AWD, 4WD, F/R WD for “normal” bad driving conditions

146 views

Normal bad driving conditions are heavy rain, snow, and ice, commonly found on the roads during periods of bad weather. Not offroading, climbing rocks, etc.

What exactly makes AWD/4WD that much better than FWD/RWD?

Why is 4WD better than AWD? Don’t you have to “turn it on” and if so, isn’t that worse if you hit a patch of ice/standing water/whatever, than AWD?

I vaguely understand that all axles vs only the front/rear axles are engaged, but I don’t understand the difference between AWD and 4WD, and not really why some roads are “chains required unless AWD/4WD” – is it that much safer that you wouldn’t need chains on the tires?

AWD is really more of a marketing term for cars that have “always on” 4WD, like some Subarus. The term 4WD is typically for when you can turn it on or off. It’s good for slippery conditions because it gives you more ability to push the vehicle in the desired direction.
