What is the minimum ground clearance of a car?

Generally, the minimum ground clearance for sedans ranges between 110mm to 150mm, while for SUVs it is between 200mm to 250mm. Below are the specific details about a car's ground clearance: Concept: Ground clearance refers to the distance between the ground and the lowest rigid part of the vehicle's underside. The ground clearance of a vehicle varies depending on whether it is unloaded or loaded. Ground clearance is categorized into unloaded and loaded conditions. The ground clearance when loaded is also known as the minimum ground clearance, which refers to the shortest distance between the lowest protruding part of the vehicle's chassis and the ground when the vehicle is parked horizontally under the rated full load condition. Characteristics of Clearance Size: Ground clearance is related to the vehicle's load; the heavier the load, the smaller the ground clearance. Vehicles with lower ground clearance have a lower center of gravity but poorer off-road capability. Vehicles with higher ground clearance have better off-road capability. Apart from performing well on gravel or mountainous roads, higher ground clearance also helps prevent water from entering the exhaust pipe when driving through flooded roads and makes it easier to park on curbs or other parking spaces with height differences.
I always pay close attention to vehicle ground clearance data because I frequently drive on construction sites and rough roads, so I'm particularly concerned about the minimum ground clearance. This value refers to the distance from the lowest point of the chassis to the ground under full load. For ordinary sedans, it's typically around 110mm to 150mm, while SUVs range between 170mm and 250mm. My urban SUV has 180mm clearance, which handles ordinary bumps and ditches without any issues, but for real off-roading, I'd need to switch to a vehicle with modified suspension. This specification can be found in the owner's manual. I recommend checking it against your regular driving conditions before purchasing, as too low clearance risks scraping the undercarriage, while excessive height affects cornering stability. Changes in tire size also affect actual passability - this should be considered when upgrading to larger rims.
Many friends around me overlook the minimum ground clearance parameter when choosing a car, only to regret it later. When accompanying a relative to pick up their car last time, I noticed that the sporty sedan had a nominal clearance of 120mm, but only met the standard when unloaded. With the trunk fully packed, the actual measurement was barely over 100mm. In fact, this value is like the 'knee height' of a car—too low, and even going over a speed bump becomes a nerve-wracking experience. For regular family cars, a ground clearance of around 150mm is recommended for a balanced performance, ensuring you won't get stuck on curbs during grocery runs or school pickups, without sacrificing comfort like rugged off-road vehicles. Recently, I helped someone pick a station wagon with excellent passability—180mm ground clearance paired with full-time four-wheel drive, making it stable even on waterlogged roads during rainy days.
