I don't think you know what an SUV is... Here is part of a definition from Wikipedia to help you out...
"A sport utility vehicle (SUV) is a generic marketing term for a vehicle similar to a station wagon, but built on a light-truck chassis.[1] It is usually equipped with four-wheel drive for on- or off-road ability, and with some pretension or ability to be used as an off-road vehicle..."
"...The term is not used in all countries, and outside North America the terms "off-road vehicle", "four-wheel drive" or "four-by-four" (abbreviated to "4WD" or "4x4") or simply use of the brand name to describe the vehicle like "Jeep" or "Land Rover" are more common."
