When driving, the vehicle should only cling to the road surface with its wheels. This is one of the main factors for ensuring your ride comfort. The distance between the bottom of the car and the road is called the clearance.
Ground Clearance (also known as ride height) is one of the most basic but very important general dimensions of a vehicle. It is defined as the minimum distance between the lower end of the vehicle body (or chassis) and the road. In other words, it indicates the height of the lowermost part of the vehicle with respect to ground. Generally, most of the manufacturers specify this dimension in unladen vehicle condition i.e. without any load of cargo or passengers. That is why, in actual running condition, when you load the vehicle with passengers and cargo; the available ride height is always lower than specified.
On rough and bumpy roads, higher ground clearance is always better as it avoids scratching of the underbelly of vehicle. As a general rule, it could be observed that a specific body type of a vehicle has some standard for ground clearance. Sedans and high performance sports cars have very low ground clearance while hatchbacks are on thenext step of the ladder. SUVs secure the top position of the ladder by offering highest ride height.
- It is the trickiest dimension because vehicle handling directly depends on it. The higher the clearance, the higher is the position of Centre of Gravity (CG) of vehicle. And higher position of CG means that the vehicle is prone to roll over. That means vehicles with higher clearance have more possibility of turning over than the vehicles with lower clearance, thus affecting the handling. On the other hand, vehicles with lower ride height offer superb handling performance due to lower height of vehicle CG
- The car must be loaded, as in normal conditions - the driver's weight, the tank is slightly not full, the spare tire in the trunk and medium-sized luggage (up to 10 kilograms).
We put the car on the pit.
A level and solid object (a level is best) fits under the car across the width of the wheels. Suspension and brake elements are not taken into account when measuring, since they rarely cling to a car.
We measure the clearance at several points. And the first one is under the engine, namely in the lowest section of the motor protection (it should not be removed, since it prevents the ICE from critical hits against obstacles on the road). The second point is the stretcher. The level is placed under the car and the height is measured at several points. The smallest value will be the vehicle clearance. This is for the front.
