Niu Xiaoqiang couldn't help but look at Packard and exclaimed: "Mr. Packard, you are really amazing, you can actually make a dual V8 architecture engine!"

Packard smiled quite proudly: "The dual V8 architecture is the name of the layman, I call this kind of engine the V16 engine, boy, since you know how good I am, you'd better pay attention when you speak, don't talk nonsense." ”

Niu Xiaoqiang shook his head: "I can't say that, although I agree with your ultra-high technology in the engine field, but for the field of modified cars, I still don't quite recognize it." ”

Packard snorted: "Then tell me, what am I not doing well enough?"

Niu Xiaoqiang's words are back to the point: " As far as I know, when the speed reaches 80 km/h, about 60% of the power of this car will be used to overcome wind resistance, that is to say, it can only exert 40% of the engine's ability, which is still compared to those vehicles with a streamlined appearance, if it is this Pontiac GTO, the kinetic energy it consumes to fight wind resistance will be more amazing, so you have to try to increase the power of the engine, if you don'tI'm afraid that this car can't go to the track to compete with other cars. ”

Packard glanced at Linda: "The appearance of the car is a matter of personal preference, if you only pursue speed, why not buy a Ferrari for modification, and spend so much effort to modify this Pontiac?"

Linda agreed: "Yes, if I didn't like Pontiac very much, I wouldn't have spent so much effort modifying it, and if it were to change to other models, I wouldn't even bother to change it." ”

Of course, Niu Xiaoqiang understands this truth, and he didn't think of forcibly changing Linda's personal preferences, the reason why he made such a big deal about the appearance of the vehicle and the drag coefficient was mainly to pave the way for the next topic.

Seeing that the heat was almost up, Niu Xiaoqiang immediately said his true thoughts: "If Auntie is really unwilling to change the appearance of the vehicle to reduce wind resistance, then she can only work hard from another place." ”

Linda was curious, "What place?"

Niu Xiaoqiang reached out and knocked on the hood of the car, making a dull echo, he shook his head with a smile: "Don't you two think that the shell of this car is too heavy? If the shell is rebuilt with lightweight materials, this car will still maintain its super tough style, but the weight of the body will be greatly reduced, which means that the engine can use less power to offset the heavy body load, so as to use more power for Mercedes-Benz." ”

In the same way, the lighter the load, the faster the car will run, and this truth is clear even to people who don't know how to drive. Linda and Packard, as veterans, certainly understand better.

It wasn't that the two didn't think about reducing the weight of the body, but after much consideration, they finally had to cancel the idea.

There are two main reasons, the first is that lightweight raw materials are not so easy to find.

Packard's engine modification skills were very good, but he did not study materials science and did not have the ability to invent lightweight materials.

Of course, this problem does not require mastery of materials science, let alone the invention of new materials, and can be solved in other ways. This is done by reducing the thickness of the body shell.

In this regard, Japanese car companies have done a very good job of reducing the thickness of the body shell to an outrageous level, and it is no exaggeration to say that a grown man can dent the body of a Japanese car with a single push of his finger.

If you're using a family car, this is a very cost-effective option to save fuel and increase speed. But racing cars can't be seen in terms of the requirements of family cars, the speed of the cars is too fast, and in the event of an accident, the impact is far stronger than that of a family car.

Especially for someone like Linda, who loves off-road rallying, it's more dangerous than on the track, so safety is an issue that all racers must take seriously.

There is no one who does not value their lives, racing is a very dangerous thing, if you don't pay attention to safety, maybe this race will be the last race of your life.

Take the world's most advanced F1 race, for example, where drivers die on the track every year. One is because F1 is too fast, and the other is because they sacrifice the protective performance of the car in pursuit of speed.

As we all know, F1 cars have reduced everything that can be reduced, and they have tried to reduce the parts that cannot be reduced. How do you take safety into account? Someone once joked that an F1 driver is actually racing on an engine, which may seem like an exaggeration, but it's not unreasonable.

With so many bloody lessons in front of her, Linda had to carefully consider the consequences of reducing the thickness of the body shell. After much consideration, she finally chose to improve the performance of the engine and retain the original thickness of the body shell, at least to improve the safety factor.

Packard pouted when he heard this: "It's easy to say, how can it be so easy to find materials that are both safe and lightweight? Take F1 cars as an example, they are still using aluminum, and this Pontiac is also using aluminum bodies, so many car manufacturers, if there are suitable new materials, people have already used them, how can they still use aluminum materials today?"

Niu Xiaoqiang smiled slightly: "If others don't have it, it doesn't mean that I don't." ”

Packard couldn't help but be stunned, and then hesitated: "You have? By the way, what the hell do you do? Why are you so familiar with cars?"

Linda explains: "Don't underestimate him, he's a student but he owns a small car factory. ”

Packard was shocked, "What do you say? He, he has a car factory under his name?!"

Linda nodded firmly: "You heard it right, he does have a car factory under his name." ”

Packard looked at Niu Xiaoqiang again with a scrutinizing gaze, and then sighed: "I really can't see that you kid is so powerful, if Linda hadn't told me, I wouldn't have believed it anyway." ”

Linda is more concerned about lightweight materials, as it will help her to do well in the coming year's events. I saw her ask: "Xiaoqiang, what do you mean by the light material you just said?"
