In fact, the cottage car is not a unique label of domestic car companies. Many car companies started with fake cars. It can even be said that some car companies can't even survive, let alone become stronger and bigger, without the cash flow and profits obtained from putting fake cars on the market.
Because the development of domestic automobile started too late, it is acceptable for some cottage car companies to appear, but these cottage car companies have not embarked on the road of self-research after grabbing a lot of profits.
Perhaps the fierce competition in the automobile market does not allow these car companies to have enough research and development time?
Perhaps the profit earned by the cottage car is not enough to support the huge expenses of self-research?
Maybe it's ... there are many reasons, but the road to self-study is undoubtedly an important reason. Let's briefly understand the steps of self-developed models, and maybe you will understand why some car companies would rather be scolded than independently develop.
Step 1: Conceptual design
The so-called conceptual design is what kind of car you want to build: car, SUV, MPV. Is the engine horizontal or vertical? Front drive or rear drive? Two-seater or four-seater or seven-seater? What is the size of the vehicle? Basically, the brain is wide open, and everything about the car is thought out first.
Step 2: Modeling and design
After the conceptual design is completed, the overall modeling design is carried out according to the conceptual design. Designers design different styles of vehicles through manuscripts and renderings, and then refine the styles. In today's increasingly valued market, the success or failure of styling design is almost related to the success or failure of vehicles in the future.
Step 3: Make a sludge model.
After the modeling design is completed, the three-dimensional model is made by professional software and adjusted according to the existing production level and other factors. After confirmation, make a sludge model according to the ratio of 1: 1. Through this primitive scale production, we can better observe the vehicles. After all, sometimes the design is beautiful but the real car is ugly, so the sludge model is essential. This oil-free and sludge-free industrial material is expensive, and in order to verify a drawing, several sludge models are often needed, which can be said to be a double consumption of time and money.
Step 4: Automotive Engineering Design
After the vehicle structure is determined, it is necessary to "decompose" the vehicle, such as how to arrange the whole vehicle, how to design the body frame, what requirements the engine needs to meet, and how to install the interior function buttons. In short, it is equivalent to writing a "manual" for vehicle production. As long as you follow the requirements of various parameters in engineering design, you can save a car.
Step 5: Test the sample car.
After the engineering design, cars can be produced, but they cannot be produced on a large scale. What if there is a major problem? In order to verify the reliability of vehicles, car companies need to produce some prototypes first, and then go to desert, snow and other environments for testing, including wind tunnel testing and other technical tests. In short, they drive cars to make them, and the R&D department adjusts the vehicles according to the feedback data of the prototype to achieve stable and reliable quality.
Step 6: Start mass production.
After there is no problem with the sample car test, the car company will start small-scale mass production, during which it is necessary to constantly adjust the production line of the factory to improve production efficiency; At the same time, small batch production is also to verify whether there will be some unknown problems in the production process of vehicles. After small-scale mass production is no problem, large-scale production begins.
After reading the above six steps, I believe everyone has a better understanding of building a car. In fact, for car companies, developing a car not only takes a long time, but also consumes a lot of money. Even more frightening is that it can't control risks. For example, it took three years to develop an MPV, but after the vehicle went on the market, it was found that the market outlet was not MPV at all, and it was very embarrassing to recover the cost because of poor sales.
In addition, for car companies, we can't wait for a car to be developed and listed before we start the research and development of another car, can we? So it is very difficult to develop vehicles by yourself.
The self-developed cottage car will not face so many problems. After buying a popular model and modeling by laser measurement, the rest is basically easy. There is no need for conceptual design and modeling design, and there is no need to develop any components forward. Just like a cat painting a tiger, the risk is small, the investment is small and the return is high.
After two comparisons, if you are the owner of a car company, will you choose a self-developed model or a cottage luxury car?
