I have driven this car in severe winter conditions and as long as you follow the rules of winter driving that apply to all cars (slow down, give more time to react to situations, downshift prior to braking, etc) you should do fine.
Braking and stopping ability is not determined by whether the car is RWD or AWD, since all cars brake the same way. The ability to take off from a dead stop in the snow and ice is what makes 4WD superior, however with good tires any car car handle snowy weather. The stock Goodyear Eagle RSA's are not too bad. They are an All Season tire, however they can be a bit tricky in the deep slick stuff. I used them and they worked just fine in normal Northern Michigan driving. Our police department uses RWD Dodge Chargers with no problems during severe weather. They use Blizzaks and these cars are complete snow tanks with them on.
