The main benefits of 4WD are traction and power. ... 4WD improves traction in dangerous driving conditions, such as snow, ice, rocks, and other scenarios that can make control difficult. By engaging both sets of wheels, traction and control improves. Additional weight contributes to better grip on the road.

Why is it bad to drive in 4 wheel drive?

Technically, you could drive in 4WD on any paved road, but the problem is that you'll be locking the differential ration between your wheels. That can be dangerous when you're trying to turn the vehicle and need the wheels on either side to move at different speeds.

Does 4 wheel drive make a difference?

Because all-wheel drive and four-wheel drive send power to all four wheels, rather than two, they do provide roughly twice as much traction as a two-wheel-drive vehicle for accelerating in slippery conditions. But these systems help only with accelerating the vehicle on snow-covered or icy roads.
