The subversive old drivers in the automobile industry deeply analyzed Tesla Model 3.

Che Tanjun has worked in the automobile industry for more than ten years after graduation. He is used to the design and manufacturing technology of traditional cars, and also to the design and structure of many domestic electric vehicles. In 2020, Tesla models? Since it was made in China, it has become a dark horse in the new energy automobile industry with the sales of 43,744 vehicles in half a year. As the "vanguard" of the new energy automobile industry, Tesla has indeed subverted the design of traditional cars and even domestic electric vehicles in many places. Based on this, Che Tanjun intends to deeply analyze the Tesla model with everyone? 3。

0 1. The design is fashionable and scientific enough.

Tesla model? 3 At first glance, it is fashionable, especially the front face that is completely built according to the needs of electric vehicles, and the large air intake grille that is common in traditional cars is cancelled, which looks quite pleasing to the eye. At the same time, a closeable air inlet is designed at the bottom of the front face, which can be opened when refrigeration is needed and closed when refrigeration is not needed, thus reducing wind resistance.

In order to match the design of such a small air inlet below, Tesla Model? The cooling fan of 3 is not installed vertically like a traditional car, but horizontally under the trunk of the front cabin. This is actually a design that subverts all the models of other companies at present, and it has a sense of science and technology.

In addition, it may be for the convenience of manufacturing and installation, or it may be for the sake of lightweight. Tesla models? The whole system is a panoramic glass roof, but it is not a skylight and cannot be opened. It is ok to lie in the car and look at the sky and stars. And there is a beam along the middle of the B-pillar. Looking at the stars is not as good as expected, but it is still scientific and technological on the whole.

02. Space is the bright spot.

Che Tanjun has taken apart many domestic electric cars and seen them. Many electronic devices inside occupy the space in the front cabin or even the rear cabin. Thanks to innovative electrification design, Tesla Model? 3 There is no fuse box and relay box, which is controlled by the integrated circuit and software in the front body control module; At the same time, the DC/DC converter and the vehicle charger are integrated in the position of the power battery BMS under the rear seat, and the motor controller is integrated in the drive motor, which greatly releases the front cabin space. In addition to reserving a whole space for the front drive motor of the four-wheel drive (at present, the drive motor is installed at the back for rear drive), there is also extra space for placing luggage in the front cabin. In addition, there is a lot of storage space under the floor in the trunk space of the rear cabin.

Tesla model? The body size of the 3 is 4694* 1850* 1443mm, which is actually a little petite compared with many traditional mid-size cars, but it still achieves a wheelbase of 2875mm. At the same time, because there is no common bulge under the rear middle seat, the seating space is still good.

03. The driving experience is unusual

If you are used to the driving experience of traditional cars or most electric cars in China, you will have many unusual feelings when you first come into contact with Tesla. First of all, unlike many keyless entry systems, Tesla Model? 3 you need to swipe your card at the B-pillar position to enter.

There is nothing in the whole cockpit except the steering wheel and the central control big screen, and even the traditional gear handle area is empty, which is particularly simple.

The shift lever is on the right side of the steering wheel (formerly the position of the wiper combination switch), while the combination switch on the left side integrates the wiper and the turn signal switch, which is different from many cars. Then all the control in the car can be realized by controlling the big screen, including turning on the headlights, ceiling lights, air conditioning, seat heating and so on.

It is worth mentioning that the position of a virtual Tesla displayed on the left, such as clicking the position of the trunk by hand to open the trunk, clicking the position of the front cabin by hand to open the front hatch cover and so on. Compared with many traditional ways of using car cables, it is full of science and technology.

04. Chassis also has many new technologies.

Many people think that the chassis of electric cars is similar to that of traditional cars, and there are not many new technologies. Not really, Tesla model? This piece still has many relatively new designs, such as electric power steering by wire, brake by wire system and so on.

For suspension, the front suspension adopts double wishbone independent suspension, and the rear suspension adopts multi-link independent suspension. Although there is no electronically controlled suspension, considering the price of only 200 thousand, it is still very good.

05. China powertrain

Everyone knows that Tesla has been using AC asynchronous motors in the United States. Models? Permanent magnet synchronous motor is adopted after localization. After all, there are many advantages in using permanent magnet synchronous motor in China. The total motor power of the entry model is 202kW and the total torque is 375Nm. Rear drive, the official acceleration of 100 kilometers is 5.6 seconds, which is not prominent in electric vehicles. The battery is based on the ternary lithium battery of LG Chem or Contemporary Ampere Technology Co., Ltd., and the cruising range of the Ministry of Industry and Information Technology reaches 445km. Basically, it can be said that the cruising range of entry-level models is sufficient in most use cases, and the cruising range of medium and high is better.

06. Write it at the end

Seriously, Tesla model? After the subsidy, the price is more than 270 thousand, which is worth so many cars at most. In particular, Tesla's long-standing workmanship is far from its high-end luxury image. But in any case, people who buy Tesla have taken a fancy to the high-tech sense it brings. Just like mobile phones, Apple has subverted all previous mobile phone designs and has to say that it has a deep understanding of the Tesla model? This car was later found to have subverted the previous car design in many places. From this perspective, would you be willing to buy such a domestic Tesla model? Three?
