Boris_CRO je napisao/la: 24.03.2022., 21:40 Ova vijest što se tiče utrka je bogohulna. Koji će ti vrag 30 loših utrka? Bolje imati 15 klasika, nego 30 pustinjskih i gradskih gluparija. Što se mene tiče utrke kao Monza, SPA, Suzuka, Silverstone ili Sepang bi trebali imati stalno mjesto kao neki "core" iliti kostur kalendara i to BESPLATNO. Dakle da organizator ne daje niti eura u F1 nego samo u obnovu tih klasičnih staza. Zašto se prave pametni? Samo treba kopirati kalendar iz 2001. godine. Ništa više. Sve pustinjske utrke mogu "vužgati", sve gradske utrke mogu baciti u kontejner i naravno Tilkea naglavačke u prvi bunar. Jedini klasik bez kojeg bih mogao je Monaco, ostalo NE DIRATI.

F1 | Engines 2026: with 75kg of fuel, more electric power is needed
Porsche and Audi's entry into Formula 1 in 2026 will soon be made official, but the two German manufacturers have set strict conditions for their debut: power units will have to cost 50% less than today due to the abolition of the MGU-H and fuel consumption will have to drop dramatically. But no one has yet said how the lost power will be recovered to reach the approximately 1,000 horsepower of the current units.


The VW Group board is expected to approve the entry of Porsche and Audi into Formula 1 from 2026, but the two manufacturers will have to be active in advance of that date, the former taking over Red Bull Racing and its Powertrain subsidiary, while the four-ringed brand should link up with McLaren, which would give up its current supply of the Mercedes PU.

The arrival of Porsche and Audi in F1 is conditional on the approval of the technical regulations that will define the 2026 power units with two declared objectives: to reduce costs by up to 50 per cent of the current ones and to reduce emissions in order to push the GP engines towards carbon free with ecological fuels.

Formula 1, then, as a useful tool for the automotive industry to point the way to an alternative to electric cars, which is more complicated than the legislators themselves thought in terms of achieving the targets set for 2030. So many certainties that seemed to be set in stone in the name of ecological transition seem less within reach, and the events of the war in Ukraine are rapidly changing important scenarios that could change the general picture of mobility.

Having said all this, it must be said that the German manufacturers had made one condition for their entry into Formula 1: to abolish the MGU-H, i.e. the electric motor-generator that collects energy from the turbo and transforms it into electricity to be stored in the battery.

Mercedes, Ferrari, Renault and Honda have spent staggering amounts of money to develop this recharging concept, which, however, has not been reflected in production cars except for the Mercedes One, the star's hypercar presented at the 2017 Frankfurt Motor Show and produced in a limited edition of 275 models, but which has never been seen on the road because five years later deliveries have not yet begun.

Porsche and Audi, therefore, imposed the elimination of the MGU-H in the 2026 power unit, aware that the new units would have had enormously lower research costs, being able to enter F1 with a different technical concept that would not benefit the Manufacturers who are already there.

Obviously Stefano Domenicali, F1's president and CEO, has been championing this cause, because the entry of two such prestigious engine manufacturers could be the feather in the cap of his management. So far, so good, but the FIA World Council's decision on the 2026 power unit regulations has been delayed.

Why? The reason is quite simple: the Germans have called for a drastic drop in fuel consumption. They're talking about dropping to 70-75 kg of fuel, compared with the 110 kg of petrol they currently store in their tanks.

The objective is certainly very challenging and would push research towards endothermic engines with extraordinary efficiency (current PUs have exceeded 50% on the dyno) that would literally bring down consumption, but the unresolved question is how you can get to a power unit with almost 1,000 horsepower with 35 kg of fuel less and without the MGU-H.

The question is splitting the table at which the CEOs of the manufacturers concerned sat: if the impact of the endothermic engine is reduced, 350 kW are badly counted: a real enormity! Not least because it is not yet clear how this gap is to be made up. It should come as no surprise, therefore, that there has been a halt to research. A decision will have to be made by June, but the feeling is that they still want to gain time.

One solution could be to increase the capacity of the batteries: that's certainly feasible, but the main drawback is the weight that the current F1 cars already struggle with, since they can't reach the 798kg limit allowed by the FIA. If we don't want to see "buses" running, we'll have to look for other ways to find power.

And what if, in the end, the gain in time benefits the new manufacturers? Is there any fear that they might come up with some ideas that follow on from the technologies they have already experimented with in other categories and gain a competitive advantage, as Mercedes did scientifically before launching the hybrid era in 2014?
