a RWD 2WD is probably the worst vehicle to have in adverse conditions (rain, snow, ice, mud, etc). One afternoon last winter I helped about a dozen cars free themselves from the snow in the parking lot at work. Of these cars, the HARDEST one to free was a jeep cherokee 2wd. Easiest? the little 2wd civics.
Front Wheel Drive vehicles have an advantage for a few reasons:
1). The weight is over the driving wheels, keeping pressure to the ground, which adds traction
2). You can turn the driving wheels. When traction goes away, you can turn the wheels and maybe have a better chance at traction at a different angle. Very helpful in snow.
3). There's a distinct difference between FWD and RWD when the vehicle loses control. in FWD when it fishtails, you can stay on the accelerator and it straightens out. in RWD do NOT do that, or it will oscillate out even more.
Any 2wd vehicle without a locking differential, AWD, or a limited slip really only has ONE driving wheel when push comes to shove. If any one wheel slips (mud, ice, snow), the vehicle stops.
A 4x4 vehicle will give you 2 driving wheels (one front, one rear). They would both have to be spinning in order for the vehicle to stop moving forwards. Much less likely. Plus, you get the advantages of:
1). Weight over the front wheels (which are driving wheels in 4wd/awd)
2). Low-Range gears (4LO). They don't give you more traction, but they do give you more torque when you have traction.
3). LSD, AWD, or Traction Control will keep more wheels turning, even when one is spinning.
