haha what are you seriously trying to say that a focus is as good as a 4x4 in the snow?
I have owned 5 cars in my life. RWD, FWD, AWD and 2 4x4's one was a 4cyl and one is a V8. All of them either had winter tires or all-terrain tires (except for the new truck). Hands down the best two cars in the snow/ice were the little truck and the subaru. The FWD car was OK in the snow, and yes with good driving you could get up a lot of stuff, but it did have it's limitations. The RWD car was always full of sandbags, and again I could surprisingly get up a bunch of stuff with good driving, if you consider having to back up the ski hill road good driving.
I'm gonna give you a quick lesson in physics here. The reason you move when you are driving is because of the static friction between your tires and the road, if too much force is applied your tires will slip. The maximum force you can apply depends on both the amount of weight the tire is supporting, and how good the tires are/how slippery the road is. To go up something like a hill, you need to exert enough force to oppose the force of gravity. In a car driving with 2 wheels, all of that force must be applied to 50% less tire area than a car driving with 4 wheels. A FWD car is better than a RWD because it has more weight to help improve the friction. If all other things are the same though, there will be a point where the amount of force that the friction can apply, is not enough to move you up the hill, and any more force applied by the engine will just cause your wheels to spin. If that total amount of force can be spread to 4 tires though, then the force of friction that each tire has to apply is decreased. (OK that's not really good physics the way I explained it but is nevertheless true to some extent)
That's why AWD kicks so much ass, it allows most of the power to be where you want it (the front) but still allow some to move the back wheels when you need it. It's no secret that the best system for off-road or snow is a 4WD vehicle, but for the majority of people (who have no idea how a car works) AWD is actually going to benefit them more IMO.
