In a state of selflessness, Li Fanyu's three weeks passed in a hurry.

Gathering the power of Zhengxin, all components of the modification plan have been initially trial-produced and have passed feasibility testing.

After working with the engineer on a nut, Li Fanyu stood up and wiped the oil on his face.

At this time, in front of him. A car that looks like an A4 but is completely different has appeared.

In order to cater to the Chinese market, what Li Fanyu exchanged from space was not the original A4 from the previous time and space, but the A4L with an enhanced wheelbase. L stands for long, which means lengthening.

Enhancing the wheelbase will naturally increase the space inside the car, but it will not be good for handling. The most intuitive manifestation is that the wheelbase is lengthened from the rear, and the turning radius of the vehicle becomes larger. In other words, the longer the wheelbase, the greater the steering angle required for the steering lock. This is okay at low speeds, but at high speeds, it still has a great impact on handling performance.

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

But a problem also arises, that is, after the wheelbase is shortened by 35MM, the proportion of the B-pillar is wrong. After moving the B-pillar backward, the distance left for the rear door is too short. So he simply didn't stop doing anything and canceled the rear row of the car and changed it into a two-door version.

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

After repeated wind tunnel testing, it was found that the rear of the A4 had slight turbulence after the aerodynamic kit was installed. When the vehicle speed exceeds 220KM, turbulence will create a vacuum zone that is not large but will slow down the vehicle speed.

In order to solve this problem, Li Fanyu modified the rear of the car into a fastback shape similar to the previous time and space Porsche Panamera.

After making various changes, the whole car has been given a streamlined style.

This is the appearance section.

The body part uses the lightweight aluminum body used by the A8 at the time, and combines it with a carbon fiber integrated cockpit customized in the United States. An ultra-light and high-strength body is made that is further reduced in weight but greatly increased in strength.

The renovation of the interior part is the most difficult part of the entire plan.

The first engine used was based on the V63.0L engine modified by Wang Rui, with an offset ignition system added. It was combined with the electronic control unit developed by the previous three academics but not yet put into use, and transformed into a V63.0T electronic turbocharged engine.

Although the main body of the engine still uses Wang Rui's modified version, the special performance of the electronic turbine further enhances the oil-to-air compression ratio in the cylinder and solves the acceleration problem caused by the energy-driven turbine blades of traditional turbine engines. Hysteresis.

In fact, the solution is very simple; it is to control the turbine through the electronic control unit, so that even when the accelerator is not stepped on, such as when decelerating or turning, the electronic control unit will force the fuel supply system to release a large amount of gasoline. It is injected into the engine cylinder but does not ignite.

Instead, the atomized gasoline is directly allowed to enter the extremely hot exhaust system through the engine without being burned. When the atomized gasoline enters, it will automatically detonate when encountering a high temperature environment. The pressure generated will rush to the turbine intake pipe and push the supercharged air blades to continue to accelerate.

In this way, the turbine blades can be maintained at approximately 14,000-20,000 rpm even when the car is decelerating. While greatly improving the performance of the engine itself, it also solves the root cause of turbo lag.

After this overhaul, the V6 engine that had already undergone cylinder expansion and modification was completely changed again; during the test, the already abnormal engine could output nearly 320KW of power and more than 400 horsepower. Horsepower and more than 500 NM of torque.

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

This is so **** weak!

Because the task given by the system is to do its best to improve performance, so even after this magical modification, he still felt that it was not enough.

As a result, a crazier and more inhuman engine emerged - the electronically turbocharged W12!

After applying Wang Rui’s magic modification routine to the V6 engine to the W12 on the A8, Li Fanyu installed the electronic turbine after four days of continuous hard work. After the magic modification was completed and tested, there was a set of data that made the entire R&D team dazzle;

650kw!

855 horses!

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 customized ten sets of large wheels and tires from Dunlop at a high price for use in drag racing.

In order to make this violent world-destroying guy stop and slow down as quickly as possible, the R&D team is really in a dilemma - Zhengxin's existing braking system can't do it... .

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

This material is made of fibers that are treated at high temperatures to achieve an oxidation effect, and then the fibers are carbonized. The carbonized fibers are then baked at high temperatures for a long period. During the baking process, gases rich in carbon oxides are added to cause chemical reactions. Fiber and carbon oxide are perfectly blended to form a plate with ultra-high hardness, ultra-high wear resistance, and ultra-high temperature resistance.

With this kind of board, it is not enough.

Based on the performance of this plate, Li Fanyu threw out the front and rear double sets, double brake pumps and strong cooling air flow brake caliper system of the previous Spacetime F1.

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

Since during the test, every time the brakes were applied, the fiber brake pads would turn into a bright red color and emit bursts of "err" screams. The R&D team directly named this set of brakes "Wind". Fire wheel.

Yes, added baby sounds...

Coupled with the air suspension, which is connected to the electronic control system and can control the body posture and suspension height according to the vehicle speed, to enhance the grip and the quattro sports differential, which can change the four-wheel drive force according to the vehicle body posture, thus enhancing the cornering performance. transmission, and the NOS nitrogen combustion system was installed in the rear in order to compensate for the weight loss caused by the elimination of the rear seats, resulting in an imbalance in the front-to-rear weight ratio of the car body.

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