Zhang Yifei thought of many possibilities, but he didn't expect that Cosell's answer was so simple, that is, he ran fast...

Although Kossell said that, after he actually turned around and asked Yamamoto Ukyo behind him: "Ukyo, does Toyota have hand-carved wetland tires?"

"No, they are all Renault-style wetland tires."

The real F1 wetland tires, the tire drain patterns on them, were carved on the tires by engineers from the fleet, and took one to two days to a knife.

Because the road conditions of each track are different at that time, the requirements for wet and wet patterns are different, such as the depth of the pattern, pattern interval width, etc.

The slight differences in these pattern formats will have a great impact on tire displacement and grip.

Generally speaking, each tire will have four main patterns, just like ordinary household tires, there will be several main patterns. The depth of these four main patterns is between 2.5mm and 5mm.

In addition to depth, the standard requirement for the spacing between these four main patterns is 50mm. As long as this standard is met, some other small patterns can allow team engineers to perform freely.

Therefore, when encountering heavy rain or severe internal water, the team engineers will deepen the tire patterns and carve more small patterns outside the four main patterns to speed up drainage.

The more lines, the deeper the displacement, the greater the displacement, but the corresponding one is that the tire grip decreases and the slower the speed. If you don’t choose this way, the car may slip due to too much water accumulation, which is more dangerous.

For the F1 event, the gap between zero points and milliseconds per lap may be the time to determine the key points of the victory or defeat. The machine has standard tires, and the pattern standards and depth are fixed, and it is impossible to adapt to local conditions.

In order to ensure the absolute matching of the wet and dryness of the track, racing engineers need to match the more suitable tire patterns and depth, and hand-carving becomes the only choice.

But Renault is just a primary equation, and such labor costs are not something that individual paid drivers can afford. Even if they sign a contracted team, they cannot reach this level.

Toyota only provides primary technical support, which is obviously beyond the specifications. They cannot spend a lot of money on a youth training student, so naturally there is no wetland tire with hand-carved pattern format.

When he heard this answer, Cosell frowned, but he didn't say anything.

Indeed, the competition level of Formula Elementary does not meet this high requirement. I can only say that I have habitually arranged tactics according to the F1 standard.

"Teacher, the Renault-style wetland tires have the shallowest traces. Generally, there is no problem with wetland drainage, but when the road area is encountered, the water may slip. Should I replace it with a safer full rain tire?"

"What is the depth of the pattern of the full rain tire."

“5mm.”

"5mm is too deep, and it is not raining now. The depth of the pattern may be one to two seconds slower than the lap speed of the wetland tires per lap."

Kossel is rarely in a state of hesitation. The track is not very wet. It is just because of the special environment of the boulevard that some areas have accumulated water.

If everyone uses full rain tires, it is naturally no problem, but if someone chooses ordinary wetland tires, then the tire gap of one to two seconds per lap is likely to be unable to be recovered unless the strength gap between the two sides is particularly large.

"But the instructor, in addition to the ground area, there is also a lot of water accumulation on the forest leaves. Once the car passes through at high speed, the airflow fluctuations and noise vibrations caused by the car will cause the water droplets on the leaves to drip, and the water accumulation on the track may further deteriorate."

"So I think it's more suitable for using full rain tires for safety reasons."

Yamamoto Ukyo is a data analyst. After experiencing the last tire blowout, he has been more strict with himself, and has basically figured out all the competition data of the Hoganheim track over the past decade.

It can be said that the Hoganheim Raceway, because of the existence of the forest section, is the most complex branch of all Formula tracks, full of variables, which tests the team's pre-race plan very much.

It is precisely because the road information is too complicated that the Hoganheim Raceway was directly cut off when it was renovated in 2002, and another challenging track has become mediocre.

Cosel listened to Yamamoto Ukyo's suggestion, held his hands in front of his chest, staring at the track ahead, and did not nod directly to agree.

He actually knew the risk of water dropping in the tree-shaded section. He had once experienced a racing accident due to changes in the tree-shaded course of water accumulation.

But the question is, should we choose mediocre to ensure safety, or risk our victory?

If Cosell was Zhang Yifei's real competition engineer, he would choose wetland tires without hesitation just like the previous conversation. Mediocre safety has never been his style.

But now Cosel is only a "temporary" and everyone is not a real racing team. This kind of life-threatening choice, with his current identity, is really hard to help Zhang Yifei make a decision directly.

So Kossel hesitated for a moment, looked at Zhang Yifei and asked, "Do you choose wetland tires or full rain tires in this competition?"

Zhang Yifei stood beside him when he talked to Yamamoto Ukyo, so he naturally heard it.

Since he is the party involved, Kossel wants to hear Zhang Yifei's own thoughts on this kind of thing.

“Wetland tire.”

"Why?"

“Run fast.”

Hearing this answer, Cosel opened his mouth and swallowed what he wanted to say.

Soon, the old German man, who had always been serious, began to rise slightly.

At this moment, he truly felt that Zhang Yifei was the same type of person as him.

At 3:40, the main race at Hoganheim Station began. The event command center issued an order and all drivers entered the departure preparation area through the maintenance channel.

This time, Zhang Yifei was the first to come out of the maintenance station and parked in the parking space in the departure preparation area, which is commonly known as the pole position.

Seeing Zhang Yifei's racing car parked in the pole position, the audience gave out bursts of applause and cheers, and even a few red flags appeared in the audience. Today, Zhang Yifei's supporters have improved several times compared to the qualifying stage.

You should know that during the qualifying competition, even if Zhang Yifei's popularity and popularity have increased certainly after various media events, those are not proof of strength, but they are more like a "hype" popularity.

Deborah, Shanghai, can only be regarded as a small town in Germany. It is a rare scene to have more than 100 Chinese and overseas Chinese supporters.

As for today's situation, Zhang Yifei estimated that there would be two or three hundred people. Although this is still a small part of the total number of 12,000 viewers, Zhang Yifei was already very satisfied, at least he was not fighting alone.

Parking on the pole position, Zhang Yifei stretched out his arm and waved to the audience area. This is the honor that only "winners" have. When the qualifying match was far behind, Zhang Yifei was embarrassed to wave.

His actions made the cheers in the audience even more enthusiastic, and many foreign car fans even shouted the name "Fei".

"Look, Zhang Yifei parked in the parking space. I really didn't expect that one day, we Chinese drivers would get the pole position!"

"Depending on your prospects, what's this? He is a driver who can enter F1!"

"It's too early to enter F1 now. It would be great to win the Hoganheim Championship."

"How bold are people and how big are they? Do you understand?"

"Yes, there is no dream at all, so what's the difference between it and salted fish?"

The Chinese audience off the field were very excited. After all, this was the first Chinese driver to get a pole position on the European track.

However, soon there was a more intense cheering sound on the track. This situation made Zhang Yifei look at him subconsciously. Masa was driving his No. 3 car and parked behind Zhang Yifei's right.

During the qualifying race, although Masa had a crash, the race progress had exceeded 75% at that time. According to the FIA ​​regulations, it can still be considered to be a valid finish.

Moreover, the fastest lap in the qualifying competition was seen, and Masa still won the second place in the qualifying competition with a time of 1 minute, 47 seconds, 172.

In the accident yesterday, due to the final emergency brake and the protection of various protective equipment, Masa was only slightly injured and did not affect today's main competition.

But no matter what, after experiencing such a racing accident, Masa still appeared on the track the next day, and this spirit deserves the audience's applause.

Not to mention that Massa itself is the most popular driver in the 2000 European Cup in Renault. His crazy chasing record on the track has also won the respect of many car fans. It is not surprising that such enthusiastic cheers are today.

It seems that my audience base is still much worse.

Zhang Yifei muttered, he was not envious of Masa, but just a simple sigh.

The third pick is Kubica, who scored 1 minute, 47 seconds, 319 in this qualifying match, and the track record is only 0.002 seconds slower.

It can be said that in yesterday's qualifying match, many people held their breath and wanted to get pole position to prove themselves. Under this competitive pressure, the overall performance has been exaggeratedly improved. If it is placed in Monza Station, Kubica can get pole position at such a speed.

The fourth place is not Suarez, but a player that Zhang Yifei had not noticed before, named Scott Dixon, who was behind Kubica by a very narrow gap.

The appearance of this player surprised Zhang Yifei. He thought Suarez or Makina of Mano Racing would rush up, but was won fourth in the qualifying round by a player he didn't pay attention to.

Zhang Yifei glanced at these few eyes, in addition to looking at people, he looked at tires more. In addition to choosing wetland tires, Masa, Kubica, and even the fourth-ranked Dixon, he chose wetland tires instead of full rain tires.

It seems that everyone has the same ambitions and desire for a championship!

Just as Zhang Yifei was looking around, Masa also looked at Zhang Yifei, and the two of them looked at each other.

At this time, Masa raised his right hand and gestured a "1" gesture. His meaning was very obvious. He would win the championship this time.

Seeing Masa's movements, a playful smile appeared on Zhang Yifei's face.
Chapter completed!
