Sport utility vehicle
a rugged automotive vehicle similar to a station wagon but built on a
light-truck chassis : suv. — called also sport-ute.
Originally, SUVs had four-wheel drive and lots of luggage room.
The idea behind the name is that as well as regular driving,
you also used SUVs for off-road travel (sport) and/or for carting stuff around (utility)
Sport-Utility Vehicles, better known as SUVs, use a body-on-frame design.
