More weight on the drive wheels, right?

Not quite. BMW has 50/50 weight distribution and all fwd cars have more weight on the front. I just think you have much more control with rwd in every situation including snow with the right tires

I mean under acceleration.. Doesn't the weight shift rearward, putting it over the drive wheels?

I'm thinking I'd get Dunlop Wintersport M3s for winter tires.. or Blizzaks.

Oh in that case your right. the weight does transfer rearward.
I like the blizzaks personnally

That's why I never understood the theory that FWD was better because there was "more" weight on the fronts...

Stupidity reared its head a great deal in those years.

55 MPH

FWD

Reynold's Wrap: it's not just for hats anymore.

FWD is better in slipper conditions for one major reason: the power is being applied to the wheels that are doing the steering.

To explain in a little more detail, if you are driving down a curvy road in the snow, there are obviously times that some of your 4 tires are going to lose traction. In a RWD car, the power is going to the rear wheels which are pointing straight at all times. So if your front tires lose traction, you will simply go straight off the road. In a FWD car, when you turn the front wheels to go around a curve, the power being applied is being pointed in the direction you want to go.

Of course if you have a good set of snow tires, then there is less chance of losing traction in your front wheels. But all things being equal, FWD is better in the snow.

Rearward weight shift due to acceleration, while true in theory, would happen after you accelerated, or started to accelerate. So, that meant you already had traction. If you are getting additional traction due to rearward weight shift, almost by definition, you don't need it. Accelerating slowly (like when you are on snow) won't produce any significant weight transfer, IMO.

The weight shift that does matter is while climbing a hill, at least if you are going forward. The best traction of all in that situation is a front wheel drive car, backing up a hill.
