With the enthusiasm between Li Xiang and Feng, CEO of Volkswagen China, I would like to say a few words on the topic of program enhancement technology. . .

We all know why. Because Li ONE adopts extended range technology, many traditional manufacturers regard Diss as an outdated technology with little development potential. In this regard, Li took it for granted that he couldn't bear it, and he did not hesitate to look back, and the public went back. Right or wrong, today I will only talk about the add-on program and the feeling of using it.

We are no strangers to extended-range electric vehicles. 20 1 1 Chevrolet volanda and 20 15 BMW i3 extended-range models all have similar principles-the fuel engine does not directly drive the vehicle, but only generates electricity, and then the motor drives the vehicle. The extended program is essentially a hybrid power, just a combination of engine and motor. You can say that the engine technology is not advanced enough, or that the motor efficiency is not high, but the combination of the two is not outdated or development potential, but more is whether the enterprise is willing to choose such a scheme. It seems far-fetched to define GM and BMW as "outdated" if they were used in the past and are no longer used now.

The advantage of adding programs at this stage is that you can replace charging with refueling (of course, you can also charge directly), thus saving users' time and energy. In addition, it can also reduce the mileage anxiety of users as much as possible, not to mention how long the extended warranty program lasts, but when it is necessary to replenish energy, the extended warranty program can be as convenient as a fuel truck without worrying about being thrown on the road. These two points actually expand the use of electric vehicles, so that many people who want to buy electric vehicles but have concerns can use them with confidence. From this point of view, the extension program is still very user-friendly. If fast charging stations are as popular as gas stations in China today, it is estimated that there is no chance to increase the program. It is precisely because of the imperfect infrastructure that charging is still a problem in many places, which gives the program a time window for development.

However, the shortcomings of the extension program can not be ignored. First of all, increasing the power system will increase the cost and weight. Therefore, many PHEV models produced in China under the dual-point policy often have a worrying market. Because their prices are much more expensive than those of gasoline vehicles of the same class, they only increase the pure electric battery life by more than 50 kilometers in performance, but they are not real electric vehicles, so their competitiveness is not high. For Li alone, this is not a big problem, because Li alone can deal with it without gasoline, and at the same time, it is a real electric car with dual-motor four-wheel drive and acceleration of more than 6 seconds. These are all advantages.

Secondly, the range extender is generally a small displacement engine, which has obvious vibration and noise and needs to be solved. Judging from the actual driving effect, Li solved this problem well by himself. When idling and driving slowly, the 1.2T range extender basically doesn't work, and only starts when the vehicle speed is relatively fast, so that the noise and vibration of the range extender are basically integrated into the wind noise, tire noise and body vibration caused by the road surface. Of course, many times you can still feel the vibration of the range extender from the steering wheel, but it is very slight and won't bother you.

Regardless of the advantages and disadvantages of the program itself, it is just a form of power, just like a fuel vehicle or a pure electric vehicle. This kind of power form cannot determine the product strength and competitiveness of a car, but must be combined with many other aspects to judge whether a product is excellent or not.

Finally, I want to say a few words about environmental protection. The first is the data from China Industrial Information Network. In 20 19, China * * * completed the power generation of 7.09 trillion kilowatts, and the proportion of thermal power/hydropower/nuclear power/wind power was 72.83%/16.26%/4.91%/5.99% respectively. Although the proportion of thermal power is decreasing year by year, it is still a large part. Secondly, the problem of carbon emissions should be concerned and solved by the state and enterprises, and consumers should not be expected to have such a high level.

I think it is a bit serious to say "contradictory". The public's comments are definitely not aimed at ideals, because the levels are not equal. The extended-range vehicle is really just a transitional product on the electrified road and cannot be the ultimate goal.

Just listed in the United States, Li Xiang sensitive can understand at once. A little trouble will bring fluctuations in the US stock market. If he wants to become a hot spot like Musk, he needs a more advanced method.

Back to the product, there is a difference in efficiency between plug-in hybrid and engine extended range. When the extended range engine is only used to convert electric energy, the efficiency loss is greater than plug-in hybrid. In addition, there are also great differences in cost, because the current cost of batteries determines the cost of the whole vehicle. The cost of a battery that can run 50 kilometers and a battery that can run 400 kilometers is clear at a glance, which is part of the reason why traditional car companies give up extended-range electric vehicles. So don't just look at the performance comparison on the surface, but look at the cost and efficiency behind it. I believe that the ideal product should still choose pure electric vehicles.

It is good to have an argument, but the reason is not clear. However, in the past, there was little "communication" between automobile manufacturers. Now it has gradually become the norm, indicating that everyone is under great pressure. On the one hand, it shows that the route dispute is becoming increasingly fierce, on the other hand, it also shows that traditional automobile companies are abandoning their previous practices even if they are as cautious as Volkswagen. From a historical point of view, extended-range electric vehicles are destined to be over-products, because there is no special core technology, the engine is not excellent, and the motor battery is not beyond the scope of pure electric vehicles. Therefore, the fate of extended-range vehicles actually depends on the popularity of pure electricity and charging network infrastructure. If pure electricity develops well, the life cycle of the extended-range vehicle will not be too long.

It is also the normal state of the Internet society. Actually, there's nothing to make a fuss about. If we really want to talk about environmentally-friendly cars, I'm afraid there are no truly environmentally-friendly cars on the market. Yes, pure electric vehicles are not "green cars" either, because the power supply based on non-green energy will cause environmental pollution in the upstream and downstream, especially in the case that more than 70% of the power supply in China is thermal power generation. Pure electric cars are like this, not to mention cars that need to burn gasoline. Therefore, this is a question of two different development ideas. The public is talking about environmental protection in a broad sense, and the ideal is more focused on the specific product level, so there is nothing wrong with both. Don't take the so-called reaction too seriously In today's society, everything is purposeful and dramatic. So, let's be a bystander. Maybe there will be a new one in three days.

Needless to say, I also saw a Li one in the garage below our community. In a city where it is not a pure tram, it is the same as a fuel car. This is really true love. Speaking back to the event that Li wants to challenge the public, I think there is nothing wrong with the normal debate around the technical path, and it is boring to talk too much. As for whether the extended-range car has a future, it is valuable at least in the short term. If there is only one car at home, it looks a little more reliable than pure electricity at this stage, but I won't buy one for Li because I have a gasoline car that I think is perfect to drive. I don't hate some traffic stars, but I really hate their fans. The above also applies to several new energy car companies, such as Tesla, such as Weilai, Ideal. To tell the truth, these brands have product strength. Some fans are really speechless. If you say you can drive your own car, you are finished. If you have any questions from outside, brush them up immediately and call names under Weibo. Birds of a feather flock together, just for some such fans, I won't consider these brands.

I don't think there is anything to worry about. The future development trend of automobiles is definitely not just pure electric vehicles. Beijing's planning has already mentioned hydrogen-powered cars! ? So stick to yourself. If you think the extended journey is the direction, do it./kloc-See you in 0/0 years. ? Foreigners are basically prepared with both hands and need electricity. Now the technology is relatively mature and the subsidy is large; Fuel cells and hydrogen power should also be stored, which may be useful in the future, but we really haven't seen any technical reserves to expand the scope. Therefore, China's refueling will lead the future technical direction, so it should avoid listing in the United States, otherwise it will be easily sanctioned like Huawei.

This kind of opportunity that can cause spontaneous media hype is rare, and it can be regarded as a propaganda resource. But it's fire, and you must take risks to play with it. However, this time both sides had a good time and didn't burn anyone. Li believes that he must clearly defend the extended-range electric vehicle plan, because that is his business. The public is more concerned about this "spokesman". As an executive of an engineering manufacturing enterprise, he talks about his views on the technical route based on his professional knowledge. I don't see any strategy here. Volkswagen is currently in a difficult period in electrification. Their MEB is not going well. The reason is that its system is fuel-fired, not electric. Under pressure, the choice of electric technology route can easily become a topic that people are willing to talk about. Because it is natural to talk about it, and institutional issues are politics and taboos. Of course, Li Xiang's response is very sure, and even his argument is completely in line with expectations. This just provides the outside world with the "ingredients" you expect. You see, the editor-in-chief made a dish with it. Isn't it delicious?

Speaking of extended-range electric vehicles, I came into contact with them as early as 2009. At that time, I was driving a Chevrolet Volt at the General Motors headquarters in Detroit. At that time, I thought this car was a transitional product. Sure enough, the market performance of Volt in North America and China is obvious to all. Even with a subsidy of $7,500 in North America, sales are still bleak. After that, GM decisively stopped the extended-range electric vehicle project. In fact, it can be seen from the failure of GM a few years ago that the extended-range electric vehicle is only a transitional product. Judging from the current battery technology, this is something that should have been eliminated long ago. In other words, it is essentially a hybrid car, not an electric car.
