vehicle length, width, and height.
1. Automobiles length
perpendicular to the longitudinal plane of symmetry of the vehicle, respectively, and abut against the front car, the distance between the two vertical faces of the outermost end of the protruding portion. Simply put, that is the direction the car forward, the distance to the forefront last end.
body length means longitudinally using a large space, front and rear leg room than the well-off people will not take the sense of oppression. But the body is too long will turn, U-turn and parking inconvenience, on the contrary, if the body is short, such as miniature cars, riding in front of people is often no way to straighten the leg while sitting in the rear passenger knee often to the top the front seat back, either the front row or the back row are prone to fatigue.
2. car width
is parallel to the longitudinal plane of symmetry of the vehicle, respectively, and the distance between the two planar abutment fixed to both sides of the projecting portion on the vehicle. Simply put, the left is the car most of the distance to the far right. Wherein said “fixed on both sides of the protruding parts” does not include mirror, side marker lamps, lamp position indicating lights, turn lights, fenders flexibility, anti-skid tire chain and the deformed portion in contact with the ground.
Effect of the width of the main passenger space and flexibility. For passenger cars, if requested three seats arranged transversely has a wide ride comfort (mostly adequate shoulder width), then the vehicle width are generally required to reach 1.8M. Due to the recent demand for safety, an increase in wall thickness of the door, and therefore the vehicle width is also generally increased. Take advantage of the body is too wide in the rear of the passenger will not feel crowded, greatly improving the comfort, but it will reduce car travel in urban areas, parking convenience, so for the sedan is a recognized vehicle width 2M It limits. Nearly two meters or more than two meters would be very difficult to drive the car. But the width of the car can not be too narrow, narrow front and rear row passengers will feel crowded, long travel is also easily gives rise to fatigue.
3. Car High
is the distance between the highest part of the vehicle support plane projection abutting against the horizontal plane of the vehicle. Simply put, it is the distance from the ground to the highest point of the car. Generally it refers to the high car in the car load height, but may be the case where the operation (refueled and coolant) is.
a direct impact on the ride height of the vehicle center of gravity and space. Most car height of 1.5 meters, and the height of the body’s natural sitting position is much lower compared to the expense of a lot of head room occupant, primarily due to lower center of gravity of the entire vehicle consideration, to ensure that no high-speed cornering overturned. MPV, van, etc. in order to create a broad headroom and cargo space, body height is generally more than 1.6 meters, but will increase the center of gravity of the vehicle, high-speed cornering is very easy to roll, this is the kind of car a high body major characteristics of the defect. In addition, most of the indoor parking has a height restriction, usually 1.6 meters, which also brought a certain height limit for the car in a car.
