Actually, a AWD system is usually asymetrical, as they use differentials to send differing ammounts of power to different wheels. 4wd will send the same amount of power to every wheel, because everything is fully locked down. Fully locked 4WD systems would be more symetrical, at least in my opinion (just don't tell Subaru's current marketing department)
I believe that the first generation Legacys are still technically AWD, as the car can continuiously move power around with differentials. I believe the pre-1990 Subarus had 4wd, whereas the post-1990 Subarus have AWD.
