My wife is the first owner of the domestic Tesla Model 3, and has been driving for nearly three years! Therefore, for this brand, I have a certain right to speak.
Tesla is currently the most optimistic new energy vehicle, and its positioning is also high-end. I don't know what the reason is, at present, a large number of people on the Internet tout Tesla, whether they have driven Tesla cars or not, as long as they see that there are many people on the Internet who say yes, they also follow suit.
As a result, Musk himself did not blow much, and a large number of netizens held Tesla to the sky.
Admittedly, Tesla has many advantages: sleek, powerful, and more intelligent.
At present, everyone is most concerned about the endurance, Tesla can also improve battery efficiency and extend battery life through the leading level of electronic control. The excellent shape design makes the air resistance of the whole vehicle as small as possible. In this way, Tesla's battery efficiency has increased, and the power consumption rate is relatively low, so it is always better in the endurance.
All of the above are Tesla's advantages, and I also admit it.
In fact, if netizens repeatedly blow on Tesla above, I have no opinion.
However, in addition to the advantages of blowing the above, many netizens also blow some very mysterious things: design concepts, driving experience.
I just want to ask, a lot of netizens who have not touched Tesla cars, do you know what is the design concept?
As for the driving experience, in fact, what I want to say is: the car is only a means of transportation after all, is it possible to experience the driving experience of a Tesla, which can make the driver's soul fly out of the sky? Be in ecstasy?
In fact, I have no opinion on Tesla, and I also recognize many of its advantages, otherwise our family would not have bought it in the first place. I just don't understand those who have never touched Tesla, all day without thinking, very unobjective at the same time, but also unanimously look down on their own domestic cars.
Now, I'm listing Tesla's shortcomings, so that those brainless blowers have nothing to hide!
First, Tesla, as a pure electric new energy vehicle, has not solved the problem of mileage anxiety.
What is the problem with pure electric new energy vehicles, everyone knows.
In the case of our Tesla Model 3, the standard endurance is 445 kilometers. If 3 years have passed, the full power endurance is displayed at 420 km.
Therefore, Tesla can not solve the problem of battery attenuation.
Turning on the air conditioner in summer, you can run 100 kilometers of electricity, which may only be enough to run about 70-75 kilometers.
Running at high speed, you can run 100 kilometers of electricity, which may only be enough to run about 75-85 kilometers. Depending on how fast you run, the lower the speed, the slighter the endurance shrinkage.
Charging, fast charging from 20%-80%, but also about 50 minutes.
Since I am a southerner, I cannot verify the shrinkage of the endurance in the low temperature in winter, and the specific degree of shrinkage. But what is certain is that Tesla cannot avoid the problem of shrinking battery life caused by low temperatures in winter.
Therefore, although Tesla has done a better job in terms of endurance, it has not solved the problem of mileage anxiety.
Well, these are the common problems of pure electric new energy vehicles, although it is a disadvantage, but it is not the fault of the Tesla family!
However, Tesla has not made any effective efforts in this regard!
Weilai automobile, although it is also expensive to sell, but at least the power exchange model introduced by others can largely solve the problem of mileage anxiety.
Ideal car, extender car. There is a pure electric range of about 100 kilometers, and after the power is consumed, the fuel will drive the generator, power the body, and can also solve the mileage anxiety. In addition, if you use a car to commute to work in the city, you can charge it every day, and you can completely eliminate fuel consumption.
BYD super hybrid. By the two words of hybridization, we can know that also solves the mileage anxiety. Similarly, the super hybrid also has a pure electric mileage of about 100 kilometers, and if it is used for commuting in the urban area, it can also be basically refueled. Moreover, the super hybrid car, in the state of power loss, the fuel consumption is only about 3.8-4.5L, which is lower than the dual engine of Japan's decades of technology.
Like Weilai's power exchange mode, itself is an important direction to solve mileage anxiety, and it is also very feasible.
The ideal range extender and BYD's super hybrid, although you can use oil, but in many scenarios you can not refuel.
These are the efforts of our country's new energy vehicle companies to solve the mileage anxiety.
And Tesla is very willful, like Apple, my battery is not removable! To disassemble to find me, one hundred and eighty thousand! Therefore, Tesla did not want to solve the problem of mileage anxiety through the power exchange mode.
And range extenders and super hybrids, Tesla will not consider.
Well, who let Tesla be the boss now! So, how good is Tesla's own endurance? Can you completely ignore the problem of mileage anxiety?
It's pretty outstanding! The million-priced Model S can achieve an endurance of 652 kilometers!
But it is a pity that the best in terms of endurance is not the Tesla Model S, but the 200,000-level Xiaopeng P7! Xiaopeng P7 can currently achieve an endurance of 670 kilometers! The 2020 Xiaopeng P7 can achieve an endurance of 706 kilometers.
Therefore, Tesla, like other pure electric new energy vehicles, has not solved the problem of mileage anxiety. However, it is arrogantly unwilling to take some compromise solutions, and does not pay enough attention to the needs of users in terms of battery life. In terms of the pure electric mileage of the vehicle itself, Tesla is not the best.
Second, Tesla is not doing well in terms of safety performance!
Tesla's safety performance is not outstanding, mainly reflected in four aspects.
1, the well-known brake failure problem!
In fact, judging from the results of the investigation of many accidents, a large part of the reason is that Tesla has adopted a single-pedal mode with energy recovery functions.
The so-called single-pedal mode means that during driving, braking (braking) can be achieved simply by releasing the accelerator pedal (throttle). Over time, the owner gets used to operating only one accelerator pedal most of the time.
This is actually a big security risk! Because, in the event of an emergency, the braking force generated by simply releasing the accelerator pedal is not enough to make the car achieve the braking effect it wants! At this time, in the subconscious of the owner, it is enough to release the accelerator pedal! At this time, the foot that originally left the accelerator pedal and went back to look for the accelerator pedal... This is the fundamental reason why many Tesla owners use the throttle as a brake!
It is conceivable that if in an emergency, the owner's reaction is to want to brake, and the result is that the car rushes out.
2, Tesla's autopilot problem.
Although the technology of fully autonomous driving is not yet mature, Tesla has an AP automatic driving assist function. This function is suitable for use at high speeds or with few traffic lights. In this state, it is possible to change lanes automatically + cruise at a fixed speed.
However, as soon as you touch the steering wheel with your hand, the automatic lane change function is removed. If you slam on the brakes, even the cruise control is lifted.
This function, when my wife was at high speed, did not dare to use it once! I've used it a few times, and I just want to experience it, but I basically don't use it.
Because, we are not at ease to give our lives to electronic products.
I would like to ask, what should I do if I crash? What should I do if the camera or line fails? The car will encounter a relatively large amplitude of vibration in many times, and after a long time, who can guarantee that the position of the camera has not been offset? Who can guarantee that the function of the radar has not been compromised? Who can guarantee that the line will not be damaged in those places that cannot be seen?
Although these are small probability events, they are not allowed as long as they occur once.
Of course, people can also go wrong, but we drive by ourselves, tired can rest, bad state can also rest. Therefore, with the current technical conditions, it is more reliable to drive by yourself!
3. Tesla's central control design problem.
Tesla has no dashboard! Therefore, the large and small functional buttons of the car are all changed to be operated by the large screen in the middle.
This, in fact, is a big security risk.
First, if we want to see what our speed is, we have to twist our heads towards the central screen. This is not conducive to the concentration of attention! Tesla itself accelerates relatively quickly, which increases the danger of doing so.
Secondly, many functions to operate the central screen, you need to operate the phone, page turning, looking, operation. This is far more dangerous than the multiple button distribution of previous traditional cars! Because, the multiple buttons of traditional cars are distributed, we have memorized them and can operate blindly! And in the way of screen operation, the owner cannot operate blindly! There must be a certain amount of time to focus on the screen, which is undoubtedly a security risk.
This is the product designed by the advanced design concepts mentioned by countless brainless blows on the Internet! I would like to ask: Is it reasonable? Is it safe?
4. Battery safety!
At present, Tesla uses high-nickel ternary lithium batteries! The battery of new energy vehicles has the risk of spontaneous combustion! Of course, fuel vehicles also have the risk of spontaneous combustion. However, the harm of spontaneous combustion of new energy vehicles is much higher than that of fuel vehicles.
Because, the fuel vehicle spontaneous combustion, mostly from the fuel tank. If extinguished in time, important components will not be damaged.
If the new energy vehicle spontaneously combusts, it is from the most expensive component - the battery! With the importance of batteries to new energy vehicles and the retention rate of new energy vehicles, if the batteries of new energy vehicles spontaneously combust, it almost means that the whole vehicle is scrapped!
This is not the most important thing, the most important thing is that the battery burns very violently, often burning a car into an empty shell within a few minutes. Therefore, the car owner can evacuate in a very timely manner.
Tesla's high-nickel ternary lithium battery, when it encounters external force squeezing, external object puncture, and high temperature environment, may produce thermal runaway and produce violent combustion! This means that if a traffic accident occurs and the battery is injured, it is very likely that the battery will burn and produce very serious consequences.
At this point, our domestic BYD blade battery, its safety is far more than Tesla's high-nickel ternary lithium battery. Knife since the battery under the external force extrusion, external puncture, high temperature environment and other destructive scenarios, the battery has not produced obvious changes!
Personally, I think that mileage anxiety issues and safety issues are the most important issues, so I highlight these two aspects. But in fact, Tesla has some other problems!
Third, very unprotected value, and low cost performance!
When our family bought the Tesla Model 3, it was 35.6 million! 445 km of standard endurance!
At the same time, BYD e5, 150,000! 450 km of standard endurance!
What is even more tragic is that a year after our family bought Tesla, Musk himself reduced the price to 249,000 and upgraded the endurance to 468 kilometers! In one year, it depreciated by 100,000! The battery life is not as good as the new model! If you include depreciation, my body price will be cut off in a year!
In fact, we all know that the retention rate of new energy vehicles is low, but Tesla seems to be better. This is not the case! Because Tesla will engage in a variety of dazzling riot operations, so that the value of the body is rapidly reduced. At the same time, because Tesla's higher car price, the room for depreciation is also relatively large, resulting in its retention rate is actually very unsatisfactory.
Therefore, Tesla's cost performance is far inferior to that of domestic new energy vehicles. At the same time, the retention rate is also very low.
Fourth, the super large skylight, the summer heat is sour!
The skylight of the Tesla Model 3 is very large, too big to be true. The dimensions are 0.67 m long and 1.05 m wide, and there is a reinforcing beam in the central position. What's more exaggerated is that its rear sunroof and rear windshield are integrated designed, which allows passengers in the car to have a fairly wide field of view, and the experience is superb!
However, in the summer, the exposure of the sun makes the people in the car feel like a sauna. After getting in the car, the air conditioner was still very hot after a long time.
And if the air conditioner is turned on very large, it will seriously restrict the mileage!
Whenever this happens, my wife wants to stuff Musk into the car, turn off the air conditioner, and stuff him for two hours.
Fifth, many integrated parts, high maintenance costs!
Let's talk about what really happened in our house! It's the skylight mentioned earlier!
Since the sunroof and rear windshield are integrated design, it is very large! Once, I had a crack in the rear windshield that I didn't know how to produce, and it would leak.
Eventually, go to the insurance company, the insurance company said, I did not buy glass insurance alone, so it is not insured!
In the end, we changed the whole piece of glass, and this big piece was replaced, more than 8300! It was a flesh pain.
In addition to glass, many Tesla's bodywork also adopts integrated monomer casting technology. For example, a frame that was previously welded from multiple small pieces is now a complete frame. Such an advantage, of course, is to reduce mold expenditure, reduce welding bits, and enhance structural strength.
Due to the use of large monomer casting, it is not possible to repair damaged parts with sheet metal or substitution after a collision with the vehicle. Tesla used an innovative latch process to repair the body, that is, to cut the damaged parts and connect the new cast monomer with the latch parts to the car body.
This process will greatly increase the cost and time of repairing the car. I haven't fixed it, and I don't know how much it will take. All in all, it will be high!
Well, in fact, tesla has many shortcomings, such as: the interior is too simple, there is a sense of cheapness. The plastic smell in the interior is so great that it can't dissipate for a long time. But that's just a minor issue and won't go into isolation!
Seeing this, do you still think tesla is the god car in your heart?
In fact, we have only one brand in China's Shenche: Wuling Hongguang!
I am writing this article, not for the black Tesla, but just to say that Tesla is definitely not as godly as everyone says!
We recognize its merits and learn from its merits, which is understandable.
But we should also objectively face its advantages and disadvantages, do not blindly tout, and do not ignore the progress of our domestic cars!
What's more, those who have not driven a Tesla, what good does it do you to blow Tesla?
