Formula 1 will see a major shake-up in 2026 as it moves to new power units and all new engine regulations. The overhaul will see combustion engine power drop, while the electric motor power will be increase significantly, nearly three times! This will dramatically change the way the vehicles perform, and how teams will develop winning strategies.
We'll discuss the big picture items, like how fuel flow rate will be changing from mass flow to energy flow, how the fuel chemistry will be changing, sustainable fuels, the MGU-K & MGU-H (or lack thereof), the energy allotments per lap, and what this all means for straight line speed. We'll also look at the newly introduced airflow limits, and discuss the implications this may have on air/fuel ratios.

I really think active aero is coming because the level of aerodynamic drag we have now with reduced full power as a function of the increased power still with 4MJ swing... I'm very unexcited about '26. Great explanation!

@Mike23443 Год назад

No, there won't be active aero in f1. The sport has always had the mission of developing new technology to introduce into regular cars later down the line. Aero isn't practical for regular cars because they're too slow to generate it. Active suspension is the next thing they'll allow. Especially with them moving towards ground effect aero, active suspension would benefit these cars a lot more than active aero, and developing new suspension technology can and will be useful for regular cars, especially given how heavy they'll be getting with all those batteries.

@Ninja98x Год назад

Maybe it would make a comeback eventually but in the short term I think we'd see the teams focus on reducing drag as much as possible. I could see there being a tradeoff point where it's faster to have more straight line speed, coast longer (thus recharging the batteries more), than higher cornering speed. Which is really backwards to think about because normally faster corner speed = quicker lap times, but we're talking about an edge case here. Kinda like the hybrid LMP1 cars, where at Le Mans they were slower at the end of the straights than the non-hybrid LMP1 and they had less downforce. But they made up for it by being able to deploy the electric boost early on the straights. Much like a drag race where if you launch hard enough off the line, you can get to the finish line first even if your opponent has a higher trap speed.

@Ninja98x Год назад

@@Mike23443 that's not exactly true. Hell even pickup trucks have had (for a decade now) active grille shutters to reduce drag at highway speeds.

@user-qx4bp5rf3n Год назад

@@Mike23443 That depends how you define aero. I'm pretty sure he is referring to optimizing drag rather than downforce - which in that case ties into fuel efficiency rather than aero grip.

@brrrake Год назад

@@Mike23443 disagree completely. We're talking about the sport that has DRS which has no relevance for road cars. The main issue with the 26 regulations is a reduction in possible output and reducing drag via movable surfaces is far superior to active ride height control. They WILL need a way to reduce drag.

@LupinYonderboy Год назад

What annoys me is the hybrid era is in the name of reduced emissions. If they really wanted to reduce F1 emissions, they'd have fewer races in the season! By far the biggest polution in F1 comes from shipping the whole circus from country to country. We could have kept the V10s and knocked a few races off the calendar and had a greener, more exciting sport overall.

@C.I... Год назад

Even changing the order of races would improve things massively in that regard. It won't even matter when the switch to synthetic fuel, so I don't understand why they wouldn't just make them sound good by allowing 3 litre NA V12s at that point.

@EMPower91 Год назад

That is a good point. If that were the case though, the engineers wouldnt be pushed to limits of extracting as much as possible from the available technology.

I think the min air temp and max pressure is to try and close some loopholes someone discovered. Maybe using the turbo pressure as a simple air pump that can be used to run the engine briefly on no fuel. The air temp may be for preventing teams from using cryogenic air to super cool the inter coolers in the pits before going on track, especially for qualifying. Some rules are to prevent edge cases and loopholes that F1 engineers are famous for finding

@davelowets 10 месяцев назад

No. Cooling the intercooler with a cryo gas prior to qualifying would do basically nothing as an advantage. It takes laps for the car to get up to speed and start the timer, and ANY cooling effect "sprayed" onto the intercooler in the pits would be LONG gone by then

@JainZar1 2 месяца назад

The Intake cooler is an air/water intercooler. Switching on the pumps for the hot lap, could reduce the temperature for the inlet air to below that 10 K limit. And depending on what interval the 3 GJ/h is measured, you could get more power out of the engine than intended. The pressure limit is basically there to reduce development and engine costs. Else you could make the motor far smaller for the same power, which would be a huge weight saving.

13:46 : the engines may very well be running around λ~3. The pre-chamber allows them to do so with a closer-to-stoichiometry mixture inside it and a much leaner mixture in the main cylinder, way beyond the flammability limits for gasoline/E20, as you already indicated, which can however ignite this time due to the jets bursting out of that pre-chamber. The beauty of TJI it is! 😊

Yes, discussed in my previous video. Studies indicated λ~2 possible with active pre-chambers (something F1 isn't using, only passive). So it's not nearly as simple with limited control. More here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KjrNcuc89Pc.html

My point was that limits, currently possible in latest F1 engines, are way beyond λ~2, as the whiteboard alluded to! Controlling combustion is of course the key here. Mixture preparation is really crucial, which is important to capture very accurately using CFD simulations. Stratification levels inside the pre-chamber are extremely high, due to the shape of body and orifices, which ultimately dictates the λ levels close to the electrodes.

Former F1 design engineer here... great video. Done tons of these calcs over the years... all looked good to me. Years ago (probably 2016) we had a working group to think of ideas around the energy flow diagram, to a) see if we could figure out what Ferrari was doing cleverly and b) try to come up with various nefarious ways to do similar or worse. Mercedes was quite risk-averse, but we really had nothing left to unturn at that moment... we looked at hybridization of ancillaries, various battery layouts etc... but most of the efficiencies found in these rule sets are in combustion/lean-limit optimizations (through fuel formulations, atomization strategies, air injection, mixing etc...) and MGUH strategies. Since the latter is gone, you will see a lot of time spent on fuel... Could you make a fuel which has a lhv at one temp and another as it raises? Or one that has the same attributes at different pressures? Those things will be tried. I am confident you will see another step change in BTE, which will bring these back to 50%.

@@MC-re9zj Speculated yes, possibly that they were altering the fuel flow rates out of phase with the fuel flow meter. Meaning that the fuel flow meter checks the rate in pulses rather than continuously, so if you can raise the rate in between check pulses you can get an advantage. Also rumors that they were deliberately allowing thin engine oil to either leak past the cylinder into the chamber, or into the intake via a deliberate leak in the turbo charger. Thereby using engine oil as a fuel booster. The evidence was the limits placed on engine oil burning shortly after. There's also been rumors of pre-chamber fuel tanks in the engine, with the idea being that fuel flow can be increased at times when the engine is reving low to fill a tank on the engine side of the fuel flow meter. That way you can increase fuel flow into the engine when needed but still comply with the sensor. This one was the crackpot theories of how the Mercedes Party Mode supposedly worked, but it was later revealed that the engine was just functionally 2 years ahead of development of everyone else so they had power to spare early in the Turbo hybrid era and were turning the engines down to save mileage.

@@gkinghsmith9352not sure about the tight balancing act. seems like the more rules you introduce the less balancing you have to do, and the more the rules dictate your choices. for instance if there is no power limit you might not want to have the most power because more power is less drivable, less reliable, wears tires quicker and uses more fuel ( more weight) now if you have a pretty "low" fuel flow limit like current and incoming rules, power is limited and you want to have all of this limited power other wise you'll get passed on the straights... same for fuel, if you have a high minimum amount of oxygen that reduces fuel energy density, you might want to use the least amount allowed to get the best energy density. makes it easier for everyone to optimize the parameters, you reduce the research costs and make teams more equal regardless of the budgets. seems like it's where they're heading probably trying to make F1 more exciting to watch...the tight balancing act is there, trying to create healthy competition without going too far and transforming F1 into racing series where all cars are identical

I think those IAT and charge air pressure limitations are aimed at preventing F1 teams from adapting some sort of crazy charge air regulator system on the engine intakes. They could theoretically run insanely highly charge air pressures (15+ bar) air through the intercooler and then run that high pressure/near ambient temperature charge air through a high flow rate regulator to reduce the pressure to a more reasonable useful manifold pressure while drastically cooling the charge air in the process due to adiabatic expansion. This could get IATs far below ambient at the regulation intake pressure (possibly even to freezing temperatures depending on the expansion ratio), greatly increasing intake air density, and also improving combustion stability. I tried to design something like this for a regular turbo car, but it wasn't feasible for a regular car/engine setup. It was far too complex, cumbersome, expensive, difficult to manufacture by hand, and would have required a crazy tuning solution because of the additional sensory/feedback inputs to compensate for variable ambient temperatures and available boost/turbo lag. The returns were also diminishing on a regular vehicle setup and theoretical benefits were mostly only in the super high rev range (IE even more turbo lag). F1 teams wouldn't have the same limitations, and they are chasing milliseconds so they could pull it off, and possibly consider it as a valuable proposition.

Although the max battery usage calculations are correct AFAIK (I'm not gonna check your math, mine is usually bad), it only takes into account one straight, not the whole lap. Since the current regs only allow 4MJ of energy deployment per lap instead of the theoretical 6 (4 in the Energy store, 2 recovered at some pointt) and the new regs removed that limitation completly, you might be limited in the very long straights like you mentioned in Baku, but you have far more available energy deployment per lap (max 13MJ, 4 ES + 9 recovered).

another great video! much appreciated. one question: you make a comment that implies that fuel with a higher octane rating delivers more power. my understanding is that increasing octane slows down combustion allowing higher combustion pressure/temperature and reducing detonation or pre ignition - so an engine with high compression ratio (or higher turbo boost) would require a higher octane to perform as designed. My 1973 Porsche was designed to run on the then-available-in-the-US "unleaded" - it has an 8.5 to one compression ratio and runs well on the lowest octane fuel I can buy today. It will not put out more power if I run a higher octane fuel, in fact in runs worse. A modern car with computer control and knock sensor will put out more power with a higher octane fuel as it can optimize fuel and spark maps, correct?. I'm thinking that this is what you meant.

Keeping everything constant is most important for those big diesels. About F1 I wish they'd give the teams more freedom in the engine design and development. even the choosing of the number of cylinders, from a I4 to a v12, what ever you like. only limit: fuel, supplied by the organiser, in a known quantity. here you have 50L, and the lights are off and goo.

Would you consider this a possibility?

@Ninja98x Год назад

I don't think so, because at lower RPM the fuel flow limit is also lower. For example at 8000 RPM you can't use as much fuel as you can at 10,500+ RPM, so if you already have quite a lot more air than you need at 10.5k, there's no benefit to having that much air at 8000 RPM with less fuel.

to counter this octane limit, you could flip the entire table and make a compression ignition engine (a diesel) that uses completely bio diesel (made from plant oils), diesel has a verry low octane but weirdly it needs high compression to ignite, thus making it more efficient, there are diesels out there running compression ratio's of 30isch to 1 WITH a turbo producing way more boost than a gasoline engine, in a gasoline engine you'll never see more than 5 bars boost, while a factory diesel can run up to nearly 7,5 bars (heavy industry) and a purpuse made race car could probable have even more, the engine is a bit heavier though and the revs are limited, but with some F1 engineering there's probably a way around the weight of the engine so it can rev higher

@edbowejr6130 2 месяца назад

It’s for lower rpm, at lower rpm they can push more fuel and air per stroke of the engine into the engine and then as RPMs climb they will how to actually bleed off the air pressure as they begin to be limited by fuel volume. In a way, this will help with turbo lag but also a lot of low end torque with the batteries and no traction control could make for very interesting passing attempts and spinning out of corners

@engineer_cat Год назад

I don't think the intention is to limit the air mass flow rate. I'd guess that they are separately limiting (a) boost pressure, to stop teams cranking the boost WAY up - possibly for safety/reliability reasons? - and (b) intercooler performance - probably to try to head off an arms race of bigger/more complex cooling systems for marginal gains in charge air density. Now yes, those two together do impose a de facto limit on mass flow rate at the intake, but as you say that limit would give very lean combustion, and no-one's likely to hit it.

I wonder what the difference would be like in a case like this, where about 3-times the e-motor power gets delivered in 1/3rd of the time; how would that pan out in the time it takes to cover a certain distance on a track. The math could be worth a shot. I had done a deep dive into the new regs myself previously but didn't run the numbers, and boy am I shocked now! I am of the opinion that with the extremely painful elimination of the MGU-H, the engines will now sound better, even more so if the supposed exhaust system tweaks are brought into place.

The more power from electrick motors can actually make acceleration much better and so the lap times can actually go better. But lets see!

Williams did that a number of years ago. It was insane, and undriveable. Literally the driver wouldn't be able to cope with the forces on his/her body. Given further advancements now, I've no idea what it would be. But removing the rules is pointless, the racing is about comparable cars. Hence the name "Formula 1". this is racing of cars in that category.

If it were possible to run strippers (CAT's) in the intake / charge cooler to increase O2 density then it could make sense to limit air intake volume which could also explain how F1 can apparently run so lean

Is there any way to use an electric motor connected to a vertical pole with a pickup strip at the top. The track could be metal with a negative charge & the vertical pole could pick up from an overhead mesh with a positive connection. I seem to remember this setup at out local town fair. Thoughts?

Love the bumper car idea. Many F1 fans may be too young to get it. Ah, the smell of ozone in the air. And besides, the drivers already play bumper cars at all of the starts.

@avsystem3142 Год назад

Electric induction coils in the operating surface to supply electrical power to vehicles would be more suitable, both for bumper cars and F1.

I miss the days of unlimited power where they were making 1500+ HP BUT! I understand why they’ve made changes over the decades, some of them are pointless, some take away excitement, but other rules increase the competition on the engine building side, the sport has to evolve. They should still have a secondary sport called F-Zero that is unlimited like the days of old.

Could the airflow limit stop teams from making power much lower in the rev range? For example, if the engine is only spinning at 5000rpm at times then the airflow limit will stop them from going leaner than 1.4 or even 1.2 with the higher air temps you mentioned and that does seem like a limit teams might bump into.

@evoluke1069 Год назад

They're already limited to less energy flow rate of fuel at lower rpms as per the purple graph in the video so I don't think that's it either, good idea tho

It's pretty easy to get below ambient temperature with a turbo and intercooler. If you cool the pressurized air to near ambient and then expand it - it will be below ambient. I've seen it many times on turbo/intercooled cars when the intercooler (or piping) acts as an inherent flow restrictor for which there is a pressure drop across. That's probably why they have a temperature limit, otherwise they could still continue to increase flow by increasing boost and expanding it through a restrictor to the maximum allowed intake manifold pressure but driving the temperature down instead of the pressure up. There is a company using scuba tanks for forced induction drag racing, and the inlet temp ends up being like -150F, and they can use near stoich air/fuel mixtures with "normal" ignition advance as if it were naturally aspirated - but making several times the output.
