What is the standard width dimension for cars?

[EmersynLee]

Width ranges between 1600mm and 1800mm. Below are relevant introductions to car dimensions: 1. Vehicle height: The distance between the highest point of the vehicle and the vehicle support plane. 2. Vehicle width: The distance between two planes parallel to the vehicle's longitudinal symmetry plane and respectively touching the outermost rigid fixed protruding parts on both sides of the vehicle (excluding rearview mirrors, side marker lights, position lights, turn signals, etc.). 3. Vehicle length: The distance between two vertical lines perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle. 4. Wheelbase: When the vehicle is in a straight driving position, the distance between two vertical lines of the vehicle's longitudinal symmetry plane from the ground contact center points of the wheels on two adjacent axles on the same side.

I've reviewed many car model specifications, and the width of ordinary sedans typically ranges between 1.7 to 1.9 meters. For common models, compact cars like the Corolla are approximately 1.78 meters wide, while mid-size sedans such as the Accord measure around 1.86 meters. SUVs tend to be wider than sedans, with compact SUVs generally ranging from 1.85 to 1.92 meters. Full-size SUVs are even wider, with large models like the Lincoln Navigator exceeding 2 meters in width. Pay special attention to these dimensions when selecting a car, as many underground parking garages have height limits of 2 meters, making it easy for overly wide vehicles to scrape when entering. It's best to bring a tape measure during test drives at dealerships and compare the measurements with your parking space dimensions.

Regulations on vehicle width vary significantly across countries. For instance, most EU regions limit it to within 2.55 meters, the US permits up to 2.6 meters, while Japan has a unique restriction of no more than 2.5 meters. In China, according to the GB1589 standard, ordinary passenger cars are not in violation if they do not exceed 2.5 meters. Trucks and buses have special rules, with tour buses allowed to be up to 2.55 meters wide. These regulations are not arbitrarily set; they must balance the need for navigating narrow urban streets with ensuring safe spacing for dual-lane parallel driving. The width-limiting gates at highway toll stations are typically around 2.2 meters, requiring oversize vehicles to detour to dedicated lanes.

In the field of automotive design, vehicle width is more than just a measurement number. We need to balance multiple factors: widening the chassis can improve cornering stability and provide more space for the suspension system; wide-body designs enhance visual impact; however, excessive width increases the drag coefficient, affecting range. Currently, electric vehicle platforms are adopting wide-body layouts primarily to accommodate more battery modules. For example, pure electric vehicles like the BYD Seal have a width of 1.87 meters, which is about 3 centimeters wider than comparable internal combustion engine vehicles. During design, attention must also be paid to protruding components such as door handles and side mirrors, which are included in the total width, to avoid exceeding regulatory limits.
