Korsell believes in Zhang Yifei's emergency handling ability, except for the first lap because of the tire grip problem, he rushed out of the runway.

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

By the time Zhang Yifei reached lap 30, the fastest lap had reached 1:24.962, almost 0.4 seconds ahead of the Manicul track record. This is definitely an astonishing achievement, and there is no one in history who has ever reached this level of junior Formula 1 driver who has not gone on to F1.

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

It's just that no one can say for sure how long this time is. Especially for a new Chinese driver, it will be more difficult to gain recognition of the strength of the entire European racing circle, and it will have to be more impressive than other drivers.

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

The time of 1:24.962 has reached the standard set by Kossel.

Of course, this is not the standard for F1 drivers as mentioned before, and if you really call a top active F1 driver to drive it, you should be able to lead the current track record by almost one second.

Between 0.4 seconds and 1 second, it doesn't seem like a big difference, but you have to know that the improvement of any track record is more difficult the further you go.

Therefore, the difference in the degree of difficulty is far from being as simple as increasing by half a second, but is increased by geometric multiples.

"Mentor, 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 riders, few people could reach the current crazy improvement of Zhang Yifei.

Judging from the monitoring screen, Zhang Yifei has danced on the sword many times, and any 0.1-second improvement is the possibility of rushing out of the track.

Even if theoretically there will be no major safety incidents, who can be sure of some things? If there is a height difference that causes the car to tumble, the consequences are unimaginable.

The reason why Senna died that year was that a piece of metal flew out of the suspension and pierced his helmet directly.

At high speeds, a small fragment can be as deadly as a bullet, and no one can really pack a ticket to ensure safety.

"Hmm."

After hearing this, Kossel nodded slightly, and indeed Zhang Yifei's performance and hard work on the track were recognized by Kossel.

Even if he uses the standards of F1 drivers to demand, Zhang Yifei uses his best efforts to achieve his goals. As far as this result is concerned, as long as there are no major mistakes in the official races, it is guaranteed to get pole position and break the track record.

Even if other drivers also broke the track record, Korsell didn't believe they were as fast as they were!

This is not to say that Korsell is biased towards his own people, on the contrary, he has higher requirements for Zhang Yifei, but strict is severe, Korsell never thinks that Zhang Yifei is weaker than other drivers, the difference of 0.4 seconds, is the performance of the strongest Renault driver in this session and the city!

Many times, Korsell didn't want Zhang Yifei to challenge other drivers, what he wanted to challenge was actually himself!

"Fly, get back to the pits, and get ready for a tire change."

At this time, Korsell used the team's intercom system to issue a command to pit and change tires.

Now Zhang Yifei has run 30 laps, although the length of the Manikul track is almost three kilometers shorter than that of Monza and Hockenheim that he ran before.

However, the total length of the 30 laps was still close to 130 kilograms, and the grip of the soft tyres had passed its peak by this time. In order to be faster and safer in cornering, it is necessary to pit and change tires.

It's just that the next command issued by Cer made Yamamoto Ukyo a little incomprehensible, he did not change to the regular soft tires he used before, but to the super soft tires with stronger grip!

"Ukyo, you're in charge of the front jack."

In Formula 1, there is no detailed division of labor among the mechanic teams, but in the F1 technician team, the technicians in charge of the front and rear jacks are called "Jack Holders", which means jack holders.

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

If the driver can't accurately control his speed and stop accurately, then the speed of 80km/h in the pit lane is enough to knock the "jack bracket" standing at the front of the car into the air, and this kind of accident has also happened in the history of F1.

Especially for a rookie like Zhang Yifei, who has not yet been exposed to F1 car pit stop training, the danger is even greater, purely depending on Zhang Yifei's buckle for the braking distance of the car.

Korcel gave this most dangerous position to Ukyo Yamamoto, which was a sign of trust in his students.

Similarly, Yamamoto Youkyo did not hesitate, picked up the jack and waited in front of the maintenance parking space, which was also his trust in Zhang Yifei's driving skills.

While waiting, Yamamoto Ukyo still couldn't help but ask: "Mentor, are you really sure to change to super soft tires?" ”

"That's right, it's super soft tires, there is not much time left to rent the track, and if there are not enough people, move faster."

Cowel urged, not caring about the tires.

You must know that the official F1 pit stop tire change, with a team of up to 17 technicians, each tire is three technicians working together, in order to change four tires in just 2 seconds for the driver to leave the pit stop to continue the race.

And now Zhang Yifei's team, plus Yamamoto Ukyo, a data analyst who should have been in the strategy group, is only three people, and the number is not an order of magnitude at all.

While the test run wasn't like a race against the clock, there was still a limit to how long the track could be rented, and there wasn't much time left, and Kossel wanted to test how much the supersoft tyres wore out on the Manicul track.

Hearing the words of the mentor, Yamamoto Ukyo's doubts can only be pressed in the bottom of his heart, the frequency of use of super-soft tires in the current formula racing is actually not very large, because limited by the development of rubber technology, super-soft tires are too wear-resistant.

It is only on some slow and curved tracks that require extremely strong grip support that the ultra-soft tyre type is used. For example, the Moroccan station in the F1 Grand Prix, the Hungarian station and so on.

Each of these tracks has its own distinctive characteristics, and the Moroccan race is due to the fact that the existing streets, narrow and bends, are not fast, and require extremely strong grip to ensure that the cars can travel at high speeds.

Hungary station is another feature, that is, the road is rotten and dirty! Of course, this kind of rot and dirt is relative to other tracks, not the kind of rotten road in the usual understanding.

Unlike Morocco and Hungary, the Manikul circuit is still a standard formula circuit, designed for low and medium speeds. And the slow corners only occupy 70% of the track, not all.

The wear of the ultra-soft tyres at low speeds is acceptable, and once it exceeds 200 km/h, the wear rate increases rapidly.

It may only take a dozen laps before the tires are already worn out, and the high temperature of the tires will cause the rubber to granulate, which will further reduce the grip of the car.

As far as the length of the current Nikur circuit is concerned, the half-hour course should end with 22 to 23 laps, and the specific number of laps depends on the decision of the organizing committee.

But both laps 22 and 23 were past the peak grip of the super-soft tyres, and even the tyres were at risk of smoothing out in the last few laps.

In Yamamoto Ukyo's view, Zhang Yifei's lap time is good enough, and the mentor wants to change to super soft tires, does he want to challenge again in the main race with this double-edged sword?

Just when Yamamoto Youkyo was full of questions and puzzles in his heart, Zhang Yifei's car had already entered the maintenance channel.

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

Zhang Yifei saw the posture of the pit station, and instantly understood that Korsell did not plan to use the previous ordinary tire change method, but planned to use the F1 mode to change the tire.

To be honest, Zhang Yifei had only seen this kind of tire change on TV before, and even if he became a formula driver, he had never enjoyed this kind of treatment.

He looked at the parking space that was getting closer and closer, and then braked sharply, and the Renault car stopped precisely in the parking space, and the distance from Yamamoto Ukyo, who was standing in front, the distance could be calculated in centimeters.

Yamamoto Ukyo moved quickly, shoveling the jack directly into the front of the car, and then raising the whole car by about 50mm. Ah Hu on the side also held a pneumatic wrench to remove the tires as quickly as possible, and Brother Zhi next to him tacitly cooperated to install the new tires, and the whole process took less than five seconds.

Five seconds for one tyre, almost twenty seconds for four tyres, which is a tenfold difference of about two seconds for F1 to change tires.

But you must know that in the official F1 technical team, one tire needs three technicians to change the tire, Ah Hu and Brother Zhi only have two people, and they have to keep moving to change four, and five seconds is already a very good speed.

With their current efficiency and speed, there is not much problem with the team of technicians based on the F3 or F3000 team. It can be said that the progress of this period of time is not just Zhang Yifei alone. In the face of the "high-pressure" state, Ah Hu and Brother Zhi's progress is also not slow!

In the process of changing tires, Zhang Yifei naturally saw the red super-soft tire logo on the tire, so he asked: "Kossell, will you use super-soft tires next?" ”

"That's right."

Cosell's answer was still succinct and crisp, without giving Zhang Yifei any explanation.

"But the supersoft tyres wear out very quickly, so the Manikul circuit doesn't fit it, right?"

"You don't know if it's suitable to run through, so let's get ready to go."

It's still the same old saying, you can't die if you rush off the track, anyway, try it first.
