It must be noted that "4motion" is a trademark, and does not imply which particular 4WD system technology is being employed on a particular car model.
Volkswagen parent company Volkswagen AG has used different trademark names for their various brands of 4WD vehicles. Previously, Volkswagen cars used the term "Syncro", but currently they only use the term "4motion".
For their Audi branded cars, they use "quattro". Sister companies Škoda simply uses the nomenclature "4x4" after the model name, whereas SEAT merely uses "4".
It is important to note that none of the above trademarks or nomenclatures define the operation or type of 4WD system.
