Next big change for F1 is coming in 2026 with a new car and new engine regs. Audi/Porsche incoming definitely maybe, and talk that Honda might rear its head again.

What are your hopes for the car/engine rules? It’s only 4 years away which isn’t a long period for us to have the current cars… interesting to see what new ideas are brought to the table and if it’ll result in so many different solutions like we had with the 2022 rules despite everyone thinking they were quite prescriptive.

I believe Ross Brawn/Brown is aiming for smaller and lighter cars. Not sure he’s sticking round for much longer, but really hope we finally get a reduction in size and weight in F1

Think he goes at the end of the season, so it will be down to the next person.

F1 usually waits until the last minute to finalise the regulations. I usually think this is a bad thing, but in the case of the 2026 regs, this might actually be a bit of a saving grace when it comes to the engine regs.

 

2024 to 2030 is going to be absolutely transformative for the car industry. In a few years we're likely to be going from a world where ICE engines dominate the market to a world where they're an increasingly niche purchase. Under current plans, it won't even be legal to sell new ICE cars in the UK by 2030. More importantly, if sales numbers keep going the way they are, electric vehicles might make up the majority of the market in countries like the UK, Germany, France and even China by the time these 2026 regs are kicking in.

 

Obviously I'm not saying that F1 necessarily needs to go fully electric in 2026 or ever (horse racing is still pretty popular even though not many of us commute to work on a horse any more), but I think that 2026 becomes F1's "s**t or get off the pot" moment. Do they want the new engine regs to be road relevant, or do they want F1 to be about cool racing cars which are nothing to do with what anyone buying a new car will be driving?

 

At the moment it looks like they want to go for a bit of a fudge (the electric elements of the engine will be a little bit more powerful). This might be the best move, but if I was making half-billion Pound decisions for a manufacturer involved in motorsport, I'd want an extra couple of years to see which way the market's going and to see how younger people's attitudes towards non-electric vehicles are evolving before I decided to commit that kind of cash to a specific set of regulations!

Nightmare scenario. Almost all electric and hybrid cars are garbage.

In your mind would that be F1 using hydrogen in combustion or in a fuel cell?

V10s with sustainable fuel (biofuel?) and KERS please. 
 

A move away from DRS if possible.

 

Active suspension?

New car? We've only just gone back to ground effects.

I wouldn't expect massive changes in the shape of the cars, a new engine formula yes but not so much the aero and all that.

You do know that Ross Brawn will bow out at the end of this year? Perhaps a good idea for you to apply for his position?

Just a few thoughts off the top of my head...
 
I don't want road relevance to interfere with F1 Driver competition.
I want to retain Ross Brawn.
I don't want any batteries - hence no need for regen equipment (weight).
I want a cheap, small(ish) turbo powerplant (say 1200bhp - biofuel) (weight)
I don't want any electronic aids (weight)
I want the Drivers to be in control of the car.
I don't want aerodynamics - (small ineffective non DRS spec wings for stabilisation is fine)
I want the length to be about 4.3-4.5 metres (weight)
I don't want manufacturers involved - start with halving the cost cap.
I want engineers to work on superior suspension systems for mechanical grip.
 
I'm sure I'll think of a few other things down the track...

So, a chassis overhaul in 2026 is also on the table.
The Race reports on this:
https://the-race.com...s-rule-changes/

6 chassis related alterations, that the FOM wants to see happening, will be defined over the coming months:

1) Significantly reduced drag to improve sustainability and efficiency and complement the power unit characteristics.

2) Maintain and improve on recent lessons learned about close racing and cars being able to follow each other.

3) Reduce car dimensions.

4) Reduce or contain car mass.

5) Sustainability. Continue path towards the standardisation or simplification of strategically-selected components for cost-cutting purposes. Expand the usage of sustainable materials or technologies and focus on recyclability.

6) Continued innovation in terms of car safety, moving towards active and connected safety systems.


Numbers 3 and 4 make me very happy! Hopefully it will all solidify over the coming months.

I'm not against this as I'm pro-returning to refueling but not many people will be keen on it, sadly. Having cars that can start themselves is a nice idea though. 

 

+1 for SHORTER CARS, although again, once you include a crash structure and a V engine then you're not leaving much room for a full tank of fuel as we know it today.

Bolded lines describe IndyCar pretty well, though the series is adding electric power in a few years.

They will probably drop 50-60kg and call it a massive success, bringing them back in line with the really light and nimble 2021 cars :stoned:

 Drag = slipstream.  No drag = no slipstream. Quite simple really. A weird target to have.

Why does it even matter? Does it impact your ability to enjoy the racing, how much drag they have? 

 

If we have ultra slippery teardrop cars, there will be no slipstream and passing will die off unless aided by DRS or a driver makes a mistake.

It's hilarious that they say they'll cut the number of tires available to evaluate the effect of that cut on teams running the car during practice. What effect do they think might be in the cards other than a reduction of running, even if only slight?

Yep. Since 2010 iirc the minimum weight has increased 33%, from 600 to 798 kg. Unreal.

 

These cars are absolute pigs, and it really shows in slow corners, in the rain, and with the sudden snaps of oversteer that the drivers frequently have no chance of catching.

Ultimately, maximising efficiency has always been a central part of motor racing in order to gain a competitive advantage.

I think it’s the logical progression for a sport which does rest a pillar of its appeal on tackling advanced engineering challenges. One of the biggest of those out there right now is in how to reduce emissions and mitigate rising energy costs. The name of the game is therefore to do more with less, and it just so happens that this goal is naturally reflected very well in motorsport.

I would personally enjoy seeing F1 embracing that philosophy wholesale. It is, of course, perfectly fine to disagree.

If we have ultra slippery teardrop cars, there will be no slipstream and passing will die off unless aided by DRS or a driver makes a mistake.

Let’s suppose the natural slipstream effect between instantaneously evenly paced cars was practically eliminated… you’re absolutely sure those would be the only two possible remaining ways by which overtaking could occur in future incarnations of Formula One?

It wouldn’t eliminate overtaking. It would just make it even more infrequent which is certainly not what anyone wants to see. Slipstreaming is one of the last non-artificial elements that enables overtaking. Why would we want to get rid of it?

As for the rest, Motorsport isn’t just about efficiency. It’s an optimization problem. There’s a certain amount of downforce/drag you can carry for which the corner speed outweighs the fuel you have to carry with the engine.

Anyway, I think that very little will change in the way of drag. We’ve already shed a ton of it by moving ground effects. Things like front and rear wings will always be in F1 and tire manufacturers are not interested in small wheels which would reduce drag.

The only thing I see remaining that will have a big impact on drag is wheel covers. A counter rotating chunk of rubber exposed to the airflow is a massive drag inducer. However, wheel covers are very un-open wheel. With that said, Indycar style wheel fairings fit the bill.

V-10,  No batteries or energy recovery.  Continue with ground effects downforce.  Similar electronics and standardized engine management systems.  Set a max wheelbase and lower the minimum weight by 200 kg.  Cover the whole green thing with "biofuel".  I want to see, hear and FEEL the cars.  Never happen but how cool would it be?

Bring back refueling and switch to a single dry/intermediate/wet tyre and I will take up arms for this vision of F1.

I just hope in making the cars shorter that they keep the same proportions. The 2000s cars were hideous with how long the fronts were compared to the engine cover sections. Revolting.

And you're still sure about that? With all the possible factors at play - known and unknown - within the future technical and sporting regulations of a lower drag philosophy F1 ruleset, overtaking would definitely be less frequent than today? 

 

Slipstreaming is one of the last non-artificial elements that enables overtaking. Why would we want to get rid of it?

If you think I'm looking at natural slipstream overtakes and thinking 'Hey that sucks, let's end that' you are very much mistaken :lol:

 

It is very much about how F1's philosophy evolves with the world it exists in, one in which efficient and smart use of finite resources it paramount. I fully believe a compelling racing product exists within that space and if F1 does track this way I would be pleased. I do respect, though, that another equally valid philosophy is that F1 should exist solely for itself and simply not worry about any outside factors from the sport. 

 

At the end of the day the one that wins out will be the one that offers the best business case for Formula One's stakeholders.

Ben, a slipstream is a direct result of drag, of the turbulence coming off the car. A low drag formula would result in more difficult overtaking as that’s removing one of the natural advantages for a following car.

Whether that’s a good trade off is another matter.

Your point about slipstreams has been noted.

As for the rest, I think that you can’t have a cake and also eat it, as they say.

The act of racing in general does absolutely nothing for the environment except waste gasoline and other natural resources for our entertainment. I would expect your viewpoint to be that we just close up shop all together or switch to virtual racing series (I.e computer games).

The entire circus is wasteful and I find green racing to be oxymoronic.

A 3.5 litre -era car was only about 4.3-4.5 metres long and managed to fit more fuel and a V10 or V12 though, so I think it would be possible.  It just might hurt the aerodynamicists feelings to have big enough side pods.

A lower-drag car, assuming it was also producing less downforce might be able to deliver roughly the same level of overtaking, as the reduced slipstream effect would be traded off against worse braking performance.  But ideally you'd want to test that out to figure the actual relationship between the two.

 

Or you could go lower-drag by enclosing the wheels, and then you could have a Gen2 Formula E style BTCC-amateur hour feel to F1 as everyone kvetchs about Max Verstappen not knowing how to pass other cars*.

 

*I'm joking people, don't waste a thread on that.

Not that I'm particularly disagreeing with you but it could be argued that the sub-3 seconds stops are even more dangerous (or just as dangerous) as refuelling. There were minimal incidents through the refuelling years, but naturally they looked spectacular and worse than they actually were.

Suggestion for 2026 car regulations:
Cars that can drive in the rain....

In Monaco 2022 we have cars worth a billion sitting on the track, cars that become useless when the road gets wet....

In the rain, I could apparently win an F1 race in a VW Golf, as all those fancy race cars become useless.... 😁
