What are the advantages and disadvantages of a long wheelbase?

[Shannon]

Here are the advantages and disadvantages of a long wheelbase: Advantages of a long wheelbase: More spacious interior, especially in the rear seats; more stable at high speeds; Disadvantages of a long wheelbase: Lower body rigidity; heavier body weight, leading to higher fuel consumption; reduced cornering performance; increased risk of scraping the undercarriage. Introduction to wheelbase: It is the distance from the center of the front axle to the center of the rear axle. It is the distance between two vertical lines passing through the centers of adjacent wheels on the same side of the vehicle and perpendicular to the longitudinal symmetry plane of the vehicle. It is divided into fixed wheelbase, bogie wheelbase, and total wheelbase. The total wheelbase is the distance from the foremost axle to the rearmost axle and is a key parameter affecting the 'turntable length' of the train.
