Is a 120mm Minimum Ground Clearance Sufficient?

Minimum ground clearance of 120mm is sufficient. Minimum ground clearance refers to the distance between the lowest point of the vehicle (excluding wheels) and the supporting surface when fully loaded and stationary, indicating the vehicle's ability to pass over obstacles like rocks and tree stumps without collision. Generally, the minimum ground clearance for sedans ranges between 110mm and 150mm. For sedans, a larger ground clearance (over 130mm) provides relatively better off-road capability but poorer high-speed stability; while a smaller ground clearance (below 110mm) offers better high-speed stability but poorer off-road performance. SUVs typically have a minimum ground clearance between 200mm and 250mm. For SUVs, a smaller ground clearance (less than 200mm) results in poorer off-road capability and emphasizes highway performance, making them more like city SUVs; whereas a larger ground clearance (over 250mm) enhances off-road capability and focuses on field performance, making them more like pure off-road SUVs. Additionally, some high-end SUVs now come with adjustable air suspension, achieving a balance between handling and off-road performance.
I usually drive in the city, and a 120mm ground clearance is completely sufficient for me. The urban roads are smooth, making the ride comfortable with minimal bumps. However, I need to be mindful of curbs or speed bumps—if I go too fast, the chassis might lightly scrape, especially when the car is fully loaded. Light rain is no problem, but in areas with deep water accumulation, I have to drive slowly to avoid water ingress. When parking, the parking spaces aren’t high, so there’s no risk of getting stuck. Overall, it’s more than enough for daily commutes and grocery runs—just don’t push it too hard. Remember, driving habits matter—avoid slamming the accelerator on slopes, and during maintenance, have the underbody protection checked as well.
I'm into off-roading, and this 120mm clearance is really not enough! The terrain in the wild is complex, and with just a slightly steep slope or gravel road, the car gets stuck and can't move. Once, I almost got trapped in the mud and couldn't get out. Off-road enthusiasts all know that at least 150mm or more is necessary for safety. It's more practical for mountain roads, sandy terrain, or modified off-road vehicles. If it's just for occasional outings, 120mm might barely do, but the risk is high—it's easy to scrape the undercarriage, and repairs can be a hassle. I recommend frequent adventurers to install a lift kit or directly opt for a high-clearance model—it's worry-free and safer.
As a parent traveling with kids, a 120mm ground clearance is barely sufficient on urban roads. Children sitting in the back may experience some discomfort from bumps on uneven surfaces. Drive slowly in areas with many potholes—safety comes first. Be cautious of water accumulation during rainy days to avoid submerging the exhaust pipe. When choosing a car, I prioritized comfort, and a higher clearance provides a smoother ride. Regularly check the tires and underbody protection for maintenance.
