Ground clearance refers to the distance between the lowest point of a vehicle's undercarriage and the ground. This measurement is crucial for determining how well a vehicle can navigate uneven terrain, such as rocks or potholes. Higher ground clearance typically allows for better off-road capability, making it a key feature for vehicles like SUVs and trucks. In addition to off-road performance, ground clearance affects a vehicle's stability and handling. Vehicles with lower ground clearance, such as sports cars, often have better aerodynamics and handling on smooth roads. However, they may struggle on rough surfaces, highlighting the importance of ground clearance in vehicle design and functionality.
