Any reference to this? This is the first I hear about it.Tzk wrote: ↑11 Apr 2019, 23:34Regarding the fuel:
Have the rules changed regarding the fuel spec btween different teams? Afaik last year ferrari used some special fuel which they offered to haas and sauber, but both teams declined the offer because the fuel was too expensive.
I guess that they do the same this year and hence the ferrari smells different to haas and sauber.
They don't have to use the same fuel. Renault uses Castrol, McLaren is Petrobras.Tzk wrote: ↑11 Apr 2019, 23:34Regarding the fuel:

I read this in a motorsport.com article last year. Iirc in the 2nd half of the season. Might have been gunther steiner who mentioned this, but im not 100% sure about him mentioning it.mzso wrote: Any reference to this? This is the first I hear about it.
Many aspects of the engine are designed in close collaboration with the fuel supplier, switching is not so simple, what sometimes happened is that when a team switched from petrol supplier A to supplier B, the latter just buyed the fuel from supplier A and rebranded the drums, tanks, filling gear, etc. At least that's how it used to be, remember that, after all, it's about bussines...

Power deficit difficult to make up
Some excerpts:
"Mercedes has observed a power explosion in the engine at Ferrari in Bahrain. Ferrari insists that air resistance (drag) plays a major role. Who is right? We asked around in both camps."
"Team boss Toto Wolff put the proportion of air resistance at a maximum of one tenth. This would give three tenths of the engine power. His colleague Mattia Binotto thinks this is exaggerated: 'I looked at the Mercedes rear wing. They drove in Bahrain with clearly more downforce than we did.' For the Ferrari boss, air resistance therefore plays the decisive role."
"Binotto also explains this by comparing Ferrari and its customer teams. HaasF1 did much worse on the straights than Sauber. The Swiss would have shown a very similar speed profile on the straights as the factory team. HaasF1 on the other hand lost six tenths. It is known from HaasF1 that they were on the road with a lot of downforce."
"The Mercedes engineers don't want to be blinded by the theory of drag. 'Ferrari was much faster than us in both [DRS and non-DRS] conditions. That's why the drag factor couldn't have played a big role.'"
"According to Mercedes, the difference between Ferrari and its customer teams can also be explained by the fact that the factory racing team drives with a different specification of petrol and oil. "
"Mercedes wants to watch in Shanghai whether the pattern shown in Bahrain repeats itself on a completely different type of track. "
Document 7 from the race, released by the technical delegate, show that VET, LEC, MAG, and GRO all took new CE and will start the event with it.saviour stivala wrote: ↑15 Apr 2019, 10:06Five out of the six FERRARI engine cars were using the old type of CE in China.
They reverted to the old spec but had new units fitted so will have 1 old spec and 1 new spec for the season. This surely isn`t the Mclaren supplied unit which all the teams use [or is it?] as I was under the impression that was a standarized part which all teams must use.subcritical71 wrote: ↑15 Apr 2019, 13:11Document 7 from the race, released by the technical delegate, show that VET, LEC, MAG, and GRO all took new CE and will start the event with it.saviour stivala wrote: ↑15 Apr 2019, 10:06Five out of the six FERRARI engine cars were using the old type of CE in China.

Very confusingFerrari have chosen to introduce - ahead of schedule - the new TAG-310B ECU control unit that will be used in 2014
Yeah, when I mentioned 'new', I was meaning new in regards to their allotment for the season as that is the only thing reported by the FIA.Mattchu wrote: ↑15 Apr 2019, 13:48They reverted to the old spec but had new units fitted so will have 1 old spec and 1 new spec for the season.

Edit:
Seems that the latest McLaren/TAG powertrain control unit is the 320, maybe Ferrari introduced a newer unit ahead of schedule and it has some gremlins.
