- Ride height
Ride height (ground clearance or simply clearance) is the amount of space between the base of an automobile
tireand the underside of the chassis; or, more properly, to the shortest distance between a flat, level surface, and any part of a vehicleother than those parts designed to contact the ground (such as tires, tracks, skis, etc.). Ground clearance is measured with standard vehicle equipment, and for cars, is usually given with no cargo or passengers.
Ground clearance is a critical factor in several important characteristics of a vehicle. For all vehicles, especially cars, variations in clearance represent a trade off between
handlingand practicality. A higher ground clearance means that the center of mass of the car is higher, which makes for less precise and more dangerous handling characteristics (most notably, the chance of rolloveris higher). However, it also means that the car is more capable of being driven on roads that are not level, without the road scraping against and likely damaging the chassis and underbody. Higher ride heights will typically adversely affect aerodynamicproperties. This is why sports cars typically have very low clearances, while off-road vehicles and SUV's have higher ones. Two well-known extremes of each are the Ferrari F40and the Hummer.
armored fighting vehicles (AFV), ground clearance presents an additional factor in a vehicle's overall performance: a lower ground clearance means that the vehicle minus the chassisis lower to the ground and thus harder to spot and harder to hit. The final design of any AFV reflects a compromise between being a smaller target on one hand, and having greater battlefield mobility on the other. Very few AFV's have top speeds at which car-like handling becomes an issue, though rollovers can and do occur. By contrast, an AFV is far more likely to need high ground clearance than a road vehicle.
Lowering a car's suspension is a common and relatively inexpensive aftermarket modification. Many people prefer the more aggressive look of a lowered body, and there is an easily realized
car handlingimprovement from the lower center of gravity. Most passenger cars are produced such that one or two inches of lowering won't increase the probability of damage significantly. 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 Eibach, H&R, Tein, Intrax, and Spax. Self-leveling suspensionsystems are designed to maintain a constant ride height regardless of load. Vehicles not equipped with self-leveling will pitch down at one end when laden; this adversely affects ride, handling, and aerodynamic properties.
Some modern automobiles (such as Audi's Allroad Quattro) have adjustable suspension systems, which can vary the ride height by locating the suspension mounting points, depending on road conditions and/or the settings selected by the driver.
Other, simpler suspension systems, such as
coiloversprings, offer a way of manually adjusting ride height (and often, spring stiffness) by compressing the spring in situ, using a threaded shaft and adjustable knob or nut.
