" " As I understand it, the difference between "4WD" and "AWD" is that " the former cannot be used on dry pavement due to the lack of a center " differential, and therefore are part-time systems. (This is the case " with the early Subarus as well as the old Jeep 4WD wagons of the late " 1940s.) getting technical again, i'd class awd as a subset of 4wd, since in both cases all 4 wheels are powered. '4wd classic' is as you say. " Since all AMC Eagles have a center differential and can be left in " "4-wheel-drive" under all conditions, including on dry pavement, they " actually should be classified as "all-wheel-drive" vehicles. and they weren't, because 'awd' hadn't yet been coined. " Of course things get even more confused since AMC themselves used the " terms "Automatic 4-wheel drive," "4-wheel-drive," and "Select Drive" to " describe the Eagle's capabilitites. i've also heard 'fulltime 4wd' for similar systems of the era. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
