Do you know why the chassis of a sports car is so low? What is the principle?

The chassis is lower than ordinary sports cars. Considering its usage scenario, this is a very reasonable design method. Sports cars have poor passability and strict requirements on road conditions, which are only applicable to highways and urban road conditions. However, cars are endless. Every car has its own characteristics. If you want to make a sports car cool, awesome and passionate about speed, you must compromise between the passability, economy and comfort of the vehicle. So the chassis design of sports car is not unreasonable. Different models meet the needs of different customers. Under similar questions, I usually miss a point in the answers I see. Even if there are some answers called university teachers, this is not taken into account. As a relatively professional person, I don't think it is appropriate.

The chassis is low at two o'clock, not one. The chassis is low, the first point is that the clearance between the vehicle and the ground is the smallest; The second point is that the distance from the wheel center to the wheel brow is low, and the term should be called low driving height. Refers to the small jump stroke on the suspension. Don't go straight up and down the slope when driving. Try to cut into the slope from the side and go down the slope round and round, which is easy to scrape the bottom. Because most sports cars run on relatively flat roads or even on racetracks. This creates conditions for reducing the minimum ground clearance, because it does not have to worry about being stuck. Then why choose a smaller ground clearance? This problem is mainly considered from the point of view of aerodynamics.

Speaking of deep water, in order to avoid the engine from entering water, we need to pay attention to several issues: First, observe the water depth. Only when the water depth does not exceed 30~50cm can it be considered to pass, otherwise it will definitely cause serious consequences of engine water intake. On the contrary, pay attention to the road and see if there are other cars blocking it. If there is, don't go without authorization. When wading, don't release the throttle and shift gears in the water. It should also be appropriate to step on the gas pedal.

The airflow is divided into two parts from front to back, one part sweeps along the upper surface of the car from the hatch cover, windshield, roof and trunk; Another part of the airflow passes through the front and bottom. The greater the gap between the vehicle and the ground, the greater the airflow passing under the vehicle, which is the problem. According to the aerodynamic distance, the more airflow from the bottom of the car, the greater the lift of the car due to the interaction with the airflow from the roof. The greater the lift, the smaller the grip of the vehicle. It's like walking on ice. Do you think you can run fast? You must pay attention to the road conditions when driving a sports car. If the road conditions are good, you can naturally run fast. But for ordinary roads with complicated road conditions, don't drive too fast, otherwise it will be a big expense to run over the high-speed friction chassis and repair the car.
