Hi since no one from the Audi Forum could help me try out here I wanted to know what the difference is between these two four-wheel systems. My second question: Does Subaru have a permanent four-wheeler like quattro or is it a 100% front-wheeler in normal operation and only switches the rear axle on like 4Motion???? I read that the Justy GX has a kind of 4Motion four-wheeler system but doesn’t know if that’s right Thanks
