A sport utility vehicle, or SUV is a generic specification for a passenger vehicle which combines the towing capacity of a pickup truck with the passenger-carrying space of a minivan or station wagon together with on or off roa ability. Most SUVs are designed with a roughly square cross-section, an engine compartment, a combined passenger and cargo compartment, and no dedicated trunk (i.e. a station wagon body). Most mid-size and full-size SUVs have three rows of seats with a cargo area directly behind the last row of seats. Compact SUVs and mini SUVs may have five or fewer seats.
