When he saw the staff of the Wind Tunnel Laboratory delivering the data collected this time to their hands, Sun Ying and the engineers behind him could hardly look through the various data.

Through various tests of this concept prototype car concept.f, the resistance coefficient of this prototype car was calculated, which was only 0.198!

What is 0.198?

Generally speaking, the resistance coefficient of a normal car is between 0.26 and 0.35, while the Suv model is between 0.3 and 0.4. As for the F1 racing car, it requires a braking time of less than 1.4 seconds because it requires a brake time from 100km/h to complete stop. The braking distance is about 17 meters. At 200km/h, these two values ​​are 2.9 seconds and 65 meters. From 300km/h to a complete stop, it only takes 4 seconds in total. Under such high intensity, the driver's deceleration in the horizontal direction is close to 5.4g. This requires the F1 racing car to generate enough downforce, so its coefficient is much larger than that of ordinary civilian cars, around 0.6 to 1.3. Therefore, the design of resistance coefficients is also added in local places, such as front and rear spoilers, etc.

As for supercars, because the same reason as f1 racing cars is that they need sufficient downforce, their resistance coefficient is above 0.3.

As far as Bai Ningyuan knows, the Mercedes-Benz E-Class in the world's mass-produced cars has the smallest resistance coefficient among mass-produced cars. It reached a terrifying 0.23. As mentioned earlier, it is extremely difficult for engineers to reduce the resistance coefficient by 0.01. So God knows how much effort the Mercedes-Benz engineers have put in to achieve such data. You must know that Mercedes-Benz is one of the few car manufacturers in the world that owns its own wind tunnel laboratory.

Even Tesla models, which are also electric vehicles, have a resistance coefficient of only 0.24.

It can be said that the drag coefficient of this prototype car is enough to satisfy Sun Ying and others. No, it should be said that it is beyond imagination.

However, this is just a concept prototype car after all, not the final mass-produced version, because there will certainly be corresponding adjustments and changes during mass production. It is expected that by that time, the resistance coefficient will probably be similar to that of models.

After all, the concept of electric vehicles between both parties is the same, that is, to pursue higher endurance.

However, Tesla's models have not yet been launched at this time, so for Sun Ying, such a result is enough to make them feel proud.

After receiving this report, Sun Ying almost couldn't wait to send the electronic version of the report to Bai Ningyuan's email address.

For them, this wind tunnel experiment was a great success, marking that their hard work of forgetting to eat and sleep for so long has finally been rewarded.

Of course, the current success is just a node in their new model development process. What a long and arduous road awaits them in the future, but at least now, they are satisfied!

The success of the wind tunnel test now means that the next step is to officially start the construction of the concept prototype vehicle. After the chassis, motor, battery, battery control system and other electronic equipment in the vehicle are all developed, the final unified test will be conducted, and various data will be collected for redesign and adjustment, and then the various data indicators and appearance standards of the mass-produced vehicle will be determined.

According to the internal time plan of emp car industry, their goal is to make this concept.f officially unveil the Beijing International Auto Show in May next year for a static display, and then officially launch this concept model at the Shanghai International Auto Show in 2007. As for the final release of the mass-produced model, it is estimated that it will also be at least 2008 Beijing Auto Show.

Seeing that there is less than half a year before the Beijing Auto Show, it can undoubtedly be said to be a very arduous task and challenge for emp's R&D personnel.

Fortunately, the appearance design has been verified, and the chassis and battery equipment are not visible in the static display, so it is not impossible to complete.

At this time, Bai Ningyuan, who was in the capital, had not recovered from the excitement of successfully obtaining Alibaba's equity when he received the report from Sun Ying.

A few days ago, Gaosheng's financing plan was officially completed. After paying 18% of Alibaba's equity and 8 million US dollars in cash, Gaosheng officially acquired 20% of Letu Software's shares.

Seeing that the career he had become bigger and bigger, Bai Ningyuan felt that it was necessary to make some corresponding adjustments. It was just the last month of 2005, and the annual meeting was held next month, so some adjustment plans should be made at this time.

In addition, during New Year's Day, he was also planning to fly to Qiantang to meet with Alibaba's chairman Ma Yun. After all, it involved an 18% share transaction. It was definitely a big deal for a company, and the equity change naturally would not be hidden from other shareholders. So after the acquisition was over, Bai Ningyuan had already made a phone call with Ma Yun. The two parties had a preliminary contact, but there were many specific things that could not be explained on the phone, so whether it was Bai Ningyuan or Ma Yun, they felt that it was necessary for both parties to meet.

As New Year's Day approaches, you can also smell the festive atmosphere on campus. For these college students who are still in the ivory tower, their lives are carefree and colorful.

On campus, Bai Ningyuan still maintained a normal performance, deliberately performed very low-key, and had a harmonious relationship with his classmates. As for Sun Tongji, who had a grudge against him, although he was still a little reluctant to give in to him, he never made any profit from him. He was like Xiaoqiang, an irresistible villain in the anime, who always shouted "I will come back again" and then left in shame.

Luo Yanghui didn't have a good impression of him, but as time passed, although he would not greet him with a smile, he did not have the resistance he had at the beginning.

After all, Bai Ningyuan is at a different height. For him, these four years of college life are just a beautiful scenery in his life. It is more about fulfilling the obsession in his previous life. He does not need to worry about the future, nor does he feel that there are any interpersonal relationships that need to worry about. Since others don’t like it, he can’t make a fuss and put on his cold butt, and he feels wronged himself in vain.

The sky was getting darker. As it was approaching evening, Bai Ningyuan looked at the time and rode his electric bike toward the kindergarten in Qingmujiayuan.

A few days ago, Zhang Yan flew to the United States to attend a meeting within the company of Zuozhuo. Bai Ningyuan needed someone who he believed and had a sufficient understanding of America to act as his "instructor minister". In addition to attending the meeting, he had more of a meaning of inspecting the company for Bai Ningyuan. After all, the sky was high and the emperor was far away. In addition, for Bai Ningyuan, Zuozhuo was a core part of his future territory, and there was no room for mistakes.

Zhang Yan is not in China, so the task of picking up Nuo Nuo to go to school and taking care of her daily life naturally fell on Bai Ningyuan...
