The ZF8 is in plenty of euro Audis as well, but only the big, expensive stuff since it's a longitudinal gearbox. The more common, smaller Audis would be on the MQB transverse platform that can't use the ZF8. And Audi has been using a dual clutch on some of their lower-end MLB cars.

Anything A6/Q7 and up is a ZF8 if it's an automatic.
