In Europe, the term SUV has a similar meaning, but being newer than in the U.S. it only applies to the newer street oriented one, where-as  Jeep ,  Land Rover  or 4x4 are used for the off-roader oriented ones. Not all SUVs have four-wheel drive capabilities, and not all four-wheel-drive passenger vehicles are SUVs.
Although sport utility vehicles (SUVs) are now considered a separate class of vehicle, they are actually a hybrid cross between a truck and a station wagon car. The Mercedes-Benz ML 320 and ML430 are the only true SUVs, as they don't share a platform with any other car or truck. (See Shared Platforms, below.) Most SUV's are built on automobile platforms or chassis. The Corolla is the basis for Toyota's RAV4, while the Camry provides the platform for the Lexus RX300.
