Chapter 3130: We want to build a sports car

A soldier who does not want to be a general is not a good man, and a car company that does not want to build a sports car is not a really good car company with ideals and aspirations.

At that time, Lamborghini was nothing more than a tractor manufacturer. He felt that Ferrari's clutch was not good enough to give advice, and was despised by others. Later, he decided to build a sports car and finally made a good talk.

Now, the product sequence produced by the Northern Heavy Truck Factory is almost complete, but it is not a sports car. Without a sports car, it cannot be said that it is at the top level of the automobile industry.

Step by step to the present, there is only the last mountain left. Heribala has long been eager to try it. If you want to build a sports car, the most important thing is an engine.

In fact, there is no shortage of high-horsepower engines in the northern heavy-duty truck factory. The ones used by our main battle tanks are 1500-horsepower engines. However, this kind of engine is not suitable for sports cars.

Diesel engines are characterized by their emphasis on torque output and speed-increasing ability. The speed is generally not high. More than two thousand revolutions is the ultimate, while the sports car engine does not pay attention to torque and emphasizes extreme speed. The engine can generally reach tens of thousands of revolutions. , Through this kind of high speed to achieve the improvement of power, at the same time, the engine has to be light.

Therefore, if you want to build a sports car, you must first solve the problem of power. If you use someone else’s engine, what is it called a self-made sports car?

At this stage, the main power of the sports car is still a self-priming engine. However, its own technology has broken through from turbocharging. Therefore, Heriba naturally decided to use this 3.0T engine prepared for high-end models. As the power system of a sports car.

There are two large and small turbines. The small turbine is used to solve the problem of hysteresis, while the large turbine is used to squeeze the power performance of the engine. On the premise of maintaining the stability of the engine, the power of this engine is improved as much as possible.

"Now, under our tuning, this engine has been able to burst out 450 horsepower, the torque has also increased to 550 Nm." Heri Bara said: "However, if this engine is used as a supercar engine. , I still feel weaker."

If it is to build an ordinary sports car, that kind of two-door sports car, the performance of the engine is quite good, the parallel time and space BMW M4, which is the power standard, the Porsche 911, is only 420 horsepower. However, if it is used as the power of a super sports car, it still feels worse.

Real supercars, such as Lamborghini, use a 6.2-liter V-12 engine with a power of 640 horsepower, which can achieve a 100% breakthrough in 3.6 seconds. The Bugatti EB110 uses a V-12 engine that has a power of 553 horsepower in 3.4 seconds. Breaking a hundred, the top speed is 340 kilometers per hour. It can be seen that a real supercar requires an engine with more than 500 horsepower. It won't work to break a hundred in 5 seconds. It takes about three seconds to be called the ultimate.

It is not impossible to continue to improve the power, but if you continue to improve, the reliability will not be guaranteed. If necessary, it can be adjusted to 800 horsepower or 1,000 horsepower, but it will bring a rapid decline in life. The engine of the sports car has become a pain in Heribala's heart. Now this V6 engine, the power has been squeezed to the extreme, after all, the displacement is placed here.

If you continue to increase the displacement, it can be done, but this is equivalent to starting a new stove, and you have to pay a huge investment in research and development. This kind of sports car is only used to install the facade, and it is destined to be impossible to be a product of walking volume, so , This requires a choice.

Faced with the difficulties of Heribala, Qin Guan didn’t have much pressure, and immediately said: “To build our supercar, of course, we must aim at the world’s advanced level. This engine can be used for low-end supercars. For the end model, the high-end supercar model must have more powerful power. I suggest adding two more cylinders on this basis. The V6 structure becomes the V8 structure, and the power can be increased to 600 horsepower. "

Han Guo’s engines are modular. Basically, a cylinder is 0.5 liters. In this way, a 2-liter engine is an in-line 4-cylinder, and a 3-liter engine is a V6. Now, it has a V8 structure. Compared with the existing engine, the change is minimal, and under other constant conditions, it can be easily adjusted to 600 horsepower.

"Our northern heavy truck factory is now a wealthy enterprise. It is completely acceptable to invest a certain amount of money to develop a high-end product for our own beliefs." Qin Guan said, "I have no opinion in this regard. Just do it."

Heribala nodded: "Yes, if we change to a V8 structure, we can get six hundred horsepower."

"On the one hand, we need to increase the power, and on the other hand, we must also reduce the weight of the car body. Our domestic materials have developed rapidly over the years. I suggest that you can even skip aluminum alloy and directly use synthetic materials. Let the weight of the car body be reduced, achieve a higher speed-up index, and strive to run within three seconds."

These super sports cars do not count the cost. Therefore, to reduce the weight of the car body, you can also take the composite materials used in the aircraft. With the blessing of these materials, the weight of the car body can be greatly reduced.

This is also a trend. In that parallel time and space, there was once a sports car enthusiast who just bought a super sports car. As a result, the example of being eaten by his own dog, yes, the dog ate, the dog’s teeth, The composite material can be torn off piece by piece. It is estimated that the most likely breed of this kind of dog is Erha.

Qin Guan’s suggestion is also in line with Heribala’s idea. Since it is said that regardless of the cost, even a new engine can be built, not to mention the car body material.

In fact, if you continue to increase the speed, you can only use the electric motor. The vehicle driven by the internal combustion engine has reached the current level, which is already the extreme, but the electric motor is different. The characteristic of the electric motor is strong torque, fast speed, and electric sports car. , It can even run a hundred kilometers within two seconds, and the absolute ejection start is estimated to be almost the same as that of a carrier-based aircraft.

However, up to now, the trend of electrification has not yet begun. Qin Guan still has a certain prejudice against this electrification. Therefore, he did not propose to conduct research and development of electric vehicles on his side. The true maturity requires a lot of work. These were all in vain in 2017, especially before the breakthrough in lithium-ion battery technology.

"So, what about the shape?" Qin Guan said, "Did you invite internationally renowned designers to do the work?"

There are also shortcomings in this aspect in China. Sports cars must be beautiful and domineering, and they must also comply with aerodynamics. In this regard, China has no reserves.

"We haven't reached that point yet. After all, if we don't have a qualified power system, there will be no qualified sports car." Heribala said.

Qin nodded his head and thought of something: "Nowadays, many sports car brands are in the hardest time to survive. If necessary, you can buy a sports car company. I heard that Porsche has had a difficult time recently. It is time for the heavy-duty truck plant to start expanding abroad."
