What does the minimum ground clearance of a car mean?

The minimum ground clearance of a car refers to the distance from the lowest point of the chassis to the ground when the vehicle is fully loaded (maximum allowable load mass). Minimum ground clearance for family cars: The minimum ground clearance for general sedans is usually between 100mm and 150mm. The greater the ground clearance of a sedan, the better its passing performance, but the worse its high-speed stability. For ordinary family sedans, as long as there are no high slopes, deep pits, or obstacles on the road, a large ground clearance is generally not required, as long as it ensures the comfort and stability of the vehicle. Sports car ground clearance: The ground clearance of sports cars is usually around 100mm. Sports cars have low ground clearance to improve tire grip and enhance the vehicle's speed and stability during high-speed cornering.
Ground clearance simply refers to the distance between the lowest point of the car's underbody and the ground. The official data for my SUV is 210mm, which I truly appreciated during my last trip on muddy rural roads—I didn't have to worry about scraping the undercarriage when crossing puddles, unlike the sedan in our convoy that kept clanking. This figure is usually listed in the chassis parameters section of the manual, measured in millimeters. Note that when fully loaded (with a packed trunk), the clearance may reduce by about 10%. If you frequently drive on rough roads or enjoy road trips, prioritize models with at least 180mm clearance. As a friendly reminder, always slow down below 20km/h when crossing speed bumps—hitting them at full speed can damage the exhaust pipe.
I had no idea what ground clearance was before buying a car, but the salesperson later explained that it's the minimum height from the car's chassis to the ground. For example, sedans typically have a clearance of 120 to 150 millimeters, while SUVs can have 180 to 220 millimeters. This parameter directly affects the vehicle's ability to pass through obstacles: last time in the mall's underground garage, my neighbor's low-clearance sedan had its exhaust pipe submerged in water, while my 160mm-clearance station wagon drove through easily. Remember to measure on level ground—the area between the front and rear axles is the most prone to scraping, and insufficient tire pressure can also affect the actual clearance height.
Fellow car enthusiasts often ask me about the minimum ground clearance, which essentially refers to the vertical distance between the lowest point of the chassis and the road surface when the vehicle is stationary. Off-road veterans know the importance of this parameter: 180mm can handle ordinary rough roads, while 200mm or more is needed to confidently tackle muddy terrain. My modified off-roader boasts 230mm, but the trade-off is needing to be cautious about body roll during turns. Factory data is typically measured under standard load conditions, but the vehicle can sag 2-3cm when fully loaded. Upgrading springs can indeed increase clearance, but it accelerates suspension wear. Beginners should focus on the 'ground clearance' value in the official specifications when choosing a car.
