Are we realistically going to see new PUs in 2030? That would mean the 2026 ones only last 4 years. I feel like the teams will be reluctant to throw their years of R&D away after only 4 years?
Is the idea that the carryover from 2014 to 2026 will make the teams more willing to go to a completely new layout in 2030, since the 1.6L V6 will be a 16 year old layout by then?
I'm pretty sure the 2030 comes from an off handed comment by an F1 exec (stefano domenicali iirc). I think there's practically a zero % chance we see a new engine concept after only 4 years, unless the 2026 regulars prove to be disastrous for viewership (but i think f1 viewership and mandated engine concept is only weakly correlated).

I'll watch the first race of 2026, and if the engine regs cause bad racing, I will walk away until the next engine cycle.

Not to mention that there is always the option of throwing a bunch of fuel flow at the issue, should the engines prove way too weak.
If for the upcoming regulation changes they had chosen the V4 configuration, would this have made a difference in the RPM?
Because I think that if they want to achieve the same power with 2 fewer cylinders than with 6 cylinders, the engine would need to run at a higher RPM, right?
a 1066cc 4 cylinder engine would have to run (correspondingly) much faster
a 1600cc 4 cylinder engine wouldn't have to run much faster
SACI might not work much faster
They are aiming to reduce the ICE power by 1/3.
A 1066cc V4 is 1/3 smaller than a 1600cc V6.
So they target power could have been achieved by going to the V4.
There may have been some reluctance on the part of new manufacturers as the existing manufacturers would have been able to continue with their current combustion concepts.
As with most of his videos there is lots of technically incorrect stuff (lever arms and torque for example) and lots of technical drawbacks ignored (sealing, combustion chamber surface area).
High surface area to volume ratio is a major negative to combustion efficiency.
At the moment of combustion, the surface areas seems pretty low to me.
The higher the boost pressure is it will result in higher volumetric efficiency which in turn reduces the amount of fuel needed for the combustion process.

I think we'll probably see tweaks to the PU regulations after 4 years. If they were to make a wholesale change it would either be due to the new regulations being a disaster or to use new technologies like solid state batteries.
I wouldn’t be surprised if in the future they decide to go with the V4. It’s similar to the size of their tires. I once heard in a podcast that as early as the mid-90s, they wanted to switch to 18-inch tires because the existing ones weren’t road-related. And now, since 2022, we are indeed using 18-inch tires.
Some time ago, Domenicali said that in the future they want louder engines, but sound is wasted energy. The combustion engine is far from dead (as can be seen in Volvo’s decision to continue producing combustion engines after 2030), but the fuel they burn should be used as efficiently as possible and not wasted on noise. Especially with e-fuels, which currently require an energy-consuming process to produce, the available e-fuel should be used as efficiently as possible. That’s why I think in 8-10 years, we might see the V4 with some sort of electric turbo, and unfortunately, no V8.
Aren’t they already using solid-state batteries? If not, I definitely see them being used in the future. Perhaps even structural batteries, not in the chassis itself, but designed in such a way that the battery contributes to the chassis’ strength. This, combined with a light, powerful electric motor that could deliver around 30-40 hp per kg.
