A car’s ground clearance is the distance between the lowest point on the vehicle (usually the underside of the chassis) and the ground. It is important because it determines how high the vehicle sits off the ground, and can affect its ability to navigate uneven terrain, such as speed bumps or rocky roads. A higher ground clearance is ideal for off-road vehicles, while a lower clearance can improve fuel efficiency and handling on paved roads. However, a very low ground clearance can be a hindrance to driving in areas with frequent potholes or rough road conditions.
