You may find that the layout of the fuel tank of the car is not uniform. Some are on the left and some are on the right. The position of the fuel tank port of each car is different.Under normal circumstances, most of the fuel tank port positions of German cars are on the right, such as Volkswagen, Audi and BMW.The fuel tank port of Japanese cars is on the left, such as Honda and Toyota. Why is the fuel tank of a car divided between the left and the right? Is there a difference between them?　　​

　　In fact, speaking of it, whether the fuel tank of the car is on the left or on the right, it has no effect on the performance of the car itself.Since there is no clear regulation on the location of the car fuel tank, it is normal for some car fuel tanks to be on the left and some car fuel tanks to be on the right.　　​

　　Speaking of which side of the fuel tank is on, the biggest impact on the owner is when refueling.Speaking of the impact on refueling, in fact, it does not have much impact.When refueling, no matter which side you stop on, the length of the oil gun can be reached.　　​

　　The reason why there is a distinction between left and right is mainly based on the following reasons：

　　First, for the counterweight of the body.Body counterweight is of course an important consideration in automobile design. The more the center of gravity of the vehicle is in the center, the more stable the vehicle will be.Therefore, most cars use a rear fuel tank, which is to place the fuel tank under the rear seat.In this way, the counterweight of the vehicle can be balanced as much as possible to maintain the stability of the center of gravity of the vehicle.

　　Second, the driving direction is different.The location of the fuel tank port is closely related to the driving direction of different countries.Cars originated in western countries, and of course they will be designed according to the driving direction of western countries to facilitate roadside refueling.For example, in Germany and Sweden, vehicles are driven on the right, and the refueling ports for Mercedes-Benz, BMW, Audi, Volkswagen, and Volvo models are on the right; in Japan, vehicles are driven on the left, and for Honda and Toyota models, the refueling ports are on the left.
