What is the standard size of a sedan?

[DeKeira]

Standard sedan sizes are categorized into several classes. For household vehicles, the length typically ranges between 3800mm to 4300mm, width between 1600mm to 1800mm, and height between 1400mm to 1600mm. Below are the relevant details: Length: Length is the most influential parameter affecting a vehicle's purpose, functionality, and ease of use. Therefore, vehicle classes are generally determined by length. A longer body means more longitudinal usable space. Width: Width primarily affects passenger space and maneuverability. For passenger sedans, if three seats arranged side by side are to provide a spacious feel (primarily sufficient shoulder room), the width generally needs to reach 1.8 meters. In recent years, due to increased safety requirements, the thickness of door panels has increased, leading to a general increase in vehicle width. Height: Vehicle height directly impacts the center of gravity (handling) and space. Most sedans have a height below 1.5 meters, significantly lower than the natural sitting height of a human, mainly to lower the vehicle's center of gravity and ensure stability during high-speed turns to prevent rollovers. Wheelbase: Once the vehicle length is determined, the wheelbase is the most critical factor affecting passenger space. In terms of driving performance, a longer wheelbase enhances straight-line cruising stability but reduces steering agility and increases the turning radius. Therefore, a balance must be struck between stability and agility to achieve an appropriate equilibrium.
