What is the appropriate ground clearance for an SUV?

Generally, the ground clearance of SUV models ranges between 200mm and 250mm. Introduction to ground clearance: Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding the wheels) and the supporting surface when the vehicle is fully loaded and stationary. It is used to characterize the vehicle's ability to pass over obstacles such as stones and tree stumps without collision. The smaller the ground clearance, the worse the ability to overcome obstacles. Sedans typically travel on flat urban roads, so they have smaller ground clearance. Off-road vehicles have larger minimum ground clearance to allow them to pass over larger obstacles. The greater the minimum ground clearance, the stronger the vehicle's ability to pass over obstacles or uneven terrain, but the higher center of gravity reduces stability. Methods for measuring ground clearance: An automated detection system composed of position sensors, computers, cameras, and lights is used to measure the minimum ground clearance.
Currently, mainstream urban SUVs generally have a ground clearance between 180-220mm, which is the most practical height for city driving. They can handle speed bumps and curb climbing without issues, and the chassis is less likely to scrape when parking. If the clearance is too high, the body tends to sway and the vehicle may feel unstable when cornering. If it's too low, the undercarriage is prone to scraping. My neighbor's Tiguan has a 190mm clearance, and it easily handles dirt roads and small ditches when taking the kids out on weekends. Modifying to increase the height actually affects the factory-tuned stability and isn't really necessary.
