Sport utility vehicles (SUVs) are vehicles similar to station wagons; however, they are built on a light truck chassis. Some SUVs are equipped with four-wheel drive for off-road capability. Crossover SUVs (CUVs) appearing in the HD Universe are also included in this category. Crossover SUVs are built on a unibody chassis, usually sharing its platform with a sedan. The car-like nature of CUVs make them unsuitable for off-road use.
