Typical Body Structure Trends Of Automobiles

Box car
In 1915, the Ford Motor Company produced a car that was different from the horse model, and its appearance characteristics were similar to a large box, and it was equipped with doors and Windows, and people called this kind of car "box car". Because this kind of car resembles the shape of the European noblewoman used to travel together and some other occasions to carry the "sedan chair" type light seat, so it was named "car" in the catalog.
Beetle
In 1934, Professor Ray of the Fluid Mechanics Research Center used the method of testing model cars in wind tunnels to measure the air resistance of various bodies, which is a historic test. In 1934, the United States Chrysler Company first adopted a streamlined body shape design. In 1937, German design genius Fernand Porsche began designing a car similar to the Beetle. Beetles can not only crawl on the ground, but also fly in the air, and their body resistance is very small. Dr Porsche maximised the advantages of the Beetle's shape.
Ship-type car
In 1945, the Ford Motor Company focused on the development of new models, and after several years of hard work, finally introduced the historic new V8 Ford in 1949. Because this car changes the model of the previous car, the front fender and the engine cover, the rear fender and the luggage compartment cover dissolve in one, the headlights and the radiator cover also form a whole, the two sides of the body form a smooth surface, the car is located in the middle of the car, the whole shape is very like a boat, so people call this kind of car "boat car".
Fish car
In order to overcome the defect that the tail of the boat car extends too far back, and the strong air eddy effect will be generated when the car runs at high speed, people have developed a fish-shaped car that resembles the back of a fish. In 1952, the Buick brand car of General Motors opened the era of fish cars. If you just look at the shape of the back of the car, the fish car and the Beetle car are very similar. However, if you look closely, you will find that the Angle between the back and the ground of the fish car is relatively small, the tail is longer, and the air flow around the body is relatively smooth, so the eddy current resistance is relatively small.
Wedge car
Although the "fish ducktail" model partially overcomes the lift of the air when the car is driving at high speed, it does not fundamentally solve the lift problem of the fish car. After a lot of exploration and experimentation, the designer finally found a new model - the wedge. This model is the body of the whole forward and down tilt, the rear of the body as straight as a knife, this shape can effectively overcome the lift. The first wedge-shaped car to be designed was the 1963 Stibke Abenti, which was highly regarded by automotive shape design experts. In 1968, General Motors Oldsmobile Toronado improved and developed the Wedge, which was adopted by the Cadillac Eldo in 1968. The wedge shape is widely used mainly in racing cars. Because racing cars first consider the effects of issues such as hydrodynamics (aerodynamics) on the car, the body can be built entirely in wedges, with riding comfort as a secondary concern. For example, the Italian Ferrari in the 1980s is a typical wedge shape.
