Ferrari is playing with the limit
Three-way fight at the top gets harder

Mercedes, Ferrari and Red Bull fight for every hundredth of a second. Some go to the limit, the other the risk is too high. We have some examples of how the teams use technology to reach their limits.

12.04.2018, 15:05 clock
The fight between Mercedes, Ferrari and Red Bull is becoming increasingly brutal. He does not only take place in the aerodynamic offices. The top three teams struggle for hundredths of a second in each discipline, and sometimes a seemingly small change can make a big difference. We'll show you three areas where the top teams in front of and behind the scenes are in high spirits. And almost always it's Ferrari who dare to go to the limit. That too is one of the reasons why the red cars are fully in the title race.


Normally the aerodynamic arms race makes the difference. But in the first three races you have seen only marginally new parts on the Mercedes F1W09, the Ferrari SF71H and the Red Bull RB14. Other things gave and decide why Ferrari is better than expected, Mercedes is not quite as good, and why Red Bull still can not play the qualities of his car like this. We have selected three examples:

The tires: thinner tread everywhere

Pirelli
Modifies
Tires
Thinner tread in three races
Mercedes had a problem in Bahrain. On a fast practice lap, the Super Supersoft rear tires became too hot. The drivers could choose where to lose their time. Either you let it go comfortably in the first sector with regard to the tires or you paid in the last sector for too much attack at the beginning of the round.

Mercedes has a luxury problem there. Pretty much downforce in the rear. This makes the rear tires strong and warms them from the inside. In addition there were difficulties to balance the cars perfectly for one lap. "We bring them great in the curves and not so good back out. It looks like the two ends of the car do not want to fit together, "Niki Lauda complained. The rough asphalt of Bahrain was an additional stress factor.

In the race the problem was gone. "Over several laps the temperatures stabilize. They are easier to hold in the window, "say the engineers. Mercedes knew since the winter test rides that the rear tires on certain routes could become a problem child. That's why Pirelli was brought to the attention, naturally with the ulterior motive that the tire manufacturer responds. What did he do?

For the races in Barcelona, ​​Paul Ricard and Silverstone, the tread is reduced by 0.4 millimeters. Because there was not the necessary support from the other teams, the FIA ​​stepped in with the security argument.

Of course, Mercedes would like Pirelli to extend the measure to all routes. Because every detail counts in the three-way battle with Ferrari and Red Bull. "If you really want to have two stops to improve your race, you have to go this way. With the current tires, we will have one-way races almost everywhere ", Mercedes builds an argumentation bridge for Pirelli.

Force India technical director Andy Green shoots immediately: "If Pirelli wants to make the gap between the top teams and the rest even bigger, they should do that. A thinner tread always helps those who have more downforce. Because then the rubber works less and heats less. "

Fuel and oil: fear of high consumption

Crisis meeting to
overcome the problem
Technicians reject suggestions
Fuel consumption has risen significantly in all this year. Because the drive units deliver the same amount of power despite the longer running times. And the cars have up to five percent more downforce. As a rule, this also means more air resistance. The top speeds have dropped compared to last year. This means more time on the straights, more time under full load and thus a higher consumption. The engine technicians have calculated that on the critical routes would need 109 instead of 105 kilograms to get through carefree.

So far it is not clear who is affected. Renault seems to hit hardest. The Renault drivers had in Melbourne even after seven laps under safety-car conditions to take the foot off the gas. In Bahrain even Honda made a better figure. Ferrari operated in Bahrain more lift and coast than Mercedes. However, an engineer from the silver camp warns: "We drove there most of the time in the slipstream. This helps."

Mercedes has another problem, you can hear under the hand. The cars with Mercedes engines are not as fast on the straights as they should be. This has supposedly to do with the oil specification. We hear that Petronas dug up a 2016 oil grade to be on the safe side with oil consumption. Until the beginning of the season, the oil consumption of Mercedes and Ferrari was only 0.01 liters below the permitted limit of 0.6 liters per 100 kilometers.

After the oil correction, Mercedes should be on the safe side when it comes to oil consumption. But that also costs power. Ferrari is apparently still full risk just below the pain threshold. And it benefits relative to the competition. No wonder that Mercedes engine chief Andy Cowell says: "In qualifying Ferrari and we are on par." So far, this was the domain of the Mercedes engine.

The oil theme could boil up soon. The opponents of Ferrari are trying to find out why the Ferrari engine in the factory car smokes so much when starting. And even when driving smokes more than the other Ferrari teams. Should not all engines of a manufacturer be the same this year?

Some suspect some trick behind that will allow Ferrari to add oil to the combustion process. Meanwhile, it is also known how the oil tricksters have practiced in the past. A gasket in the compressor of the turbocharger was carefully constructed "leaking" so that a pre-calculated amount of oil could enter the combustion chamber.

Wastegate helps aerodynamics

Riddles about Ferrari smoke
Why is it smoking from the rear?
The top teams send their spies everywhere. Since photographing the competing product in the pit lane looks almost antiquated. The top teams work with high-speed cameras, which show the vehicle in action in every detail. So Mercedes has discovered last year that Ferrari has forcibly controlled the passage of air through the front axle on the straights with a valve.

In Bahrain, Mercedes spotters have heard that the Ferrari engine in the cars of Sebastian Vettel and Kimi Raikkonen when accelerating significantly changes the pitch. Also in comparison to the customer teams HaasF1 and Sauber.

The resolution of the puzzle was not long in coming. Ferrari refrains in the qualifying rounds when Rausbeschleunigen on it with the MGU-H produce electricity to blow it over the wastegate valve to the rear wing. That makes a few points down, but better than nothing. In the qualifying rounds, the refusal to charge the battery does not bother, because it is already full at the beginning of the round.

Battery is a bad word for Red Bull. The first of two by Daniel Ricciardo is a case for the hazardous waste. Same damage as Max Verstappen last year in Montreal and winter testing. Ricciardo can figure out when he will receive a penalty for the first time. And that can not be offset with a few hundredths of the aerodynamics or the engine. Lewis Hamilton has already lost the GP Bahrain in the gear change.

Zaista bi trebalo uraditi nešto po tom pitanju.
Ne samo Australija, i u Kini je nedostajalo preticanja ( medju vodećima ), naravno, ne računam preticanja kad je razlika u gumama drastična.

Trebalo bi tu dosta menjati a ne samo aerodinamiku.F1 se pretvorila u trke-sezonu izdržljivosti.Svi nešto štede,niko ne vozi do kraja.Posle se čude šta je.F1 ubijaju debilska pravila.
PIRELI NAPOLJE IZ F1 !!!

Ali je aero najkriticniji. Kimiju bolid kao da je bio na ledu kad je bio blizu Botasa, bas se dalo primetiti koliko nema prijanjanja kad uslovi nisu idealni. Kladim se da je barem 20-30% incidenata na stazi prouzrokovano tim iznenadnim gubitkom prijanjanja.

Je l' može Merc da prošvercuje medium gume ? :lol:
Mislim da će Merc ove sezone ići na što tvrdje komponente koje su dostupne i što manje zaustavljanja.
Osim ako uspeju da reše problem.

Neznam zašto svaki put Ferari uzima velkki broj najmekših guma.....kada u trci rade isto što i Merrcedes, t.j. voze sa najtvrgjim gumama
