Het vastketenen van Newey aan zijn tekentafel lijkt succesvol te zijn geweest.
Newey zou de problemen begrijpen volgens Marko. Een beetje komt uit stijfheid van onderdelen, maar er lijken ook aerodynamische problemen te zijn. In ieder geval met de gekopieerde Mercedes neus, maar waarschijnlijk met meer dingen. Er treed dus aerodynamische stall op en hoe langer de bocht, hoe erger het word. Wat ze dus nu gaan doen is updates een voor een introduceren zodat ze een referentiepunt hebben en weten wat werkt en wat niet.
Ook leuk is dat ze schatten dat Mercedes alleen uit de PU nu al 0,4s haalt en dat nota bene Renault een iets betere kwalificatiemodus heeft dan Honda. Dat is omgedraaid in de race waar de Honda beter is. Ferrari is prachtig gecrasht, aldus Marko.
Mercedes laat volgens RBR alleen wel echt alles zien bij hun eerste stint om gewoon keihard weg te rijden, daarna schroeven ze terug. Dat deed RBR dus niet in hun winnende jaren omdat ze dan wisten dat ze gestopt zouden worden door Ecclestone...
Where did the stall come from?
With these symptoms one reason is usually obvious. The aerodynamics are not stable enough. The downforce fluctuates depending on the driving situation, because the complex aerodynamic structure causes stalling. The longer the turn, the bigger the problem. The Hungaroring has many slow corners, but they have long radii.
In Austria Red Bull still suspected bends in the underbody. But according to sports director Helmut Marko, this is only part of the truth. "After all the investigations, we can say. the dog lies in the aerodynamics. Something about the airflow does not fit. Bending of the parts is certainly one point, but the airflow also breaks off for other reasons. For example, because the copied Mercedes nose was badly copied."
Star designer Adrian Newey believes he knows what's causing the problem. "We now know what works and what doesn't," confirms Marko. "From this basis we are continuing to develop. We try to correct the mistakes as soon as possible. That's why we no longer put all the new parts on the car in one piece, but one after the other, so that we can see if there is a mistake somewhere.
Red Bull and Honda's hands are tied on the engine. The scope for finding more power is limited. By now everyone has realized what a super engine Mercedes has built. Red Bull converts Mercedes' power advantage into a lap time of four tenths. GPS-measurements show that Mercedes has been able to increase power massively over the winter, Renault has a little more than Honda in the qualifying trim, while Ferrari has crashed magnificently.
In the race, Honda is a bit better off than Renault. Which is also no consolation in view of what Mercedes is unpacking in terms of power. Lewis Hamilton and Valtteri Bottas try to drive the competition to the wall right at the beginning of the race. "Until the first stop, they drive the engine in a sharper version. Then they go back", Marko knows.
The victory of the mechanics
Red Bull is not just about quick reactions now. The next stop is Silverstone. There's a good chance you'll take another beating. If there's one track that's cut out for the Silver Arrows, it's Silverstone.
That's where Red Bull says it has Racing Point to fear. The copy of last year's car is based on the same genes. Marko is not worried about the season. "We should be stronger there. They can't use the speed from qualifying in the race. And they're not strategically ready yet either.
Red Bull's view is that the finish line should still be Mercedes. That's why the lights aren't going out in Milton Keynes right now. "We are investigating and checking in every direction how we can get to Mercedes," confirms Marko.
We don't want to get bogged down in small projects, but rather examine what is still possible within the limited development opportunities. "That's off the table for now. We have to sort out our suspension problems first."
Which Marko is surprised: "Why does Mercedes so openly demonstrate its superiority? In our good years we didn't try to drive away so blatantly from the front in every race. The Mosley and the Bernie would have slowed us down immediately. Which happened enough times."
Right now, Red Bull is celebrating its small victories. For example, the masterstroke of the mechanics' crew to change a handlebar and a strut on Verstappen's car on the grid in 12 minutes. At first, even Marko no longer believed in the miracle.
"Then the man in charge assured me that it would work out. The boys worked with incredible precision and speed. Every move fitted. We still had to swap access passes among the mechanics because not all of them had the authorization for the starting grid. For example the specialist who uses a scanner to check the carbon parts for damage. What was achieved there was unbelievable. There are still strengths in our team."

Tenzij je een Mercedes fan ben, tja we are all screwed.
Maar er is ook goed nieuws. We krijgen volgend seizoen nieuwe banden die minder snel oververhit zouden moeten raken en beter om zouden moeten kunnen gaan met veel neerwaartse druk. Please don't be even worse want dit probeerde ze al voor dit seizoen, maar die banden zijn unaniem afgekeurd door alle teams. Dan weet je het wel...
Pirelli has developed new tyres for the 2021 season. To test the prototypes, the Italian engineers have reserved two 30-minute slots for the race weekends in Silverstone and Barcelona.
Actually, it sounds unnecessary. The cars' regulations remain stable for the coming season. So Pirelli could simply continue with the rubbers of the current specification. But in Milan, there are fears that the teams will be able to improve their cars quite a bit despite the almost complete freeze of technology.
At the beginning of 2021, however, the load on the tyres should first decrease. With changes to the underbody, the regulations artificially brake the cars. "For the end of the coming season, however, we see the danger that the downforce levels will rise again, so we want to be prepared for this with the current tests," explains Head of Sports Mario Isola.
In the tightly scheduled schedule, there is very little time for extensive testing. In the past, the Pirelli teams had to make their cars available on a daily basis so that the supplier could test new products in practice. Now the engineers only have short slots to collect data.
Tyre test in free practice
Pirelli has agreed with the teams that 30 minutes of driving time will be reserved for tyre development during the second Silverstone weekend and the second free practice session in Barcelona. According to the regulations, all 20 drivers must participate. Exceptions are only made in case of technical problems.
Pirelli wants to have various prototypes bolted to the cars. The tyres are unmarked. This means that not even the teams' engineers know what kind of compounds are involved. Pirelli also determines the duration of the runs and how aggressively the drivers should gas. The drivers then simply have to unwind the given programme.
"We want to try out a few different variations. We've focused on stability in particular. This means that the new tyres also work at lower pressures. There are new solutions to alleviate the problem of overheating," says Isola about the planned improvements.
Second attempt for new tyres
The prototypes are only fine-tuned and not completely new tyres with a modified substructure. "You can't do much development work in half an hour. It's just a matter of validating the simulations," Isola explains. "If we get good data, then we want to finish the further development for 2021 right away. There should be no more testing this year."
It's not Pirelli's first attempt to prevent the premature overheating of the tyre surface. Last season, the Italians had already developed prototypes that allowed the drivers to go full throttle for a longer period of time. However, they failed at the Abu Dhabi tests after the season. After unanimous rejection by the teams, Pirelli had to repack his newly developed tyres and continue with the old specification.
"The new prototypes have nothing to do with the tyres originally scheduled for 2020," explains Isola. "In the case of the tyres, we had also changed the outer tread pattern at the time, which required a larger recess in the underbody. To try something like this by means of a 30-minute test during a race weekend is not possible. But we have learned from the data of that time. ...and we're applying that knowledge to the new prototypes."

Never argue with an idiot. He will drag you down to his own level and beat you with experience.
