Zhang Yifei has no objection to Prost's arrangement. Although he is very confident to challenge the rainy track, many things can overcome everything without confidence, and sufficient preparation is the basis for overcoming everything.

Zhang Yifei, Cowel and Alesi race engineer Cord all stood in front of the circular screen in the P room, listening to the track feedback from Alessi.

Today's rain is considered a torrential rain at the beginning according to the weather forecast standard, but by the time of the official practice session, it is almost moderate rain.

F1 races are not held at any rain level, and if there is really an exaggerated rainstorm and the rain exceeds the displacement of the rainstorm tyres, in order to ensure the safety of the drivers, F1 officials will also choose to stop or end the race early.

Therefore, the upper limit of F1's tolerance for rain battles is what heavy rain looks like.

However, as the safety of drivers became more and more stringent, the standard of rainy racing was repeatedly lowered, and the rain battles that could be seen were even lowered from heavy rain to moderate rain.

Because in the official race, there is not only the risk of side skidding, but also the mist splashed by the car in front during the journey. In addition, at high speeds, the car in front can drive an exaggerated effect like an air hood, and the visibility of the car following behind is extremely low, making it feel like driving in a large fog.

Except for the red warning light that lights up at the rear of the front car, if you get a little closer, the rear car can't even see the outline of the car in front clearly.

Think about foggy weather, the traffic regulations in foggy days, in the case of visibility less than 50 meters, the speed of the vehicle must not exceed 20 kilometers per hour.

For an F1 car, if you drive at 20 km/h, are you messing with me? At the very least, you'll have to multiply the speed tenfold to be worthy of the title of the fastest race on the planet.

Especially in the initial stage, the mist brought up by the wheels made it impossible to even capture how many cars there were on the broadcast camera. Coupled with speeds of more than 200 km/h, this handling ability has surpassed the limits of human beings, and even F1 drivers cannot avoid car collisions.

So the rain battle, in a sense, is the most intense and exciting event in F1. It's just a pity that this kind of wonderful scene is rarely seen in later generations, after all, all the wonderful pictures are drivers swimming on the edge of loss of control with their lives.

"How are Bridgestone tires performing?"

Cod asked Alesi that the most important thing about a Formula 1 car on a rainy day is the grip and drainage of the tires.

After 2007, F1 implemented an exclusive agreement with a tyre supplier, with all teams using tyres from the same brand.

But at this stage, there are two tire suppliers in the F1 paddock, namely Bridgestone, a "newcomer" who entered F1 in 1997, and Michelin, a veteran tire supplier.

Bridgestone is a tire brand from Japan, before entering the F1 supplier in the 90s, Bridgestone and big brother Dunlop, Goodyear and Michelin are still relatively far behind, especially in Europe, the largest tire market at that time, completely uncompetitive.

But with a bid price of more than $25 million a year, Bridges won the spot as a supplier of Formula 1 tires.

It can be said that bidding for an F1 tire supplier was the wisest choice for Bridgestone in the 90s, and its European brand awareness rose from 13% to 34% in the past few years as a tire supplier!

The increase in popularity naturally led to an increase in sales, which made Bridgestone the world's largest tire manufacturer.

However, at this stage, Bridgestone's trust is still not as good as the old Michelin, so Cod first asked Alesi how the performance of Bridgestone's wet tires is.

"It drains well and has a good grip."

Alessi's feedback voice came, and everyone in the pit station nodded subconsciously, Bridgestone tires could still withstand the test of rainy weather.

After all, this year, Bridgestone has not only supplied the Prost team, but also supplied McLaren and Ferrari, two top teams, and has won many constructors' championships.

After verifying the drain performance of the Bridgestone rain tyres, the pit ring screen began to show that Alessi was increasing his speed.

Looking at the beating of the numbers on the screen, this feeling made Zhang Yifei feel amazing. You know, he's always been the same driver on the track, and it's rare to have a chance to stay in the pits and look at the race stats of other drivers, and today is the first time in a sense.

"The tires are a bit slippery in high-speed cornering, and the grip is not enough, so you need to adjust the angle of the front and rear fixed wings to the maximum."

The aerodynamic wing on a F1 car is the most important part of the aerodynamic package, responsible for adjusting the downforce and resistance of the car.

The fixed wind wing is a scientific name, in more popular terms, it is the exaggerated tail wing that you see many cars at the rear of on the road, and it is modified. To put it in an official way, this large rear wing can be called a rear fixed wind wing.

The downforce generated by the fixed wing is directly proportional to the drag, and the smaller the angle of opening, the less downforce is generated, and the less drag the car is advancing.

If the drag is reduced, then the acceleration and top speed of the car will naturally increase. However, the side effect is that the car lacks downforce, resulting in a lack of stability, especially in high-speed cornering situations, and it is easy to rush off the track with insufficient grip.

On the contrary, the greater the angle of the fixed wing, the greater the downforce of the car, so that it can use fast speed to corner, but in terms of acceleration and straight speed, the speed is much slower.

At the same time, the increased downforce will also cause tire wear to become more severe, which will increase the number of pit stops.

Therefore, all the tuning in F1 is a science, and the matching of the car gears, the angle of the fixed air wing, the choice of tires, etc., all require precise calculations and track feedback to get the best results.

"The rain is cooling down the car, so consider using smaller brake vents and engine cooling vents."

Alesi's feedback from another track came, and the suggestions given this time were more professional, and even Zhang Yifei had not thought of changes.

You must know that when the angle of the fixed wind wing is maximized, the resistance faced by the car will be the greatest, and the factor of rain will inevitably affect the speed of the car.

The small size of the brake and engine cooling ducts not only prevents rainwater from entering these ducts, but also reduces air resistance. The average rookie driver would not think of changing the internal parts of the car, and Alessi's experience as a veteran highlights it.

"It's all written down, you're ready to pit stop."

Korser replied to Alesi that he had already run a few laps of technical laps and needed to pit for the next stage of the timing lap to be adjusted.

After saying this, Korsell turned his head and issued instructions to the team's team of technicians, asking them to follow Alesi's track feedback as fast as possible to help Zhang Yifei's car adjust and change.

At the same time, Cosell also looked at Zhang Yifei and said, "Fly, prepare the technical testing circle." ”

“OK。”

Zhang Yifei nodded in response, he pulled on his racing jacket, then put on a mask and helmet, and walked in the direction of the car.

In an instant, a sultry sensation hit Zhang Yifei, and the hot and humid weather in Malaysia is really not very friendly to F1 drivers wearing heavy racing suits.

This kind of small tuning is simply a small meaning for the professional mechanics of the F1 team. Just when Zhang Yifei was wearing these racing equipment, the tuning had been completed, waiting for Zhang Yifei to drive onto the track.

Sitting in the racing car, inserting an ignition device into the tail to start the car, just when Zhang Yifei was about to push the mask down, Ah Hu in the parking space hurried over and instructed Zhang Yifei: "Brother Fei, be careful in the rain." ”

Looking at Ah Hu's slightly nervous appearance, Zhang Yifei smiled at him, and then said, "Don't worry, isn't your Fei Ge's ability unclear?" If it had been placed twenty years ago, there would have been no Senna in the rain, and only Zhang Yifei in the rain would have been left! “

Seeing Zhang Yifei at this moment, he was still in the mood to brag, and Ah Hu's inner tension was also eased a lot.

"Snap" closed the helmet mask, then the gear released the foot throttle down, the engine speed began to increase instantly, and the car quickly drove away from the pit and entered the pit lane.

The team members were not idle at the moment, and quickly rushed to the maintenance parking space outside the P room, because at the entrance of the pit lane at this moment, Alessi's car had already driven in, and he was preparing to pit stop for adjustment.

As soon as he entered the maintenance channel, Zhang Yifei instantly felt that it was different from the previous driving, and the most direct point was that the rain dripped on the helmet, forming a series of water marks.

Even if the helmet has been sprayed with water repellent in advance, there is still no way to completely avoid the traces of water droplets. These raindrops, which kept falling, greatly affected the driver's vision and concentration, and Zhang Yifei had to overcome this interference.

The problem is that the water droplets outside the helmet are protected by water repellent, and the fog inside the helmet is really difficult to solve due to the difference between humidity and temperature. This feeling, like driving after rain in winter or summer, fogging the glass inside the window, is a factor that seriously affects the line of sight.

The inner glass of the F1 helmet actually has a lot of special plating to prevent fogging. In addition, the fireproof hood of the racing car can also play the role of a mask to a certain extent to avoid fogging inside the helmet.

But even with all kinds of measures, like a falling raindrop, there is no way to completely solve it. This also needs Zhang Yifei to overcome quickly.

Of course, this is not the first time that fogging has happened, there have been a lot of winter tests, and Zhang Yifei has been used to it. It's just that it is interfered with the raindrop water marks, Zhang Yifei is the first time, and it takes a little time to get used to.

Therefore, after leaving the maintenance channel, Zhang Yifei's speed did not drive very fast, and the technical inspection circle was even slower than the previous Australian station.

But not long after he drove onto the track, a racing car whizzed past him, and the splashing mist was overwhelming, and in an instant, Zhang Yifei saw a white expanse in front of him.

It's like a puddle on the side of the road when it's raining, and you're walking unhurriedly, and a car is driving by at high speed, and the water droplets from the tires splash you directly into a soup chicken.

Although Zhang Yifei knew that this kind of thing could not be avoided, was it necessary for the practice session technical test lap to overtake so closely?

Just when Zhang Yifei was greeting all kinds of greetings in his heart, the mist fell, and he saw that the "forgive green" color scheme of the car in front of him was not the car of the Minardi team?
