Drivetrain capability Table by type

Drive train type	Dry road	On road light snow and rain with dry spots	Deep Snow	Off road capable
Rear Wheel Drive	Yes	Not well	Not well	No
Front Wheel Drive	Yes	Yes	Not well	No
AWD	Yes	Yes	Yes	No
Part-time 4WD	Only in RWD mode	Only in RWD mode	Yes	Yes
Full-time 4WD	Yes	Yes	Yes	Yes

Note!: For above table: AWD has no low range, Part-Time 4wd has no center diff but has low range, Full-time 4wd has a center diff and low range. Also note that ground clearance and break over angles can play a large role in deep snow. Note the above table assumes locking, torsen, or limited slip differential in center and rear where applicable. Alternatively, brake-based traction control systems may be utilized in AWD or 4wd.

Four-wheel drive drivetrain

Note the reason that part time 4wd can not be used in dry conditions or where there are large dry areas with ice is the fact that under dry conditions when accelerating, decelerating, or turning the speed of the wheels will vary from side to side and front to rear. Because part-time 4wd has no center differential it forces the front and rear wheels to turn at the same speed even on dry tarmac. This causes tremendous stress to both the transfer case and the drive train.
