The calculation method of wheelbase is obtained by measuring the horizontal distance between the center point of the front wheel and the center point of the rear wheel. This distance is usually measured in millimeters and is one of the important parameters in vehicle design, which directly affects the passenger space and driving stability. A longer wheelbase typically provides a smoother driving experience and more spacious rear legroom, while a shorter wheelbase helps improve the vehicle's flexibility and turning radius, making it suitable for urban driving. It should be noted that longer wheelbase is not necessarily better, as excessively long wheelbase may affect vehicle passability, especially in narrow or multi cornered road conditions. In addition, wheelbase can also affect the distribution of the vehicle's center of gravity, which in turn affects handling and comfort. When choosing a vehicle, one can weigh the length of the wheelbase according to personal needs. For example, family cars may focus more on space, while sports vehicles pay more attention to handling performance.
