Automobile rearview mirror paper
"Simba" has been driving for more than ten days and has run more than 900 kilometers. If there are any new experiences, I don't think this mileage is enough at all. In this post, I will share with you a series of experiences and feelings from shopping, to making major decisions, to picking up a car, using a car, getting insurance and getting a license. Here, I would like to thank my Jingweijun Beijing Cheyouhui in particular. Everyone in the group was really patient and always accompanied me to answer my various questions. Wechat message is fast and must be returned. Here are n likes! Thanks to my FL, I can answer all kinds of questions in time and accurately, form various groups in time and provide all kinds of services for me. Thank you!

The car is starry blue, and it was first charged at Weilai Super Charging Station as a souvenir.

1. Did you meet for the first time in dim light? First, let's explain the situation. There is a petrol car at home. Watching all kinds of positive and negative news about electric vehicles every day, I always have a strong feeling that electric vehicles will definitely replace traditional fuel vehicles in the future. After all, from the perspective of getting rid of oil control, electric vehicles are definitely a mainstream trend and direction. As for why, it is because of the oil price that can't be adjusted and the lottery that can't be ended. The fuel car at home has been used for some years, and it was left on the road several times, which made me have a strong desire to change cars. Change trains. Anyway, the economic conditions are better now than before. Changing trains has begun to sprout in my heart, and it has gradually grown into a virgin forest, and my head is about to explode. Go and choose a car. I looked at the magic car I once thought of, Cadillac SRX, what? Is it made in China? XT5 now? And a XT6 and XT4? Go and see, um, why can't you find the original feeling? It looks like a good car, but I don't love it so much (snickering). Let's look at Lexus again. The cost is not too big, but too big to bear. Let's take another look. Mercedes-Benz and Audi really can't stand the smell of that new car (except high-end models), Tesla? M3? I only took a look at this interior and totally denied it. How many dashboards does it take to buy an electric bicycle? After reading several brands in succession, I always feel a little dissatisfied. After all, buying a car takes a long time. Peace of mind, comfort and large space are the key points of my purchase. I have no choice. Let's put the purchase plan on hold for a while. Watch the news, read the posts and take your time. ? The news of a Weilai team let me know that now our country has made a racing car that can stand on the world stage. Dig deep, Weilai is going to enter the field of electric vehicles, so pay attention silently. Time jumped to the end of 20 19 and nothing happened. I took my wife to Weilai Center in Wangfujing, Beijing, and FL warmly received us. This experience made me know that Weilai really came. Isn't this the car I've been looking for? No obvious shortcomings, strong performance, extreme space, cool appearance, luxurious interior and authentic workmanship. I'm almost sure it's you. My wife also agrees with my choice. After all, this car is really good. It's this electric indicator. I have to check my queue. I was shocked at first sight, but it will take years to get there. I want to buy something that has no indicators, so I will endure it for the time being. Then every day when I am free, I remember that I should change trains. . .

Simba is waiting for me to go home at the distribution center.

I can't wait to go home.

Get ready to go home ~

2. Looking back suddenly, my name is Simba? Time flies, the epidemic is coming, and buying a car seems to be put on hold indefinitely. A few months later, the epidemic situation improved significantly. During a chat, a colleague happened to say that her index was put on hold. Hey, hey, isn't that what you want? Let's roll it up at once. What? One meal is not enough? Then two meals. . . Well, the indicators are ready! In the future, I am coming. ? I packed my mask. On a sunny Saturday in April, I came to Weilai Center in Zhongguancun. This time, I wanted to know more about it, but the result was not as smooth as I thought. I decided that Simba was you. ? The whole car booking process lasted about 5 hours, arrived at 2 pm and left contentedly around 7 pm. Here, I mainly talk about the questions I asked FL in these five hours. ? 1) Free power exchange policy, so I replaced my new car with an old battery. Did I suffer? ? Because Zhongguancun Weilai Center happens to be a power station, all afternoon, I saw at least three unlicensed Weilai (please forgive me for not knowing 6 and 8 at this time) coming to change electricity. In FL's words, many people don't care if it is a new battery. If you are not satisfied, please change another one. Contemporary Ampere Technology Co., Ltd.' s new car ternary lithium battery works at 380V V. It can experience thousands of charge and discharge cycles, and the battery capacity decreases less than 20% after 10 is used for 200,000 kilometers a year. (Weilai Automobile went on the market in 20 18, and there is no battery in 10 at present. The above data is the simulation test conclusion, from Weilai APP). After each power change, the replaced battery will be fully tested to ensure that every car owner can use it safely. ? Let's talk about batteries. Weilai adopts ternary lithium battery, and the cycle number is 1500. So what is the number of cycles? For example, every time I charge it below 50%, I charge it to 90%, so I use 0.4 cycles. If I charge from 0% to 100%, I use 1 cycle. Our country still has high requirements for batteries. Generally, the attenuation in 500 weeks is within 10%, and the attenuation in 1000 weeks is controlled within 20%. It is said (a post in the APP) that after 65,438+0,500 cycle tests, the battery of Weilai is still less than 20%, and the battery with attenuation higher than 20% will not appear in the power station. To put it more clearly, the total battery capacity is 70 degrees x 1500 cycles = 105000 degrees, 105000÷25=4200 kilometers according to the calculation of power consumption of 25 degrees per kilometer. 4200 x 100km = 420000km, which means that after 420000km, the battery attenuation can still be controlled within 20%. I wonder if Weilai has reached 420,000 km now. I think this achievement is hard-won. ? 2) How long does it take to deliver the new car? ? I waited for the first car for three months alive and vowed never to wait like this again! But now Weilai's production capacity is only delivered within 8 weeks. In the seventh week, the car was mentioned, and it was extremely difficult to wait for the bus. After the frame number came out, I mentioned the car of 1 week. ? 3) How much is the new car insurance? How to choose? ? If the gasoline car is at this price, the first year insurance of the new car is about 15000 yuan. Through various channels, we know that under certain operation, we can achieve the price of 6000+ (mainly including 65438+00000, car damage, excluding deductibles, etc.). ), of course, you don't have to worry about insurance and services. So how to choose? The specific summary is as follows. See if you drive carefully enough. If you have confidence in your driving skills, you can buy your own insurance. The price of 6000+ in the first year is really fragrant. If you are not confident, it is recommended to choose insurance. After all, with Wei as your backing, you will be more confident. If you have no confidence in your driving skills, you can also have a worry-free service. What can I do for Wei Lai? What did I choose? Of course I choose to serve without worry, so am I not confident in myself? Of course not. I usually drive very well. I have been driving 10 for many years and have not been fined several times. Then why do I choose worry-free service? The main thing is that I still want to experience how carefree I am. If you don't choose in the first year, you will have to pay 2000 yuan for car inspection, right? Therefore, I plan to serve in the first year without worry. We'll talk about the latter later. ? 4) How to choose various configurations of the car? ? This topic is very big, so I'll try to keep it simple. ? A) color? It's simple. Leave all the color choices to the queen. I don't care about any color. It's all the same to me. What? Even the queen can't choose? Then give it to the children. My children told me directly that blue looks good, so it is blue. ? B) wheels? I have always believed in the original design of this thing, and I believe that the original design is the best and most suitable. So I have no choice, no change. 19 inch five alloy wheels are enough. I wake up poor every morning. . . )? C) interior? You must choose a more stain-resistant color. You can't stand what you use every day. Wipe it every day. Brown and black ones are good, beautiful and resistant to dirt. ? D) keys? Here I want to vomit, why only give a key? What exactly is that card? How to use it? I want to apply for this card? Where can I put this card? In your trouser pocket? Take it out and stick it on the car to unlock it, and then put it on the charging board to start it? Why does it feel so troublesome? Wouldn't it be nice to put the key in your trouser pocket? You don't have to take it out and get in the car. It's so convenient to stop and press the handle to lock it. I had to pick up the car and spent 733 yuan to get another one for myself. ? e)NOMI? MATE2.0? If you have children, then choose. The children must all like this. ? F) advanced surround sound system? I usually like listening to music or something. How can I not choose? In other words, many people say that the upgrade of the optional equipment is not large. I chose it directly. Without comparison, I won't comment much. ? G) Do you like this suit? Many people say that this must be chosen. I really can't think of any reason why I must choose it. Let's talk about the heating of the steering wheel and the back seat first. Usually the car is in the basement, it's not cold. When you get on the bus, you will also be frozen for a while. I know this, but forgive me for never remembering to turn on this function in advance. Let's talk about smart incense. I don't like any smell, and I don't smell it. The smell has no effect on me. There is also a welcome light. Besides being better looking, I couldn't find a reason to spend money on it, so I didn't choose. Finally, the seat is ventilated. I'm afraid the wind will make my back ache, so it's not necessary. To sum up, I didn't choose this configuration. (in fact, it is still because of poverty. . . )? H)NP or AP? ? I think this thing is asking whether to choose, not how to choose. NP or AP have nothing to say. It took so much money to choose NP. Is it still necessary? Automatic assisted driving smells so good. At the beginning, I was absolutely optimistic about this car NP. It must be NP But it doesn't rule out that some people don't believe in software automation, especially driving safety, so it's okay not to choose, which varies from person to person. ? I) enhanced presentation kit? It is said that after choosing this, the front windshield is different from the ordinary windshield, which is really convenient. I probably experienced it through a test drive, and it felt good, concise and accurate (some people always say that HUD has too little content and is not practical, so I think simple is the best), and it also includes the automatic anti-glare of the exterior rearview mirror. Some people always like to turn on the headlights in the city when they drive more, right? What should I do if I encounter it? I usually let the headlights pass in front of me after braking, and then I followed silently, hehe. . . I also have a lamp. . At least it can help me light up the road ahead. . . ? J) signature version design? I still don't understand what this is for. Does it look nice? Personality? I don't need it at all. . ? 5) What discount can I give for buying a car? ? You must ask what activities and discounts your FL has at present, instead of seeing Weilai's online car selling model and thinking that everyone buys a car at the same price, and there are different preferential policies in each period. ? 6) car purchase reference materials and coupons? As a reminder, if you want to buy a car, but you don't have a coupon, you must find a reference before you get the coupon. This is very important, otherwise the person who gives you the coupon will automatically become your car purchase reference. You know this man well. If you don't know him, you can get 12000 points for your reference. Whether he will give you points depends on his mood. Remember! There are coupons in this world, and their approximate face values are 1.5 and1.00 million. Different people have different views on how to do it and how to do it. ? 7) 7) Is NP useful? ? Let's just say, because the actual use level has not yet reached the qualification of being comprehensively evaluated, here is just my own experience. Generally speaking, NP is trustworthy and performs very well in closed roads. No matter whether it is normal driving or traffic jam, there is basically no need for redundant operation, and the car will drive at a set speed without stepping on the brakes or throttle. When there is a traffic jam, it will automatically follow the vehicle in front. He goes, you go, he stops, you stop (if the vehicle in front stops for more than 5 seconds, you need to lightly step on the switch or press the acceleration button on the steering wheel). The most convenient way to use it is to close the innermost lane of the road, because only your right side will occasionally have inexplicable vehicles cutting in line, and sometimes the cars can't identify the fast-inserted vehicles in time, resulting in the two cars getting close together and not braking, mainly because the ultrasonic radar belongs to the identification of straight return, and the reflected sound waves can't be received when the side faces the car, and the inserted vehicles can't be identified in time. When driving by yourself, you still can't give it to NP completely, but most of the time there is no problem. As for how to describe this majority, let's just say that in the innermost lane of the closed road, I didn't encounter a situation that I couldn't identify it in time. What I didn't recognize in time only appeared when there was a traffic jam waiting in line to get in and out of the ramp. Generally speaking, the road conditions in this situation are very complicated. ? 8) Is fully automatic parking easy to use? ? After watching the evaluation video of garage 42, I basically gave up this function before picking up the car. It doesn't work at all, but I'm not willing to, so I conducted a simple test myself. Overall evaluation is available. It is no problem if the parking space is larger, but it should be noted that at present, it seems that only the parking space in the middle of two cars can be identified, and multiple consecutive free parking spaces cannot be identified. At least I haven't succeeded, and I don't know if others can. Software version 2.6.1c. ? 9) Will the new car smell good? ? The answer is yes, such a big smell. However, some data posts on the APP indicate that the air has been detected and the air is qualified. . . As for how big it is, it is the same level as my colleague's new Audi Q5. To tell you the truth, I'm disappointed here. I'm really disappointed with such a big taste. Fortunately, it's been a week since I picked up the car. Daily exposure+leaving window seams+ozone deodorization. I didn't open the window for two days because of the rain. The smell in the car is acceptable now, but it's not enough for me. Let's continue to bask in the sun and ozone. Forgive me for not looking for a professional organization to test the air quality inside the car, mainly because I am lazy. . . ? 10) Anxiety about endurance and mileage? This thing, let's talk about data first. At present, the vehicle travels ***554km, and there is still 54% electricity, which is 90% of the upper limit of charging, and the high-speed road conditions are not more than 300km (including the urban closed loop). Other urban road conditions, including traffic jams, cost a total of 154.36 yuan, most of which were public charging piles downstairs at home. It's equivalent to 0.3 yuan per kilometer. According to APP statistics, due to the distance between our home and 1 1km, the average power consumption is 2.0-2.4 degrees each time, which is equivalent to the power consumption per 1.8-2.2 degrees, and so on. The 70-degree battery is set with 90% charging capacity of 63 kWh and the remaining 10 kWh to relieve mileage anxiety. If there is a high speed, it may be better to use NP without speeding. Because there is a charging pile downstairs at home, although the cost is not low, there is no mileage anxiety when using it, so I didn't change the electricity. There is a power station 500 meters downstairs. . . A little wasteful. ? 1 1) About the installation of charging piles? Charging piles play a vital role in every electric vehicle. I'm not sure about other places. Let me talk about the installation in Beijing. The installation process of Weilai charging pile is like this. After the vehicle is finalized, there will be the owner's task. One of the tasks of the owner is to apply for the installation of charging piles. In most relatively new communities, you can apply for installation as long as you have a fixed parking space (including rent and purchase). The application must first be conducted on-site investigation. Weilai staff will go to the community you want to install to confirm whether the community has the installation conditions. If yes, go to the property and issue an installation approval certificate. Then you can apply for a special charging pile meter at the State Grid APP. Here you need some necessary materials, such as car purchase contract, parking space certificate, ID card, etc. It is free to apply for charging piles and meters, and then fill in the electricity contract, business acceptance form and other documents. In a few days, the grid staff will come to install it. After completing the installation of the electric meter, you can APPly for installing the charging pile in the app and make an appointment to wait for installation.

3. Green ID card-license plate? Because it is still in the epidemic period, it will take at least half a day to find a 790 Wei to apply for a license plate after the new car is picked up, and then it will take three days to check the cards on the spot and read some posts on the APP. The advantage is that the waiting time is shorter and more worry-free. Weilai staff will handle the whole process. Since I am not the indicator of my car, I need the original ID card of the indicator when I apply for the license, and then I need the indicator to be confirmed with the staff by video in the entrustment confirmation link, and entrust a special person to handle the licensing business. Then there are all kinds of processes. Because Weilai is a domestic car, there are 10 4S stores in Beijing that can get the license directly, and the fee is 130 yuan (at present, the price of some stores has increased due to too many licensed vehicles), so I chose the latter (I used the saved money to give Simba a second car key). The disadvantage of this license plate is that it takes a long time to book, and the specific waiting time depends on each store. At that time, bring the original ID card (agent and indicators), vehicle certificate, car purchase invoice, insurance policy, copy of indicators, environmental protection list, certificate, purchase tax certificate, extension number, health treasure and other materials to handle. Here is the purchase tax voucher. First of all, this certificate can be processed online, but it must be processed by the indicator after real-name authentication, fill in a bunch of forms, and then submit it. Another way is on-site treatment. I use the latter. I can drive 1 km directly to the third taxation office of the State Taxation Bureau of Beijing Economic and Technological Development Zone, People's Republic of China (PRC) after the delivery center comes out. The whole process takes about 2 minutes. There are many parking spaces in the hospital, and few people handle business. I just went in to submit the materials. The staff picked out the required materials, left some and told you that you can go. When I finished, I asked with a vague face and didn't give me a receipt. The staff patiently told me that it is all online now, and it is all online filing. You can get on the card directly, and you don't need anything. I was afraid of rollover, so I called the 4S shop I reserved and asked. The answer I got was that all I had to do was apply, and I didn't need any receipt, otherwise I couldn't get the license plate (many people went to apply for the license plate, but they didn't pay taxes and couldn't get the license plate, so they had to do it, although it was tax-free). I was the only one who handled the whole process. I asked the staff why there were so few people, and the answer I got was that it was all by appointment, and it took about 1 hour to complete all the work of obtaining the license.

4. After all? MoMoHaw wrote 6000 words. This article is definitely not short. There are many personal opinions and some data found through various channels. Friends who are ready to buy a car or have already bought a car can look around. If there are any shortcomings or mistakes, please correct me, and welcome all kinds of bricks to shoot me. Hereby! ? Finally, I want to show you some photos of the exterior and interior.
