The international roughness index (IRI) is the roughness index most commonly obtained from measured longitudinal road profiles. It is calculated using a quarter-car vehicle math model, whose response is accumulated to yield a roughness index with units of slope (in/mi, m/km, etc.).
Height adjustable suspension is a feature of certain automobile suspension systems that allow the motorist to vary the ride height or ground clearance. This can be done for various reasons including giving better ground clearance over rough terrain, a lower ground clearance to improve performance and fuel economy at high speed, [1] or for stylistic reasons.
The Insurance Institute for Highway Safety and Highway Loss Data Institute (IIHS-HLDI) is an American nonprofit organization.It was established in 1959, and it is noted for its safety reviews of vehicles in various simulated traffic situations, including the effectiveness of a vehicle's structural integrity and safety systems during a collision, in addition to examining improvement on such ...
Most passenger cars are produced such that one or two inches of lowering will not significantly increase the probability of damage. On most automobiles, ride height is modified by changing the length of the suspension springs, and is the essence of many aftermarket suspension kits supplied by manufacturers such as KW, Eibach, [5] and H&R.

An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
Suspension design is often a compromise between ride quality and car handling because cars with firm suspension can result in greater control of body movements and quicker reactions. Similarly, a lower center of gravity is more ideal for handling, but low ground clearance limits suspension travel and requires stiffer springs. [10]
Independent suspension systems offer the advantage of lower unsprung mass to improve roadholding, and when properly designed, the ability to maintain the roadwheels perpendicular to the road surface during cornering and in response to uneven road surfaces, further improving roadholding. The reduction in transfer of vertical undulations in road ...
