FWD often is better at getting moving in snow because FWD cars are front end heavy - the engine and entire driveline (tranny, diff, half-shafts, etc.) are in the front. RWD cars are more weight balanced merely as a consequence of design.

The RWD equivalent is loading the trunk with sand.

You should workout more, haha, just kidding.

Get snow tires any you'll be fine. I live in the city and found it hard to justify but I do it primarily for safety (new baby) and plus this way I give the summer performance tires a rest for a few months (last a little longer). Even for the few days it snows it's worth it.

Actually, summer tires are typically much better in the rain than all-seasons.

Add to that the fact that ratio in reverse is pretty steep. Too much torque, not enough weight.

you did turn off the traction control, right? that does not look like a lot of snow, but maybe just it appears that way on the pic

+1

Think "winter tyres" rather than snow tyres. Unless the temperature stays comfortably above freezing all year round, you should switch during the colder months (winter tyres are recommended below 7 degrees C). The cost is marginal in the long-term (your summer / all-seasons will last longer) but it's way safer in cold, wet or freezing conditions.

Plus, you get to snub all the RWD haters when the snow starts coming down!

i tried just about everything. going in forward, reverse, eco pro, comfort, sport, sport+, hitting DSC button, holding the button, going fast, going slow. it was just so slippery.

Judging by the picture your wheels are turned not straight. You could even have problems with snow tires.

Had a couple inches of snow and freezing rain today. This is my driveway, 200+ft and a pretty steep incline.


Today the Dunlop Sport M3's got me up no problem!

It's a long road. Now I can pinpoint where you live and pay you a visit.

LOL, hey if you are that determined, a beer and a friendly Springer Spaniel will be waiting to greet you.

That's so welcoming. I love Springer Spaniels. My favourite. I wish I could transport my 330d M Sport across for our two cars to bond!

Engine weight placement isn't the only difference between RWD and FWD. There's different frictional dynamics associated with "push" verses "pull". A 15' long wooden 2 x 4 will want to wiggle and squirm more when pushed up an incline, verses pulling it up an incline.

So putting cinderblocks in the truck will only help to a certain degree. You stil have to deal with the pushing motion.

This. FWD cars are often 65% weight over the front axle, because it's engine, transmission, diff, etc, all up front. RWD cars are closer to 50/50 because the diff is in the back, and some driveline parts help balance the car.

The *only* reason FWD cars are in *any* way better in the snow is due to the additional weight over the drive wheels. This can be achieved in RWD by throwing weight in the trunk.

Note that when you climb a hill with a car, the weight shifts rearwards, so FWD loses its advantage the steeper the hill gets, and RWD gets closer to parity.

Starting with 'only' 50% of your weight over the rear wheels, then backing up a hill, is the worst of both worlds. Now you've got (say) 45% of the weight over the drive wheels.

One major advantage of RWD in poor weather is you aren't trying to accelerate and steer with the same wheels. It sucks when you're driving FWD in slippery conditions, turning slightly, and suddenly the wheels break lose.. now you have no forward drive OR steering.

I see your point, but it doesn't really apply here. The issue isn't the 2 x 4 itself in your example, but the motivational force trying to move the 2 x 4. It's easier to push something up a hill when traction is limited than it is to pull it up the same hill. Weight transfer is a far more significant factor than the friction of the object you're moving.

And besides, the car is on wheels. Friction is essentially zero. In fact, friction IS zero in this case. Thus the reason for the thread in the first place...
