The shape of the car is a matter of opinion. It can be said that there are a thousand Hamlet in the eyes of a thousand people, and each person's aesthetic is different. However, in the eyes of automotive engineers, good-looking cars are traceable, specifically the following four standards: Any artwork is not the result of random patchwork. A good artwork can have a strong echo between the various components. This is what we often say. For example, the Land Rover Range Rover Aurora headlights and the down-pressure suspension roof are very responsive. Why do you imagine that if the headlights of this car are not slender and more folded toward the rear of the car, but the following headlights of the Land Rover Defender, how awkward it is. Looking at the headlights alone, the Land Rover Defender's square headlights are really not particularly attractive, and even have some old-fashioned autumn, but this is the sense of squareness, echoing the steady atmosphere and fortitude of the whole vehicle. The lights are integrated with the whole car, making people want to stop. In order to cater to the overall sense of failure, there are also a few failures, such as the BMW 3 Series began to use, and gradually spread to the X3, X5, 4 series, and now the open corner design in the 7th and 5th series. German designer Christopher Weil dominated the open-eye design, and he said he hopes to strengthen the connection between the kidney grille and the headlights, highlighting the overall sense. The design inspiration comes from the BMW E21 and E30. The earliest BMW 3 Series headlights and black decorative panels are a whole, so it can be understood that the entire headlights and kidneys form an integrated front face. The open-eye design has become BMW's new family design language, but the opponent of this design is unprecedented. The open-eye corner completely destroys the beauty of BMW, so a staunch handsome man is opened his eyes, at least the horizon. Jun is very timid. The body proportion is divided into two aspects: 1. Body posture; 2. Whether it conforms to the vehicle positioning. Let's talk about the body posture first. Among the non-luxury brands, the car manufacturers who know the most about car design are not Mazda. In recent years, the design of the soul can be said to lead the trend. The first to use the concept of soul modeling is the four-door concept car launched by Mazda in 2011 - Shinari. Its design language is called Kodo, and the Japanese meaning is "the soul of sports", which is the soul design that we often say later. The Shinari design concept is based on the cheetah and highlights the sporty style. As far as the real car is concerned, the whole car line is tense and powerful, and the first and last echoes, like a cheetah struggling to run forward. The natural body lines give it a richer expression, but the essence of this design lies in the perfect body posture. Contrast the Fiat MulTIpla listed in 1998, because the exaggerated style was once controversial and the sales were once unsatisfactory. Tianya Jun has not yet understood the awkward front face that is completely out of touch with the whole car. What are the advantages? For example, if Geely Borui is called the most beautiful Chinese car, the key point is that the proportion of the body is very harmonious, the body waist line is full of fortitude, and the design of the tail eagle hits the sky is more layered. The car is like a person. If you are in a position, you have to have the qualities that should be in this position. Otherwise, it will look uncomfortable and the users will not buy it. Explained in the car language is: the car is designed to meet the market positioning of the model, which car should have what car. For example, sports cars should be full of power; home cars should reflect a warm, smart image; and the lines of off-road vehicles should reflect the sense of bravery and heroic. Like the Ford Raptor F150 Or Toyota smooth It is a good example of the powerful and powerful sense of a pickup truck. Of course, there are also cars that are not logically shaped, such as the Volkswagen TristarR concept car. This concept car is built to commemorate the 30th anniversary of the Volkswagen Classic Syncro series (Volkswagen T-Series four-wheel drive and pickup). What makes Tianya Jun confused is that, besides off-road tires, where can this car be hooked up with a pickup truck? After a careful study, I can't help but discover a magical coincidence. The TristarR concept car and the Volkswagen T5 van are quite similar. Of course, it's not just the Volkswagen TristarR concept car that is confusing. For example, the following Weber Faster One sports car tells us exactly what is a failed car design. At first glance, the front face of this sports car and the old man with a big beard are really similar. It’s a disaster for a sports car to lose its handsome and bloody enthusiasm and change to the shape of a bearded old man. The low drag coefficient is especially important for cars. It not only improves the stability of the car while driving, but also reduces driving resistance and fuel consumption. The drag coefficient is calculated based on the wind tunnel test results. When the vehicle is tested in the wind tunnel, the wind speed is used to simulate the speed of the car while driving, and then the test instrument is used to determine how much force the car needs to resist the wind speed. The wind resistance keeps the car from being blown back by the wind. Based on experimental analysis, the engineers summarized the formula for calculating the drag coefficient: Wind resistance coefficient = (air resistance & TImes; 2) / (air density & TImes; windward surface area & TImes; speed 2) It can be seen from the formula that since the air density and the vehicle speed have always been variables and are not controlled, reducing the windward surface area of ​​the car has become a major event. There are many ways to reduce the windward surface area; 1. The car design should be more streamlined and smoother, and the body accessories should be small and concealed. This ensures that the air can pass through the vehicle body more easily and smoothly, and there is no large turbulence in the tail (the proportion of the body appearance, etc., which affects the air resistance by 40%); 2. The wheel should not be too wide and the wheel chamber should not be too deep (the wheel chamber has an amazing 30% impact on air resistance); 3. The bottom layout of the car body is reasonable, and the exhaust pipe and other components should be as flat as possible, which is beneficial to the passage of air from the bottom of the car (the air resistance brought by the bottom of the car body accounts for 20%); 4. The design of the intake air of the front is reasonable, and it is enough to ensure that enough air enters the cooling system. Excessive air enters the opposite direction (the air resistance caused by air entering the car accounts for 10%). In general, the drag coefficient of most cars is around 0.3, the drag coefficient of a better streamlined car can reach below 0.28, and the car can be reduced to 0.15. Previous studies have shown that for every 10% reduction in air resistance, it can reduce fuel consumption by more than 2.5%, which is considerable. Like the well-designed Mercedes-Benz IAA concept car, the drag coefficient can be reduced to 0.19. Is there a more mature design language? As a mature brand, being able to have its own design language is the foundation. No one wants to buy a car that others can't recognize. For example, BMW's kidney grille. Mercedes-Benz louver grille Cadillac's diamond cut. The excellent family design language is already rooted in the car as a whole, so that we can recognize it at a glance. Domestic brands are now working hard to build mature design languages, such as Geely and Roewe's family-style front faces, but this is limited to local languages, such as Cadillac diamond-cut bodies and BMW flame surfaces, which have not yet been formed for a richer design language. The development of automobiles has only been a hundred years. From the Mercedes-Benz No. 1, cars that have been modified by horse-drawn carriages have been arguing with hundreds of flowers. We have more choices in addition to automobile performance. Although the car shape is a matter of opinion, the beautiful and practical design is traceable. You may wish to take these standards and see if your favorite car meets these requirements.
