Possible solutions to improve the 2026 Engine Regulations

Post

Think this forum needs a space to talk a bit about this. I will list two...
  • 8MJ Battery - will increase weight but will ensure enough battery for more than a lap and so wont have to worry about super clipping in quali, in the race the driver will only have to lift off a bit latter into the race. They will need a plug in system to charge the cars in the pits though as without that the cars will need 2 laps just to charge the battery to full capacity. Not to mention the car will go past 900 kg makit it difficult to drive
  • Higher engine power with no elettric boost - Engine can run at 700 hp and when the electric motor kicks in it drops to 500hp and when it electric motor shuts of about 320kph, 500hp to run and 200hp to charge the battery in a power split hybrid system, again will increase the weight but will also heavily increase spendings as many engine redsign would be required or simplay allow an extra turbo, it will solve the start issue as well so basically the cars can run on ICE alone for the first lap
Halo not as bad as we thought

1. reintroduce MGUH as a spec part
2. allow higher fuel flow and reduce electrical harvesting (thus reducing the ICE/battery split to about 65/35)

I’m curious as the difference changing the maximum deployment down to 250kW (& maintaining 350kW of regen) would make?
Cars won’t be hugely affected by the reduction - they are already traction limited - would it affect the deployment time enough to at least get the clipping down to the level seen in the previous regulations?

Would the 130bhp peak reduction translate to better average power (area under the curve) & faster lap times?
I’d be really interested to see a proper simulation.

1. Offer a spec MGUH at a fixed price, but let the teams have the possibility to make their own also. The trick is to balance the rules so it's worth it making your own, but not be doomed with the spec part.

2. Greater flexibility with engine layout. Wanna use a 1.2 R4 Turbo at optimum RPM? Go for it. Efficiency is king.

Problem is that for most car manufacturers it's *not* worth making their own hence the reason why Audi didn't want to join unless they got rid of it. If you have a spec MGUH but also let teams make their own, the teams with the existing infra for that research will have an advantage.

Normally I roll my eyes at the spec series / BOP-style complaints for F1, but in this instance because of how expensive MGUH is compared to how unused it is in most regular road cars, it makes sense to me.

For the power unit...

I think at least qualifying needs to be saved.. Not from an entertainment point of view (because i am satisfied really) but from a driving point of view a driver must be flat out in Q and right now they are lifting to charge batteries!!

I realise adding power to the ICE is too risky. I take that back. Instead, cut the MGUK power to half!! But only for Qualifying.

Yes lap times will be slower but who cares... At least it allows drives to go flat out. The straights will be hilariously slow but at least the driver is pedal to the metal! Lol

The most overlooked and flawed aspects of '26

Post

In the midst of the noise, talk, stormy opinions, no one asks THE fundamental question:

WHY DESIGN SOMETHING THAT IN THE END PERFORMS WAY UNDER ITS OWN CAPABILITIES? If sustainability is the current magic word (usually without proper context and content), then WHAT A WASTE TO PRODUCE ANYTHING that is NOT properly tuned to its capabilities/limitations? Are these cars overengineered? Or engineered to a nonexistent environment that was based on pink memories?

A current F1 car does and can not operate at peak performance - ever. The ICE and the electrics can not add their maximum performance at all times. Because of the limited cornering speeds the entire concept of grip is just lukewarm milquetoast swimming in a bowl of flavorlessness. The cars can NEVER reach the aerodynamic optimum, and max downforce is simply not needed because they are turning way slower than possible - thanks to that utter BS energy management. So, based on the ACTUAL cornering speeds, the ultra-sophisticated aero is unneeded. Why build it that way? These speeds can be maintained by smaller (more efficient, more sustainable - remember?) tires, because again, the cars are NOT operating at the limit of adhesion we'd find on their theoretical white papers. The V6 turbo is choked with maxed out fuel flow as they can never reach their allowed peak RPMs, so why specify it? Can you imagine a 100m run where Usain Bolt has special shoes which will grain at 30m, lose grip at 80m, and shorts that start to slide down his legs every 25 meters to provide more exciting racing?

A cheetah's, a greyhound's, a marlin's look is not coincidental. They are purpose-built exactly for speed, because it's the main factor that guarantees their survival. If a sport is based on speed, the fanbase will fade away if the cars start to grow grocery baskets on them. No one wants to see naturally aspirated diesel marlins, or cheetahs with Flintstone-drive. Such conceptual abominations are destined for the Taygetos of tech. The cars look like precision instruments, like predators, but they are - just to quote some lustless world champions - "chef's utilities/antiracers/battery champions". In nature, you should learn that red-yellow-black-yellow is a venomous predator, but the red-black-yellow-black is a harmless lookalike. I think we deserve the originals, so why should we go with the Fauxrmula 1?

When there was talk about that the cars "would hit 400km/h", the only thing that hit was cruel reality when the MGU starts to scale down and disappear in the fog. The ICE is now too gutless to rule over the air and the spectator can NOT cheer for the highest terminal velocity cars. Fans watching the TV, will see the blatant LIE when F1 takes away the onboard, to keep the illusion alive that the cars are actually fast at the end of the straights and the drivers need serious balls to take the corners.

We have wonderful initial accerelation for a couple of seconds. Can these seconds compensate for the lost soul, the essence? Who knows? With a stricter deployment/harvesting ratio the cars could master the corners in the future with pure mechanical grip. If we can harvest the most at 30km/h, so be it, and let solid fuel rockets compensate for it which can push the cars exactly for 2.3765 seconds. As their thrust start to vanish, the broadcast will switch to the crowds to find somebody awake, to wave for the camera.

So we need suspensions/tires/brakes/aero for a way lower average cornering speed. Top speeds are roughly the same. Wow, great achievement. In theory, they have only one mission: to provide an unforgettable (SENSORY RACING!) experience by balancing on the edge and rewarding the utmost in driver's skills. This entire generation of cars are just an empty promise or an example of overpromising/underdelivering. Overtakes are not overtakes, just the kind of power surges two ambulance teams can experience when they are competing with defibrillators.
- ZAP! Oh, mine is alive! Oh, fck, not...
- It's mine! ZAP! Told ya!
- Nooot, my friend! ZAP! See???
We are cheering that maybe they can bring them back, but the motions are just the results of the jolts and not signs of life. Instead of zaps, I'd be content with infernal sounds, spectacular glowing discs, the smell of racing fuel (not green, floral grass compost tea), loud bangs, some decent fire spitting (blue flame during acceleration, orange flames on downshifting) and heck, it is also spectacular when an overstressed engine is incapable to contain its combustions on the internal side. When a recipe is unnecessarily more complex than flour, water, salt and sourdough, you should avoid it. If you can not pronounce the ingredients, you should avoid it. If a fan/spectator/viewer doesn't have the slightest clue about what's happening, it's not the way to do F1.

And talking about skills: have you listened to the full radios? It is painful to hear world champion drivers asking (somewhat helplessly) when and where they should act totally counterintuitively as they forcibly shut down their instincts, and they have to rely on their engineers who are directing them where to find some more holy juice, or where to go even slower to conserve the (of course, proper racing) tires - because y'know, going slow = going fast. Fans don't get it.

If these rules would be the norm everywhere, people would build balloons with a hole - and a compressor with solar panels on them to pump back the escaping air and call it an intellectual tour de force. I think there is only one thing that is even more useful: a peeled airless balloon with no string on it. Oh, I heard that the rulemakers had taken an IQ test, but luckily, it came back negative...

So even a hundred words have only one ending: just let these cars accelerate as hard as they can; under 50km/h, or above. Let them turn as fast as they can; so that 0.2km/h more and they are falling off the track. Let them brake as hard as the tires allow it. Let the engines sing at their max RPMs (true 15.000, anyone?) on the straights. Let the drivers be just happy. Build tires that can joyously sustain these speeds for a long time. Ad absurdum, give the purse of the champion team to the weakest at the year's end. We need more true overtakes, right? Then maybe a little more equality would mean more overtaking on the teams' level. No year long reigns, no top teams for decades. Excitement. Let everything to be in its element. Let the cars use their full capabilities they are built for. And don't hide the CAFE of the entire F1 organization behind a nonexistent green mask. The cars and their fuels are just homeopathic parts of this. Don't LIE. We don't need demigods to order the pundits to say nice things and cover up the truth. Is shadowspeech a new word? Don't let the slightest bit of politics to creep in. Simplify to truth and true sustainability. When you reach it, unspoken burdens vanish and the magic appears.

Similar thread here:

viewtopic.php?t=32511
I'd argue this thread is less rant focused and more about speculative solutions to it.

Changes possible after discussions post-Japan:

1. Changed deployment curves

As for me. I'm no longer entirely sold on dropping the MGU-K output below 350 kW in the short term. However I do believe that the power dropoff can be more aggressive, placing more focus on traction zones and less focus on deploying for outright top speed. I see no reason why deployment couldn't start dropping at 270 kph and hit zero at 325 kph, rather than 290 and 345, respectively. I'd love to see less energy wasted on fighting drag and more of it focused on the strengths of these cars, which is rocketing out of corners. It would place more focus on getting on the throttle early, and would go well with my next idea.

2. Reduced harvesting caps:

The best and most immediately available band-aid solution to drivers not pushing all-out, especially in quali, is to reduce the harvesting caps. There is regulatory scope to do so for individual races, and there is no reason why harvesting targets couldn't be dropped by 1-1.5 MJ from what was originally planned in order to get less harvesting. Obviously it would come at the cost of lap time, but with a lot of deployment currently happening at relatively high speed down the straights, the places where pace would be lost would likely mostly be on the straights. That is okay, since top speed isn't interesting to the viewer. The average viewer doesn't care about if the driver hits 360 kph or 330 kph.

Longer term changes: 2027-2028

1. Find a way of getting the MGU-H back or introducing front axle regen. (likely 2028 at the earliest) The MGU-H is obviously the cooler piece of tech, and would likely help to redistribute deployment strategies a bit due to the increased ICE torque you get at low speed with no turbo lag. A conservative estimate would place MGU-H harvesting capacity at ~3 MJ around an average lap, assuming 3000 MJ/hr. That would make it a lot easier to hit the harvesting cap, at least on quali laps.

2. Otherwise, getting ICE power up by increasing fuel flow to 3600 MJ/hr, or preferably even 4000 MJ/hr would bring a lot of power back to the ICE, and would make the speed dropoff caused by super clipping less pronounced, or even prevent it entirely on slower straights, since the cars could push through the drag on their residual power. If they do increase fuel flow a lot. You could even tune the super clipping rate for individual tracks or straights, such that super clipping would not slow down a car with the expected drag characteristics and speed down the fastest straight on the track. Obviously they would still stop accelerating, but they wouldn't be slowing down.

If you do increase fuel flow to 400 MJ/h, the cars would have about 380 bhp left while super clipping at 250 kW. I'm not sure what top speed that could sustain with the drag characteristics of these cars, but since they can seemingly sustain 360+ kph off only the current ~530 bhp, it is likely that we would still be in the mid-300s. Napkin math suggests they can maintain at least ~330 kph while super clipping with fuel flow set to 4000 MJ/hr, assuming they can sustain 360 kph purely from ICE power with current fuel flow. In reality it might be closer to 350 kph while super clipping, since road friction doesn't increase with the square of speed, and since we don't actually know if they top out at 360 kph or if they can go faster. Still, at 4000 MJ/hr, super clipping would not be an issue, at least visually.

Regulatory changes:

As for regulatory changes, they should immediately drop ADUO and the weird homologation rules that prevent certain upgrades. It makes no sense to have a system aimed at preventing spending wars when the PU development is already under a budget cap. All it does is create perverse incentives to sandbag and play politics to prevent teams from catching up quickly, just like the token system in the early turbo hybrid era. Engine development is always a game with diminishing returns, so teams that lag behind will always have an easier time finding more performance than the dominant team, meaning ADUO is just a negative.

Realistically Audi could perhaps try to purchase the Renault MGU-H IP to get a solid start. You could also straight up limit MGU-H harvesting to a level which would be easily achievable, instead of having the 2014 style battery bypass (which resulted in unlimited harvesting).

If you reintroduce the MGU-H I'd say it should be spec only; not road-relevant, so not much to gain there for any OEM.
In my humble opinion any regen should never prevent the max performance for at least cornering, and topspeed should top out flat instead of falling back by 20/25%. No one cares if top speed is let's say 330 or 360 kph, the superclipping or LiCo on straights looks really silly and takes away the wow-factor. Overtakemode is fine I guess as a sub to DRS, and even the punishment is ok though might be a little less. And a driver should somehow earn those MJ's a bit more, so maybe only available once a lap or every other lap. In the end, maintaining DRS with cars that couldn't follow closely for too long paid the tire deg price.

Anyway, not based on numbers .. I'd say a 70:30 ratio (or even maybe 65:35), so slightly bigger ICE output if possible (>fuelflow), maybe a little smaller battery, and more agressive flattening of the electrical deployment at top speeds.
Anything to avoid any superclipping, and/or rewarding granny speeds in cornering.

I would like F1 to be more driver-limited than batt-tech/pu limited.

Porsche might disagree. The newest 911 is using eTurbo, aka. mguh. Will we see more of the same from others soon?

It’s only relevant in track cars. Other cars don’t generate enough excess exhaust pressure, meaning there is no energy to be harvested.

So yes, the 911 and other sports cars have some use for it, but it is limited, and certainly not road relevant.
