right. 4-motion was VW's trademark name, and Quattro was the Audi trademark name, for AWD.
just like the Audi TT which is called Quattro but in reality it is transverse Haldex based.
4motion is a registered trademark of Volkswagen AG, used exclusively on Volkswagen-branded automobiles which utilise four-wheel drive (4WD) systems. Volkswagen has previously used the term "Syncro" for its 4WD models.
Of the Volkswagen Group's other marques, the "quattro" nomenclature is used for 4WD Audi cars. Sister companies Škoda simply uses the nomenclature "4x4" after the model name, whereas SEAT merely uses "4".
None of the above trademarks are specific to any particular 4WD system or technology being employed.
