That FWD is the holy grail of bad weather control is really hogwash. I
lived in Michigan's lower peninsula for decades and near Copper Harbor
in the UP for one winter. I've also ice raced on frozen lakes.
FWD is great in the snow for one thing and one thing only. Accelerating
in a straight line. Once you add in turning you're losing traction
compared to RWD. Remember the traction circle. As long as all forces
(acelleration, braking and turning) stay within that circle traction is
good. Once the total of all forces extends past the traction circle you
are out of control. It is much easier to go past the traction circle
with a FWD vehicle because the generation of ALL three forces is the
front tires.
For instance, go into a corner on a snowy road a little too hot with a
FWD car. You have four choices.
1. Brake
2. Take your foot off the gas
3. Do nothing
4. Accelerate
Results?
1. If you are already going to fast to make the corner and you brake you
will slide towards the outside of the curve. Hopefully you won't hit
anything.
2. If you're not going to fast you'll slide and hopefully scrub off
enough speed to avoid hitting anything.
3. BANG!
4. Here's where the major advantage ot RWD in the snow comes out. With
FWD if you accelerate you will hasten your slide to the out side of the
corner, although it may be further up the road before you hit anything.
When you do hit it will be much harder though. With RWD when you
accelerate you can swing the rear end around and get straight with the
corner. However, this is something you need to be comfortable with
BEFORE you need it, especially with something as big, ponderous and tall
as an Aerostar. Still I feel MUCH more in control in any RWD then any
FWD in the snow. BTDT-GTTS.
Of course it's best to get accustomed to driving your vehicle in
snowy/icy conditions well before you really need to. I always suggest
taking your vehicle to a parking lot anytime it get snow cover to get
yourself aquainted with the vehicle dynamics AND your reactions.
