Crossovers, SUVs, 4x4 Off-Road. SUV is a sport utility vehicle. A sport utility vehicle or suburban utility vehicle (SUV) is a vehicle classified as a light truck, but operated as a family vehicle. They are similar to a large station wagon or estate car, 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 or large sedan. Popular in the late-1990s and early–mid-2000s, SUVs sales temporarily declined due to high oil prices and a declining economy. The traditional truck-based SUV is gradually being supplanted by the crossover SUV, which uses an automobile platform for lighter weight and better fuel efficiency. By 2010, SUV sales around the world were growing, in spite of high gas prices
