Sport Utility Vehicle
(SUV) is a generic marketing description for a vehicle similar to a station wagon but built on a light-truck chassis.[1] Usually equipped with four-wheel drive for on or off-road ability, some SUVs include the towing capacity of a pickup truck with the passenger-carrying space of a minivan. SUVs are considered light trucks and often share the same platforms of pickups and thus are regulated less stringently than passenger cars under two major laws in the U.S.—the Energy Policy and Conservation Act for fuel economy standards, and the Clean Air Act for emissions standards
It is known in some countries as an "off-road vehicle" or "four-wheel drive", often abbreviated to "4WD" or "4x4", pronounced "four-by-four". However, not all SUVs have four-wheel drive capabilities. Conversely, not all 4WD passenger vehicles are SUVs. Off-road vehicles are a very different class of vehicles, being vehicles primarily built for off-road use. However this distinction is often not made by the general public and in the media. Although some SUVs have off-road capabilities, this is often a secondary role and they often do not have the ability to switch between 2WD, 4WD high gearing and 4WD low gearing. While automakers frequently tout a particular SUV's off-road prowess with advertising and naming, the daily use of SUVs is largely paved roads and urban areas. This also causes the term SUV to be used as a denigrating term by owners of "real" off-road vehicles.
Initially extremely popular in the late 1990s and early 2000s, the SUV's popularity has since declined. Due to high oil prices and a declining economy since the mid-2000s, manufacturers have responded to buyers' complaints. The traditional truck-based SUV is gradually being supplanted by a new vehicle type, the crossover SUV, which uses an automobile platform for lighter weight and better fuel efficiency.
