Generally speaking, the minimum ground clearance of a sedan ranges between 110mm and 130mm. For sedans, a larger ground clearance (exceeding 130mm) provides relatively better off-road performance but poorer high-speed stability; conversely, a smaller ground clearance (below 110mm) offers better high-speed stability but poorer off-road capability. If you frequently drive on mountain roads, it is advisable to choose a vehicle with higher ground clearance. If you mainly drive on urban roads or highways, a vehicle with lower ground clearance is sufficient. Additional Information: 1. The lowest ground clearance of most sedans is only about a dozen centimeters, which refers to the distance between the lowest part of the vehicle and the ground (usually near the suspension close to the tires). Other parts of the vehicle are positioned much higher. Therefore, when driving through rough or uneven terrain, it is important to choose your path carefully. Even when passing through low-lying areas, as long as the area near the tires is not at the lowest point of the depression, the chassis will not scrape. 2. The value of the minimum ground clearance has certain limitations and is related to the vehicle's function and aerodynamics. Arbitrarily increasing or decreasing the minimum ground clearance without considering the vehicle type can affect the car's performance and make the overall appearance look uncoordinated and awkward. The ground clearance of a car is not a fixed value; it depends on the load condition. Therefore, determining the ground clearance also depends on the changes in load, and the maximum load variation should be considered when setting the ground clearance.

For ordinary family cars, the ground clearance is generally between 110-150 mm, depending on what car you drive. Japanese cars used for grocery shopping and school runs have lower chassis for better fuel efficiency, while German cars are relatively higher. The chassis height can differ by two to three fingers when empty versus fully loaded! Last month, I drove my friend's Civic through muddy village roads, and the chassis scraped loudly. Later, I specifically measured the empty ground clearance at only 135 mm. Remember to slow down on rough roads and cross speed bumps diagonally to reduce the risk of scraping the undercarriage. When changing tires, avoid choosing ones that are too thick, as they may cause rubbing against the wheel arches, leading to more trouble.

When it comes to ground clearance, what impressed me most was driving my father-in-law's Camry back to the countryside. The official data of 152mm seemed decent, but the chassis still got scraped by stones when crossing field ridges. Nowadays, most new cars have a range of 120-150mm, with sporty sedans like the Mazda Axela only offering 131mm. Pay special attention when fully loaded—the actual height decreases by about 20mm as the suspension compresses. Enthusiasts who modify their cars often install shorter springs to lower the body, but this further reduces ground clearance. When washing your car on weekends, you can use your fist to measure—four fingers' width is roughly 80mm, and you'd want at least six fingers' worth for safety.

After measuring dozens of car models, the data shows: Class A cars generally have 130-140mm ground clearance, while Class B cars range from 140-150mm. But don't just rely on manufacturers' claimed figures. The Toyota Corolla has 135mm when unloaded, but drops to 115mm after seating five people due to spring compression. Tire wear to the warning line can further reduce clearance by 5mm. My cousin frequently scraped the undercarriage with his modified car until he spent 3,000 yuan installing metal skid plates for peace of mind. Remember, body-on-frame off-road vehicles can exceed 200mm clearance, while regular sedans need extra caution with obstacles over 15cm high.
