Post from Mika’s Instagram stating he has no knowledge of any agreement between Ferrari and the FIA, and that it was a throw away comment based on media headlines.

I won't say much on Salo's comments; Despite him racing for Ferrari in the past, I find it very hard to believe he'd have access to that sort of inside information...

Exactly, and even if (and that's a big IF) he had access to the details of the agreement, i highly doubt he would disclose details in such a manner considering that afaik he's still on the list of FIA stewards and would potentially even make himself open to lawsuits.

Isn't it more likely that this is his own interpretation based on the very limited information that is available?

And technically it's a very short and simplified version of what supposedly happened: they exceeded the fuel flow, had to lower the fuel flow thus ran the engine in a non-optimal way and are now back to fully utilising it sans trickery.

I do not think that this is the point. If they tricked the fuel system, this was an extremely precise trick. There is no reason why such a precise system would give them less fuel if they tune it to normal behavior.

I am more puzzled now by the symmetry. If I think back to 2019 how Ferrari passed other cars or could defend on the straight was quite similar to how cars passed Ferrari in 2020.
Furthermore Alfa and Haas gained, but was not directly to punish...

So my interpretation is a hidden penalty. The FIA found out, that Ferrari is using like 3% more fuel flow. So they restricted Ferrari engines by 3% in 2020.

For some reason I find this very unlikely, Ferrari was not directly cheating but sort of working around the rules (which happened several times in the past by other teams as well) so if I were them I would have never accepted this kind of penalty.

What in my opinion is more likely is that the complete system (like turbocharger and MGU-H size) was optimized for the higher fuel flow and therefore power, which was sub-optimal for lower fuel flow and power. This is sort of confirmed by the rumors that the new engine will be equipped with a smaller turbine, which might work better with the lower fuel flow to extract as much energy as possible from the exhaust gas.

Enrico Gualtier 2021 engine:
"On the internal combustion engine we have continuously worked to try to increase the degree of thermal efficiency of the engine itself together with Shell. This led to an estimated advantage of over a tenth of a second in lap time. We worked a lot on the turbocharger, on the power supply to follow the engine's needs, and on its efficiency part, to increase the recovery of energy from the exhaust gases “

These are the first pictures of a Ferrari PU (released by Ferrari) since 2014, I believe:

I can't find matching pics of older engines, this might actually be the 2020 one..?
Only last year Ferrari had this very straight exhaust manifold

Yes it's the 2020 engine

Thanks @Blackout the second pics confirms it.
The intercooler is smaller and sits a bit lower.

2020


2019

But I'm sure the Ferrari compressor is inside the V... similar to the 2015-2016 Honda, but closer to the rear.

FERRARI TURBO-MGU-H set-up was never similar to what Honda used, neither back than nor now, this because Honda always used a ‘split’ turbo with MGU-H in between turbine and compressor, while FERRARI always placed the MGU-H in front of compressor.

In 2015 the Honda turbocharger and MGU-H were located inside the ‘V’ of the engine, with Honda like Mercedes having a ‘split’ turbine from compressor, but Honda used an ‘axial’ flow compressor, the inlet plenum was placed on top of turbine and compressor, with the variable-length intake trumpets turned 90 degrees to lower the height of the plenum chamber.

The Ferrari is smoking again, like in 2018.

At the red bullies they would have noticed that and noted it as a future item.

And stopped after 4 hours of running with not too many laps, unlike 2018.

Is it PU related? I've not heard anything yet.

Did you hear it? Sounded like misfiring.

They did complete 59 laps, which is more that what some other teams did so its chill still
