Car wheelbase

February 24, 2024

The wheelbase is the distance between the two midpoints of two adjacent wheels on the same side of the vehicle and is perpendicular to the two vertical lines of the vehicle's longitudinal symmetry plane. In short, the distance from the center of the front axle of the car to the center of the rear axle. For a three-axis or more automobile, its axis has a wheelbase between two adjacent wheels from front to back, and the total wheelbase is the sum of the wheelbases.

Before we say wheelbase, we must first understand the parameters of the vehicle length. As we all know, the captain generally refers to the length from the frontmost end to the rearmost end of the car. It is the parameter that has the greatest impact on the use, function, and convenience of the car. The length of the body means that there is a large space available for longitudinal use. This is obvious; however, a body that is too long will make it difficult to turn around and stop.

After the captain was identified, the wheelbase was the most important factor affecting the seating space, because in the vast majority of hatchback and sedan cars, the occupant's seat was arranged between the front and rear axles. The wheelbase refers to the distance between the front and rear axles, and many old riders also think approximately that the wheelbase is the distance between the front and rear axles of the car. The long wheelbase increases the longitudinal space of the occupant and benefits directly from the legroom, which has a great impact on ride comfort. In terms of driving performance, long wheelbase can improve the stability of straight-line cruise, but the steering flexibility is reduced, and the radius of turn increases. Therefore, a trade-off must be made between stability and flexibility to achieve a proper balance.
