Chapter 283 challenge topgear

Zhang Yunfeng's most urgent need now is to add some gimmicks to the high-end models of S3 to attract the competitiveness of the world. With the new four-wheel drive system, human-computer interaction software and the current 2.5t turbo engine, the power performance and handling performance of this car can definitely improve a lot. If you really want to awe the national media with a history of 100 years of automobile I'm afraid that's not enough.

Zhang Yunfeng has carefully studied the magazine "car history". The taste of the magazine for the whole car can be said to be standard Americanization. What kind of model can attract their attention and cater to their appetite? First of all, all road SUVs, Americans have no temptation to drive cars with high power, large displacement and strong passing force. Even in today's energy-saving and emission reduction era, even when most people buy economical and practical cars, their pursuit for cars is still the same. They can drive the environmental protection hybrid like Toyota Prius, but what they yearn for is still Hummer Lincoln and other muscle goods.

In addition to all road models, Americans, like people all over the world, like Ferrari, Lamborghini and Bugatti, love high-performance Street bombers. The so-called Street bombers are just like the super running of Ferrari, Lamborghini and Bugatti. The noise of the engine can be heard throughout the street. Performance has always been one of the pursuits that car lovers all over the world will never decline.

To this end, Zhang Yunfeng is also going to use the high-end S3 to cater to their appetite. The same is true for the three fuckers in top

gear. If he sends them the most environmentally friendly car in the world, Jeremy Clarkson's shit will exclaim: "I doubt if I am in an electric wheelchair..."

Therefore, as for the whole vehicle, the top equipped S3 is the best choice to conquer these two media, and Zhang Yunfeng is also ready to give these people an unforgettable surprise. He decided to add another turbocharger to the top equipped 2.5t power S3 model.

In other words, he wants to create a 2.5t, twin turbo, but the horsepower can reach 420 horsepower or more. His engine is made of the latest aluminum alloy, so he doesn't need to worry about the engine bearing capacity. The twin turbo can still run happily. If the host of top

gear sits in a 2.5t engine unprepared In the car, so a foot of gas down, enough to make them stunned.

For this reason, Zhang Yunfeng made Xiaoer use of the high-precision machining center to create two sets of 8-speed manual transmission almost by hand. This gearbox is the world's top in terms of technology content and manufacturing technology. Its changeable combination mode and extremely flexible gear shift can perfectly enlarge the engine's torque, starting speed, front, middle and back three sections The acceleration will be significantly improved.

This transmission is prepared for the future S4 and better models, but in order to achieve the shock effect first, he decided to use this transmission first in his own special top matching S3.

With the newly developed gearbox, Zhang Yunfeng flew to Chengdu. On the general assembly line, Zhang Yunfeng upgraded the hardware of the car's central control system, and further upgraded the "hande" four-wheel drive system. After the design and upgrading of the second grader, the central differential lock is equipped with a precise and incomparable measurement and control system, which can be based on the actual road conditions and the line set by the user Car model, the most scientific, accurate and reasonable distribution of the power of the four wheels, also greatly enhances the passing capacity of the car.

There are five driving modes preset in , But here in Zhang Yunfeng, the second child is a super accurate simulation computer. The results of his test are absolutely the most accurate and scientific.

After the completion of the hardware part, Zhang Yunfeng began to build the human vehicle interaction system. In order to realize the intelligent control of the car, the junior two developed two modes of the human vehicle interaction system. The two systems are A1 and A2 respectively. A1 is the internal interaction, mainly the interaction between the driver and the central control system, but it will not involve the Internet.

The driver can use the language to give instructions to the car. Through the voice, the central control computer can control all the electronic parts of the car. For example, it can switch the terrain mode of the car, activate or turn off the cruise, switch and control the air conditioner, DVD and radio. In combination with the navigation module and the built-in map information, it can directly put forward any map aspect to the computer For example, where and how far is the next gas station. Where is the nearest restaurant. Or the most direct, I want to go somewhere, how to go.

Even, the driver can let the computer control the seat position and temperature under his buttock. As for A1, a stand-alone system, it can control any electronic part of the car.

As for A2, it is the human-computer interaction system to be developed in the second step in the future. A2 will let the car access the Internet through the hardware terminal and the service of the operator. When the user has any non vehicle related needs, the system will directly submit the user's problems to the server, and the server will respond, and the instruction Library in the server will be unimaginable The A2 interactive system can give the most accurate and timely answers to most of the driver's questions.

Zhang Yunfeng has been in Chengdu for ten days. When the sophomore put a CPU with a processor frequency of 2.0g into the S3 car, the two top customized versions of S3 were finally announced to be completed. And the derivative model of the customized version of S3 is S3 C, C, which means custom, that is, customization.

At the first time when the car was offline, Zhang Yunfeng sat in a s3c, started the engine with one key, and the engine immediately responded. However, the s3c in idle and static state could not hear any difference from the sound. The full-length staff was waiting with their breath held, while Zhang Yunfeng gently put the D gear on, and then pressed the human-computer interaction button on the steering wheel.

"Ding."

The car audio immediately gives a very clear and short prompt, which means that the A1 interaction system has been started, and the driver can issue instructions at will.

the performance of this central control system is equivalent to that of a 3000 yuan desktop computer, and it ignores the graphics card. However, 90% of the processing capacity of the whole central control system is allocated to A1 interactive system, which means that the internal command base of this vehicle alone is unimaginable.

"Switch to sport mode." Zhang Yunfeng said softly.

Four noise reduction microphones hidden in the car roof compartment and the driver's seat can easily capture what Zhang Yunfeng said. Even the command in a low voice can be immediately obtained and executed in the blink of an eye.

"Switched to sport mode."

Zhang Yunfeng added: "play AC / DC" it "s

along way

to the

top"

there are a lot of songs that Zhang Yunfeng likes in the 2TB hard disk of the car. At one command, you don't have to search one by one. It's almost a millisecond. The system doesn't give you any hint to try to listen. The hard rock song AC / DC is played through the car stereo.

Then, Zhang Yunfeng released the brake pedal, and the car began to slowly move forward with idling speed, slowly out of the factory. Zhang Yunfeng stepped on the accelerator pedal, and stepped down the accelerator one third at a time. Because the car has been set to the motion mode, the accelerator is very sensitive, and the engine idling speed is also slightly improved, and the car immediately gave a very good result Strong response!

!

The acceleration time from 0 to 100 km is only 4.3 seconds, which is very difficult for medium and large-scale double seat and four door vehicles. However, the gear change of the gearbox of the car is too smooth to imagine, and the speed of the car keeps climbing, soon reaching 150 km.

At this time, the straight road in front of the workshop has come to an end. Zhang Yunfeng didn't step on the brake, but just released the accelerator. Then he made a high-speed bend. When the car turned, the requirements for the transmission system and suspension were very high. The transmission system monitored the grip and power distribution of the four wheels in real time. According to the speed and angle when turning, the power distribution should be changed rapidly so that the vehicle can Enter the curve at the fastest speed and the most stable attitude, and then rush out of the curve at the fastest speed.

The top engine, the top four-wheel drive system, the top gearbox and the top power distribution mode make the car still very stable when entering the corner at high speed. The shape design gives more downforce to the car, so that the car body is still stable in high-speed operation. Zhang Yunfeng quickly exits the corner, and then immediately increases the throttle. The gear of the gearbox is constantly changing Climb up. When you reach sixth gear, the speed has reached 230 km.

This is a big straight road with the same length as the whole factory. It's more than three kilometers long. Zhang Yunfeng gradually steps on the accelerator. When the car climbs to the seventh gear, the speed is 250 kilometers. When it climbs to the eighth gear, the speed has reached 280 kilometers.

In the blink of an eye, it's almost the end of the straight road. Zhang Yunfeng steps on the brake and the car decelerates steadily. When the speed drops to 150 kilometers, Zhang Yunfeng enters the corner again at high speed.

When the car drove to such a large parking lot, Zhang Yunfeng stopped the car, a stream of blood gushed from his chest, took off his mouth and said: "little two, this car doesn't sell to 1.3 million, I'm a fool! That's a lot more than what I'm aiming for in S3, which is a maximum of 700000 yuan... "

Xiaoer said with a smile: "boss, don't forget that this car is s3c, special top matching version. In the mass production S3, we only use 6-speed gearbox and 2.5 single turbocharged engine at most. Moreover, the four-wheel drive system won't be so high-end. If you change the shell and change the chassis a little, you can be regarded as S4."

Zhang Yunfeng nodded and said with a smile: "launch such s3c to authoritative media, let them see our high-end manufacturing capacity, top eight speed gearbox, unparalleled four-wheel drive system, which is enough to surprise consumers. First, use S3 to make a stunt, which can not only make consumers have an amazing psychology for Dongchen, but also make them more look forward to Dongchen More high-end models. "

Xiaoer smiled and said: "people all over the world like cars are the same, even if he drives a three
