Concept power units from 2030

High RPM is wasteful and sucks for longevity. It's a last resort to increase engine power.

Obviously yes, but if your choice is to remove the turbo to get the noise back or to suffer more friction losses with forced induction, the choice is obvious from an efficiency standpoint. A turbo engine will always be more efficient.

Did anyone ever make a 18k+ reving turbo engine for a car (or anything really)? Is there any technical reason to have done that?

Maybe aircraft engines? But no it literally makes no sense to build turbo engines that rev that high, since you can get enough oxygen for combustion at relatively low revs. I guess you could harvest stupid amounts of energy from an MGU-H at 18 000RPM though, since you basically have no use for the turbo at such high revs. I guess an 18 000RPM turbo engine would be running with a fully open wastegate/harvesting MGU-H at 18 000RPM and would only use it at lower revs.

It would probably still be more efficient than an NA engine running 18k though, since you would be able to harvest with an MGU-H and benefit from the turbo at low speeds. But I have no clue if a turbo engine could even survive 18k with fuel flow capped at 100kg/h. I feel like it would basically be running so lean it would eat itself alive, and fuel flow can't really be increased without the engine power getting out of control. You would probably have to reduce the displacement in order to make it survive at 18k RPM.

(I have a very poor understanding of how an ICE works)

shame fuel cells don't work on fuel as we know it
we need a genuine glut of carbon-free electricity to make fuel cell fuel (genuine ie no carbon cost)

the plan of the powers that be .......
Joe Citizen goes BEV so tens of millions of batteries are available to store & support PTB's intermittent renewable electricity
this requires no new technology and no PTB expense
it also amounts to a priceless stabilising element in the electricity supply & demand

Fuel is formulated for use and not the other way.
Besides your statement is false, it does work with common fuels, from methane to butane for example. A typical end result of cracking, which is widely used.

As for PTB, I don't know why some people insist on using obscure and/or ambigous acronyms.

line 3 says 'powers that be '
line 4 says 'PTB'
line 5 says 'PTB'
can you guess what PTB stands for ?


regarding butane - it's much too valuable to be used as motor fuel
the likely application for the fuel cell is using methanol to decarbonise shipping
methanol made using the inevitable surpluses of renewable electricity
acting as an alternative battery - whether using a fuel cell or as fuel for an ICE

but F1 is expected to help planting approved ideas in the minds of masses ie car users
ideas like the virtuous inevitability of what is actually a battery so-called electric vehicle

The cars would sound much louder if they turned the defining PA and music mixer down. You would not need to have ear defenders on all the time then

Are there currently any other concepts or ideas for the next regulations from 2030/2035 onwards?

FIA people tend to toy with the idea of going for high revving NA V10s or V8s running on carbon neutral synthetic fuels, but the FOM and the teams won’t accept that, because it’s basically a technological dead end.

Basically we’re probably locked into the current path of less and less fuel until the cars become so slow that viewer numbers take a nosedive, at which point they will go for a more exciting engine concept.

I think so too. I believe all the talk about going back to naturally aspirated V8s is just some marketing.

And what’s your idea of an exciting engine concept?

Take the fuel flow and MGU-H from the 2014 regulations and put them in the 2026 engine. Raise the revs for max fuel flow from 10500RPM to like 12500 to get a more satisfying engine noise.

Remove the battery weight floor to get lighter batteries. Just generally loosen the exotic material bans and significantly reduce weight floors for engine components.

Personally i quite like the current engine formula. The biggest problem has always been that they sound absolutely terrible on tv, and I don't know whether it's just impossible to replicate how they sound in person on the broadcast or if FOM just haven't tried very hard to achieve it. In my opinion the v8's sound pretty terrible in person, it's just a wall of noise of noise which is of very dubious quality. Yes the V10's sound glorious, but the only way IMO we ever see a v10 again is F1 going all in on direct air capture derived synthetic fuels, and the FIA getting the cojones and telling the automotive manufacturers to get on board or get lost.

Wouldn't it be an option to switch to two-stroke engines? Possibly with HCCI ignition.

I think it's not without reason that Pat Symonds once suggested switching to two-stroke engines.
