Hi mizarbarym, welcome to the forum.
That article is in italian, please be kind enough to add a few sentences of english summary or the 2-3 main points, in english. Thanks.
English translation, it's a bit rough but you can get the gist of it.
Background: Why can Ferrari introduce a revised Power Unit in various components?

All that remains is to wait. The introduction of the new Ferrari power unit is lacking less and less, which should represent an important upgrade . A card to play both in the fight for third place in the current F1 championship , and as a basis for development for what will be resolved at the beginning of 2022 , a moment that will mark the substantial freezing of the engines until 2025 or, in the worst case scenario, until to 2026. The debate on the date is still ongoing ( read here to learn more ).
What technical improvements will the Maranello engineers presumably bring to Sochi over the weekend of 24-26 September? We gave you an account yesterday in a specific study that reveals the secrets of the revamped V6 ( click here to find out all the details ). This article, on the other hand, aims to answer another question of no secondary importance:
F1- Why, in a situation where developments are frozen, Ferrari, unlike other engineers, can allow itself to make various and significant changes to its hybrid turbo engine?
We see…

Let's take a step back to the 2020 season when, due to the financial crisis caused by the Covid 19 pandemic , a sort of regulatory freeze was introduced. Which, however, is not total. Indeed, the term freezing is incorrect. Rather, we should talk about homologation rules that block specifications at a given time of the year . In the long winter break at the beginning of 2020 , the parts subject to "block" were defined: the internal combustion engine (ICE), the turbo, the MGU-K, the MGU-H, the electronic control unit, the batteries that accumulate the energy, the exhaust system, the oil circuit and the petrol circuit.
The homologation of these areas was immortalized in July 2020, when the season began. So, how is it possible that Ferrari can present significant innovations? The rules state that MGU-K, electronic control unit and battery packs could be modified between 2020 and 2021. While all the other parts (ICE, turbo, MGU-H, exhaust system, oil and petrol circuit) they could be renewed in 2021, at any time starting from the end of 2020 throughout the current championship.
Ferrari, which had introduced the second seasonal power unit in Baku, still used deliberate elements in the past season . He now has the opportunity to bring news to those areas he had left immaculate . Of course, at Maranello they do not unbutton them and do not say which elements are subject to revision. But, probably, on the basis of information collected by us, we can say that the innovations will essentially affect two areas: ICE and the hybrid part .

Let's start with the endothermic . Ferrari technicians carried out targeted work on the internal components of the ICE . The more or less declared objective is to increase the efficiency of the combustion chamber leading to a marked decrease in consumption . On the hybrid front , on the other hand, the aim will be to improve the ratio between energy generated and that spent over a lap.
This is one of the aspects on which the Maranello V6 is most deficient compared to the competition, with Honda and above all Mercedes representing the reference point. The current problem is that the electrical part is also used to compensate for the deficiencies of the endothermic part . So the riders can count, in the single lap, on less time of use of the hybrid's maximum power. The new specifications should solve - partially and totally we will understand it only in the course of construction - this kind of problem .
What Ferrari will introduce after Monza will also be decisive for the future as what will be resolved in 2022 will remain constant until the end of 2025 and the only possibilities for modification will depend on overcoming any issues relating to reliability. Not a simple process because any upgrade will have to be screened and approved by the FIA . There is not much time available which is why the Racing Department headed by Mattia Binotto ( read here the latest considerations on the Swiss) played the card of delaying some developments that could have been introduced before the world championship began.

In fact, next year, on March 1, the following elements will have to be resolved which, we recall, will last between three and four seasons, depending on what will be established in the coming months: ICE, turbo, MGU-H, exhaust, hydraulic system and fuel system . There will be more time, precisely until September 1, 2022, to bring the definitive versions of MGU-K, batteries and electronic control unit .
It really should be said that the future is today . In Ferrari they cannot afford any missteps because in Russia (even if there is no official confirmation, ed. ) The foundations are being laid for the next four years. And arriving late would mean paying a performance deficit that cannot be bridged until the presentation of the new drive units whose characteristics are still the subject of extensive and heated discussions.
