"Is the gap really that big?" Qiao Yu was shocked when he heard this.

Ling Feng nodded: "According to my understanding of Mengmeng's car skills, this is indeed the case. Don't look at our group of young people in Zhushanzi all play motorcycles, but a few of us can't reach this level, and the only one I think can be compared with Zhou Chun is still nursing children in his hometown. Forget it, just like Meng Meng said, there's no shame in losing to the former national champion!"

After listening to Ling Feng's words, Qiao Yu complained to Chen Jiao and said, "Look! It's the trouble you're looking for!"

Chen Jiao said with a bitter face: "I didn't know it would be like this! By the way, Ling Feng, what did you just say, what is the difference between the two cornering techniques of 'inverted sidehang' and 'inward inclination'?"

Ling Feng lit a cigarette and took a puff before explaining to Chen Jiao: "The cornering technology of motorcycles is actually improving: it turns out that most riders use the cornering technique of 'internal side hanging', which is to move the center with the waist as the center, and the knees are open close to the ground to exert the effect of the center of gravity to move quickly to achieve the purpose of fast cornering." When Zhou Chun was cornering just now, his knees rubbed against the ground to produce sparks, because he used this cornering technique. ”

"With the evolution of the electronic control system of motorcycles and the obvious improvement of tire performance, most of the cornering techniques adopted by professional riders in the last ten years are called 'inversion', which does not move the waist, but leans on the rider's upper body and head to the inside of the corner, so that the turning angle can also become deeper and faster. One of the drivers used this technique, and even tilted the body inward by nearly 69 degrees, and the whole car felt as if it was lying on the ground. ”

Qiao Yu complained: "It's just Dongying talent to challenge such a strange record." ”

Ling Feng shook his head and said: "To be precise, this kind of cornering posture is really created by Dongying people, but it is not Dongying's professional drivers, but Dongying's police." ”

"Police?" Quan Yajing asked puzzledly, "Do you want the police to be a professional motorcyclist?"

Ling Feng shook his head and said, "It's just an ordinary Dongying policeman." Because the Toei police all ride white motorcycles, this cornering position is also called 'white motorcycle pose'. Sports meetings are often held between the police officers to compare various police skills, and according to the rules of the motorcycle time trial, the motorcycle, including any part of the rider, cannot touch the ground. The original intention of formulating this rule was to allow those police officers to complete their tasks safely no matter what situation they encountered, and the motorcycles equipped by the Dongying police are equipped with ordinary tires and the body is large and heavy, no matter what kind of road conditions such as rain or snow, they must be dispatched by motorcycle. For safety reasons, they also don't use the 'inside side-hanging' method to get around corners, so over time this 'inward' cornering technique was invented."

After hearing this, Chen Jiao said: "But just now I saw that Zhou Chun's inversion angle was not large, why do you say that he chose the best technique?"

Ling Feng said with a wry smile: "This problem is multifaceted, in fact, it is not right to blindly pursue the tilt angle, the tilt angle is too large, but the speed of the car will be slowed down, and the tire grip will also become weaker at that time: after all, the contact surface between the tire and the ground has become smaller." So the right thing to do is to make the angle of inclination of the car as small as possible, the driver hangs on the side of the car when cornering in order to shift the center of gravity, if it is possible to turn when people are outside the car and the car does not tilt is the best way to corner, of course, considering the centrifugal force inertia and other problems, this is also impossible. The faster you go through corners, the greater the angle of inclination of the bike. In races like the MOTOGP, the riders lean more than 65 degrees when cornering with the inward lean technique! That's because the speed of the car is too fast, centrifugal force and inertia, and if you don't use this angle, the car will fly out. It's the same as the Dongying police use this position to ride a bicycle, or for safety. ”

When the tire is upright, the contact area between the tire and the ground is the largest, and the grip is the strongest, and the grip is the smallest when cornering, and the tilt angle of the body is pressed to the sidewall, which is also the way to increase the contact area between the tire and the ground to strengthen the tire grip. It is impossible for ordinary tires to have the perverted grip of track hot melt tires, although the two of them are now using semi-hot melt tires with good grip, but compared with those track tires, the gap is huge, plus now they are running on ordinary roads and not on the track, and now Zhou Chun's cornering choice is really textbook-level. ”

After listening to Ling Feng's words, everyone didn't believe that Yang Meng could win. After all, Ling Feng is Yang Meng's friend, and he has a very good relationship with Yang Meng, and he knows Yang Meng very well, so he said so. It seems that Yang Meng's chances of winning are infinitely close to zero.

Quan Yajing looked in the direction where Yang Meng ran out: "Mengmeng, is this going to give up?"

Everyone turned their heads to look at the past, hey, Yang Meng was leisurely, running slowly on the S-shaped route on the road.

Ling Feng frowned: "He didn't give up, but seemed to be going to move seriously, which is rubbing the tires to increase the temperature of the tires." How can I have a sense of foreboding?"

"Ominous premonition?" Qiao Yu asked puzzled, "What do you mean?"

Ling Feng blinked: "The best thing may be that you need to change the tires." ”

"What about the worst possible scenario?" Qiao Yu asked puzzled.

Ling Feng didn't speak, but his eyes were full of nervousness.

And at this moment, a roar was heard, and the red HP4 that Yang Meng was riding directly and quickly accelerated, and rushed directly towards that corner.

Ling Feng was originally sitting on Harley 833 smoking, but when he saw this scene, he jumped up directly, looking at Yang Meng's car shadow with a frightened face, the cigarette butt burned his hand, he threw the cigarette butt out of his hand, and when he raised his head, Yang Meng's car shadow was gone.

Ling Feng hurriedly turned around and asked the people around him, "Where is Mengmeng?"

"Ahh

Ling Feng said in surprise: "He didn't crash?"

"Huh?" Quan Yajing was also stunned when she heard this question: "Isn't Mengmeng your good friend?

Ling Feng's eyes widened: "This is impossible。。。。。。 It's simply impossible!"

Quan Yajing was puzzled and asked, "What is impossible?"

Ling Feng took the index finger of his right hand in his mouth and dipped it in saliva, then stretched it out in front of him: "The current wind direction and wind speed 。。。。。。 He was at least 12 hours away from that bend!"

"One hundred and two, that's fast!" Chen Jiao said.

Ling Feng covered his face: "Are you playing with cars?

The women glanced at each other, but Qiao Yu spoke: "I will bend some ordinary corners 70 times." ”

Ling Feng pointed to the S bend just now: "That's an ordinary bend?"

Chen Jiao said: "I have seen a movie played by Andy Lau and Gigi Leung, in which Gigi Leung said that Andy Lau dares to turn at a speed of 200 per hour! That is the ultimate goal of our efforts!"

Ling Feng was completely speechless: "Eldest sister, that's a movie! You believe in movies, and you can do it! I'll just say this, you let the top drivers of MOTOGP not dare to turn two hundred!"

"Huh?" Chen Jiao froze in place.

Ling Feng explained: "Forget it, let me explain it to you, first ask a cliché question: is it the speed of the motorcycle or the speed of the car?"

"Motorcycles, of course!" replied the three girls in unison.

Ling Feng smiled bitterly: "Eldest sister, you are comparing your car with an ordinary car. In the case of the same level of racing, for example, if you compare F1 and MOTOGP, or compare the upgraded motorcycle with the supercar, in terms of acceleration and top speed, the motorcycle does have a chance to win, but in terms of braking and cornering, the motorcycle is not the opponent of the four-wheeled vehicle of the same class at all. ”

"Won't it?" Qiao Yu was a little stunned after hearing this: "I can also win a four-wheeled car with this driving skill!"

Ling Feng sighed and said: "What kind of car are you comparing to? Just like this Audi, this is a sports car, right? But compared to your car, it is not a level! Your HP4 belongs to the public upgrade sports car, which is the highest level of motorcycle sports cars, so it should also be compared with a supercar like Bugatti." I'll give you an example, every year Austin Circuit hosts both F1 and MotoGP races, where the fastest lap time in F1 is 1 minute and 40 seconds, and the fastest lap time in Motogp is 2 minutes and 4 seconds. ”

Qiao Yu was puzzled and asked, "Why is the gap so big?"

Ling Feng said: "There are too many factors involved here, for example, when cornering, the car has four tires, and the grip is definitely much higher than that of a motorcycle, so you can go down the corner at a faster speed, and what is the most important thing in F1? Especially in the relatively small difficulty of the high-speed corner, such as the Austin circuit at Turn 19, the fastest F1 car is 169 kilometers per hour, the same corner, the fastest turning speed of the motorcycle is only 115 kilometers, the speed difference is more than 50 kilometers per hour! So it's not surprising that there is such a big time difference in running a lap on the track. ”

Only then did Qiao Yu react to the problem: "Just now you said that Yang Meng took at least one hundred and two corners, how did he do it?"

Ling Feng spread out his hands: "Who do I ask if you ask me? The aerodynamics of motorcycles are weaker than those of cars! Even if MOTOGP's cars use front spoiler fins now, there is still no conclusion on how much they are used! Can he keep the car stable when cornering at that speed? How much downforce does it take? And if the downforce is too high, your car tires may not be able to stand it! I can't figure this out now, it seems that my nickname is going to be given to him. ”

"What is your nickname?" asked Quan Yajing curiously.

Ling Feng replied lightly: "Crazy!"
