the FIA is making an attempt to clamp down on them greater than ever proper now. A technical directive rolled out in 2024 sought to cut back the permitted flex in wings and applied more durable exams on wing flexibility.
An extra technical directive because 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 have to be no higher than 0.5mm as soon as the technical directive comes into power.
