All-wheel drive has become one of the biggest selling points for vehicles that can defeat the winter. Put an AWD badge on an SUV, add a picture of it powering through a snowy road, and the message seems obvious: AWD means you're ready for winter.
While AWD can absolutely help a vehicle get moving and maintain traction under acceleration when the road is slippery, it cannot magically give the tires more grip when you're trying to stop or turn. And that's where the popular idea that AWD is automatically "better in the snow" starts to fall apart.
