The AWD system on the Q4 was co-developed with Steyr-Puch. The system consisted of a viscous coupling unit, central epicyclic differential and Torsen differential in the rear. It was connected to the ABS and Motronic engine management computers, which managed the torque split front to rear and side to side. The Q4 was never sold in the U.S., so this car being a 1995 is just a couple of years short of the 25 year exemption (those lucky Canadians and their 15 year rule). The central question is: peel the "4" off the rear badge and sneak it in as a 164Q or rent a garage in Canada for the next 4 years?
