Concept power units from 2030

Also, teh 2026 ICE will have (slightly) more power than LMP1 with lower fuel flow and lower energy density fuel.

There have also been hints by Nikolas Tombazis that, at their peak power, the PUs could exceed the power of the current PU by as much as 100hp, which would mean ICE power in excess of 600hp.

The "extreme fuel saving technologies" used in F1 gave extra power, not better fuel saving.

That's the same thing. It's just a matter of choice to go with more power or less fuel weight. It seems more power is more fruitful.

Not sure what your ultimate point is? That the 919 is not F1 level? That was never in doubt. Could it have been more powerful with the same fuel flow/quantity? No idea. Don't what other limitations might have been imposed on LMP1 engines, I'm not really familiar with them. Or whether all that recovered electricity made the pursuit of more ICE power of little interest.

So after reading this, it’s not if the V8 comes back but rather when.

I do not know how reliable AMuS is.

His reasoning for going the route of a V8 is curious, as he states part of that is having one dedicated supplier for the gearbox and one for the hybrid aspect. What's the actual goal, other than the engine simply being lighter? You won't be getting much innovation out of a single supplier providing for an entire field (not incl. ICE).

It’s not that the V8 is completely banned when I read the article, but more that Audi and Honda want to wait until the complete cycle is finished in 2031. They don’t want to move earlier to a V8 in 2029/2030.

And some details are still about whether it will have a turbo or not, and what kind of hybrid element.

So the plans for the V8 are not gone.

Though Audi still saying they want a high efficiency hybrid engine.

High efficiency would, surely, rule out any N/A engine?

Maybe they can compromise: give the teams a NA V8 but also with front-axle regen and an MGU-K on the rear axle. That way Audi gets what they actually wanted in the first place, front-axle regen.

Did Audi want front axle regen?

They wanted turbo engine withut MGUH and large ERS.

Actually, I don’t know that, but maybe front-axle regen is something that could tip the balance for the NA V8, a sort of compromise.

I suspect the ERS will be of less importance for a future PU than the 2026 PU.

So, less need for front regen.

In any case, one of the goals for the future PU would be lighter weight, which front regen woudl work against.

I don’t think so!

Toyota which has been the only car manufacturer producing fully hybrid cars always uses NA engines along with batteries and CVTs! So I don’t think NA engines mean low efficiency…

[saviour stivala]

Capturing exhaust gasses that will otherwise goes to waste and using them to benefit the engine will always increase engine efficiency.

Maybe that’s why they don’t have one foot in F1 (I mean with Haas).
