F1 automobiles are the quickest automobiles on this planet. Their unbelievable energy and pace imply that all the things wears out a lot sooner, the tires, the engine, the brakes… in order that was making me assume: Do F1 automobiles refuel?
F1 automobiles haven’t refueled since 2010 when the FIA determined to ban them to scale back the fee and improve security. At the moment, the automobiles begin the race with a full tank, and the drivers should handle the gasoline nicely in order that they don’t run out earlier than crossing the end line.
It’s true that with refueling, there have been extra different and thrilling methods, however many instances pointless accidents occurred that put the lives of drivers and mechanics in danger.

Why Don’t F1 Vehicles Refuel Anymore?
From the Austrian GP in 1982, when the Brabham workforce tried to begin with a half-full tank till 2010, F1 automobiles refueled throughout races.
This added one other dimension to racing, as other than the same old tire technique, there was additionally the gasoline technique. Groups struggled to search out probably the most environment friendly technique, making an attempt to guess how a lot gasoline their rivals had put into their automobiles, particularly when qualifying included setting your quickest lap with race gasoline.
Some races had been fairly thrilling with the addition of refueling, though many others weren’t that thrilling both. The FIA determined to ban refueling from the 2010 season primarily for 2 causes:
The primary one price. The price of transporting, caring for, and storing gasoline could be very costly, so refueling required groups to have extra gasoline and due to this fact raised the worth. It’s estimated that the price of refueling was round a million euros per 12 months for every workforce.
The opposite motive was security. With refueling, there have been many accidents, corresponding to leaks, drivers pulling out of the pit too early with the gasoline line nonetheless hooked up, or issues when inserting it, inflicting gasoline to spill in all places and ending a lot of them with fires.
Within the following video, we are able to see some of the spectacular and grotesque accidents associated to pit refueling. In the course of the 1994 German GP, Jos Verstappen was making his pit cease, and instantly gasoline from the filler hose spilled out into the automotive and brought on an enormous fireplace, which was put out instantaneously. Because of the fireproof race fits worn by the drivers and mechanics, nobody was injured.
How Lengthy Did It Take To Refuel In F1?
Since refueling was banned in 2010, pit stops have turn out to be a lot sooner, as mechanics solely have to alter the tires if there isn’t a injury to the entrance wing. Present pit stops seem to be an ideal choreography between the mechanics and the automotive and final between 2 and three seconds.
With refueling, having to insert the gasoline hose, watch for it to empty, and take away it, pit stops had been a lot slower and extra arduous. Relying on how a lot gasoline was wanted, pit stops may final between 7 and 12 seconds.
Within the following video Sebastien Buemi, who drove for Toro Rosso between 2009 and 2011, explains one in every of his pit stops through the 2009 British GP. He additionally explains how filling the gasoline tank impacts the driving when leaving the pits:
Will Refueling Ever Return To F1?
As a lot as many followers and a few drivers need it, it’s unlikely that, at the very least, within the short-medium time period, it would occur. Aside from price discount and security, F1 shouldn’t be eager about bringing again refueling.
F1 now not desires to present the picture of excesses, waste, and air pollution of previous many years. As an alternative, F1 is changing into more and more sustainable and environment friendly, which implies the less sources used, the higher. F1 plans to turn out to be carbon impartial by 2030 by means of ultra-efficient logistics, cut back all its emissions and use reusable supplies.
This may be verified, for instance, by trying on the evolution of the engines. The sound of the V10 and V8 was spectacular, however they had been removed from the goals of F1. The present V6 turbo hybrid engines are the quickest in historical past and likewise probably the most environment friendly.
In 2016 the attainable return of refueling to racing to “enhance the present” was debated however was lastly rejected, because it had extra cons than execs and went in opposition to the picture that F1 was searching for sooner or later. Some drivers favored refueling since they might go sooner because the automotive would weigh much less, however for the spectators, this distinction wouldn’t be noticeable.
All that mentioned, if F1 desires to present a picture of higher effectivity and sustainability, it could be counterproductive for automobiles to refuel mid-race.
How A lot Gas Does An F1 Automotive Use?
F1 automobiles can use a most of 110 kg of gasoline per race (305 km / 109 miles). Nevertheless, groups don’t often fill all the tank to make the automotive lighter and due to this fact sooner per lap and fewer put on on the tires.
The present V6 turbo hybrid engines eat round 34 liters of gasoline per 100 km, making them very environment friendly contemplating the speeds they attain.
With the arrival of those new engines in 2014, a most of 100 kg of gasoline per race was set, a 3rd lower than earlier V8 engines, but it surely was elevated in 2018 to 105 kg and 2019 to 110 because of the new introductions that made the automobiles heavier, such because the halo or the higher width of the tires and automobiles.
As we have now already talked about, at the moment’s engines are probably the most environment friendly in historical past. For instance, the 2020 Mercedes engine has a thermal effectivity of greater than 50%, which implies that greater than half of the gasoline’s power is used to energy the automotive, representing a rise of round 44% in 2014. As a standard street automotive reaches solely about 30% thermal effectivity, this demonstrates the effectivity positive aspects in F1.
How Do F1 Vehicles Not Run Out Of Gas?
In F1, all the things is studied intimately. There’s a group of engineers accountable for gasoline administration in every workforce. In winter testing and through the season, they preserve observe of sure calculations on the amount of gasoline utilized by the automotive in every lap, analyze the automotive’s efficiency, and modify their calculations in accordance with the automotive’s modifications.
Additionally they have in mind the kind of format and environmental situations that will have an effect on gasoline consumption. Throughout free observe classes on Fridays, groups do lengthy and quick runs at race and qualifying tempo to see gasoline consumption and different variables corresponding to tire put on.
That’s the reason, earlier than a race, the engineers have sufficient info to know the way a lot gasoline to place within the automotive, with out extra however with out lacking. As soon as within the race, the motive force should handle the gasoline consumption by means of the directions of their engineers.
Vehicles not often run out of gasoline. It appears counterproductive, but it surely was extra frequent for them to expire of gasoline when refueling, as groups had been risking extra.
How Is The Gas Of An F1 Automotive?
The gasoline utilized in F1 automobiles is extra like regular automobiles than you may assume. They’re 99% alike since F1 gasoline incorporates virtually the identical elements as regular gasoline and the distinction is simply in some components and their proportion.
Earlier than gasoline composition was regulated in F1, virtually any sort of gasoline and additive was used. F1 groups’ suppliers used mixtures with a whole lot of corrosive energy, so the engines needed to be disassembled after use for cleansing. These fuels additionally had dangerous results on well being resulting from their poisonous vapors. As of 1989, the FIA (then FISA) determined to control the composition of the gasoline utilized in F1 to be as shut to standard as attainable.
Additive mixtures have a tendency to alter a little bit from one circuit to a different, relying on the traits of the format, and it’s all the time sought that it weighs as little as attainable. As well as, every workforce has a unique provider, which offers particular gasoline for its engine. With different fuels, its efficiency wouldn’t be the identical.
Can F1 Vehicles Use Regular Gas?
An F1 automotive wouldn’t begin on regular gasoline because of the detonating energy of 1 and the opposite. The octane variety of regular gasoline is way decrease than that of F1. A excessive octane quantity creates a phenomenon generally known as self-detonation, which causes the fuel-air combination to spontaneously ignite earlier than the flame explodes.
Nevertheless, within the hypothetical case that it may begin, the automobiles would barely go a number of tenths per lap slower as the 2 fuels are so comparable. This is able to be a notable distinction in qualifying and within the race, the place the instances between automobiles are very tight, however they’d not be so gradual when it comes to pace.
How Will F1’s Sustainable Gas Be Made?
By 2022, F1 will change the gasoline composition to be extra sustainable and can turn out to be 90% fossil gasoline and 10% ethanol, in comparison with the present gasoline that’s 5.75% ethanol. F1 guidelines will mandate that the ten p.c ethanol have to be “second-generation biofuel” that has been produced sustainably, that means it would have a near-zero carbon footprint.
Nevertheless, that is solely a small step for the longer term. To fulfill its net-zero carbon footprint dedication by 2030, F1 will use a completely sustainable gasoline from 2026, when its new engine rules take impact.
This new gasoline might be laboratory-created, produced from a course of that harnesses carbon seize, municipal waste, or non-food biomass. It’s estimated that it’ll produce 65% fewer greenhouse gases than regular fossil fuels.
This is able to have nice advantages not just for sustainability and effectivity but additionally for F1 itself since it’s anticipated that modifications like this one can appeal to extra producers because the world’s huge automotive manufacturers are additionally concerned in sustainability tasks.
It’s reported that the Volkswagen Group has been concerned in negotiations to enter F1 from 2026 when these modifications happen, with one in every of its main manufacturers Audi or Porsche (and even each).
Occasions change, and F1 modifications with it. Earlier than, the “cool” was extra, luxurious, and waste, whereas now the essential factor is sustainability and the setting. Refueling was banned for exactly that motive, though many opposed this transformation. That’s the reason gasoline consumption can be reducing, and engines are more and more environment friendly.
We should do not forget that neither previous instances had been so good and instances to come back usually are not so dangerous. All the things modifications, not essentially for the higher or for the more serious; it simply modifications. We followers are desperate to see the place F1 evolves with these sustainable modifications and the way useful they are going to be for competitors and racing, which is a very powerful factor.
