Since the independent operation of the brand for more than one year, the upcoming X7 can no longer be missed. Auchan made a "super tester ultimate test" release and presented it to the media and audience at the auto show. This move of Changan Auchan is really courageous, and also let us know what kind of car Changan Auchan X7 is. At the press conference, Cai Yong, general manager of Changan Auchan automobile, also announced that the Changan Auchan X7 will be listed in the Great Hall of the people in Beijing on November 29. In the impression of reporters, this is another independent brand product released in the Great Hall of the people after the red flag. As for the high standard of listing and release, let's talk about it later. Let's get to the main point first. Previously, Auchan successfully launched China's first private orbital launch vehicle, Chang'an Auchan automobile, at Jiuquan Satellite Launch Center on July 25, becoming the first vehicle product of Chinese brand to land in space. Chang'an Auchan said that during the launch, the Auchan X7 completed severe space tests on materials and paint with strong vibration, - 60 ° C ultra-low temperature and strong radiation. It's undeniable that these two marketing events are all in a big way. The launch of the X7 has reached the national and luxury level. Auchan's marketing can be described as bold and hard, but we still have to observe how much it can play, and we can't boast like some brainless media. After all, since Changan Auchan brand has been operating independently for more than one year, it has stumbled in the market and product exploration. The first cos1 ° and the first cos1 ° have not been able to make a hit, and the X7 obviously can't be missed any more. Therefore, when Changan Auchan X7 released the pre-sale price of RMB 79900-119900, it also added the sincere pre-sale and maintenance policies such as life-long free real warranty and life-long free basic maintenance. It is reported that the order before listing has exceeded 18000 vehicles, which undoubtedly gives Changan Auchan great comfort compared with cosai cos1 °. It is hoped that after the official launch, X7 will truly become Auchan's "hot money" product. But can we build a brand when we tear down a car? This time, Chang'an Auchan automobile launched the "ultimate challenge of super tester", and invited people from outside to live broadcast the car dismantling. This relatively hard core operation, which conveys positive energy to the industry, is quite worth advocating. However, in practice, this time, Chang'an Auchan only invited Mr. Wu Pei, a famous car reviewer, and Mr. Zhang Weijian, one of the first scheduled car owners, to participate in the on-site 6-hour dismantling activity. In the future, media and users need to be more involved and more open. Wu Pei said frankly that he is very familiar with the engineering team of the X7, and the overall accuracy and performance stability of the whole vehicle are well controlled. The key parts of the new car, such as the door handle and armrest box, maintain the first-class quality. In addition, the whole car of X7 adopts the "deep sea mute technology". The whole car has 40 NVH sound insulation designs. Considering the experience of every driver in detail, he is a little surprised to build a premium SUV at any cost. As for NVH treatment, 40 NVH solutions and 33 vibration solutions are adopted for floor, column, trunk and hub package of Changan Auchan X7, and NVH fine adjustment technology including sound insulation cotton, roller rocker arm, hydraulic tappet, mute chain, TVD and a number of acoustic packaging technologies is applied, which makes the actual measurement of driving noise and idling noise of new cars superior to the same Grade competitive products. However, how does the performance improvement feel? It needs a test drive to verify. In terms of body structure, Changan Auchan X7 adopts high-strength steel ring body design, with high-strength steel accounting for 75%, among which the front impact crossbeam is 1.6mm hot-formed steel to ensure the safety performance of 50km / h in front impact; the rear impact crossbeam adopts 1.0mm high-strength plate to meet the requirements of no leakage in 50km / h high-speed rear end fuel tank, normal use of fog lamp after 4km / h low-speed impact and normal opening of back door. In addition, the front anti-collision beam and B-pillar are all designed with 1500MPa hot-formed steel. The transverse anti-collision beam is made of 1500hs high-strength steel to ensure the safety of side impact. Then through the structural strengthening, reducing the material thickness, increasing the weight reduction hole, cutting off the redundant trimming, etc., the overall strength can be improved accurately, so as to maximize the safety of the vehicle. As for the front bumper, we can compare it from one data. The tensile strength of the front anti-collision beam of tnga-goa is 1180mpa, which is slightly lower than that of Changan Auchan X7. Toyota's interior is mainly 400MPa. It can be said that Auchan has caught up in the body strength, and can even break off the wrist with the top players of the joint venture brand. However, there is a small problem that if the strength of the materials is much higher than that of the joint venture brand, will there be great pressure on the cost? There is a very good tradition of cars, which is very environmentally friendly materials. The air quality evaluation standard of Changan Auchan X7 is 80 UG / m2, which is 20% lower than the national limit. Changan Auchan X7 has carried out special treatment or adopted environmental protection fabric at the instrument panel assembly, door panel assembly, all car seat assembly, all car harness, all car carpet and other places, so as to make the interior environment more healthy and comfortable. In terms of chassis, the technology of Chang'an Auchan X7 comes from the R & D center of Chang'an Detroit. As Wu Pei said, it is the same technology as cs85 / cs75 plus, and Chang'an's chassis training skill is very good. The X7 adopts the standard front MacPherson independent suspension + rear multi link independent suspension, and is equipped with the unique flexible subframe at the same level. It adopts the double chassis soft connection design, which can greatly absorb and attenuate the vibration and noise transmitted from the road to the interior space of the vehicle, and reduce the bumpy feeling of the road and the vibration and noise in the vehicle. In terms of power, the X7 is equipped with a combination of blue whale 1.5tgdi "China's top 10" and blue whale 7-speed wet dual clutch automatic transmission, with a fuel consumption of 7.4l (7L for manual gear) in 100km. As for blue whale power, the reporter has already elaborated in detail in "starting from the 200nm / L torque of Chang'an Automobile", and will not repeat it. After the first stop of "extreme challenge" and the second stop of "top quality and extreme technology", through the media and users to dismantle the car together, Changan Auchan has demonstrated the confidence of X7 in its product quality and technology. In this ultimate challenge, Auchan invited the media and users to dismantle the car together, and carried out 360 ° live show without dead corner, from the appearance, interior decoration, core three parts to intelligent safety Full configuration, detailed design, material application and configuration application of the whole vehicle from inside to outside, showing the "conscience" vehicle quality and manufacturing process of Auchan brand under Chang'an automobile. In addition, the X7 is developed in strict accordance with the development process of Chang'an ca-pds, and has passed the rigorous vehicle road verification of 5 million kilometers before leaving the factory. It has also completed the rigorous test verification of more than 3 million kilometers. Changan Auchan X7 is also in more than 10 provinces across the country, conquering typical climatic conditions such as high temperature, plateau, high cold, high humidity, etc., to verify the reliability and stability of vehicle performance in various extreme climate environments. That is to say at the conference, the whole road condition test over 8 million kilometers. We can see that, in terms of manufacturing, Changan Auchan has been in the forefront of its own brand quality through one year's upgrading and progress. From a "Buyer show" that dares to play with car dismantling, the confidence to challenge the joint venture brand has been established. As Zhu Huarong, President of Changan Automobile, said at the auto show, "there must be a battle between independent brands and joint-venture brands". At least Auchan is not afraid of rivals in terms of quality. Good face + good value + good control is the definition of X7 given by Chang'an Auchan as "new three good students" in the era of 3.0. Because Changan Auchan needs to "set a new height of 100000 yuan SUV". The appearance design won the international CMF design award, which is a proof of Auchan X7's "good face". At the same time, Changan Auchan X7 is also the first SUV with space paint. In short, it is to use a high penetration electrophoretic paint with a gloss increase of 2.3 times; it is to use an environmentally friendly intermediate coating and paint material with a VOC content reduction of 50%; the varnish has the ability of automatic repair, with a brightness increase of 20%, and a weatherability and scratch resistance increase of 50%. In terms of technology, this effect needs to meet strict standards. For example, more than nine fine processes are applied to the body of the car, and 70 robots in each new car complete the full-automatic spraying; each robot precisely sprays 45000 rpm, improving the corrosion resistance by 30%. At this point, as Shen Tao, project director and designer of Changan Auchan X7, introduced at the conference, the "micron level assembly process" provided quality assurance. What is "good value"? From a detail, we can see Auchan's intention. For example, in terms of driving experience, the rear seat backrest of the X7 can be adjusted by 10 °, which is the conclusion of thousands of all-round human-computer experience evaluations for 95% of Chinese users. As for the operation, we mentioned earlier that the Changan Auchan X7 is equipped with the same engine of cs75 plus, the blue whale 1.5T GDI engine, which adopts a 350bar high-pressure direct injection system in the cylinder, with a maximum power of 131kw and a maximum torque of 265n · M. the engine has been awarded the title of "China's top ten engine", and has installed more than 400000 vehicles on Changan cs75, cs55 and other models. In terms of intelligent technology, Changan Auchan X7 is equipped with the industry's first batch of 5g compatible intelligent vehicle chip imx8, which has higher network efficiency and accuracy, and is more able to cope with complex road traffic and emergencies. According to tan Jinlong, chief engineer of Changan Auchan Intelligent Technology Co., Ltd., the customized imx8 chip is supplied by NXP, which is 3-4 times more powerful than the previous generation imx6. At present, the chip is mainly used in 4G environment. Because the vehicle specification level chip involves the requirements of stability and working temperature (- 30 ℃ ~ 80 ℃), the requirements for suppliers are more stringent. Even the giant vehicle specification level chip like Huawei has not been made. In addition, the Chang'an Auchan X7 is equipped with the open onstyle2.0 Auchan intelligent network system, with an open application center, and based on accurate big data and user habits, it is easy to select its own applications. Listen to the entertainment needs of car owners, provide rich music resources and radio program resources, and listen to songs as you wish through voice function. More exclusive super ID intimate service, user-friendly operation control, car health self-test and other functions. Changan Auchan X7 is also equipped with a unique face recognition system of the same level, which can accurately identify the owner's identity through the external camera. When the owner forgets to bring the key, the door can be opened directly through the external face recognition, and the vehicle can be started through the internal face recognition, so as to get rid of the shackles of the key. The driving status of the car owner can be monitored in real time through the camera in the car. When the vehicle speed is more than 60km / h, the face recognition system will always pay attention to the driving status of the driver. If the driver shows signs of fatigue driving at this time, the intelligent car opportunity will immediately give a warning and even chat with the driver. From the first stop of "extreme challenge", the second stop of "top quality and extreme technology" to the last six hours of extreme car dismantling, the test ended in Guangzhou auto show. So, at the end of the day, what does this test measure? In fact, it is to test the core performance of the car - three pieces. On August 31 of this year, Changan Auchan X7 launched its first stop of "ultimate challenge", which is located in Chongqing automobile test field, the largest automobile test field in the West. Test items include: long-distance 200km / h high-speed ring road test, 40 kinds of special pavement enhanced durability road test, long-distance comprehensive road test, 6 kinds of special pavement comfort road test, emergency braking performance test, limit slope
