From "tank turn" to "going out nine times", looking up to U8 has become a new favorite for weddings?
It has to be said that the development of science and technology has not only changed our lives, but also had a profound impact on folk marriage customs.
Recently, at the civil weddings in many places, the "BBA" that was popular in the past has been crowded, but BYD looks up to U8 but has become a "standard for wealthy families". This is not because of its price of more than one million or its hard-core appearance, but because of a seemingly "chicken-ribbed" function - turning around on the spot.
Why did U8 become the new favorite of weddings?
In fact, looking up to the U8 in-situ U-turn function was not understood when it first came out, many people criticized this function for its low practical value, thinking that the value of the in-situ U-turn is greater than the practical value, but the folk wedding workers have a discerning eye, see the "sense of ceremony" behind this function, and skillfully use it, becoming today's "newlywed customs".
The specific ceremony is like this, after the convoy receives the bride, every time a distance is driven, it will be 180 ° U-turn on the spot, symbolizing the newlyweds to the direction of the mother's house to thank the grace of nurturing, the groom also has to get off the car, bow down to the mother's house to worship the kindness of his parents, turn his head and drive out of a distance, turn around 180 ° again, the newlyweds get off the car again to thank him, so repeated nine times, the car turned nine times, the newlyweds knocked nine times, the wedding company called it "going out nine times", symbolizing the bride's reluctance to her mother's family and gratitude to her parents.
Look up at U8 and turn around
According to a netizen who participated in the wedding scene, the father of the bride who participated in the ceremony, a fifty-year-old Chinese character stood on the balcony and watched looking up in a circle, and the daughter and son-in-law came down and knelt down over and over again, crying heartbreakingly, which can be heard almost half a street away, which is really full of the ritual sense of kissing, whether it is the mother-in-law or the father-in-law, it will become the focus of discussion in the village recently.
It is not only a unique "one step nine turn" ability, for many wedding companies that need to shoot videos, vehicle-mounted drones are also very useful, coupled with the homophony of U8 "to be sent", so that U8 can sit firmly in the top spot of the team of relatives, and the price of the car even reaches up to 10,000 yuan at a time. In this way, the price of the two models of Yangwang U8 is 1.098 million yuan, and it can be repaid almost 120 times, and the rest of the time is also a new business opportunity that is guaranteed to be profitable.
In fact, the wedding is one of the most important moments in life for many people, and the wedding car, as an important part of the wedding, is not only a means of transportation for the newlyweds, but also an important carrier to show personality and identity.
How to achieve "going out and turning back nine times".
In fact, the principle of "tank turning" is not complicated, it can be achieved by turning the left and right wheels in the opposite direction. For example, if you want to turn around from the left side, the front and rear wheels on the left side rotate backwards, and the front and rear wheels on the right side rotate forward, and the vehicle rotates in a counterclockwise direction. The reason why some people call this function of turning on the spot "tank turn" is also because this technology has been used in the field of military tanks for many years.
Previously, some off-road vehicle brands, such as Toyota Lufeng, have borrowed this principle. The Hummer EV and Rivian also use a four-motor drive version, the Dongfeng Mengshi M-Terrain uses a four-motor solution, and Tesla's new Model S Plaid is also equipped with a three-motor drive, of which the rear axle is also equipped with two drive motors.

The difference is that although they are the same four motors, they are not equipped with independent wheel motors, but only integrate two motors on the same shaft on a motor, share a set of reducer, brake the rear wheel on one side, let the vehicle turn around the rear wheel as the center of the circle, and realize the function similar to a tank turn, although it can also reduce the turning radius to a certain extent, but the vast majority can not really achieve "in-situ U-turn", there will still be a certain turning radius, which can not be regarded as a complete sense" The tank turned around".
BYD's Yangwang U8 is completely borrowed from the principle of the tank, through four wheels of independent torque vector control, to achieve differential steering of the front and rear wheels, the left and right wheels rotate in reverse, the official said that its motor torque adjustment speed is 20 times faster than the engine, the response speed is 100 times faster than the traditional mechanical structure, and the industry-leading level has been achieved in terms of motor power and torque, providing a guarantee for in-situ turning.
Look up at the U8 wheel motor
In order to better achieve "in-situ turning", not only the performance of a single motor should be excellent, but also the performance of each motor should be more accurately controlled, which is mainly due to the different adhesion of different road conditions, and the force required for rotation is also different. On low-adhesion or slippery roads, if a wheel is too powerful or too small when steering, the wheels may slip and idle or be "dragged" and slide, while on high-adhesion roads, because the wheels are difficult to slip, it is possible to damage the reducer or even hurt the motor due to excessive torque, and may also cause more dangers due to loss of control.
At the same time, the overall control of the vehicle must not be left behind. For example, it is not difficult for a person to control both hands or feet alone, but to coordinate hands and feet to complete some special actions at the same time, it puts forward higher requirements for body control and coordination.
With real-time data such as inertial navigation, motor resolver sensor, wheel speed, steering, tire pressure, vertical acceleration, etc., as well as the fusion perception of intelligent driving sensing data such as cameras, lidars, millimeter-wave radars, and high-precision positioning, the rapid and accurate reception of various signals provides stronger data support for the decision-making and control of the "strongest brain", so that the vehicle can truly achieve the deep integration of electrification and intelligence.
And this is actually BYD's "Yi Sifang" mass production four-motor independent drive technology platform. Not long ago, on the 2024 Dream Day, we also saw a Yi Sifang concept car displayed by BYD on the spot, its biggest feature is that it directly cancels the traditional steering gear and braking device, and through the drive, braking, and steering three-in-one technology, it completely relies on the independent drive technology of Yi Sifang and four motors, and realizes braking and steering without relying on the traditional mechanical structure, allowing us to see the strong strength of this technology.

In addition to these "black technology" imagination part, the easy Sifang platform is also very good in terms of practicality, the four wheels work independently will also make the vehicle have a stronger four-wheel drive off-road ability than the fuel off-road vehicle, after all, if the four wheels work independently, not only will not lose power because of a certain wheel stuck in the mud, but also provide each wheel with the most suitable power output for the current road adhesion, so that it can better adapt to different road conditions, which is also very practical on the road to pick up relatives.
There will be more and more examples of "tank turns" becoming "going out nine times".
I'm afraid that when the launch of the U8, BYD would not have thought that its products would be integrated into people's daily life in such a way, changing the traditional marriage customs, in fact, from the "tank U-turn" to the "one step nine turns" change, has made it from a technological innovation, has become a cultural creation, let us see another possibility brought by science and technology, and this can also be seen as a microcosm of science and technology to change our lives.
In today's society, technology has penetrated into every aspect of people's lives. Not to mention that all kinds of "cyber worship Buddha" and online ancestor worship have begun to show an increasingly common trend. One of the main features of Apple's Vision Pro this year is spatial video, although we haven't seen too many specific applications in this area yet, but it is obvious that spatial video is also very suitable as a good medium for wedding records, and it is not impossible to become a new project for wedding companies, which is worth looking forward to.
