Kossel believed in Zhang Yifei's emergency response ability. This kid rushed out of the runway due to tire grip problems in the first lap.

In fact, there were many emergencies later, but they were eventually saved by Zhang Yifei. It can be said that this kid can maintain extreme calmness in the face of crisis and minimize safety risks.

When Zhang Yifei ran to the 30th lap, his fastest lap speed had reached 1 minute, 24 seconds, 962, almost 0.4 seconds ahead of the Manicur Track record. This is definitely an amazing result. In history, all the drivers who can reach this level have entered the f1 field later.

There is no doubt that Zhang Yifei's current strength, even if he does not rely on the opportunity of the Prost team, he will be able to enter the F1 team in the future.

But no one can determine how long this time will take. Especially for a Chinese new driver, it will be more difficult to get the strength of the entire European racing circle and must have better results than other drivers.

When Cosell heard this lap, his serious expression finally faded away, and a faint smile appeared on the corner of his mouth.

The result of 1 minute, 24 seconds, 962 has reached the standard set by Kossel.

Of course, this is not the standard for the F1 driver mentioned earlier. If a top active F1 driver is really asked to drive, he should be able to lead the current track record by nearly 1 second.

The difference between 0.4 seconds and 1 second does not seem to be very big, but you should know that any track record improvement will be more difficult as it goes to the back.

Therefore, the difference in difficulty is far from being as simple as improving for half a second, but it is increased in geometric multiples.

"Teacher, Yifeijun has really reached the limit!"

Yamamoto Ukyo couldn't help but say that this kind of improvement speed was something that no Asian driver could do before, and even European drivers, few people could achieve the current crazy improvement of Zhang Yifei.

Judging from the surveillance screen, Zhang Yifei danced on the sword many times, and any 0.1-second increase is possible behind the track.

Even if there will be no major safety accidents in theory, who can confirm some things? If you really encounter a height difference and make the car roll, the consequences will be unimaginable.

The reason why Senna died back then was that a piece of metal flying out of the hanging directly pierced his helmet.

At high speed, a small piece of debris can be as fatal as a bullet, and no one can really guarantee safety.

"Um."

After hearing this, Cosell nodded slightly. It was indeed Zhang Yifei's performance and level of hard work on the track that was recognized by Cosell.

Even if you use the standards of a F1-level driver to ask, Zhang Yifei uses his best efforts to achieve his goal. With this result, as long as there are no major mistakes in the official competition, it is guaranteed to get the pole position and break the track record.

Even if other drivers also broke the track record, Kossel didn't believe they had Zhang Yifei!

This does not mean that Kossel is biased towards his own people. On the contrary, he has higher requirements for Zhang Yifei, but he is strict and harsh. Kossel never thinks that Zhang Yifei is weaker than other drivers. The 0.4-second gap is the performance of the strongest Renault driver in this class and the city!

Many times, Cosell didn't ask Zhang Yifei to challenge other drivers. What he wanted to challenge was actually himself!

"Fly, go back to the repair station and prepare for tire replacement."

At this time, Kossell used the fleet call system to issue an order to enter and change tires.

Now Zhang Yifei has run thirty laps, although the length of the Manicur track is almost three kilometers shorter than that of Monza and Hoganheim who have run before.

However, the total length of thirty turns is still close to 130 kilograms, and the grip of the soft tire has exceeded its peak at this time. In order to make the corner faster and ensure safety, it is necessary to enter the station to change the tire.

But the instructions issued by Kossel made Yamamoto Ukyo a little confused. He did not replace the conventional soft tires he used before, but replaced the super soft tire with stronger grip!

"Youkyo, you are responsible for the front jack."

In Formula Elementary Cars, there is no detailed division of technician team, but in the F1 technician team, the technician responsible for front and rear jacks is called "jakholde", which means jack bracket.

Their job seems very simple, but because they have to stand at the front of the car, the position is quite dangerous.

If the driver cannot accurately control his speed and stop accurately, the 80km/h repair channel speed is enough to knock the "jack bracket" standing on the front of the car away. This kind of accident has also occurred in f1 history.

Especially for a rookie like Zhang Yifei who has not yet come into contact with F1 racing trains, it is even more dangerous. It just depends on Zhang Yifei's buckle on the brake distance of the racing car.

Kossel handed over this most dangerous position to Ukyo Yamamoto, which was his trust in his students.

Similarly, Yukyo Yamamoto did not hesitate at all. He picked up the jack and waited in front of the repair parking space. This was also his trust in Zhang Yifei's driving skills.

While waiting, Yamamoto Ukyo couldn't help asking: "Teacher, are you really sure to change to super soft tires?"

"That's right, it's just super soft tires. There's not much time left for the track to rent. If you don't have enough staff, move faster."

Kossel urged, not caring about the tires at all.

You should know that the official F1 tire changer has a team of technicians with up to 17 people. Each tire is collaborated by three technicians, so that four tires can be replaced in just 2 seconds to allow the driver to leave the station and continue the competition.

Now, Zhang Yifei's team, plus Yamamoto Ukyo, a data analyst who should have been in the strategy group, has only three people who have made up the numbers, and the number of people is not the same order of magnitude.

Although the test run is not like a formal competition, and it is a race against time, the track rental time is still limited, and there is not much time left. Kossel also wants to test the wear level of super soft tires on the Manicur track.

After hearing the instructor's words, Yamamoto Ukyo's questions could only be suppressed. Super soft tires are not used very frequently in the current Formula competitions, because due to the development of rubber technology, super soft tires are really not wear-resistant.

Only in some slow and multi-bend tracks, which require extremely strong grip support, can tire types such as super soft tires be used, such as Moroccan stations, Hungarian stations, etc. in the F1 Grand Prix.

These tracks have their own distinctive characteristics. Morocco stations are used to use ready-made streets, with narrow roads and many bends, and they are not fast. They require extremely strong grip to ensure the high-speed driving of the car.

The Hungarian station is another feature, that is, the road is rotten and dirty! Of course, this kind of rotten and dirty are compared to other tracks, and is not the kind of bad road that is usually understood.

The Manicur Raceway is different from Morocco and Hungary. It is still a standard Formula track, just a medium-low speed design. And slow cornering only accounts for 70% of the track, not all.

The wear of ultra-soft tires at low speed is still acceptable. Once it exceeds 200km/h, the wear speed will increase rapidly.

Maybe after only ten laps, the tires were worn seriously, and the high temperature of the tires would cause rubber pelletization, which would further reduce the grip of the racing car.

As for the current length of the Nikur track, the half-hour schedule should be between 22 laps and 23 laps. The specific number of laps depends on the decision of the organizing committee.

But whether it is 22 laps or 23 laps, the grip peak of ultra-soft tires has passed, and even the tires will have a risk of flattening in the last few laps.

In Yamamoto Ukyo's opinion, Zhang Yifei's lap score is already good enough. The mentor wants to replace it with a super soft tire. Does he want to challenge it again in the main competition with this double-edged sword?

Just when Yamamoto Ukyo was full of doubts and confusion, Zhang Yifei's racing car had already entered the maintenance channel.

Listening to the roar of the Renault Racing engine and feeling the car "crashing" towards him at 80km/h, Yamamoto Ukyo was still a little nervous inside.

When Zhang Yifei saw the situation at the repair station, he immediately understood that Kossel did not intend to use the usual tire change method of the previous one, but planned to use the f1 mode to change the tire.

To be honest, Zhang Yifei had only watched this tire change method on TV before, and even though he became a Formula driver, he had never enjoyed this kind of treatment.

He looked at the parking space getting closer and closer, then braked suddenly. Renault race car parked accurately in the parking space, and the distance from Yamamoto Ukyo standing in front could be calculated in centimeters.

Yamamoto Ukyo was very quick to shovel the jack into the front of the racing car, and then raised the entire car by about 50mm. Ah Hu on the side also held a pneumatic wrench and removed the tires as fast as possible. Zhige next to him cooperated tacitly and installed the new tires. The whole process took less than five seconds.

One tire has five seconds, and four tires are about twenty seconds. This is a ten-fold gap for about two seconds for F1 tire replacement.

But you should know that in the official F1 technical team, a tire requires three technicians to cooperate with the tire replacement. Ah Hu and Zhi Ge only have two people, and they have to move and change four more. Five seconds is already a very good speed.

With their current efficiency and speed, there is no big problem with the technician team based on the f3 or f3000 team. It can be said that the progress during this period is not just Zhang Yifei. Faced with the "high pressure" state, Ahu and Zhige's progress is also not slow!

During the tire change process, Zhang Yifei naturally saw the red super soft tire logo on the tire, so he asked, "Cosell, will you use super soft tire next?"

"That's right."

Cosell's answer was still concise and straightforward, without giving Zhang Yifei any explanation.

"But the super soft tire wears very fast, isn't it suitable for Manicur Raceway?"

"You have to run through it before you know if it's suitable. Get ready to set off."
