Coquettish Rebirth

A car like Highway Star can be said to have made Jia Hongjian pick a peach!Why do you say that?Because at the beginning, in order to reduce the weight of the body and reduce the difficulty of research and development, Musk and others finalized the car shell as a full-body carbon fiber material, and then the chassis was made of an all-aluminum alloy, which is integrally pressed and formed, so that the hardness of the site is relatively guaranteed, and the weight is also relatively low. The same volume of steel is much lighter!In the end, it was only 1.2 tons!Suddenly, it seems that the weight of this 1.2-ton car is about the same as that of an ordinary family car?But the problem is don't forget that our car safety requirements are similar to those of BMW, Mercedes and other cars with about 70 RMB!And for cars with the same price, BMW and Mercedes-Benz basically have to get about 2 tons!

Of course, from a certain point of view, the greater the weight, the safer it is actually - because after a car accident after rushing up, the light car must be easily damaged, while the heavy car must be in better condition.But the problem is that this is the first time to make an electric car. If the weight of the car increases, the acceleration and top speed data will look quite ugly!As a mature brand, the launch of a new car may not have any data highlights, just safety.Because such a brand already has brand recognition, consumers will still buy it.But Tesla is different. Even as reborn we know that this brand will be very powerful in the future, but don’t forget that the time and space natives in the United States don’t know it!

Moreover, such a car was only positioned to develop in the US market at first. The first thing Musk and others thought was to make a fortune in the US from consumers who are "stupid and rich"!I never thought that I could cross the ocean and come to China to sell cars!So here comes a problem, if Tesla is first launched in China, then maybe some Chinese people still have some "worshiping foreigners" habits and think that this American brand electric car may be very good!Seeing that the price is still similar to that of BMW and Mercedes-Benz, you may even think that this brand is very high-end!This is like some manufacturers of fake foreign furniture in China. The furniture is obviously made of thousands of dollars, and it is exported to European ports to stop for a while.Then re-import back to China.Show the customs declaration to consumers, and some rich people can foolishly spend more than 20 yuan to buy this broken bed!

Therefore, if Tesla had planned to launch in China, it would not have to face such a big difficulty in sales after the product was launched just because of the gimmick of a real American brand—at least in terms of brand recognition. With such great difficulties, there will still be difficulties in other places.However, if Tesla starts in the United States and only develops in the United States at the beginning, it will encounter a problem-similar to a Chinese domestic brand that has never heard of the name suddenly jumping out and saying that they are going to make an electric car.Also sold as expensive as BMW Mercedes-Benz!If this brand of car does not have enough data highlights, who will buy such a car?Even if rich people have a lot of stupid money, their money is not just cheated!

For those who make fake foreign furniture, they have to make all kinds of customs declarations to show that their products seem to be high-end furniture imported from Europe!People still have all kinds of things that seem unforgeable to prove their brands that have never been heard of!Why can Tesla gain the recognition of the masses by relying on its own brand?Just because they are electric cars?Toyota made a hybrid car ten years ago!So whether it is to save money, or because of the idea of ​​​​making the product famous in the early stage, anyway, according to the previous plan, this Tesla car must make the data "running points" look good!Good-looking mobile phone scores can make consumers feel that the hardware of the mobile phone is awesome. Similarly, good-looking car "running scores" can also make people think that the car is awesome!

So what is the "running score" of a car?It's very simple, accelerate from 911 kilometers!Like the 2006 version of the Porsche 4.1.As a small sports car, the acceleration of this car from 12 kilometers to 3.4 kilometers is 2 seconds.Of course, such an acceleration time cannot compare with the 3-second acceleration to 911 kilometers of McLaren 911c, let alone the 7.5-12 seconds of Lamborghini's super road sports car, but as a small sports car The acceleration capability of the Porsche 4.1 is definitely one of the strongest at the same price!The most expensive version of the Porsche [-] is $[-], and the most expensive is $[-], which is basically the same price as our Tesla Road Star.The best level of the same grade is about [-] seconds, so why should we reach a similar level?Otherwise, how can we compete with BMW and Mercedes-Benz?

Out of this pursuit of good "running points", Tesla designed the electric sports car they are designing to be a relatively light body.Naturally, the lightest but still relatively strong carbon fiber is used for the car shell. Although the site is imported from the site of a small Lotus sports car.But it is replaced with an aluminum alloy die-casting one-piece chassis, so the weight can be reduced a lot!It is by such a method that the weight is reduced, thereby increasing the unit power of the entire car-the so-called unit power is replaced by an airplane, that is, the thrust-to-weight ratio!The ratio of reasoning to weight!The higher the ratio, the faster the acceleration will be!For example, Tesla is currently using the Highway Star, which is a 248-horsepower three-phase asynchronous motor provided by Daiwan.In this way, the unit power is as high as 206 horsepower per ton!

As for the 911 Porsche 06, it uses a 400-horsepower engine, which seems to have more horsepower than Tesla’s Highway Star motor, but the whole vehicle is also heavier—it reaches 1.8 tons, so their unit power It's just about 220.This is almost the same as our 206!Looking at the unit power, the two are about the same, so presumably the test scores of the final [-]-kilometer acceleration test are not too different?Not much, but Tesla's Road Star runs faster!why?Not because the car is lighter, but because of the difference between the electric motor and the gasoline engine!Why do gasoline engines rarely appear on tanks and various tractors and trucks?In fact, it is because the torque of the gasoline engine is not enough!

What is torque?In short, it is "vigorous"!The more torque, the more power this car has!For heavier units such as tanks, if gasoline engines are used, it is easy to be weak.Maybe it seems that the top speed is very high when running on flat ground, but when it is really off-road or just going uphill on the road, the speed will drop exaggeratedly!Diesel engines are different. The biggest advantage of diesel engines is that they are powerful, so maybe the top speed is not as good as gasoline engines, but in various difficult situations, its performance is definitely better than gasoline engines!As for this kind of internal combustion engine, the general torque is in a curve with the increase of speed!Moreover, the general torque is low when the speed is low at the beginning, and the torque increases as the speed increases, but when the speed increases to a certain space, the torque begins to drop again!

But the electric motor is different. Due to the structural characteristics of the electric motor, it actually starts to operate with the maximum torque from the first second when the accelerator is stepped on!To be precise, as long as the current is not changed, the motor's strength is constant!In such a case, it will lead to the fact that Tesla’s Highway Star is accelerating at 60 kilometers or the American standard of 1.6 mph—many people in China use “mile” wrongly, but actually “mile” It is the transliteration of English "mile", and one mile is 60 kilometers, so if the speed of 96 miles is actually converted into kilometers, it should be 97-60 kilometers per hour!Europe and China mostly use 60-kilometer acceleration, while countries like the United States that use the British system use 911-kilometer acceleration data.Regardless of whether it is acceleration from 10 kilometers or 911 mph, the acceleration speed of the road star in the early stage is much faster than that of the Porsche 4.1!It can be said that the early stage is several positions ahead!In the middle and late stages, it will be slowly caught up because of the disadvantage of 4.05% less unit power.But even so, the Porsche 911 accelerates to 0.05 kilometers in [-] seconds, and the acceleration from [-] kilometers to our Road Star is also [-] seconds!But it is [-] seconds faster than the Porsche [-]!

If this data is taken out, it will definitely attract people, right?After all, it runs faster than the 911 Porsche 06!The shape is not worse than the Porsche 911!Everyone is a two-door four-seater sports car, and they all aim at the high-end market. Our running data is better than others. Why can’t this attract consumers?For ordinary consumers, if they see a new brand of sports car and don't want to buy it, on the one hand, it may be because the new brand of sports car has no technical accumulation and various performances are not good-although they really bought this kind of car. Few people can drive to the point where they can display the extreme performance of the car, but people will demand this kind of performance!Seriously, it doesn't matter whether it's 4 seconds or 14 seconds to accelerate from 911 kilometers, whoever buys a Porsche 10 will fight for 14 seconds if he can meet it in his life?If you drive ten seconds slower, will you lose hundreds of thousands or will your life be at stake?None of them are professional racing drivers. Why are they pretending to be big-tailed wolves who value performance here?But people will say that whether you can use it or not is one issue, and whether you have the ability is another issue!Even if I won't use it for the rest of my life, I feel that my car has that kind of ability, which is very cool and comfortable!When I drive this car on the road and see other people driving a car that accelerates to 4 kilometers in only [-] seconds, but I drive a car that accelerates to [-] kilometers in [-] seconds, this is a sense of superiority that arises spontaneously!

And our road star is now the basis for them to have a certain sense of superiority!Under such circumstances, if you add slogans such as new energy, zero emissions, and caring for the earth, wouldn't it be more attractive? (To be continued..)
