In a state of selflessness, Li Fanyu's three weeks passed in a hurry. Pen % fun % Pavilion www.biquge.info

Gathering the strength of the entire Zhengxin, all the components on the modification plan have been preliminarily trial-produced and have undergone feasibility tests.

After personally working with the engineer to get a nut on the left side, Li Fanyu got up and wiped the oil on his face.

At this time, in front of him. There has been a car that looks like an A4, but is already a completely different guy.

In order to cater to the Chinese market, Li Fanyu exchanged not the original A4 in the previous time and space, but the wheelbase enhanced version of the A4L. L stands for long, which means lengthened.

Increasing the wheelbase will naturally increase the space in the car, but it will not benefit the handling. The most intuitive embodiment is that the wheelbase is elongated from the rear, and the turning radius of the vehicle becomes larger. That is, the longer the wheelbase, the greater the steering angle required for the steering lock. This is fine at low speeds, but at high speeds, the impact on handling performance is still significant.

Therefore, in Li Fanyu's modification plan, the wheelbase was directly shortened in an effort to obtain greater handling.

BUT THE PROBLEM ALSO ARISES, THAT IS, AFTER THE WHEELBASE IS SHORTENED BY 35MM, THE PROPORTION OF THE B-PILLAR IS NOT RIGHT. When the B-pillar is moved back, the distance left for the rear door is too short. So he simply didn't do anything and canceled the back seat of the car and changed it to a two-door version.

In terms of appearance, in order to enhance the stability of the car, he widened the body and lowered the height of the vehicle. On top of this, an aerodynamic package was added to achieve better drag coefficient and high-speed performance.

After repeated wind tunnel tests, it was found that the tail of the A4 had slight turbulence after the addition of an aerodynamic package. TURBULENCE AT SPEEDS ABOVE 220 KM/H CREATES A VACUUM ZONE THAT IS NOT LARGE, BUT SLOWS DOWN THE VEHICLE.

In order to solve this problem, the rear of the car was modified by Li Fanyu, similar to the fastback shape of the previous Porsche Paramela.

After making all kinds of changes, the whole car is given a rather streamlined style.

This is the exterior part.

The body part uses the lightweight aluminum body used by the A8 at the time, and combines it with the carbon fiber integrated cockpit customized in the United States. The ultra-light and high-strength body has been further reduced in weight but with a large increase in strength.

The renovation of the interior part is the most tortuous in the whole plan.

The first engine used was based on the V63.0L engine modified by Wang Rui, and an off-time ignition system was added. Combined with the electronic control unit developed by the previous three Xueba, but has not yet been put into use, it was transformed into a V63.0T electronic turbocharged engine.

Although the main body of the engine still follows the modified version of Wang Rui, because of the special performance of the electronic turbine, the compression ratio of oil and gas in the cylinder is further enhanced, and the acceleration lag caused by the working mode of the turbine blades driven by energy in the traditional turbine engine is solved.

In fact, the solution is very simple: the turbine is controlled by an electronic control unit, so that even when the accelerator is not pressed, such as when decelerating or turning, the electronic control unit will force the fuel supply system to inject a large amount of gasoline into the engine cylinder, but it will not ignite.

Instead, this atomized gasoline is directly passed through the engine into the extremely hot exhaust system without combustion. When the atomized gasoline enters, it will automatically detonate in a high-temperature environment, and the generated pressure will rush to the turbine intake duct, pushing the booster gas blades to continue to accelerate.

In this way, the turbine blades can maintain a rotation rate of about 14,000-20,000 rpm, even when the car is slowing down. While greatly improving the performance of the engine itself, it also solves the root cause of turbo lag.

After this explosion, the V6 engine that had already undergone the expansion and explosion reform was completely changed again, and when tested, the engine that was already a metamorphosis could output nearly 320KW power, more than 400 horsepower, and more than 500 NM of torque.

But after Li Fanyu saw the test results, he was deeply disappointed.

It's just weak!

Because the task given by the system is to improve the performance as much as possible, even after this magic change, he still feels that it is not enough.

And so an even crazier, more inhuman engine came into being – the electro-turbocharged W12!

After Wang Rui's magic modification routine for the V6 engine was applied to the W12 mounted on the A8, Li Fanyu installed the electronic turbine after four days of continuous fighting. After the magic change was completed and the test was carried out, there was a set of data that made all the R&D teams flash their jaws;

650kw！

855 hp!

THE MAXIMUM TORQUE IS NEARLY 800NM!

In order to match such a terrifying heart, the R&D team enhanced the material of the 7-speed dual-clutch gearbox, and paid a high price from Dunlop to customize ten sets of large wheels and tires used in straight-line acceleration racing cars.

And in order to make this rampant world-destroying guy stop and slow down in the fastest time, the R&D team is really embarrassed - Zhengxin can't do it with the existing braking system......

In the end, it was the Tsinghua team that contributed to their ongoing project, PAN carbon fiber materials.

The material is made by subjecting the fibers to high temperature treatment to oxidize them, and then carbonizing the fibers. The carbonized fibers are then roasted at high temperatures for a long time, and during the baking process, carbon-rich gases are added to cause a chemical reaction. The fibers are perfectly blended with carbon oxides to form ultra-high hardness, ultra-high wear resistance, and ultra-high temperature resistant plates.

With this kind of plate, it is not enough.

According to the performance of this plate, Li Fanyu threw out the front and rear double sets, double brake cylinders and strong cooling airflow brake caliper system of the previous space-time F1.

During the simulation test, the entire braking system showed a high level of performance. Judging from the data, 300KM/h-0KM/h, this system can control this process within 4 seconds.

Because during the test, each brake will make the fiber brake pads turn a bright red and make a screeching sound, the R&D team directly named this set of brakes Hot Wheels.

That's right, with a children's sound......

In addition, it is connected to the electronic control system, which can control the body attitude and suspension height according to the speed of the vehicle, enhance the grip and the four-wheel drive force can change with the body posture, thereby enhancing the cornering performance, and the NOS nitrogen combustion system installed in the rear row by Li Fanyu in order to make up for the imbalance in the front and rear weight ratio of the body caused by the reduction of the weight of the rear seats.

Now, what is displayed in front of Li Fanyu is already a complete track monster!
